Description
Technical field
The invention belongs to hypogee technical field, more particularly to a kind of underground space structure of covered back-digging construction
Construction method.
Background technique
Urban transportation construction at present is like a raging fire, and the new round that China big and medium-sized cities will start underground engineering construction is high
Tide, due to the scarcity of the underground space, to collection, " Urban Underground pipe gallery, Urban Underground expressway, urban underground construction are empty
Between " Urban Underground Complex demand it is huge.
The exploitation and construction of Japan and the American-European underground space maintain the leading position, and advocate at first and propose underground city and city
The synthesization of city's underground space and three-dimensional utility strategies, nineteen ninety propose Tokyo Declaration: the Devoting Major Efforts To Developing underground space, start people
Class new cave period, International Tunnelling Association in 2010 expand to tunnel and underground space association and declare: 21 century is underground
The century in space.
To mark international metropolis, become extensive style, booth large flat bread urban development pattern into intensive, solid mode, to underground
Want space；Break through urban land, air, water source, greenery patches, the per capita constraint of the resource environments total amount such as city space, the energy, environment；
Sea, greening deficiency, real estate finance transition, old town are seen to traffic congestion, air dirt, noise pollution, visual pollution, city
The urban disease that the tricks such as vigor decline incur life carries out comprehensive improvement；Change made in China cultivates height leading in the world into Created in China
Hold industry cluster.
Cities of Foreign Countries underground space development is with a long history, mostly combines commercial facility with Large Underground transport hub and stops
Parking lot holds a variety of traffic forms in the underground space synthesis type presentation of one.In the world, Japan and America and Europe are in underground sky
Between exploitation and construction maintain the leading position, advocate and propose the synthesization and solid of underground city and urban underground space at first
Change utility strategies.Totally see have out when including many countries of underground space synthesis of multiple transportation modes or multiple functions
It is existing, but underground structure cutting depth is deeper at present, material utilization amount is larger, and risk is larger in the construction process, and underground is empty
Between utilization rate it is lower.
Summary of the invention
In order to solve the above-mentioned technical problems, the present invention provides a kind of constructions of the underground space structure of covered back-digging construction
Method the problems such as to solve " underground space utilization rate is low, and material utilization amount is big ", not only saves construction investment, but also increase
The safety of construction and reliability of structure.
Technical scheme is as follows:
A kind of construction method of the underground space structure of sheltered reverse excavation construction, comprising the following steps:
A, in road surface two sides excavation pit to negative one layer bottom；
B, compacting foundation, and carry out dealing with foundation；
C, side column is poured in the foundation pit above the foundation of two sides, after side column molding is firm, Retaining Wall is set；
D, original road surface is removed；
E, lid sets top plate above two sides side column and retaining wall；
F, center pillar is set after excavating soil to certain position；
G, crossbeam is set between two sides side column and center pillar；
H, continue to excavate soil forward, and repeat d, e operation；
I, after soil excavates completely, it is laid with bottom plate.
Further, it is excavated when the excavation of foundation pit along original road surface two sides, when excavation does not destroy original road surface, excavates
Width is 2 ~ 3 times of side column width, is convenient for cast in situs side column.
Further, for the excavation of foundation pit to bottom plate lower part 2m or so, foundation top edge and bottom plate lower edge are flat
Together, foundation width and foundation pit are of same size, and foundation is uniformly poured with side column.
Further, the top plate width is greater than the distance between two side columns, and top plate two sides are more than that the edge of side column is taken
On soil, top plate and its top weight a part are undertaken by side column and retaining wall, and a part is undertaken by two sides soil.
Further, in the same horizontal line, crossbeam two sides and two side column assembleds connect for the side column and center pillar setting
It connects, is connect among crossbeam with center pillar assembled.
Further, underground is divided into first interval, second interval to along the longitudinal direction by the side columnnSection is opened
Dig first interval when, soil is directly transported by shield machine rear, excavate first interval after, stop excavate, setting center pillar and
Crossbeam, after setting completed, continuation excavate forward second interval, and soil is transported by the traffic aisle between center pillar and two sides side column
It is defeated, center pillar is set and crossbeam repeats above operation after setting completed, is excavated until completing all section soil.
Further, the soil cutting depth is to basic top edge, after excavation, carries out base plate paving, bottom plate
It gets around side column and center pillar is arranged between the retaining wall of two sides.
Further, the side column, retaining wall, center pillar are connect with top plate assembled.
The beneficial effects of the present invention are: this method is constructed using sheltered reverse excavation, construction depth is shallow, and vertical supporting need not be held
Soil body weight is carried on a shoulder pole, reliability of structure is increased, upper and lower traffic forms unified entirety, increases the globality of structure, lower part is applied
Work does not influence ground vehicle pass-through, and the present invention greatly improves the security performance of structure, shortens construction period, saves construction material,
Reduce production cost.

Foundation pit 2 is excavated to 8 lower part 2 of bottom platemLeft and right, 1 top edge of foundation is concordant with 8 lower edge of bottom plate, width and base
It cheats 2 of same size, is uniformly poured with side column 3.
5 width of top plate is greater than the distance between two side columns 3, and 5 two sides of top plate are more than that 3 edge of side column rides on soil, top plate 5
And its top weight a part is undertaken by side column 3 and retaining wall 4, a part is undertaken by two sides soil.
In the same horizontal line, 7 two sides of crossbeam are connected with two side columns 3 for side column 3 and the setting of center pillar 6, centre and 6 phase of center pillar
Even.
Underground is divided into first interval, second interval to along the longitudinal direction by side column 3nSection, when excavating first interval, soil
Earth is directly transported by shield machine rear, after excavating first interval, is stopped excavating, center pillar 6 and crossbeam 7 is arranged, setting completed
Afterwards, continue to excavate second interval forward, center pillar 6 is arranged by the traffic aisle transport between center pillar 6 and two sides side column 3 in soil
It repeats above operation with crossbeam 7, is excavated until completing all section soil after setting completed.
Underground cutting depth after excavation, carries out bottom plate 8 and is laid with, bottom plate 8 is arranged two to basic 1 top edge
Between side block cob wall 4, side column 3 and center pillar 6 are got around.
Side column 3, retaining wall 4, center pillar 6 are connect with 5 assembled of top plate.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
