Description

Technical Field

[0001] This utility model belongs to the field of water-stopping and seepage prevention repair technology, and in particular relates to a continuous laying device for a water-stopping structure of a joint on a sloping surface with large water depth. Background Technology

[0002] With continuous technological advancements, and to meet the needs of national and urban development, the construction depth of water-related structures in water conservancy projects has reached hundreds of meters. Statistics show that my country has over 164 dams exceeding 100 meters in depth, such as the Baihetan Hydropower Station, a newly completed national strategic project, which has a submerged depth of 280 meters after impoundment. The construction depth of underwater structures involving the ocean, especially in deep-sea areas, can reach hundreds to thousands of meters. As the service life of reservoirs, dams, ports, and coastal seepage prevention structures increases, more and more leakage problems are becoming apparent. The main reasons are the aging of the sealing materials at the joints and the settlement and tension of the original foundation during construction, leading to water seepage at the joints. Leakage, especially under high water head conditions, poses a significant safety hazard to the structures, thus requiring timely underwater inspections and seepage prevention repairs during operation.

[0003] Currently, the repair method for underwater seepage prevention structures involves replacing the original failed water-stopping modules underwater. Following diving operation decompression standards, repairs at depths shallower than 60 meters can be performed manually using pipe-supplied air diving, making the operation relatively controllable in terms of cost, efficiency, and safety risks. However, at depths greater than 60 meters, divers must use mixed or saturated air diving for repair work. The cost of air sources and equipment for mixed and saturated air diving increases dramatically, and the risks and efficiency of divers working at greater depths are also higher.

[0004] This utility model designs a continuous laying device for a water-stopping structure on a sloping surface with deep water to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A continuous laying device for joint waterproofing structure on a sloping surface with great water depth, comprising:

[0007] The trolley system includes a trolley frame, camera and lighting equipment, a trolley central controller, a washer, a driver, a moving device, and a suction machine. The trolley frame, camera and lighting equipment, and trolley central controller are installed on the upper part of the trolley frame, with the camera and lighting equipment facing the front end of the trolley frame. The washer is installed at the front end of the trolley frame, and the driver is installed at the rear end of the trolley frame. The moving device and suction machine are installed at the bottom of the trolley frame. An arc-shaped molding groove is provided at the lower end of the trolley frame. Several rollers are installed on the inner wall of the molding groove, and the roller axes are parallel to the tangent of the inner wall of the molding groove.

[0008] The material car system includes a material car platform, a float distribution device, a material car central controller, and a material car driver. The float distribution device, the material car central controller, and the material car driver are all installed at the lower end of the material car platform. The upper end of the material car platform is provided with several through holes arranged in the front-back direction. Several push rollers are installed inside the material car platform. The push rollers are spindle-shaped with a diameter in the middle section larger than the diameter at both ends. The edge of the middle section of the push roller protrudes from the through hole to the outside of the material car platform.

[0009] As a preferred embodiment, the mobile device includes four wheels, which are mounted at the bottom of the four corners of the trolley frame, and steering gears are installed on the wheels.

[0010] As a preferred embodiment, the trolley central controller is electrically connected to the steering gear, flushing device, suction machine, drive unit, and camera and lighting equipment, respectively.

[0011] As a preferred option, the camera lighting equipment includes an underwater camera and an underwater light.

[0012] As a preferred embodiment, the central controller of the material cart is electrically connected to the float distribution device, the material cart driver, and the push roller, respectively.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] 1. This utility model utilizes a trolley system and a material cart system to continuously lay materials along a predetermined location while feeding them, which effectively improves the efficiency of underwater construction. The suction force generated by the suction machine can make the trolley adhere to the slope surface and move. It can achieve continuous laying of the water-stop module on the slope surface under deep water conditions. The whole process does not require the operation of divers, which greatly reduces the safety risks of underwater operations under deep water conditions.

[0015] 3. The trolley system of this utility model can remove the accumulated debris in front of the travel route through the flushing device, so as to provide a clean base surface for the laying of the water-stop module. In addition, the shaping groove can shape the upper part of the water-stop module to a certain extent and lay it at the joint. The roller reduces the friction between the water-stop module and the shaping groove, so that the trolley frame can move normally. The on-board camera and lighting equipment can observe the travel route in real time underwater, and make timely route adjustments if deviation occurs.

