Description
Technical field
The present invention relates to Construction Technique of Underground Works field, and in particular to a kind of existing underground space uses no-dig technique mode
The method for carrying out horizontal expansion.
Background technology
It is to realize the important hand of urban sustainable developmentization development using the underground space under conditions of land resource is increasingly deficient
Section.The developed countries such as Japan, the U.S., the underground of " networking, three-dimensional, intensive, deep layer, synthesization " is advocated for a long time
Space utilization theory, achieve extraordinary effect.In the urban underground space construction starting evening in China, it is single to build more presentations
The characteristics of changing, fighting separately.Such as the mutual independence in Shanghai Lujiazui's finance core space underground space, reduce underground sky
Between resource effective rate of utilization.The technology that interconnects of the underground space turns into the key technology of underground space development.On the other hand,
The built underground space in part can not meet capacity and function requirement.For example, the underground that last century 70, the eighties build is stopped
Garage can not solve the situation of " storehouse is hard to find " of present society appearance, and it is when business that these underground garages are carried out with increase-volume
Need.
Constructed in the existing underground space, it is narrow and small there is construction space, what heavy construction equipment can not be applied
Feature.Existing facility is in use state, and surrounding environment certainly will be influenceed by carrying out transformation to it, and this poses must use
The mode of no-dig technique carries out the construction of engineering.The method that the underground space is built in existing building increasing mainly has vertically extending formula increasing to build, water
Flat extension increasing is built and hybrid increasing is built.It is directly under building that the existing underground space is downward that vertically extending formula increasing, which is built,
Extension.Mode is built in this increasing has the advantages of being not take up the building periphery underground space, but due to depth of foundation to be increased, construction
Difficulty is very big, and cost is very high.The reconstruction of horizontal extension formula is to make full use of building periphery vacant lot or greenery patches, is increased under the greenery patches of vacant lot
Add basement.Though this increasing mode of building need to take the building periphery underground space, relatively vertically extending formula, which increases, builds difficulty of construction
Low, cost can receive.It is to increase horizontal extension reconstruction method and vertically extending formula to build method comprehensive utilization that hybrid increasing, which is built,.
The content of the invention
It is an object of the invention to provide a kind of existing underground space to use the no-dig technique mode method that carries out horizontal expansion,
Construction in small space can be realized using the method for small tube coupling, the influence of surrounding environment will be preferably minimized.
In order to achieve the above object, the present invention is achieved through the following technical solutions：A kind of existing underground space is opened using non-
The method that excavation formula carries out horizontal expansion, is characterized in, comprises the steps of：
S102, more piece tube coupling is constructed successively, set in multilayer multiple row, connected between tube coupling using connector, Mei Yiguan
Section includes the polygonal structures of head and the tail connection；
S104, in the range of tube coupling surrounds without in supporting zone carry out inwall construction；
S106, after the intensity of inwall reaches preset strength standard, temporary support construction is carried out in each tube coupling, and is being faced
When support on apply prestressing force；
S108, upper support is removed, top concrete walls construction is carried out in upper support position；
S110, after the intensity of top concrete walls reaches preset strength standard, remove lower support, enter in lower support position
The concrete walls construction of row bottom；

The construction of horizontal expansion is carried out into the existing underground space.
Also included comprising a step S100, described step S100 before described step S102：
If the existing underground space, which is in, rich in water area, to be needed to carry out foundation stabilization construction to the periphery of the existing underground space,
The space of closing is formed, then carries out drainage operation of drawing water in the inside of the existing underground space, performs step S102 afterwards.
Also included in described step S102 by controlling the mesh openings rate of benchmark tube coupling to realize the control to surface subsidence
System;Described mesh openings rate is the area of cutting panel upper shed and the ratio of the panel gross area.
When also including tube coupling jacking to precalculated position in described step S102, all soil-discharging ports are closed;Described casting
Mouth is arranged on out the bottom of soil cabin.
The construction that assembling reinforcement is carried out in each tube coupling is also included in before described step S104.
Described connector includes the chute and tenon being correspondingly arranged on two tube couplings.
Described tube coupling is headed into soil using the principle of push bench process.

A kind of existing underground space of the present invention carries out the method for horizontal expansion compared with prior art using no-dig technique mode
With advantages below：By widening transformation to the existing underground space, the networking intercommunication of the existing underground space, small sky can be achieved
Between the space of underground installation widen dilatation, the extension energization of single function underground installation, realize that networking astrolabe is scattereded all over like men on a chessboard multi-functional
Urban Underground Complex；By widening transformation to the existing underground space, so as to improve the comprehensive of the existing underground space in inner city
Cyclization border, the overall quality of the inner city underground space is lifted, widen the service function of urban central zone；The present invention was according to both
There is the characteristics of underground space is narrow and small, large-scale construction equipment can not be applied, using the method for " breaking the whole up into parts ", tube coupling is carried out small-sized
Change, modularization, to meet requirement to construction space, tube coupling use grid type opening casting mode, with solution without receiving work
Well, the problem that push-bench head can not recall, while dynamic information construction can be carried out according to ground deformation situation；Inside
Serve as a contrast in work progress, by the way of interim post, repeatedly carry out structure conversion, study liner when tearing steel construction open, realize structure
The construction of inwall；The concrete poured into a mould afterwards forms composite construction form with steel construction, and the bearing capacity of steel construction can also be had
Effect utilizes；Inwall is complete cast-in-place concrete structure, has good water resistance.
