Description
Technical field
The present invention relates to foundation pit trestle technical field in deep-foundation pit engineering, specially a kind of recyclable steel concrete combination of assembled
Formula foundation pit trestle work structure and construction method.
Background technology
With Urban Underground Space Excavation, base pit engineering is towards bigger more Shenzhen Development Bank in city, and Foundation Pit Construction field
The narrow neighboring buildings in ground are intensive, more demanding to construction site utilization rate in foundation pit, for such situation, generally pass through in engineering
Construction bridge is set to utilize place inside foundation pit.Common construction bridge is divided into two kinds, when armored concrete trestle, second is that
Steel trestle.
In armored concrete trestle system, trestle beam slab and support system integral cast-in-situ are non-dismountable, disposable,
It is huge that workload is removed simultaneously, causes largely to waste.
In steel trestle system, trestle beam and top trestle plate are laid using steel construction, although it is detachable due to
Material stiffness is small compared with armored concrete, and bearing capacity is limited, therefore suffers from conditionality in actually using, and can not meet complexity
Under the conditions of large-area construction needs.
Before making the present invention, Chinese patent（Application number：CN 107246014A）Disclose " detachable foundation pit trestle body
System and its construction method ", it is characterized in that trestle beam collectively constitutes trestle region with being layed in the steel plate roadbed box on trestle beam top.
It realizes the detachable use of trestle, but has the disadvantages that：（1）It is layed between subgrade case on concrete trestle beam, due to road
Base case size is limited, and trestle beam span and spacing need to strictly meet subgrade case and be laid with requirement so that trestle beam span is smaller, economical
Property is poor；（2）Subgrade case is only fixed by upper reinforcement and side grooves, can not be formed and is reliably connected with trestle beam, stack in construction
Axle load is carried often as dynamic load, only connect the globality for being difficult to ensure that subgrade case with upper reinforcement by groove；（3）Due to trestle
Beam span is limited by subgrade case size, and lower part trestle stand column pile radical is often more, it is difficult to it avoids conflicting with agent structure beam column,
Influence main structure construction.
Chinese patent（Application number：CN 106968256A）Disclose " foundation pit assembled steel trestle construction method ", feature
To use Bailey bracket unit as trestle component, lower part setting steel lattice column, but there are following defects for this method：（1）Bei Lei
Frame element stiffness is smaller, and cannot need to be higher than foundation pit with the horizontally-supported unification of foundation pit, trestle beam absolute altitude and support absolute altitude, foundation pit support
By must fall under trestle beam；（2）Trestle span is limited by Bailey bracket unit, has fixed modulus, it is difficult to meet large span
It is required that；（3）Trestle rigidity is smaller, and Foundation Pit is big.
Therefore, can form one kind there is an urgent need to one kind can have enough rigidity and again conveniently detachable and repeatable make
With the foundation pit trestle work structure with cost and duration advantage.The recyclable steel concrete combined type foundation pit trestle work structure of assembled is this
Under the conditions of come into being, become and solve the problems, such as this means.
