Detailed Description
The invention will be further explained with reference to the drawings and the specific embodiments.
Referring to fig. 1, the utility model provides a local pit structure that falls in deep basal pit can promote the stability of local pit. The structure of the local deep pit in the deep foundation pit of the present invention is explained with reference to the accompanying drawings.
As shown in fig. 1, the utility model discloses the structure of the pit that partially falls in deep basal pit is including the local pit 100 that is formed at the foundation ditch bottom surface, locating the fore shaft shaped steel roof beam 11 at local pit edge and support shaped steel roof beam 12 in local pit that supports horizontally. Wherein, fore shaft shaped steel roof beam 11 and foundation ditch bottom surface flush, support shaped steel roof beam 12's tip and the fore shaft shaped steel roof beam 11 fixed connection that corresponds support it.
The utility model discloses the part deep pit structure that falls in deep basal pit is still including laying the concrete cushion 200 in the foundation ditch bottom surface, and a plurality of enhancement shaped steel 21 have been buried underground in the concrete cushion 200. The reinforcing section steels 21 are arranged in a staggered manner in the transverse and longitudinal directions.
The combination is as shown in fig. 3, the steel frame 12 is H-shaped steel, its web is vertically arranged and the flange plate is horizontally arranged, and vertical rib plates are fixedly arranged on the web, and the rib plate at the side of the steel frame 12 corresponding to the reinforcing steel 21 is formed with a convex connecting plate 111. The reinforced section steel 21 is also H-shaped steel, the web plate of the reinforced section steel 21 is vertically arranged, the flange plate is horizontally arranged, and the connecting plate 111 is welded and fixed with the end part of the web plate of the corresponding reinforced section steel 21, so that the reinforced section steel 21 is fixedly connected with the locked-notch steel beam 11. The stability of concrete cushion 200 has been strengthened through setting up of reinforcing steel 21, further through reinforcing steel 21 and fore shaft shaped steel roof beam 11 welded fastening to fix concrete cushion 200 and support in the fore shaft shaped steel roof beam 11 at local pit 100 edge and become one, promoted the stability of local pit.
