Embodiment 1

[0051]A semi-underground subway station, the semi-underground subway station at least includes a negative floor, a train floor, a station hall floor and pile foundations, the negative floor and the train floor are all underground, and the lower half of the station hall floor Part is located underground, the upper half of the station hall floor is located on the ground, and the negative floor is set on multiple pile foundations;

[0052] Also comprise water air-conditioning system, described water air-conditioning system comprises underground water source 12, water air-conditioning system 13 and windpipe 14 (filtering device is arranged between underground water source and water air-conditioning system, groundwater is filtered and then transported to water air-conditioning system), the heat of the underground water source 12 is transported to the negative floor 1 or / and the driving deck floor 2 or / and the station hall floor 3 through the water air-conditioning system 13 and the ...

Embodiment 2

[0056] The semi-underground subway station in embodiment 1 adopts following construction technology to carry out construction;

[0057] Such as Figure 1~3 Shown, a kind of construction technique of semi-underground subway station of the present invention, a kind of construction technique of semi-underground subway station, described semi-underground subway station at least comprises negative layer 1, driving board layer 2, station hall layer 3, pile foundation 4 and Drainage chamber 5;

[0058] The drainage chamber 5 is located at the bottom, and a drainage pump 6 is arranged inside the drainage chamber 5, and the drainage pump 6 discharges the accumulated water to the ground through the drainage pipe 9; the entrance and exit 7 of the station hall floor 1 are set higher than the ground platform 8;

[0059] The drainage pump is powered by a battery, which effectively avoids the drainage pump not working properly due to power failure in rainy weather, and the battery is charg...

Abstract

The invention discloses a construction process of a semi-underground subway station. The semi-underground subway station at least comprises a first underground floor, a driving plate layer, a station hall layer, pile foundations and a drainage chamber. The semi-underground subway station construction technology comprises the steps that S1, construction preparation is conducted; s2, post-grouting cast-in-situ bored pile construction is carried out; s3, measuring and setting out; s4, mounting an earth surface drainage system; s5, inserting and driving steel sheet piles; s6, excavation of a foundation pit; s7, foundation pit base treatment; s8, constructing a framework of the negative first floor; s9, backfilling the foundation pit; s10, a support is erected; s11, main bridge box girder construction; s12, the support part is dismantled; s13, a traffic lane plate layer is constructed; s14, the continuous part of the support is disassembled; s15, construction of a station hall layer; s16, the support is completely dismantled; s17, secondary excavation of the foundation pit; s18, constructing a top plate of the negative first floor; s19, secondary backfilling of the foundation pit; s20, the steel sheet piles are pulled out; and S21, construction is completed, and the construction site is cleaned. According to the construction technology of the semi-underground subway station, traffic is not affected, and safety of ground and underground structures is not endangered.

Description

technical field [0001] The invention relates to the technical field of subway station construction, in particular to a semi-underground subway station construction technology and a semi-underground subway station. Background technique [0002] With the development of cities, the population increases; the traffic pressure in large and medium-sized cities is increasing day by day. In order to alleviate the traffic pressure, more and more cities have begun to build subway traffic, and subway stations are one of the most important parts in the process of building subways. In order to facilitate the travel of citizens, subway stations are generally built in areas with large population flow and bustling ground traffic, and there are many and intricate underground pipelines (water pipes, gas, electricity, communication lines, etc.) in the city. The construction has increased a lot of difficulty. [0003] In order to solve the above problems, it is urgent to invent a kind of semi-...
