Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cofferdams, and particularly relates to an integrated steel cofferdam for crossing a culvert box. Background Art
[0002] With the increasing emphasis on environmental governance by the state, the construction and improvement of urban sewage pipe networks have become an important part of urban infrastructure construction. The construction of sewage pipe networks is not only related to the improvement of the urban environment but also the key to ensuring the quality of citizens' lives. However, in urban areas, due to the large flow of people and dense surrounding buildings, traditional sewage pipe network construction methods face many challenges.
[0003] As an important part of the urban drainage system, the structural characteristics and the surrounding environment of urban culvert boxes pose higher requirements for construction methods. Existing construction methods, such as building earth cofferdams for sectional diversion, often require large construction equipment and sufficient working space. On urban roads, it is difficult to meet these conditions, resulting in slow construction progress. Moreover, due to multiple interruptions during the construction process, the construction quality of the joint parts is likely to be poor, affecting the construction quality and increasing the difficulty and cost of later maintenance. Content of the Utility Model
[0004] In order to improve construction efficiency and construction quality, the present application provides an integrated steel cofferdam for crossing a culvert box.
[0005] In order to achieve the above object, the present application adopts the following technical solutions:
[0006] An integrated steel cofferdam for crossing a culvert box includes a steel cofferdam structure arranged in the culvert box. The steel cofferdam structure includes a water retaining plate, a support assembly, and a diversion pipe. There are two groups of the water retaining plates, which are respectively arranged on the upstream side and the downstream side of the culvert box. The support assembly penetrates through the two groups of water retaining plates and is fixedly connected to the water retaining plates. The diversion pipe is arranged through between the two groups of water retaining plates.
[0007] By adopting the above device, since the steel cofferdam structure is prefabricated in advance and only hoisting is required on site, the construction period is greatly shortened, and the safety risk during the construction process is reduced. The support assembly penetrates through and fixedly connects the two groups of water retaining plates, enhancing the overall stability of the cofferdam structure and ensuring safety during the construction process. The diversion pipe is arranged between the two groups of water retaining plates to effectively divert the water flow in the culvert box, avoid the interference of the water flow in the construction area, and ensure a dry construction environment. The integrated cofferdam of the present application can not only conduct full-section diversion at one time, but also is convenient to install, has a fast construction speed, effectively reduces the safety hazards during the construction process, ensures the construction quality of the entire section of the pipe network, effectively improves the construction efficiency, and reduces the maintenance cost.
[0008] As a further description of the above technical solution:
[0009] Each set of the water baffle includes two steel plates arranged in parallel, and the thickness of the steel plates is greater than that of the diversion pipe.
[0010] By adopting the above device, each set of water baffles is composed of two steel plates arranged in parallel, providing stronger water blocking performance, and the thicker steel plates increase the overall structural strength, enabling the water baffle to withstand greater water pressure, thus remaining stable during the construction process. At the same time, the increase in the thickness of the steel plates improves its durability and can resist the impact of water flow for a long time and the damage of external environmental factors.
[0011] As a further description of the above technical solution:
[0012] The length of the steel plate is consistent with the width of the box culvert.
[0013] By adopting the above device, the consistency of the length of the steel plate and the width of the box culvert ensures that the water baffle can completely cover the entire cross-section of the box culvert, forming a complete sealing barrier, achieving a match with the size of the box culvert, effectively preventing water from overflowing from the side, and ensuring the dryness of the construction area.
[0014] As a further description of the above technical solution:
[0015] A plurality of support seats are arranged at the bottom of the diversion pipe.
[0016] By adopting the above device, the plurality of support seats are evenly distributed, which can effectively disperse the weight of the diversion pipe, enhance the stability of the diversion pipe in the cofferdam, and reduce the influence on the diversion pipe caused by uneven settlement of the ground.
[0017] As a further description of the above technical solution:
[0018] A seal is arranged at the end of the water baffle, and the seal is used to enhance the sealing performance of the entire steel cofferdam structure.
[0019] By adopting the above device, the design of the seal at the end of the water baffle effectively prevents water from leaking through the gap at the end of the water baffle, enhances the sealing performance of the entire steel cofferdam structure, keeps the construction area dry, and provides a good environment for construction operations.
[0020] As a further description of the above technical solution:
[0021] The support assembly includes a plurality of support bars, and the plurality of support bars are perpendicular to the steel plate and parallel to the diversion pipe, and the support bars are welded to the steel plate.
[0022] By adopting the above device, the vertical welded connection between the support bars and the steel plates increases the rigidity of the entire cofferdam structure, provides stable support for the entire cofferdam structure, significantly enhances the structural stability, and enables it to withstand greater water flow pressure and mechanical stress during the construction process.
[0023] As a further description of the above technical solution:
[0024] A plurality of lifting holes are provided near the top of the steel plate for lifting the entire steel cofferdam structure.
[0025] By adopting the above device, the design of the lifting holes enables the entire steel cofferdam structure to be easily lifted by a hoisting machine, quickly placing the cofferdam structure in place, simplifying the transportation and installation process, significantly improving the construction efficiency and shortening the construction period.
[0026] As a further description of the above technical solution:
[0027] A plurality of reinforcing ribs are provided between the two parallel steel plates, and the ends of the reinforcing ribs are fixedly connected to the steel plates.
[0028] By adopting the above device, the fixed connection between the reinforcing ribs and the steel plates significantly improves the local and overall strength of the cofferdam structure, enables it to withstand greater water pressure and other external forces, and reduces deformation caused by water flow impact or uneven stress.
