Description

A kind of Large Underground parking lot structure mechanization method of construction
Technical field
The technical field built the present invention relates to urban underground space more particularly to a kind of Large Underground parking lot structure machine Tool method of construction.
Background technique
It being gradually increased with the development of economy with the living standard of the people, people constantly increase the demand of automobile, and Parking stall problem in short supply is also increasingly serious, in order to solve the problems, such as this respect, successively has devised several parking lots in foreign countries Type, such as large stereo parking lot, small fashioned iron structure parking systems, underground stereo parking lot and Surface parking lots.It is large-scale Sky parking and underground stereo parking lot can accommodate a large amount of vehicle, be to solve the critical facility of parking difficulty, but it is accounted for Ground area is big, it is at high cost to build, and builds the area more developed in business mostly, interior near common street and residential area It is difficult to carry out;Although small steel structure tridimensional Garage occupied area is smaller, limited for urban road space, ratio is built More difficult, that there are docking process is cumbersome for part parking apparatus, and Waiting time is long, once have a power failure or individual mechanical breakdowns will affect entirely The trip of library vehicle with park, will be caused to car owner it is inconvenient for use, and ground three-dimensional type garage hinder pedestrian sight and shadow The daylighting effect for ringing surrounding retail shop, causes very big influence to street entirety landscape.Meanwhile existing open parking ground is mostly sharp With roadside, square or the vacant lot garage parking Lai Zuo, urban road is mostly relatively narrow, in the majority with two-way four-lane or two lanes of mixing, very Vehicle is parked in the right side of vehicle traveling direction by more car owners, occupies a lane, needs when being prepared to stop or prepare to exit garage parking A lane is occupied again, it is easy to cause traffic jam.Some places are transformed into parking in order to increase garage parking, greenbelt Library, or even vehicle is parked on non-motorized lane and pavement, seriously affect road environment and the safety trip of pedestrian.
With the raising of the Devoting Major Efforts To Developing of the underground space, especially Mechanization Level, building underground parking will solve The more practicable method of city parking hardly possible.Current underground parking construction generally uses cut and cover method, this method cost Low, short construction period, but ground environment is destroyed, traffic is blocked, periphery life is seriously affected.For business block and important do Public region etc. do not allow large area excavate ground the case where, it is more obvious using shallow mining method advantage, by construction shaft into Enter underground excavation, does not break ring ground environment substantially.Traditional subsurface excavation method is generally based on artificial or small mechanical equipment operation, construction Progress is slow, and there are biggish security risks.
Summary of the invention
For existing underground parking space utilization is insufficient, construction period is long, Mechanization Level is low, construction safety hidden danger Big technical problem, the present invention propose a kind of Large Underground parking lot structure mechanization method of construction.
To solve the above-mentioned problems, the technical scheme of the present invention is realized as follows:

S3, parking area construction will complete the shield machine after ramp is tunneled and hang out vertical shaft, minor diameter push-bench used instead, by minor diameter Push-bench is placed in ramp, and according to the sequence of construction from centre to two sides, successively each endless tube piece of jacking is until the plane layer stops Vehicle area is fully completed;
S4 removes the section of jurisdiction temporary structure of parking area, performs permanent structure, and the vertical shaft for the upper plane layer of constructing in vertical shaft every Plate, so far plane layer construction are completed, and next plane layer construction is continued;
S5 repeats step S2 ~ S4 on shield machine lifting to vertical shaft partition according to sequence of construction from bottom to top, until last One layer of parking area, which is built, completes;
S6, close to construction passenger lift well and external ramp at Shaft Location, finally finishing completes parking lot.
Preferably, ramp includes horizontal linear section, arc transition section and oblique upper straightway, shield machine edge in the step S2 Dampening flat level, rounding off section and tiltedly upper straightway successively tunnels, horizontal linear section and tiltedly go up straightway with circular arc mistake It crosses section smooth connection and horizontal linear section and oblique upper straightway is mutually perpendicular in floor projection direction.
Preferably, the section of jurisdiction inner sidewall in the step S2 in the horizontal linear section in ramp and close to parking area uses It is fiber concrete material or the less concrete material of steel content.
Preferably, when shield machine reaches corresponding Shaft Location in the step S2, temporary platform is set up, is hung to shield machine Out after vertical shaft, the temporary platform is removed.
Preferably, minor diameter push-bench is placed in the horizontal linear section in ramp in the step S3, along perpendicular to slope The direction in road originates driving, and receives in the horizontal linear section in corresponding ramp.
Preferably, stating section of jurisdiction in step S4 is rectangle or class rectangle, and section of jurisdiction includes concrete roof, concrete floor and two Block steel sidewall;The section of jurisdiction positioned at parking area two sides, outside one side wall are concrete side walls, and steel sidewall is interim knot Structure, concrete structure are permanent structure, and the temporary structure of section of jurisdiction is connected by high-strength bolt with permanent structure and adjacent tubes Piece matches.
Preferably, the shape in the ramp is two ramps of L shape and same plane layer about central symmetry;The step The head and the tail connection in the adjacent ramp of upper and lower level in S5, each layer ramp, which is connected, is integrally formed two screw type running lanes.
Preferably, passenger lift well is connected with vertical shaft in the step S6.
Compared with prior art, beneficial effects of the present invention:
(1) it being excavated by the multilayer that lower space can be realized in two vertical shafts, vertical shaft is both the starting well and received well of shield, Later period also has both multiple functions, to save as the active well and the channel for connecting two L shape ramps for building vertical shaft partition Build the waste on time caused by multiple vertical shafts, fund and labour;
(2) underground space is taken full advantage of, especially unsuitable large area excavates the regions such as road, the park on ground;
(3) entire parking lot is built using mechanization, and construction efficiency is high, safety is good;
