Description
Technical field
The utility model is related to the technical field of civilian infrastructure construction, specially a kind of foundation pit supporting construction also serves as master
The pipe gallery of body.
Background technology
Pipe gallery is to be built in Urban Underground for accommodating the urban pipelines such as water supply, draining, natural gas, electric power, communication
Among two kinds and its more than box culvert tunnel.Unified planning and the pipe of city planting ductwork may be implemented by the construction of pipe gallery
Reason.With the needs of urban development, it is extremely urgent to build this intensive municipal pipeline cabin of pipe gallery.From 2013
It rises, State Council lives to build the departments such as portion, the Ministry of Finance and continuously issues multinomial policy, opinion, actively develops pipe gallery and builds pilot city
City carries forward vigorously the development ＆ construction of pipe gallery.Portion, Ministry of Finance's development pipe gallery pilot work are firmly built from 2015, in the first batch
10 experimental cities, the 2nd batch of 15 experimental cities, have thus started the curtain that domestic pipe gallery is built energetically.
Existing pipe gallery construction is mainly two kinds of excavation and cast-in-place formula and precast splice type.The step of excavation and cast-in-place formula master
It is：On ground excavation pit-pattern foundation pit supporting structure-pipe gallery formwork, pour.Pattern foundation pit supporting structure mainly uses in this fashion
Campshed supporting or suspension roof support, suspension roof support cannot play the purpose that intercepts water for underground water, can only be on piping lane foundation pit ground
It is used in the case of on water level located underground, simultaneously because anchor pole cannot generally be removed after the completion of pipe gallery construction, meeting
For pipe gallery both sides the underground space pollution, also for the later stage for the underground space around piping lane utilization very not
Profit.Campshed supporting is intercepted generally for underground water, has the function of preferably to intercept water, but it is equally existed in integrated pipe
The drawbacks of cannot generally being removed after the completion of corridor construction.Precast splice type uses the prefabricated component that standard is made in factory, transports and applies
Lifted to workshop.This form of construction work is also required to carry out foundation pit excavation and bracing, exists and excavation and cast-in-place formula pattern foundation pit supporting structure
Identical problem, meanwhile, such pipe gallery assembly seam is more, and water-proof treatment technology is complicated, and waterproof reliability is not high.
Utility model content
For problems of the prior art, the utility model provides the synthesis that a kind of foundation pit supporting construction also serves as main body
Piping lane, simple in structure, reasonable design, technology requirement is less, easy for construction.
The utility model is to be achieved through the following technical solutions：
A kind of foundation pit supporting construction also serves as the pipe gallery of main body, including side plate, top plate and bottom plate, and by side plate, top
The piping lane cabin that plate and bottom plate surround；
The side plate includes the diaphram wall of side plate inner ring and foundation pit supporting construction, and side plate inner ring is fixed on underground company
The inside of continuous wall；
The top plate is the top cross-brace plate in reinforced concrete member in foundation pit supporting construction, and top is laterally propped up
The both ends of fagging are fixedly connected with diaphram wall respectively；
The bottom plate is armoured concrete slab, setting in bottom of foundation ditch, both ends with diaphram wall and side plate inner ring
It is fixedly connected.
Preferably, if the inner wall of diaphram wall is provided with dry hole；Side plate inner ring is in reinforced concrete member, in side plate
Steel tie corresponding with drilling is provided on the steel reinforcement cage of circle, steel tie is fixed in drilling implantation diaphram wall to be connected
It connects.
Further, the inner wall of diaphram wall is serrated, and is fixedly connected for the cast concrete with side plate inner ring.
Preferably, the steel reinforcement cage of the steel reinforcement cage of top cross-brace plate and diaphram wall is fixed in roof intersection region and is connected
Composition inverted U is connect, and formed by integrally casting is molded.
Preferably, bottom plate is fixedly connected by the steel tie of implantation with diaphram wall and side plate inner ring.
Preferably, horizontally disposed in piping lane cabin to have intermediate lateral support plate, for piping lane cabin to be carried out
Lower separation；The side wall that intermediate lateral support plate both ends correspond to the compartment with piping lane cabin respectively is fixedly connected.
Preferably, it is vertically provided with middle partition board in piping lane cabin, for piping lane cabin to be carried out left and right separation；In
Partition board both ends are fixedly connected at the top and bottom of the compartment with being corresponded in piping lane cabin respectively.
Preferably, the both ends of the bottom plate are fixedly connected on the middle part of diaphram wall.
Compared with prior art, the utility model has technique effect beneficial below：
The utility model passes through armored concrete using the diaphram wall in foundation pit supporting construction as side plate external structure
The top cross-brace plate of component, so that top cross-brace plate has pair of support pattern foundation pit supporting structure and structural body portion
Recast is used, and when lower part soil mass of foundation pit is excavated, top cross-brace plate is all higher than tradition as cross-brace, intensity with rigidity
Beams of concrete and girder steel, foundation pit cross-brace is safe and reliable, without set up other forms cross-brace.Also, due to
The overall stiffness that diaphram wall has and the preferable advantage of intensity, make full use of diaphram wall, make in the present invention
Its double action with the vertical earth-retaining of foundation pit and comprehensive pipe gallery structure side plate.In this way not only so that pattern foundation pit supporting structure
It is more preferable compared to traditional campshed mode water blocking, and since diaphram wall is directly as the external knot of pipe gallery side plate
Structure so that excavation of foundation pit size is reduced, while solving the dirt of the underground space caused by can not being removed due to foundation pit supporting construction
The problem of dye is with waste.Foundation pit supporting construction is poured first in construction, after foundation pit supporting construction intensity is met the requirements, so that it may
With the top cross-brace plate of backfill covering pattern foundation pit supporting structure, greatly reduced in this way since pipe gallery open-cut is for ground
The influence of road etc..
Further, due to still having a part of diaphram wall below the bottom plate of pipe gallery, therefore consider in the later stage
When pipe gallery dilatation directly soil body casting concrete plate, concrete slab and diaphram wall can be excavated in existing bottom plate lower part
Closed internal piping lane cabin is connected and composed, this extending capacity reformation method is convenient, and transformation process is underground job, for
On the ground influence it is less, or even do not influence on the ground.
