Embodiment

[0043] See attached figure 1 to attach image 3 , the present application provides a foundation pit reinforcement support device 1, including sheet piles 11 arranged at both ends of the foundation pit at the side walls and a combined support portion 12 supported between the sheet piles 11;

[0044] The combined supporting part 12 includes a sliding card slot 121 provided on the sheet pile 11, a purlin 122 provided on the sliding card slot 121, and a purlin 122 provided between the two purlins 122. The horizontal brace 123 that is used for supporting between.

[0045]As mentioned above, the foundation pit is an earth pit excavated at the foundation design position according to the base elevation and foundation plane size. Before excavation, the excavation plan should be determined according to the geological and hydrological data, combined with the conditions of the nearby buildings, and the waterproof and drainage work should be done well. If the excavation is not deep, the...

Abstract

The application relates to a foundation pit reinforcement supporting device. The foundation pit reinforcement supporting device comprises sheet piles provided on the sidewalls of both ends of the foundation pit and a combined support portion supported between the sheet piles; the combined support portion includes sliding slots provided on the sheet piles, two purlins on the sliding slots, and a brace arranged between the two purlins for support. With the segmented design, the foundation pit reinforcement supporting device can be integrally and independently constructed according to the local conditions, and can be constructed and assembled in different foundation pit sections. In different geological environments in the premise of safe construction, different costs of foundation pit reinforcement support devices can be selected, and cost can be well controlled. The purlins can slide longitudinally, the mounting process is simple and fast, labor intensity is reduced, and work efficiency is improved. Through the bolt holes reserved on the sheet piles, the combined support portion is connectively fixed on the sheet piles in a bolt manner, and the steel wire rope is used to strengthen the purlin, which increases the safety of the construction and ensures the safety of the construction work to a certain extent.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a reinforcement and support device for foundation pits. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base level and foundation plane size. Before excavation, the excavation plan should be determined according to the geological and hydrological data, combined with the conditions of the nearby buildings, and the waterproof and drainage work should be done well. If the excavation is not deep, the side slope can be used to stabilize the soil slope, and the slope size is determined according to the relevant construction regulations. For those with deep excavation and nearby buildings, the foundation pit wall support method, shotcrete retaining wall method, and large foundation pit even adopt methods such as underground diaphragm wall and column-type bored pile interlocking to prevent the...
