Description

Technical Field

[0001] The utility model relates to the technical field of foundation pits, in particular to a foundation pit supporting device with high-strength support. Background Art

[0002] The foundation pit is an earth pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings on site, and waterproofing and drainage work should be done well. For those who excavate shallowly, the slope can be stabilized by placing a side slope. The slope size is determined according to relevant construction regulations. Among them, the "a foundation pit support device" disclosed by the authorization announcement number "CN211873023U" has solved the problem that in the formation process of traditional ground-connected walls, it is necessary to pre-excavate a support groove on the periphery of the foundation pit to be excavated, fill the support groove with mud, and then place a steel cage in the mud. The ground-connected wall is formed by pouring concrete under the mud. The above-mentioned implementation method has the problems of easy collapse of the support groove, uneven surface of the ground-connected wall, easy leakage of reinforcement in the ground-connected wall, and easy leakage of water in the gaps between the segmented ground-connected walls, which leads to the disadvantages of difficult to ensure the quality of underwater concrete pouring and poor reliability. However, in actual use, the foundation pit support device with similar structure still has many defects, such as: the existing foundation pit support device has a simple structure and a single fixing method, and it is easy to deform and tip over due to uneven force during the support process, so it is necessary to design a foundation pit support device with high-strength support.
