Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit construction, in particular to a T-shaped caliper positioning device. Background Art

[0002] The foundation pit is a pit dug at the design location of the foundation according to the base elevation and the plane size of the foundation. Before excavation, the excavation plan should be determined based on geological and hydrological data and the situation of nearby buildings on site, and waterproofing and drainage should be done. If the excavation is not deep, the slope can be used to stabilize the slope, and the slope size is determined according to relevant construction regulations. For deep excavations and nearby buildings, the foundation pit wall support method and shotcrete wall protection method can be used. Large foundation pits can even use underground continuous walls and column-type bored pile interlocking methods to prevent the outer soil layer from collapsing; if there is no impact on nearby buildings, the well point method can be used to lower the groundwater level and use slope open excavation; in cold areas, natural cold air freezing method can be used for excavation, etc.

[0003] A T-shaped caliper positioning device is needed during the foundation pit construction process. In the prior art, Larsen steel sheet piles can be used for water stopping, soil retaining and foundation pit maintenance. It is one of the most critical processes in the construction process. It has a fast construction speed, low construction cost and is green and environmentally friendly. However, during its construction process, it is often unable to be driven in smoothly due to the influence of the crown beam. When the crown beam is too close to the steel plate-shaped driving part, the hammer head of the vibrating hammer will not be able to continue to penetrate, which seriously limits the driving depth of the steel sheet pile. In order to ensure the driving depth, it is often replaced with a larger length steel sheet pile, which leads to an increase in construction costs, seriously affecting the construction efficiency of the foundation pit construction, and cannot meet the use requirements. Therefore, a T-shaped caliper positioning device is proposed to solve the above-mentioned problems. Utility Model Content
