Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: a foundation pit inner supporting structure comprises a slope protection plate 2 arranged at the upper edge position of a foundation pit 1 and transverse supporting rods 3 horizontally arranged and used for fixing and supporting, wherein the slope protection plate 2 is fixedly arranged in the foundation pit through a plurality of bolts, the slope protection plate 2 not only can play a role in supporting and protecting the side wall of the foundation pit 1, but also can play a role in protecting the soil at the edge position of the foundation pit and prevent the soil at the edge position from collapsing, the transverse supporting rods 3 are fixedly connected with the slope protection plate 2 through a plurality of bolts, the transverse supporting rods 3 are provided with a plurality of sections, flange rings 4 are arranged at two ends of each of the plurality of sections of transverse supporting rods 3, and the transverse supporting rods 3 are fixedly connected through the flange rings 4 and the bolts;
the slope protection plate 2 comprises a horizontal protection plate and a side wall protection plate, the horizontal protection plate and the side wall protection plate are integrally formed, the lap joint groove 21 is formed in the surface of the external corner of the slope protection plate 2, the joint groove matched with the lap joint groove 21 for use is formed in the surface of the internal corner of the slope protection plate 2, when the slope protection plate is installed, the adjacent slope protection plates 2 are overlapped with each other, so that the slope protection plate 2 is integrally connected, the whole stability can be improved, and a better water retaining effect is achieved.
