Abstract

The invention discloses a method of newly building an underground space under the ground by a pipe jacking method. The method provided by the invention aims to have the characteristics of small influence on surface buildings, fast construction speed and simple construction. The technical scheme is that the method of newly building the underground space under the ground by the pipe jacking method is carried out by the following steps: 1) excavating a vertical shaft or a foundation trench in a proper position around the ground corresponding to the underground space to be built, wherein either the vertical shaft or the foundation trench shall be deeper than the underground space; 2) jacking either steel pipes or concrete pipes into a to-be-built position in the underground space in either the vertical shaft or the foundation trench, wherein either all the steel pipes or the concrete pipes are mutually arranged in parallel, so as to form a pipe wall with a rectangular cross section; 3) gradually excavating soil in the pipes and soil in the rectangular pipe wall; 4) jacking either the steel pipes or the concrete pipes of small diameters in the soil layers between the adjacent steel pipes or the adjacent concrete pipes; and 5) drilling an injection pipe for grouting in an outer pipe; and solidifying to obtain the underground space.

Description

Method with pipe jacking method in the underground newly-built underground space

Technical field

The present invention relates to a kind of construction techniques, especially the construction method of underground building.

Background technology

Along with the quickening of urbanization process, reduce increasingly in the space that ground space can develop, and has become people's common recognition toward underground development.Because the infrastructure on ground has been tending towards saturated, therefore build the excavation form that underground building adopts and will destroy a large amount of ground installations, long in time limit, pollute greatly, bring to people's life huge constant, do not met the development need of current social.

Summary of the invention

The object of the invention is to overcome the deficiency in above-mentioned background technology, provide a kind of with pipe jacking method in the method for the underground newly-built underground space, that the method should have is little to ground Influence on Architecture, construction speed fast, the simple feature of constructing.

Technical scheme provided by the invention is: the method with pipe jacking method in the underground newly-built underground space, according to following steps, carry out:

1) first wanting to build the underground space corresponding ground periphery correct position excavating shaft or foundation ditch, the degree of depth of vertical shaft or foundation ditch should be greater than the degree of depth of the underground space;

2) in vertical shaft or foundation ditch, toward the underground space want build position level and head into steel pipe or concrete pipe, all steel pipe or concrete pipe are arranged parallel to each other, the pipe wall that to form cross section be rectangle;

3) progressively cut out earth and the rectangular tube earth within the walls in pipe;

4) in the soil layer between adjacent steel pipe or concrete pipe, then head into steel pipe or the concrete pipe that diameter is less;

5) in outer tube, pierce Grouting Pipe slip casting; After solidifying.

All steel pipes or the cylindrical of concrete pipe are tangent.

Adjacent big or small steel pipe forms an entirety by welding or connector.

The area of rectangular tube wall is greater than the cross section of design excavation.

The invention has the beneficial effects as follows: owing to excavating in the bottom of vertical shaft or foundation ditch, significantly reduced the degree that ground infrastructure is destroyed, make to repair and be more prone in the future, thereby significantly reduced cost, shortened the duration, also reduced the traffic of people's trip has been hindered, there is very high social value; The method does not also need to employ too much big machinery, and energy consumption significantly reduces; Be particularly suitable for the location excavation underground space intensive in ground infrastructure.

Accompanying drawing explanation

Fig. 1 is the excavation position view of the underground space of the present invention.

Fig. 2 is that the A-A in Fig. 1 analyses and observe structure for amplifying schematic diagram.

The specific embodiment

Below in conjunction with embodiment shown in the drawings, further illustrate.

Method with pipe jacking method in the underground newly-built underground space, according to following steps, carry out:

1) first determine and want to build the vertically ground periphery correct position of correspondence of underground space K, excavate at least one vertical shaft 1 or foundation ditch, the degree of depth of vertical shaft or foundation ditch should be greater than the degree of depth of the underground space; The length of vertical shaft or foundation ditch and width should be greater than by the steel pipe of top pressure or the length of concrete pipe;

2) vertical shaft or foundation ditch want build position level and head into steel pipe 2 or concrete pipe; The length of steel pipe or concrete pipe should be greater than the length of the horizontal plane projection of the underground space, and all steel pipe or concrete pipe are arranged parallel to each other, and forms the pipe wall that cross section (being Fig. 2) is rectangle (rectangular area is greater than the cross section of design excavation); Distance after being arranged parallel to each other should be greater than the width of the horizontal plane projection of the underground space;

All steel pipes that head into or concrete pipe should be as far as possible mutually close; Optimum selection is that the cylindrical of steel pipe or concrete pipe is tangent.

3) progressively cut out earth and the rectangular tube earth within the walls in steel pipe; Can set up on demand temporary supporting, to guarantee safety;

4) in the soil layer between adjacent steel pipe or concrete pipe, then head into steel pipe 3 or the concrete pipe that diameter is less, to be conducive to the firm of underground soil layer;

5) slip casting in the steel pipe that cuts out earth forms the concrete core steel pipe strengthening after it solidifies.

As recommendation, adjacent big or small steel-pipe welding or form an entirety by connector.
