Description

Technical Field

[0001] This application relates to the technical field of concrete conduit pouring, and particularly relates to a conduit for underwater concrete pouring. Background Art

[0002] Underwater cast-in-place concrete is also known as conduit concrete, which is a method of pouring concrete through a vertical pipe relying on the self-weight of the concrete; it is applicable to underwater or underground projects such as cofferdams, caisson foundations, open caisson foundations, diaphragm walls, and pile foundations; in order to meet the requirements of ultra-deep conduit concrete pouring, it is usually necessary to connect and extend the vertical pouring pipe to meet the pouring requirements.

[0003] After retrieval, a patent with the authorized announcement number of CN221095139U in China discloses a conduit device for underwater concrete pouring of large-diameter deep foundation piles, including a conduit main body, a connection sleeve, and a bolt group. The conduit main body includes a conduit pipe body, and a conduit flange is fixedly installed on the surface of the conduit pipe body.

[0004] The above-mentioned conduit device for underwater concrete pouring of large-diameter deep foundation piles has the following deficiencies: Although this device uses both flange plates and threaded connections, the connection is firm and the connection inspection is convenient and simple. However, when installing two conduits, it is often necessary to rotate the conduit to fix the connection. Since the conduits for underwater concrete pouring are relatively long and heavy, the rotation installation is rather troublesome. Moreover, this device also requires tools to tighten multiple bolts for connection and fixation during the connection process, resulting in a relatively long installation time and thus affecting the progress of concrete conduit pouring. Summary of the Utility Model

[0005] The purpose of the present utility model is to solve or at least alleviate the problem in the prior art that tools are still required to tighten multiple bolts for connection and fixation during the connection process, resulting in a relatively long installation time and thus affecting the progress of concrete conduit pouring.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A conduit for underwater concrete pouring, including a first pipe body and a second pipe body. The ends of the first pipe body and the second pipe body close to each other are respectively fixedly sleeved with a first installation box and a second installation box. An installation mechanism for connecting and fixing the first pipe body and the second pipe body is provided in the first installation box.

[0007] The installation mechanism includes two mounting plates slidably mounted on the inner wall of one side of the first mounting box. Threaded blocks are fixedly mounted on the outer walls of one sides of the two mounting plates. The same screw rod is screwed on the two threaded blocks, and the screw rod is a bidirectional screw rod. One end of the screw rod is fixedly mounted with a rotating column. One end of the rotating column penetrates through the outer wall of one side of the first mounting box and is fixedly mounted with a knob. A connecting plate is fixedly mounted on the inner wall of the top of the second mounting box, and the connecting plate is located inside the first mounting box.

[0008] With the above technical solution, by rotating the knob, the rotation of the knob will drive the rotation of the rotating column and the screw rod. The rotation of the screw rod will drive the two threaded blocks and the two mounting plates to approach each other. The mutual approach of the two mounting plates can clamp and fix the connecting plate, and further can install and fix the first pipe body and the second pipe body. There is no need to rotate the first pipe body or the second pipe body, reducing the manual labor force, and it is also convenient for quick disassembly, improving the progress of concrete conduit pouring.

[0009] Optionally, two limiting grooves are symmetrically formed on the inner wall of one side of the first mounting box. Limiting blocks are slidably mounted in the two limiting grooves, and the two limiting blocks are fixedly connected to the corresponding mounting plates.

[0010] With the above technical solution, the limiting movement of the mounting plate can be achieved by providing the limiting grooves and the limiting blocks.

[0011] Optionally, fixing grooves are formed on the outer walls of both sides of the connecting plate. Fixing blocks are slidably mounted in the two fixing grooves, and the two fixing blocks are fixedly connected to the corresponding mounting plates.

[0012] With the above technical solution, the installation and fixing effect of the mounting plate can be enhanced by providing the fixing grooves and the fixing blocks.

[0013] Optionally, a first fixing ring and a second fixing ring are respectively fixedly mounted on the inner walls of the first mounting box and the second mounting box close to each other. The first fixing ring and the second fixing ring are respectively fixedly sleeved on the corresponding first fixing ring and second fixing ring.

[0014] With the above technical solution, the role of auxiliary installation can be played by providing the first fixing ring and the second fixing ring.

[0015] Optionally, positioning blocks are fixedly mounted on the outer surfaces of both sides of the first fixing ring. Card slots are formed on the outer walls of the bottoms of the two positioning blocks. Clamping blocks are slidably mounted in the two card slots, and the two clamping blocks are respectively fixedly mounted on the outer surfaces of both sides of the second fixing ring.