[0029] The present application has the following beneficial effects:
[0030] 1. In the present application, since the steel cofferdam structure is prefabricated in advance and only needs to be lifted on site, the construction period is greatly shortened and the safety risk during the construction process is reduced. The support components penetrate and fixedly connect the two groups of water retaining plates, enhancing the overall stability of the cofferdam structure and ensuring safety during the construction process. The diversion pipe is arranged between the two groups of water retaining plates to effectively divert the water flow in the culvert, avoid water flow interference in the construction area, and ensure a dry construction environment. The integrated cofferdam of the present application can not only conduct diversion for the entire section at one time, but also is convenient to install, has a fast construction speed, effectively reduces the potential safety hazards during the construction process, ensures the construction quality of the entire section of the pipe network, effectively improves the construction efficiency, and reduces the maintenance cost.
[0031] 2. In the present application, the vertical welded connection between the support bars and the steel plates increases the rigidity of the entire cofferdam structure, provides stable support for the entire cofferdam structure, significantly enhances the structural stability, and enables it to withstand greater water flow pressure and mechanical stress during the construction process.

[0037] The following further elaborates on this application in conjunction with the attached Figures 1 - 3 for a more detailed description.
[0038] Embodiment:
[0039] An integrated steel cofferdam for crossing a box culvert, as Figure 1 shown, includes a steel cofferdam structure 1 arranged in the box culvert corridor. The steel cofferdam structure 1 includes a water retaining plate 11, a support assembly 12, and a diversion pipe 13. Among them, two groups of water retaining plates 11 are provided. One group of water retaining plates 11 is respectively arranged on the upstream side and the downstream side of the box culvert to form an effective blockage of water. The support assembly 12 is arranged between the two groups of water retaining plates 11 and is firmly connected to the water retaining plate 11 to play a role in stabilizing the entire steel cofferdam structure 1. The diversion pipe 13 is installed through between the two groups of water retaining plates 11 to play a role in guiding the water flow and ensure the smooth progress of the construction.
[0040] Specifically, as Figure 1 shown, each group of water retaining plates 11 includes two steel plates 111 arranged in parallel. During construction, soil is backfilled between the two steel plates 111 arranged in parallel to ensure that the water retaining plate 11 has sufficient strength to withstand the pressure and impact of the water flow. At the same time, the thickness of the steel plate 111 is greater than the thickness of the diversion pipe 13 to ensure that the steel plate 111 is not easily deformed, providing better structural strength and stability, and the length of the steel plate 111 is consistent with the width of the box culvert to ensure that the water retaining plate 11 can completely cover the width of the box culvert and prevent water from leaking from the side.
[0041] In addition, as Figures 1 - 2As shown in the figure, in order to further ensure the tightness of the cofferdam, seals 3 are provided at both ends of the two groups of water retaining plates 11. These seals 3 are closely attached to the gaps between the water retaining plates 11 and the culvert, greatly improving the tightness of the steel cofferdam structure 1. This not only effectively reduces the situation of water seeping into the construction area through the gaps, but also ensures the dryness of the construction environment, thereby improving the construction quality and safety. Among them, in this embodiment, the material of the seal 3 is rubber.
[0042] As Figures 1 - 2 shown in the figure, the support assembly 12 includes four support bars 121. The four support bars 121 are perpendicular to the steel plate 111, optimizing the stress state of the support bars 121 and firmly connecting them to the steel plate 111 by welding, providing a more stable support framework for the steel plate 111. By setting multiple support bars 121, the load-bearing capacity and stability of the overall structure have been significantly improved, and it can better cope with complex and changeable construction environments and water flow conditions.
[0043] In addition, as Figure 1 and 3 shown in the figure, in order to further enhance the stability of the water retaining plate 11, two reinforcing ribs 113 are also provided between the two parallel steel plates 111. The two ends of these reinforcing ribs 113 are welded to the steel plate 111, effectively enhancing the compressive capacity of the steel plate 111 and making the entire water retaining plate 11 more durable.
[0044] As Figures 1 - 3 shown in the figure, two support seats 2 are installed at the bottom of the diversion pipe 13. The two support seats 2 are spaced apart, effectively dispersing the weight of the diversion pipe 13, enhancing the stability of the diversion pipe 13 in the cofferdam, reducing the influence caused by uneven ground on the diversion pipe 13, and providing a stable support for the diversion pipe 13.
[0045] As Figures 1 - 3 shown in the figure, two lifting holes 112 are opened near the top of each steel plate 111. The two lifting holes 112 are symmetrically arranged. The existence of the lifting holes 112 greatly facilitates the lifting operation of the entire steel cofferdam structure 1. During the construction process, the steel cofferdam structure 1 can be easily installed at the predetermined position through the lifting holes 112 by using lifting equipment, thereby improving the construction efficiency.
[0046] Working principle: During the construction process, the steel cofferdam structure 1 is integrally placed at the predetermined position in the culvert by using lifting equipment. After placement, the bottom gap is sealed with waterproof cement mortar, and blocks are laid with waterproof cement mortar around it. The water in the middle of the steel cofferdam structure 1 is pumped out. Among them, the water retaining plate 11 effectively blocks the water flow, realizing the effective isolation of the culvert construction area, while the diversion pipe 13 guides the water flow to pass through the construction area smoothly, thereby greatly improving the construction efficiency and ensuring the construction quality.
[0047] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
