Abstract
The invention relates to a process for constructing a shield rapid inspection shaft. The process includes the following steps that firstly, a lock catch ring beam with steel bars reserved at the bottom is constructed; secondly, expanding excavation of a vertical shaft is carried out according to the standard that the vertical included angle of expanding excavation surfaces is smaller than or equal to 45 degrees; thirdly, the shaft body of the vertical shaft is constructed, wherein the retaining wall of the vertical shaft is formed by steel bar gratings and concrete in an anchoring and shotcreting mode and is 300 mm in thickness, and the steel bar gratings are connected with the reserved steel bars of the lock catch ring beam; fourthly, an ingate is constructed in the vertical shaft, wherein the arch-crown-gate-type ingate is constructed on the vertical shaft side wall along the tunneling axis of a shield; fifthly, the bottom of the vertical shaft is sealed through a steel bar truss to be prevented from hunching. The process for constructing the shield rapid inspection shaft is suitable for shield inspection shaft construction under various geological and hydrologic conditions, thereby bringing convenience to inspection of the shield under the shaft. The shield inspection shaft has the advantages of being safe and stable in structure, flexible in space layout, convenient to construct and operate, high in construction speed, small in occupied area and the like.
Description
[technical field]
The present invention relates to a kind of building structure and construction method thereof, be specifically related to a kind of shield structure inspection-pit and modularization construction process thereof.
[background technology]
Carry out Shield Tunneling under the geological conditions of large particle diameter sand gravel and the large erratic boulder of part time, cutterhead wearing and tearing certainly will be serious.Maintenance cutterhead, cutter if shield structure does not open a position, construction can not be carried out smoothly.
The maintenance that opens a position in hole is a kind of way wherein, but risk is also larger.And as adopted ground excavation staple, can make to overhaul Risk Reduction, meanwhile, vertical shaft can expand inner diameter volume, increases work efficiency, and accelerates inspection speed.
Therefore,, for solving the problems of the technologies described above, necessary a kind of shield structure inspection-pit and the modularization construction process thereof of providing, to overcome described defect of the prior art.
[summary of the invention]
For addressing the above problem, the first object of the present invention is to provide a kind of construction technology that is applicable to the shield structure Quick overhaul well of constructing under all geological hydrology conditions.
The second object of the present invention is to provide little, the well-set shield structure of a kind of perforate scope inspection-pit.
For realizing above-mentioned the first object, the technical scheme that the present invention takes is: a kind of construction technology of shield structure Quick overhaul well, and it comprises following processing step: 1), the construction of snap close collar tie beam, at the bottom of snap close collar tie beam reserved steel bar; 2), vertical shaft digs: the standard that is not more than 45 ° to dig the vertical angle of face digs; 3), vertical shaft well bore construction: vertical shaft retaining wall adopts reinforcing bar grid to add concrete shotcrete, and the thickness of retaining wall is 300mm; The reserved steel bar of described reinforcing bar grid and snap close collar tie beam is connected firmly; 4), horse-head ingate in vertical shaft: apply arching roof door type ingate on the vertical shaft sidewall of shield driving axis; 5), vertical shaft back cover: at reinforcing bar Pin frame back cover for silo bottom, protuberance at the bottom of control well.
The construction technology of shield structure Quick overhaul well of the present invention is further: the reserved steel bar of described reinforcing bar grid and snap close collar tie beam adopts and is welded to connect.
The construction technology of shield structure Quick overhaul well of the present invention is further: before the construction of snap close collar tie beam, need ground to carry out grouting and reinforcing.
For realizing above-mentioned the second object, the technical scheme that the present invention takes is: a kind of shield structure inspection-pit, and it comprises the snap close collar tie beam, vertical shaft well bore and the vertical shaft back cover that set gradually from top to bottom; On described vertical shaft well bore, be furnished with reinforcing bar grid; Be provided with vault door type ingate in described vertical shaft well bore sidewall.
Compared with prior art, the present invention has following beneficial effect: the construction technology of shield structure Quick overhaul well of the present invention is applicable to the shield structure inspection-pit construction under all geological hydrology conditions, thereby has facilitated the maintenance of Suporting structure in down-hole; Meanwhile, this shield structure inspection-pit has that structural safety is stable, grasp flexibly in space, convenient construction operation, and speed of application is very fast, take the advantages such as ground is less.
