Description
Technical Field
The utility model belongs to the technical field of deep basal pit engineering, especially, relate to a deep basal pit steel case roof beam bearing structure.
Background
The foundation pit is an earth pit excavated at a foundation design position according to the base elevation and the foundation plane size, and the foundation pit engineering mainly comprises the design and construction of a foundation pit supporting system and the excavation of earth, so that the foundation pit is a system engineering with strong comprehensiveness.
In the foundation pit engineering, an underground space is excavated downwards from the ground, and as a new excavation end surface is formed after excavation, the stability of the original structure of a rock mass is damaged, and safe construction such as landslide, collapse and the like is easy to occur in the construction process; in order to protect the stability of foundation pit engineering, the inner side wall of a pit is generally provided with a supporting structure; the foundation pit supporting structure adopts retaining, reinforcing and protecting measures for protecting the construction of an underground structure and the safety of the surrounding environment of the foundation pit.
In present subway construction foundation ditch, generally adopt concrete structure bearing structure, but concrete structure's cost is high, is difficult for demolising the reuse of not being convenient for after the construction.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model adopts the following technical scheme:
the deep foundation pit steel box girder supporting structure comprises a plurality of steel box supporting girders which are transversely arranged,
a box girder connecting beam is connected between two adjacent steel box supporting beams;
anchoring parts are arranged at two ends of the steel box supporting beam;
the box girder connecting beam is connected to the steel box supporting beam through a detachable connecting assembly;
the detachable connecting assembly comprises a first connecting piece arranged on the side edge of the steel box supporting beam,
and the second connecting piece is arranged at the end part of the box girder connecting and tying girder.
In one mode, the first connecting piece is an inner expanding strip-shaped clamping groove, and the second connecting piece is an outer expanding strip-shaped clamping piece.
In one mode, the upper port of the first connecting piece is communicated with the upper side face of the steel box supporting beam.
In one form, the second connector is insertable into the first connector from the upper port.
One way, the steel box support beam is connected at both ends to the fender post.
In one mode, the steel box supporting beam is anchored to the reinforced concrete ring beam of the fender pile through an anchoring part.
In one mode, the lower parts of the steel box supporting beam and the box beam connecting beam are connected and provided with upright posts.
The utility model has the advantages that:
1. the disassembly is convenient, so that the support structure can be repeatedly utilized;
2. saves resources and reduces the engineering cost.
Drawings
Fig. 1 is a reference diagram of a usage state of the present invention;
FIG. 2 is a schematic structural view of the present invention;
