Abstract
The invention discloses a method for conduction through an asymmetric section pile tunnel method for an urban subway station. In the process of urban subway station asymmetric section construction, water flows out of an upper-level pilot tunnel firstly and then the upper-level pilot tunnel is constructed. In the construction process, the middle portion of the upper-level pilot tunnel is N cm higher than the portions at the two sides of the upper-level pilot tunnel. In the process that the upper-level pilot tunnel is excavated and a support is constructed, water flows out of a lower-level pilot tunnel, after water completely flows out of the lower-level pilot tunnel, the lower-level pilot tunnel is excavated and a support is constructed. The portions at the two sides of the lower-level pilot tunnel are lower than the middle of the pilot tunnel. The portions at the two sides of the lower-level pilot tunnel are narrower than the middle of the pilot tunnel. The method for conduction through the asymmetric section pile tunnel method for the urban subway station is high in adaptability, small in abandoned work amount and low in cost.
Description
Technical field
The invention belongs to tunnel and underground construction technical field, be specifically related to the method for the asymmetric section stake of a kind of City Subway Station hole method construction.
Background technology
In the work progress of the tunneling " PBA " of subway station, domestic city employing at present engineering method, mostly construct according to the sequence of construction of this engineering method routine and design drawing, especially still require difficulty of construction very big according to this engineering method routine meeting under adverse geological condition or complicated ambient environmental conditions, not in time to design section be optimized cause follow-up difficulty of construction greatly and abandoned project amount more.
Summary of the invention
The object of the invention is to overcome the shortcoming of above-mentioned prior art, the method for the asymmetric section stake of a kind of City Subway Station hole method construction is provided, the method can strong adaptability, and abandoned project amount is few, and cost is low.
For achieving the above object, the method of the asymmetric section stake of City Subway Station of the present invention hole method construction adopts stake hole method to carry out in the process of City Subway Station asymmetric end surface construction, first carry out the precipitation of upper strata pilot tunnel, then carry out the construction of upper strata pilot tunnel, in work progress, by the high Ncm of height of the aspect ratio both sides pilot tunnel of middle pilot tunnel in the pilot tunnel of upper strata; In to the process of upper strata pilot drive and supporting construction, carry out the precipitation of lower floor's pilot tunnel, after reaching anhydrous condition, lower floor's pilot tunnel precipitation carries out again excavation and the supporting construction of lower floor's pilot tunnel, wherein, in lower floor's pilot tunnel, the height of both sides pilot tunnel is less than the height of middle pilot tunnel, and in lower floor's pilot tunnel, the width of both sides pilot tunnel is less than the width of middle pilot tunnel.
N equals 70.
The present invention has following beneficial effect:
The method of the asymmetric section stake of City Subway Station of the present invention hole method construction is in the process of construction, first carry out the precipitation of upper strata pilot tunnel, carry out again the excavation of upper strata pilot tunnel, in to the process of upper strata pilot drive, carry out the precipitation of lower floor's pilot tunnel, after reaching precipitation condition, the precipitation of lower floor's pilot tunnel can carry out the excavation of lower floor's pilot tunnel, in the middle of simultaneously in the pilot tunnel of upper strata, the height of pilot tunnel is higher than the height of both sides pilot tunnel, can effectively increase the height between back and pilot tunnel top, be beneficial to the construction of girder construction, in addition, in lower floor's pilot tunnel, the height of both sides pilot tunnel and width are all less than height and the width of middle pilot tunnel, effectively improve the safety of both sides pilot tunnel in excavation and supporting stage, reduce abandoned project amount, reduce engineering cost.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
With reference to figure 1, the method of the asymmetric section stake of City Subway Station of the present invention hole method construction adopts stake hole method to carry out in the process of City Subway Station asymmetric end surface construction, first carry out the precipitation of upper strata pilot tunnel, then carry out the construction of upper strata pilot tunnel, in work progress, by the high Ncm of height of the aspect ratio both sides pilot tunnel of middle pilot tunnel in the pilot tunnel of upper strata; In to the process of upper strata pilot drive and supporting construction, carry out the precipitation of lower floor's pilot tunnel, after reaching anhydrous condition, lower floor's pilot tunnel precipitation carries out again excavation and the supporting construction of lower floor's pilot tunnel, wherein, in lower floor's pilot tunnel, the height of both sides pilot tunnel is less than the height of middle pilot tunnel, and in lower floor's pilot tunnel, the width of both sides pilot tunnel is less than the width of middle pilot tunnel.
N equals 70.
Obviously, described embodiment is only the present invention's part embodiment, instead of all; Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of protection of the invention.
