Technical Field
[0001] This application relates to the technical field of water conservancy projects, and particularly to a reinforcement and heightening structure for a grouted rubble retaining wall of a river channel. Background Art
[0002] River regulation is an engineering measure that follows the law of river evolution, guides the river according to its trend, adjusts and stabilizes the position of the main river course, improves the flow, sediment movement, and the scouring and silting parts of the river bed to meet the requirements of national economic construction such as flood control, shipping, water supply, and drainage. River regulation includes controlling and adjusting the river regime, cutting off meanders, widening the river channel, and dredging, etc.
[0003] At present, the revetments of many river channels adopt grouted rubble retaining walls. During the process of river regulation, they generally will not be demolished because the demolition workload is large and the construction period is long. Therefore, it is necessary to reinforce and heighten them on this basis to turn them into new river bank structures. To solve the problems of reinforcement and heightening of grouted rubble retaining walls, our company has specifically designed a reinforcement and heightening structure for grouted rubble retaining walls of river channels.

A reinforcement and heightening structure is arranged beside the revetment. The reinforcement and heightening structure includes a bearing member, a connecting wall, and a facing wall. The bearing member is a precast pile, and a plurality of them are provided. The plurality of bearing members are evenly rammed into the bearing stratum. The connecting wall is cast on the plurality of bearing members, and a first anchor bar is connected between the connecting wall and the revetment. The facing wall is cast on the top of the connecting wall and is communicated with the connecting wall. A second anchor bar is connected between the facing wall and the revetment;
[0007] The top of the facing wall has a raised section that extends out of the revetment. A transverse plate is integrally cast on the side of the raised section. A third anchor bar is connected between the transverse plate and the revetment. A drain pipe is inclinedly arranged in the raised section;
[0008] The connecting wall and the facing wall are designed for segmented casting, and a water stop belt is arranged between adjacent connecting walls and adjacent facing walls.
[0009] Preferably, it further includes an anchor block. The anchor block is arranged in the dam beside the revetment. A pull rod is connected between the anchor block and the raised section. Both ends of the pull rod have hook parts.
[0010] By adopting the above technical solution, by providing an anchoring block and a tie rod, the tie rod is used to anchor the concrete facing wall to limit the forward tilt of the facing wall.
[0011] Preferably, in order to avoid water leakage at the joint, the waterstop is a rubber waterstop. The two ends of the waterstop are respectively cast into the wall body, and a polyethylene foam board is also filled in the gap between the adjacent connecting wall and the adjacent facing wall.
[0012] Preferably, a catch well is arranged on one side of the drain pipe away from the raised section, and a filter screen is arranged inside the catch well.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The following will further describe the present application in detail Figure 1-2 with reference to the attached drawings.
[0019] An embodiment of the present application discloses a reinforcement and heightening structure for a river channel rubble masonry retaining wall. Refer to Figure 1-2, including a revetment 1, with a reinforcement and heightening structure arranged beside the revetment 1. The reinforcement and heightening structure includes a bearing member 2, a connecting wall 3, and a facing wall 4. The bearing member 2 is a precast pile, and multiple bearing members 2 are provided. The multiple bearing members 2 are evenly rammed into the bearing stratum. The connecting wall 3 is poured on the multiple bearing members 2, and a first anchor bar 31 is connected between the connecting wall 3 and the revetment 1. The facing wall 4 is poured on the top of the connecting wall 3 and is communicated with the connecting wall 3. A second anchor bar 41 is connected between the facing wall 4 and the revetment 1;
[0020] The top of the facing wall 4 has a raised section 42 extending out of the revetment 1. A transverse plate 43 is integrally poured on the side of the raised section 42. A third anchor bar 44 is connected between the transverse plate 43 and the revetment 1. A drain pipe 5 is inclinedly arranged in the raised section 42;

A tie rod 9 is connected between the anchor block 8 and the raised section 42. Both ends of the tie rod 9 have hook parts, and the hook parts can facilitate connection with the steel cage framework.
[0023] By arranging the anchor block 8 and the tie rod 9, the concrete facing wall 4 is anchored by the tie rod 9 to limit the forward tilt of the facing wall 4.
[0024] In order to avoid blocking the drain pipe 5, a catch well 10 is arranged on the side of the drain pipe 5 away from the raised section 42. A filter screen is arranged inside the catch well 10, and the staff can clean the filter screen regularly.
[0025] The implementation principle of a reinforcement and heightening structure for a river channel mortar rubble retaining wall in an embodiment of this application is as follows:
[0026] Use pile driving equipment such as a water excavator to ram several precast piles side by side into the bearing stratum beside the existing revetment 1. Then, roll the steel cages of the connecting wall 3 and the facing wall 4 on the basis of the precast piles, and connect them to the existing revetment 1 through the first anchor bar 31, the second anchor bar 41, and the third anchor bar 44 respectively. Then, first pour underwater concrete to form an underwater connecting wall 3 to bear the vertical load of the vertical facing wall 4, and then pour above-water concrete to form the facing wall 4, so as to cooperate with the original revetment 1 to form a new retaining wall, with low manufacturing cost and short construction period.
[0027] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
