Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. According to the following description, the purpose, technical solution and advantages of the present invention will be more clear. It should be noted that the described embodiments are preferred embodiments of the present invention, but not all embodiments.

[0034] A construction method for horizontal expansion of an existing underground space, comprising the following steps:

[0035] S1. The construction needs to expand the space maintenance structure 2 of the underground space area 1. The plan and elevation after construction are as follows figure 1 with figure 2 shown.

[0036] S2. Use the existing underground space 3 to carry out horizontal soil reinforcement for the underground space area 1 that needs to be expanded, and refer to the elevation after construction image 3 .

[0037] S3. Remove part of the existing undergroun...

Abstract

The invention relates to an existing underground space horizontal expanding construction method which mainly comprises the following technical steps that a space maintenance structure of a to-be-expanded underground space area is constructed; soil horizontal reinforcement is carried out on the to-be-expanded underground space area; box culvert jacking construction is carried out on the to-be-expanded underground space area so that a box culvert is formed and acts as a working space for horizontal expanding construction; positions for placing upright columns and piles are measured according toa drawing, holes are formed in the box culvert correspondingly, construction is carried out in a one-column-and-one-pile manner; foundation underpinning of a B1 layer of the to-be-expanded undergroundspace area is carried out, soil of the B1 layer is excavated, and structure construction in the area is carried out; structure construction is carried out in the box culvert in a reverse layer-by-layer manner from a B2 layer; and finally a box culvert structure is dismounted and the structure construction of an undermost layer is carried out. The effect that on the premise of keeping the state ofan original scene of an already completed building, horizontal expanding is carried out on an existing underground space of the building is realized, and operation disturbance on the existing building above is reduced.

Description

technical field [0001] The invention relates to a construction method for horizontal expansion of underground spaces of existing building groups, and belongs to the technical field of construction engineering. Background technique [0002] The central urban area of ​​a city is generally the administrative center, cultural center or economic center. The central urban area is not only the gathering sink of the city, but also the radiation source of the city. With the development of the economy, the economic agglomeration degree of the central urban area will continue to increase, the distribution density of residents will continue to increase, and the number of building groups will continue to increase, which poses certain challenges to the development of the central urban area. [0003] At present, as an important direction for the sustainable transformation of the central urban area, the expansion and reconstruction of the underground space of the existing buildings in the c...