[0016] With the above technical solution, the positioning installation of the first fixing ring and the second fixing ring can be achieved by providing the card slots and the clamping blocks.

[0017] Optionally, a protective box is fixedly installed on an outer wall of one side of the first installation box, and a box door is hinged to one side of the protective box.

[0018] By adopting the above technical solution, the protective box can play a protective role.

[0019] Optionally, a telescopic rod is fixedly installed on an inner wall of the top of the protective box, a telescopic spring is sleeved on the telescopic rod, a bottom end of the telescopic rod is fixedly connected with a rectangular plate, and an abutting plate is fixedly installed on an outer wall of the bottom of the rectangular plate.

[0020] By adopting the above technical solution, by pulling the abutting plate upward, the abutting plate moves upward, so that the abutting and fixing of the knob can be released.

[0021] Optionally, the abutting plate is arc-shaped and is arranged in a fitting manner with the knob.

[0022] By adopting the above technical solution, by arranging the abutting plate in an arc shape, the knob can be fitted and limited.

[0023] In summary, the beneficial effects of the present application are as follows:

In the present application, with the cooperation of a connecting plate and the like, by rotating the knob, the rotation of the knob will drive the rotating column and the screw rod to rotate. The rotation of the screw rod will drive the two threaded blocks and the two mounting plates to approach each other. The two mounting plates approaching each other can clamp and fix the connecting plate, and further can install and fix the first pipe body and the second pipe body. There is no need to rotate the first pipe body or the second pipe body, reducing the manual labor force, and it is also convenient to quickly disassemble it, improving the progress of concrete conduit pouring.

[0025] 2. In the present application, with the cooperation of an abutting plate and the like, by splicing the first pipe body and the second pipe body together, at this time, the connecting plate on the second installation box is located in the first installation box. Then, the box door can be opened and the abutting plate can be pulled upward. The upward movement of the abutting plate can release the abutting and fixing of the knob, and can also limit the rotation of the knob. BRIEF DESCRIPTION OF THE DRAWINGS

By arranging the knob 18, an auxiliary driving effect can be achieved. A connecting plate 21 is fixedly installed on the top inner wall of the second mounting box 4. The connecting plate 21 is located in the first mounting box 3.

[0035] During use, by rotating the knob 18, the rotation of the knob 18 will drive the rotating column 17 and the screw rod 16 to rotate. The rotation of the screw rod 16 will drive the two threaded blocks 15 and the two mounting plates 14 to approach each other. The mutual approach of the two mounting plates 14 can clamp and fix the connecting plate 21, and further can install and fix the first pipe body 1 and the second pipe body 2, without rotating the first pipe body 1 or the second pipe body 2, reducing the manual labor force, and also facilitating its quick disassembly, improving the progress of concrete conduit pouring.

[0036] Refer to Figure 3, on one side inner wall of the first installation box 3, two limiting grooves 12 are symmetrically opened. Two limiting blocks 13 are slidably installed in the two limiting grooves 12, and the two limiting blocks 13 are fixedly connected to the corresponding mounting plates 14. By providing the limiting grooves 12 and the limiting blocks 13, the limiting movement of the mounting plate 14 can be achieved.

[0037] Refer to Figure 3 , on the outer walls of both sides of the connecting plate 21, fixing grooves 19 are opened. Two fixing blocks 20 are slidably installed in the two fixing grooves 19, and the two fixing blocks 20 are fixedly connected to the corresponding mounting plates 14. By providing the fixing grooves 19 and the fixing blocks 20, the installation and fixing effect of the mounting plate 14 can be enhanced.

At this time, the connecting plate 21 on the second mounting box 4 is located inside the first mounting box 3. Then, the box door 6 can be opened and the abutting plate 25 can be pulled upward to move. The upward movement of the abutting plate 25 can release the abutting fixation of the knob 18.

[0044] At this time, the knob 18 can be rotated. The rotation of the knob 18 will drive the rotating column 17 and the screw rod 16 to rotate. The rotation of the screw rod 16 will drive the two threaded blocks 15 and the two mounting plates 14 to approach each other. The mutual approach of the two mounting plates 14 can clamp and fix the connecting plate 21, and further can install and fix the first pipe body 1 and the second pipe body 2. There is no need to rotate the first pipe body 1 or the second pipe body 2, which reduces the manual labor and is also convenient for quick disassembly, improving the progress of concrete conduit pouring.
