Background

With the decrease of urban construction land supply, the development and utilization of underground space are more and more emphasized by people.

In urban planning design, government planning authorities in various regions make out-of-the-way regulations on urban planning design in order to protect original buildings, pipelines, roads and other municipal facilities around planning plots from being damaged. For example, the regulation is given in thirty-fifth article (fourth) of city planning management technology regulation in Shanghai city: the distance from the boundary of the underground building is not less than 0.7 time of the depth of the underground building; the twenty-fourth (third) article in the "Kaiki City construction engineering planning and management technology Specification" (provisional): the distance between the underground buildings and the adjacent land boundary is not less than 0.7 time of the depth of the underground buildings.

Nevertheless, in underground construction, cracking, collapse, and fracture damage of buildings (structures) around the land, underground pipelines, and roads still occur.

More seriously, the development of underground space in long, narrow, irregular and other special areas is almost impossible.

In order to solve the above problems, people are always seeking an ideal technical solution.

Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1, a peripheral structure of underground building engineering inversion construction structure, including first floor structure and substructure, substructure and first floor structure constitute and move back a platform structure, move back the platform part and be regarded as the basement of first floor structure is equipped with first layer waterproof raft 1, the both ends of first layer waterproof raft 1 connect the fender pile of first floor structure and substructure respectively, and in this embodiment, the substructure refers to two layers and below the two layers structure.

In the structure, the first-layer waterproof raft plate 1 plays a role in connecting the first-layer structure with the support piles of the lower-layer structure, when the first-layer support piles 2 are stressed, the first-layer waterproof raft plate 1 is transmitted to the lower-layer support piles 7 to form a Z-shaped whole, and the capacity of resisting damage is greatly enhanced compared with that of a single row of support piles; more importantly, the distance between the height of the first-layer underground space and the surrounding buildings meets the requirement of urban planning management technical regulation, so that the underground space is deeply developed, and the utilization rate of the underground space is greatly improved.

Wherein, the first floor structure includes first waterproof raft 2, first waterproof raft 1, first waterproof wall 3, crown beam 4, first backfill soil 5 and first concrete connection 6, the middle part level of first waterproof raft 1's outer end and first waterproof raft 2 links to each other, and first waterproof wall 3 takes root on first waterproof raft 1, and first backfill soil 5 fills in the space of locating between first waterproof wall 3 and first waterproof pile 2, and first retaining pile 2 top is located to crown beam 4, and first concrete connection 6 is connected between first waterproof wall 3 and crown beam 4.

First floor fender pile 2, first floor waterproof raft 1, first floor bulkhead 3, crown beam 4, first floor backfill 5 and first floor concrete connecting piece 6 have constituted the relay reinforcement structure of a rectangle, when first floor fender pile 2 received the side pressure of peripheral building, partly pressure passes through first floor concrete connecting piece 6, first floor bulkhead 3 transmits to first floor waterproof raft 1 upper end, partly pressure passes through crown beam 4, first floor fender pile 2 transmits to first floor waterproof raft 1 outer end, the pressure that comes from peripheral building has been dispersed effectively, and simultaneously, the relay reinforcement structure self of rectangle also possesses the reinforcement attribute, guarantee the stability of first floor structure.

The substructure adopts conventional mode to go on, and the substructure includes basement raft 8, lower floor's waterproof wall 9, lower floor's fender pile 7, lower floor's backfill 10 and post-cast strip 11, and the inner of first waterproof raft 1 is connected on the top of lower floor's fender pile 7, and the bottom of lower floor's waterproof wall 9 is connected with basement raft 8's outer end, and lower floor's backfill 10 is filled in and is located between lower floor's fender pile 7 and lower floor's waterproof wall 9, and post-cast strip 11 is connected between the top of lower floor's waterproof wall 9 and first waterproof raft 1.

The degree of depth of substructure can excavate as required, need calculate and satisfy compressive strength simultaneously, and lower floor's fender pile 7 not only plays the effect of supporting and protecting lower floor's space, still plays the effect of strutting the first floor space, and on the same hand, the continuous structure of post-cast strip 11, lower floor's waterproof wall 9 and basement raft 8 that founds in the substructure, also further has strengthened the structural strength in whole secret space.

During the concrete construction, the following steps are adopted:

1) constructing a first-layer support pile;

2) digging to obtain the lower elevation of the underground first-layer waterproof raft;

3) constructing supporting piles at the lower layer below the second layer of the underground;

4) constructing an underground first-layer waterproof raft, and connecting two supporting piles at two ends;

5) constructing an underground first-layer waterproof wall;

6) constructing backfill of an underground first layer;

7) constructing the first layer of concrete connected pieces;

8) digging soil to be below the raft;

9) constructing a basal raft;

10) constructing the lower waterproof wall below the second floor and the second floor;

11) constructing backfill on the lower layer below the second layer of the underground;

12) and (5) post-cast strip construction.

The construction is carried out according to the construction steps, the first-layer structure is strengthened before the lower-layer structure is started, and the danger can be avoided when two layers and below the two layers are excavated.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