[0016] 4. The material cart system of this utility model slowly pushes the water-stop module out of the material cart platform by pushing rollers, reducing the friction of the material feeding action during the laying of the water-stop module. The equipped float can be adjusted according to the weight carried by the material cart platform to meet the needs of underwater material feeding. Attached Figure Description

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following embodiments or drawings are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0025] A continuous laying device for water-stopping structure at joints on steep slopes with large water depth, such as... Figures 1 to 4 As shown, the system includes: a trolley system 100, which includes a trolley frame 101, a camera and lighting device 102, a trolley central controller 103, a washer 104, a driver 105, a moving device 106, and a suction machine 107. The trolley frame 101, the camera and lighting device 102, and the trolley central controller 103 are installed on the upper end of the trolley frame 101, with the camera and lighting device 102 facing the front end of the trolley frame 101. The washer 104 is installed on the front end of the trolley frame 101, the driver 105 is installed on the rear end of the trolley frame 101, and the moving device 106 and the suction machine 107 are installed on the bottom of the trolley frame 101. An arc-shaped molding groove 108 is provided at the lower end of the trolley frame 101. Several rollers 109 are installed on the inner wall of the molding groove 108, and the axis of the rollers 109 is parallel to the tangent of the inner wall of the molding groove 108.

[0026] The material cart system 200 includes a material cart platform 201, a float distribution device 202, a material cart central controller 203, and a material cart driver 204. The float distribution device 202, the material cart central controller 203, and the material cart driver 204 are all installed at the lower end of the material cart platform 201. The upper end of the material cart platform 201 is provided with several through holes 205 arranged in the front-back direction. Several push rollers 206 are installed inside the material cart platform 201. The push rollers 206 are spindle-shaped with a middle diameter larger than the diameters at both ends. The middle edge of the push rollers 206 protrudes from the through holes 205 to the outside of the material cart platform 201.

[0027] The application of underwater machinery and equipment to the laying of dam water-stop modules during the operational phase, utilizing the trolley system 100 and the material cart system 200 to continuously lay materials along predetermined locations while simultaneously feeding them, effectively improves underwater construction efficiency, reduces the safety risks for divers operating at great depths, and enhances the construction efficiency and quality of joint water-stop modules. This method enables the continuous laying and forming of joint water-stop modules during the operational phase of completed dams, promoting the application efficiency of joint water-stop modules at great depths, improving construction quality, and popularizing the seepage prevention technology of completed panel dams.

[0028] The trolley system 100 can remove accumulated debris in front of the travel route through the flusher 104, providing a clean base for the water-stop module 300. In addition, the shaping groove 108 can shape the upper part of the water-stop module 300 to a certain extent and lay it at the joint. The roller 109 reduces the friction between the water-stop module 300 and the shaping groove 108, allowing the trolley frame 101 to move normally. The onboard camera and lighting equipment 102 can observe the travel route in real time underwater and make timely route adjustments if deviation occurs.

[0029] The material cart system 200 slowly pushes the water-stop module 300 out of the material cart platform 201 by pushing roller 206, reducing the friction of the material feeding action during the laying of the water-stop module 300. The equipped float 202 can adjust according to the weight carried by the material cart platform 201 to meet the needs of underwater material feeding.

[0030] like Figure 2 and Figure 3 As shown, the mobile device 106 includes four wheels 110, which are mounted on the bottom of the four corners of the trolley frame 101. Steering devices 111 are mounted on the wheels 110. The camera and lighting equipment 102 includes an underwater camera 112 and an underwater light 113.

[0031] The trolley central controller 103 is electrically connected to the steering device 111, the flusher 104, the suction machine 107, the driver 105, and the camera and lighting equipment 102, respectively. The material cart central controller 203 is electrically connected to the floater 202, the material cart driver 204, and the push roller 206, respectively.

[0032] Construction method:

[0033] Step 1:

[0034] The trolley system 100 enters the water along the building slope. The camera and lighting equipment 102 identifies the location of the slope joint. By controlling the drive 105 and the moving device 106, the central axis of the plastic groove 108 under the trolley frame 101 is made to coincide with the center of the joint.

[0035] Step 2:

[0036] The suction machine 107 is turned on by the central controller 103 of the trolley. The trolley system 100 adheres to the slope surface by the suction of the suction machine 107. The flushing machine 104 is started to clear the silt and debris in front of the trolley system 100 to the outside, so as not to affect the movement of the trolley and the laying of the water-stopping module 300.

[0037] Step 3:

[0038] The water-stop module 300 is placed on the material cart platform 201, and the water-stop module 300 contacts the protruding part in the middle of the push roller 206. The material cart system 200 is placed in the water, and the operation of the float distribution device 202 is adjusted by the material cart central controller 203, so that the material cart system 200 carries the water-stop module 300 to the front of the trolley system 100 and makes the water-stop module 300 coincide with the central axis of the shaping groove 108.

[0039] Step 4:

[0040] Start the push roller 206. The push roller 206 pushes the water-stop module 300 toward the trolley system 100 by friction, so that the head of the water-stop module 300 contacts the shaping groove 108.

[0041] Step 5:

[0042] The control trolley system 100 and the material trolley system 200 move forward along the joint. The material trolley system 200 continuously pushes the water-stop module 300. The head of the water-stop module 300 is inserted into the shaping groove 108. The inner wall of the shaping groove 108 squeezes the water-stop module 300. The roller 109 contacts the water-stop module 300, so that the water-stop module 300 fits into the joint under the squeezing of the shaping groove 108, and the water-stop module 300 is laid at the joint.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
