Technical Field

[0001] This application relates to the field of diversion cofferdam technology, and in particular to a diversion cofferdam for a cross-river aqueduct. Background Technology

[0002] An aqueduct is an elevated water channel spanning rivers, canals, roads, and valleys. Currently, the aqueduct body, supporting columns, and other components are mostly constructed using prefabrication and hoisting techniques, while the aqueduct foundations generally employ large-scale gravity foundations. Sufficient space is required for the construction of prefabricated hoisting systems and large-scale gravity foundations.

[0003] Existing diversion cofferdams, being prefabricated, require transportation, hoisting, and installation at the site of use. However, large equipment such as cranes and transport vehicles are not readily available at some locations, which affects the convenience and efficiency of installation. Therefore, this application proposes a cross-river aqueduct diversion cofferdam to solve the aforementioned technical problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a cross-river aqueduct diversion cofferdam, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0006] In a preferred embodiment, the bottom of the bracket has two symmetrically arranged insertion holes, and the two pins are adapted to be inserted into the inner walls of the two insertion holes.

[0007] By adopting the above technical solution, the side plate can be positioned to ensure its stability when installed on the inner wall of the two inner baffles, and to prevent it from easily tipping over.

[0008] In a preferred embodiment, the middle part of the stud is inserted into the inner wall of the side plate, and two nuts are threaded on the outer edge of the stud, with the outer edges of the two nuts abutting against the outer wall of the bracket.

[0009] By adopting the above technical solution, it is possible to connect the two brackets, the inner baffle, and the side plate, thereby further ensuring the stability of the side plate away from the pin.

[0010] In a preferred embodiment, a fixing plate is fixedly installed at the bottom of the bracket, and two pins are inserted into the inner wall of the fixing plate.

[0011] By adopting the above technical solution, when the device is installed at the site of use, the pins can be stably inserted into the soil, ensuring that the bracket and inner baffle can be installed vertically on the ground, preventing it from tipping over and improving stability.

[0012] In a preferred embodiment, the inner wall of the bracket is provided with a positioning groove, and the crossbar is inserted into the inner wall of the positioning groove.

[0013] By adopting the above technical solution, the horizontal bar can tightly connect multiple supports together to form a frame, ensuring stability.

[0014] In a preferred embodiment, there are two side plates, which are symmetrically arranged on both sides of the sandbag. The side plates, bottom plate, and outer baffle are all made of galvanized steel plate.

[0015] By adopting the above technical solutions, the side panels, bottom panels and outer baffles will not be easily corroded after being washed by rainwater and soil, thus improving their durability.

[0016] The beneficial effects of this application are:

[0017] This type of cross-river aqueduct diversion cofferdam facilitates on-site assembly of the diversion structure by setting up supports, insertion holes, outer baffles, bottom plates, and sandbags, thus eliminating the need for large crane operations, ensuring applicability, and improving the convenience and efficiency of assembly. At the same time, the sandbags and supports can be transported separately, improving the convenience of transportation.

[0018] This type of cross-river aqueduct diversion cofferdam can locate the position of the two outer baffles by inserting studs into the inner walls of the support, inner baffles and side plates, and threading nuts onto the outer edge of the studs. At the same time, it can further locate the side plates to ensure stability. Attached Figure Description

Guide grooves 3 are opened on the inner side of the inner baffles 2. Side plates 5 are slidably inserted into the inner wall of the guide grooves 3. Two pins 6 are symmetrically fixedly installed at the bottom of the side plates 5. Studs 7 are inserted into the inner walls of the supports 1 and the inner baffles 2. Horizontal bars 9 are inserted into the inner wall of the supports 1. A bottom plate 10 is installed at the inner bottom of the supports 1. Outer baffles 11 are inserted into the inner walls of the supports 1 and the inner baffles 2. Sandbags 12 are filled and installed in the inner cavity of the supports 1.

[0026] See Figure 4 The bottom of the bracket 1 has two symmetrical holes 4, and two pins 6 are adapted to be inserted into the inner wall of the two holes 4, so that the side plate 5 can be positioned to ensure the stability of the side plate 5 when it is installed on the inner wall of the two inner baffles 2, and to ensure that it will not easily tip over.

[0027] See Figure 4 The middle part of the stud 7 is inserted into the inner wall of the side plate 5. Two nuts 8 are threaded on the outer edge of the stud 7, and the outer edges of the two nuts 8 abut against the outer wall of the bracket 1, so that the two brackets 1, the inner stop strip 2 and the side plate 5 can be connected together, further ensuring the stability of the side plate 5 away from the pin 6.

[0028] See Figure 1 A fixing plate 13 is fixedly installed at the bottom of the bracket 1. Two pins 14 are inserted into the inner wall of the fixing plate 13, so that when the device is installed at the place of use, the pins 14 can be stably inserted into the soil, ensuring that the bracket 1 and the inner baffle 2 can be installed vertically on the ground, preventing them from tipping over and improving stability.

[0029] See Figure 4 The inner wall of the bracket 1 is provided with a positioning groove, and the horizontal bar 9 is inserted into the inner wall of the positioning groove, so that the horizontal bar 9 can tightly connect multiple brackets 1 together to form a frame and ensure stability.

[0030] See Figure 1 - Figure 4There are two side plates 5, and the two side plates 5 are symmetrically arranged on both sides of the sandbag 12.
