Embodiment 1

[0039] A construction method for an underground structure, comprising the steps of:

[0040] Step 1: Excavate a groove with a predetermined depth along the outermost 2 inside of the soil body 1 around the underground building with a claw bucket or an underground diaphragm wall excavator. The design depth of the center pillar 12 and the width of the groove are equal to or slightly smaller than the section width of the enclosure structure;

[0041] Step 2: press the enclosure corner column 11 to the design depth by static pressure at the corner of the underground building;

[0042] Step 3: press the enclosure center column 12 to the design depth by static pressure between the corners of the underground structure;

[0043] Step 4: Between the adjacent enclosure corner columns 11 and / or enclosure center columns 12, the enclosure panels 13 are pressed into the design depth by static pressure;

[0044] Step 5: excavate the soil body 10 in the enclosure structure, and clean up the ...

Embodiment 2

[0048] A construction method for a multi-storey underground building, comprising the steps of:

[0049] Step 1: Excavate a groove with a predetermined depth along the outermost 2 inside of the soil body 1 around the underground building with a claw bucket or an underground diaphragm wall excavator. The design depth of the center pillar 12 and the width of the groove are equal to or slightly smaller than the section width of the enclosure structure;

[0050] Step 2: press the enclosure corner column 11 to the design depth by static pressure at the corner of the underground building;

[0051] Step 3: press the enclosure center column 12 to the design depth by static pressure between the corners of the underground structure;

[0052] Step 4: Between the adjacent enclosure corner columns 11 and / or enclosure center columns 12, the enclosure panels 13 are pressed into the design depth by static pressure;

[0053] Step 5: excavate the soil body 10 in the enclosure structure, and cl...

Abstract

The invention provides an underground building. During construction, the outermost side of surrounding soil is in direct contact with the side surface of an enclosure structure; and the enclosure structure comprises enclosure corner posts, enclosure middle posts and enclosure plates. The underground building is characterized in that the underground building is constructed by a method comprising the following steps: excavating grooves with predetermined depth by a gripper or an underground continuous wall excavator along the inner part of the outermost side of the surrounding soil of the underground building, and vertically pressing the enclosure corner posts, the enclosure middle posts and the enclosure plates into the soil until designed depth by adopting a hydrostatic mode; excavating out the soil in the enclosure structure, and clearing the exposed surface of the enclosure structure; injecting waterproof mortar into gaps between the enclosure corner posts and / or the enclosure middle posts and the enclosure plates; and casting an exterior wall, a bottom plate, floors and the enclosure structure of the underground building as a whole, thereby forming a main body structure of the underground building.

Description

technical field [0001] The invention relates to the technical field of underground construction, in particular to a method for constructing a multi-storey underground building. Background technique [0002] When constructing underground buildings, in the prior art, sheet piles, underground diaphragm walls, etc. are usually used to form retaining walls, and then a formwork is built in a small space between the retaining wall and concrete is poured in the completed formwork Forms the walls of underground structures. [0003] In this traditional construction method, when excavating the foundation, it is necessary to dig out additional space to ensure the space required for building the formwork, and at the same time, it also causes an increase in the amount of excavated earthwork, especially in the construction of urban reconstruction. There is usually only a limited distance between the newly built underground buildings and the original buildings that need to be preserved, wh...
