Embodiment 1

[0051] Embodiment 1: a kind of method that is applicable to the underground building of brick-concrete structure, is suitable for such as figure 1 and figure 2 The brick-concrete structure building shown has a wall 1 , a strip foundation 2 and a structural beam slab 3 , and a part of the wall 1 and the strip foundation 2 are located in the surface foundation soil 4 .

[0052] The method for adding layers underground to the concrete building of the brick-concrete structure mainly includes the following steps:

[0053] refer to image 3 and Figure 4 As shown, excavate the surface foundation soil 4 above the strip foundation 2 of the building, and the horizontal and vertical strip foundation 2 below the wall 1 of the building are all exposed. The surface foundation soil 4 and the foundation pit side slope 6 formed during the excavation process are grading structures to prevent the foundation pit from collapsing during the excavation process.

[0054] refer to Figure 5 and...

Embodiment 2

[0062] Embodiment 2: a kind of building, this building is brick-concrete structure, and its structure is as Figure 13 and Figure 14 As shown, the building has a wall 1, a strip foundation 2 and a structural beam slab 3, and there is a newly added basement and garage below the building;

[0063] Wherein, the newly added basement and garage are constructed by the method described in Embodiment 1.

Abstract

The invention relates to a method suitable for underground storey addition of a brick-concrete structure building and a building, belonging to the technical field related to constructional engineering. The method mainly comprises the following steps: (A) excavating the part above the strip foundations of the brick-concrete structure building and the earthwork of a planned underground garage area until the foundation of the building is totally exposed; (B) constructing multiple concrete underpinned piles between the strip foundations and on the outer side of the strip foundations; (C) fixedly connecting the pile top of each concrete underpinned pile with a horizontal underpinned beam, wherein the horizontal underpinned beam penetrates through the building wall; (D) arranging concrete jacketed wall beams on the two sides of the building wall, and fixedly connecting the concrete jacketed wall beams with the building wall; (E) removing original strip foundations of the building; (G) excavating the foundation soil below the building till reaching the floor elevation of the planned basement and garage; (H) constructing the floor, the floor slab of each storey and the roof from bottom to top; (I) pouring a new concrete outer wall around the garage and building a partition wall below the building; and (J) backfilling the earthwork till reaching the natural ground.

Description

technical field [0001] The invention relates to the relevant technical field of construction engineering, in particular to a method and building suitable for underground building of brick-concrete structure. Background technique [0002] Orderly, reasonable, comprehensive and efficient development and utilization of underground space resources of existing buildings has become one of the most effective ways to expand infrastructure capacity, improve urban comprehensive disaster prevention capabilities, improve land use efficiency and save land resources. According to the requirements of urban planning, most new buildings have considered the development and utilization of underground space. [0003] However, a large number of existing buildings have not designed underground parking lots and basements due to the lack of forward-looking due to historical reasons. With the increase in the number of cars and the increase in user demand, it is difficult to park and store goods. ...
