Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the deep foundation pit reinforcing structure in this embodiment includes at least four baffles 1, where the baffles 1 are made of steel plates or wood plates and can be reused, and when in use, the four baffles 1 are respectively attached to four inner side walls of the foundation pit 100. For the foundation pit 100 with a deeper depth or for the baffle 1 to be convenient to process and transport, each inner side wall of the foundation pit 100 can be overlapped and used vertically (namely the width direction) and horizontally (namely the length direction) by a plurality of baffles 1. Every baffle all includes foundatin plate 11 and expansion plate 12, and expansion plate 12 pegs graft at foundatin plate 11 movably, and expansion plate 12 can be relative foundatin plate 11 along transversely being length direction and remove in order to realize the holistic length adjustment of baffle 1, reduces the quantity of baffle 1, makes the installation more convenient simultaneously. The reinforcing structure of the deep foundation pit 100 in this embodiment further includes at least four recyclable reinforcing plates 2, and the four reinforcing plates 2 are detachably mounted and fixed on the ground and are respectively detachably mounted and fixed on the upper end surfaces of the four baffles 1. The deep foundation pit reinforcing structure in this embodiment further includes a plurality of bracing pieces 3, and the both ends of bracing piece 3 are installed respectively and are fixed in the side of two baffles 1 that are located double-phase offside. All parts of the deep foundation pit reinforcing structure in the embodiment can be repeatedly used, common mechanical mounting and fixing modes are adopted, and compared with concrete pouring, the deep foundation pit reinforcing structure is simple, convenient and quick to mount, maintain and replace supports and dismount, and the construction cost is remarkably reduced.
