APPARATUS AND PROCESS FOR LAUNCHING REVETMENTS Filed May 25, 1946 2 Sheets-Sheet 2 ndrew FCr/fe# Patented Oct. A9, 19751 APPARATUS AND PROCESS FDR LAUNCHING REVETMENTS Andrew B. Pickett, United States Army, New Orleans, La.
application May 23, 1946, Serial No. 671,719 4 Claims. (Cl. 61-38) (Granted under the act of March 3, 1883, as `amended April 30, 1928; 370 0. G. 757) The invention described herein may be manufactured and used by or for` the Government for governmental purposes, without payment to me ofv any royalty thereon.
This invention relates to an apparatus for launching revetment mats over an area on a subaqueous river bank; more particularly it is directed to an apparatus of this character for laying roll-type revetment mats.
One of the objects of the invention is to provide a mooring barge having a mat launching or placing barge associated therewith, with a mat carrying barge associated with the mat launching barge and an anchor barge including means for unrolling the revetment mats down the slope of a river bank or the like.
Another object of the invention is to provide means on the mat launching barge whereby rollup unit sections of revetment mats may be unrolled and then rerolled on a large drum, with the unit sections being joined together while being rerolled on the drum.
In carrying out the invention, a plurality of unit revetment mat`sections are rolled up either on a core or without a core and taken by a material barge to a site of sinking operations Where the rolled-up'mat sections are removed from the material barge by a derrick and placed on a launching barge. The mat sections are then rerolled on a substantially large drum, the unit sections being'joined together by threading small cables through exposed loops thereon until a revetment vmat of a predetermined length is formed. The drum with the revetment mat rolled thereon is removed from the launching barge and rolled down the slope of a river bank, whereby the revetment mat is unrolled and laid on the bank for protecting the river bank against erosion, after which the drum is recovered and the operation again repeated.
With the above and other objects and advantages in viewthe invention consists of certain features of construction and operation of parts which will hereinafter be described and shown in the accompanying drawings in which:
Figure 1 is a vertical sectional view through an Figure 3 is a top plan view of Figure 1; and
Figure 4 is a perspective view of a unit section for forming a complete revetment mat of a predetermined length.
Referring more specifically to the drawings, a mooring barge I is provided which is arranged at right angles to a shore line S Fig. 1 and having connected thereto a mat placing or launching barge 2 and a material or mat carrying barge 3 adjacent to the outer longitudinal side of the launching barge. Both the launching barge 2 and material barge 3 are parallel to the shore S and at right angles to the mooring barge. The material barge 3 is adapted to have a series of. reinforced rolled-up type of flexible unit mat sections 4 loaded thereon, which are adapted to be transferred to the launching barge 2 by means of a traveling crane or derrick 5 mounted on tracks E extending longitudinally of the launching barge 2 along the edge adjacent to the material barge.
The launching barge 2 is provided with stands TI and 'I' with a large mat rerolling drum 8 rotatably mounted on the stand I which. drum 8 extends longitudinally of the launching barge on one end thereof. A longitudinally extending well 9 is also provided in the launching barge for a purpose which will hereinafter appear. l
The revetment mat sections 4 are unrolled from the stand 'I and rolled up on the large drum 8, with the unit sections being joined together by threading small cables I0 through the exposed loops I I on the ends of the unit sections thus forming a revetment mat of a predetermined length. Before the first unit section is rolled up on the drum 8 on the stand 'I' on the launching barge 2, heavy anchor weights I2 are attached to the starting end thereof, which weights I2 iit into a longitudinally extending recess I3 formed on the drum. With the revetment mat rolled around the drum 8 the anchor weights I2 are held in the recess I3 of the drum.
