Description

A kind of underground pipe gallery structure and sunk type construction method
Technical field
The invention belongs to municipal technical fields, and in particular to a kind of underground pipe gallery structure and sunk type construction method.
Background technique
With the raising of China's economic strength, the Urban Underground pipe gallery as " blood vessel " and " nerve " has become city The main contents of political affairs infrastructure construction.
The height to earth up of pipe gallery is generally between 2-3.5 meters, and buried depth is mostly between 6-8 meters.Because earthing is shallower, institute In such a way that most engineerings are not suitable for shield, push pipe, tunneling.Currently, the form of construction work mainly used is open-cut, including bright Dig the cast-in-place and prefabricated pipe gallery of open cut mode.But inventor thinks open-cut, and there are construction period, difficulty of construction is big, applies The work period is long, cost is high, environmental protection, security problems, specifically:
1) difficulty of construction is big: pipe gallery foundation depth ordinary circumstance is deep basal pit, it is necessary to big according to danger more than 5 meters The special design and construction of engineering progress pattern foundation pit supporting structure.Foundation pit is according to different situations, using slope, soil nailing, steel sheet pile, perfusion The support forms such as stake, engineering method stake, no matter which kind of support form can all increase difficulty of construction using.
2) long construction period: pipe gallery should be by the construction work such as excavation, supporting, precipitation, piping lane main body construction, backfill Sequence, process of construction is long, causes long-term influence to the trip of city inhabitant.
3) cost is high: due to the raising of environmental consciousness in recent years, there be stringent want in country for Dust Improvement, water and soil conservation It asks, therefore, digging fortune, the price of backfilling material of the cubic metre of earth and stone increase exponentially therewith;It needs to excavate in open-cut and be greater than The soil of pipe gallery volume, increases construction cost;
4) environmental issue: larger to original appearance damage of soil body because the excavation range of pipe gallery foundation pit is larger.Meanwhile it backfilling Also it needs to transport outward the materials such as plain soil, sand, aggregate chips, rubble mostly, it is larger to natural environment influence;
5) safety problem: the construction of pipe gallery main body must be completed in foundation pit, and security risk is larger in work progress.
Summary of the invention
The purpose of the present invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of underground pipe gallery structure and sinking Formula construction method.
The first object of the present invention is to provide a kind of sunk type construction method of underground pipe gallery structure, can omit base The process of excavation and support is cheated, working procedure is reduced, reduces construction cost, reduces construction period.
The second object of the present invention is to provide a kind of underground pipe gallery structure, is being based on above-mentioned underground pipe gallery structure Sunk type construction method on the basis of make a kind of underground pipe gallery structure
To achieve the above object, the present invention adopts the following technical solutions: a kind of sunk type of underground pipe gallery structure is applied Work method, comprising the following steps:
Step 1, basement process is carried out to construction site and temporary base is constructed, it is comprehensive that underground is carried out above temporary base The main structure of piping lane makes, and the main structure includes side wall, middle wall, is connected with top plate Vierendeel girder and bottom between adjacent side wall Sheet frame is set a roof beam in place.
The main body mechanism of pipe gallery makes above temporary base, can increase more construction spaces, avoid in master Body mechanism is inconvenient to the problem of constructing after sinking to below ground.
Step 2, the soil between side wall and middle wall excavate and be transported, then excavate the soil of side wall and the lower end Zhong Qiang And transport, main structure gradually declines with the excavation of soil;Until the upper surface of main structure sinks down into setting absolute altitude, stop Excavate soil;
The soil for excavating side wall and the lower end Zhong Qiang can make the lower end surface of the part-structure lose support, side wall and middle wall Lower end surface falls and contacts again with soil, and the decline of main structure can be done step-by-step, and working security is high;In main structure When decline, side wall can replace supporting construction to stop the landslide of two sides soil, ensure that safety in the case where saving process Property.
Step 3, coagulation is poured in bottom plate frame is set a roof beam in place to carry out back cover in the lower space casting concrete of main structure Soil is to form bottom plate;
Step 4, in top plate Vierendeel girder casting concrete to form top plate;
Step 5, backfill is filled in the space above top plate;
Step 6, step 1 is repeated, is constructed along underground pipe gallery extending direction to next section of underground pipe gallery.
The sunk type construction method production of above-mentioned underground pipe gallery structure is utilized in a kind of underground pipe gallery structure Formed, including side wall and middle wall, the side wall and top be fixedly connected respectively with top plate, bottom respectively with bottom plate is fixed connects It connects, the lower part of the bottom plate is equipped with back cover, and top plate Vierendeel girder is equipped in the top plate, is set a roof beam in place in the bottom plate equipped with bottom plate frame.
Setting bottom plate frame sets a roof beam in place, top plate Vierendeel girder is arranged in top plate in the soleplate, can not pour in bottom plate and top plate mixed The support between side wall and middle wall is realized in the case where solidifying soil, and side wall is avoided to be toppled by the lateral pressure of soil.
Beneficial effects of the present invention:
1) it reduces difficulty of construction attenuating: reducing the construction of deep basal pit, using ground construction main body, cut the earth, apply Work is simple.
2) shorten construction period: excavation range can be reduced, the digging fortune of the cubic metre of earth and stone is effectively reduced;Save pattern foundation pit supporting structure, under Precipitation Process during heavy;Pipe gallery two sides backfilling working is saved, meanwhile, the earthing backfill amount at the top of pipe gallery is also significantly It reduces;The whole duration is lowered;
3) it reduces cost: saving the expense of excavation, embankment, supporting construction, precipitation;
4) it is conducive to environmental protection: reduces excavation, fugitive dust is effectively reduced;Backfilling material is substantially reduced, the exploitation to sand, stone is reduced, Effective protection natural environment;It is not required to supporting, avoids the use of steel sheet pile, bored concrete pile, anchor pole, soil nailing etc., effective protection environment.
5) safety is higher: the construction of main body is completed on ground, and the safety wind that worker constructs in deep basal pit is effectively reduced Danger;Sinking construction mode effectively avoids the security risk of deep basal pit;Periphery coverage is reduced, guarantee closes on building and structure Build the safety of object.