After sufficient unit sections are joined together to form a complete revetment mat of desired length the rolled-up mat and drum 8 are removed from the stand l by the derrick 5 and placed on the river bank as shown by the dotted lines at A or may be placed in the water through the well 9 in the launching barge 2 as shown at B. A rear spreader bar I4 and a frame structure I5 are connected to the drum 8, said frame structure I5 including an inclosed portion I6 having side bars Il, a front member I8 and a rear cross bar I9, with arms 2U extending rearwardly from the ends of the cross bar I9 and connected to the ends of the axle of the drum 8. The rear spreader bar I4 may be connected to the aXle of the drum by cables 2I or any other suitable means and has a rehaul cable 22 attached to it, while one end of a pulling cable 23 is attached to the front member I8 of the frame structure. The rehaul cable 22 leads from a power winch 24 on the mooring barge to a pulley block 25 on the shore and from there to the rear spreader bar I4.
Before the revetment mat is unrolled, the anchor cables attached to the head of the mat are fastened to anchors 26 on shore, after which it is pulled down the slope of the river bank by means of the pulling cable 23 leading to a power winch 2'I mounted on an anchor` barge 28 in mid-stream. After the mat has been unrolled down the slope of the river bank and the drum 8 has been released, the drum is pulled back up the slope of the river bank over the revetment mat just laid, by means of the rehaul cable 22 attachedat,Y one end to the rear spreader bar I4 andleading tothe power winch 24 on the mooring bargev I. The drum 8 is then picked up at the waters edge by the derrick 5 on the mo-oring barge I and is placed on the stand 'I' for forming another complete revetment mat from unit mat sections. If desired under some conditions the revetment mat may be unrolled by gravityV down the slope of the river bankV without the use of the anchor barge 2S.
,In Fig. 2 the revetment mat is shown being unrolled down the slope of the river bank in diiferent positions coming to rest finally at the bottom Vof the slope of the river bank, with the heavy weights I2 on the bottom end of the revetment mat serving as anchors to hold down the lower end of the mat, thus preventing the river current from turning back the end of the mat.
After one mat is unrolled, the entire operation is repeated, with each succeeding mat overlapping the mat previously laid. The mats will be unroled from the waters edge down the slope of the river bank andthe work will progress upstream as each mat is laid until a completed revetment covering the desired area is completed.
The mats may be lapped over each other any amount to take care of a severe lor light attack of the water against the river bank. By this method of laying the mats, a laminated type of construction is provided and a series of slip joints is also provided between the mats to take care of settlements in the graded bank and still provide proper protection.
Wherever the term launching cable is used in the appended claims the term refers to the cable system comprising the rehaul cable 22 and the pulll cable 23.*7 The term yoke refers to the composite structure on which the roll-type mat and core is mounted for laying'. The yoke is the structure performing the function of interconnecting rehaul cable 22 and pull cable 23.
It will thus be seen that there is herein provided a novel and efcient form of apparatus for launching revetment mats which is well adapted for the purpose intended. Even though there has been herein shown certain features of construction and operation of parts, it is nevertheless to be understood that various changes may be made therein without departing from the spirit or scope of the claims.
Having thus described my invention, what I claim as new and wish to secure by Letters Patent is:
1.71A method of protecting river banks against erosion which comprises anchoring a series of mat being controlled by applying continuouslyr to each mat oppositely directed straight line revetment mats at contiguous anchoring stations, positioning succeeding mats in edge-overlapping relation relative to one another for unrolling down a river bank to be protected, each mat being rolled into a roll or coilvhaving an exposed head end and a foot end enclosed in the roll, the head end of each mat being anchored at the respective anchoring stations, unrolling the succeeding mats while controlling the unrolling so that each mat as unrolled definitely follows a predetermined path, so that adjacent edges ofthe succeeding mats overlap, whereby when unrolled, one mat will lap over the adjacent mat along adjacent edges until a complete revetment is formed, the resulting revetment construction thus being provided with a series of overlapping edges forming a series of slip joints for taking care of settlements in the sloped river bank and at the same time providing proper protection to the bank, the unrolling of each pulls from a source remote from the anchoring station for the mat, the straight line unrolling pull exceeding in force the oppositely directed pull, the said straight line pulls however cooperat- Y ing to control and to maintain the mats definitely in the predetermined path during unrolling thereof, and automatically anchoring the `foot end of each mat in laid position responsivelyto complete unrolling of the mat with attendant" release of the foot end of the mat.
