Abstract

The invention relates to a permanent blocking inclined shaft structure isolated from a tunnel. An inclined shaft is a temporary project, supporting measures are weak, and therefore the inclined shaft is prone to collapsing, and underground water leaks and can not be led out. A lining at the bottom of the inclined shaft is enhanced to serve as a permanent structure, and an inclined shaft body stone blocking wall and two blocking walls are arranged along an inclined shaft channel. A transverse well direction ditch is arranged on the upper slope toe of a first blocking wall body in an excavated mode, connected into a longitudinal well direction ditch arranged at the bottom of the wall body in an excavated mode and then connected into a transverse well direction water flowing groove formed in the lower slope toe of the wall body in an excavated mode. A longitudinal well direction water flowing groove formed along one side of the lower slope of the first blocking wall penetrates through the second blocking wall and is connected into a water flowing groove formed in the upper slope of a tunnel-entering opening of the inclined shaft in an excavated mode and connected into a side ditch in the tunnel through a longitudinal well direction drainage pipe, and finally water is drained out. The inclined shaft can be safely isolated from the tunnel, besides, the water in the inclined shaft can be drained out normally, so that structure safety of the bottom of the inclined shaft is guaranteed, and water drainage is smooth, and therefore no threat on the tunnel can be caused.

Description

Permanent shutoff inclined shaft structure with tunnel isolation
Technical field
the invention belongs to tunnel traffic field of engineering technology, be specifically related to permanent shutoff inclined shaft structure a kind of and tunnel isolation.
Background technology
The traffic engineering such as China railways, highway has been built a large amount of construction of tunnel, length and super long tunnel are for accelerating construction progress, shortening construction period, often in conjunction with landform condition setting the service galleries such as inclined shaft, Heng Dong, vertical shaft as increasing the means of work plane, and more in the majority with inclined shaft.Inclined shaft is temporary works often, only use in construction period, therefore its supporting measure relatively a little less than, construction period can be taked local stiffening measure at any time, after finishing using, long-term placement easily produces the phenomenon of caving in, falling rocks tumbles and can cause direct harm to tunnel, inclined shaft bottom, simultaneously, in general inclined shaft, all there is ground water seepage, flowing water can only flow to tunnel Zheng Dong along slope, as carry silt secretly, be easy to stop up Zheng Dong gutter, therefore, need to take a kind of appropriate plugging structure, by inclined shaft and tunnel safety isolation, water in inclined shaft normally can be drained again simultaneously, tunnel itself is threatened avoiding.
Summary of the invention
The object of this invention is to provide permanent shutoff inclined shaft structure a kind of and tunnel isolation, can, by inclined shaft and tunnel safety isolation, the water in inclined shaft normally can be drained again.
The technical solution adopted in the present invention is:
With the permanent shutoff inclined shaft structure of tunnel isolation, be provided with the inclined shaft passage of incoming tunnel, it is characterized in that:
Inclined shaft passage to the access section in tunnel arranges shaft bottom permanent lining, secondary lining and forms reinforcing section, in the inclined shaft passage of reinforcing section, is disposed with inclined shaft well bore stone cut off wall and twice block wall Zi upward slope to descending;
The upper toe of inclined shaft well bore stone cut off wall body of wall dig horizontal well to ditch, the vertical well of burying underground with body of wall bottom to gutter be communicated with;
The upper toe of first block wall body of wall dig horizontal well to ditch, this horizontal well to the vertical well that digs of ditch access first block wall body of wall bottom to ditch, this vertical well to the horizontal well that digs of ditch access first block wall body of wall descending toe to gutter channel, this horizontal well to the vertical well that arranges of gutter channel and first block wall descending one side to gutter channel be communicated with, this vertical well to gutter channel through second block wall, access inclined shaft enter tunnel mouth go up a slope the horizontal well that digs to gutter channel in, this horizontal well to gutter channel by the vertical well in this place to gutter incoming tunnel in lateral sulcus.
In the body of wall of inclined shaft well bore stone cut off wall and first block wall, be provided with vertical well to spilled water hole.
Between first block wall and second block wall on the path of gutter channel, between second block wall and tunnel, on the path of gutter channel, all dig sedimentation basin.
The ditch of first block wall and second block wall all offers inspection passage through place, and the inspection channel setting of first block wall has steel casement door.
The entrance of all spilled water holes and gutter is provided with screen pack.
The present invention has the following advantages:
The present invention is based on the existence conditions of inclined shaft, arrange one to twice block wall in inclined shaft bottom, one to two sedimentation basin, can, by inclined shaft and tunnel safety isolation, the water in inclined shaft normally can be drained again, ensure inclined shaft shaft bottom structural safety, draining is unimpeded, can not threaten to tunnel itself, well bore stone cut off wall also can keep at a certain distance away and arrange flexibly according to factors such as inclined shaft length, plurality of advantages such as having easy construction, reduce investment outlay, be safe and reliable.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention will be described in detail.
The permanent shutoff inclined shaft structure of a kind of and tunnel isolation the present invention relates to, that existing inclined shaft passage is transformed to the structure of reinforcing, comprise the inclined shaft passage of incoming tunnel, inclined shaft passage to the access section in tunnel arranges shaft bottom permanent lining, secondary lining 1 and forms reinforcing section, and the rock mass in inclined shaft passage is reinforced.In the inclined shaft passage of reinforcing section, be disposed with inclined shaft well bore stone cut off wall 5 and twice block wall Zi going up a slope to descending.
Inclined shaft well bore stone cut off wall 5 is used for tackling the Rolling Stone after inclined shaft partial collapse, avoid directly impacting the block wall of descending, the quantity of inclined shaft well bore stone cut off wall 5 can keep at a certain distance away and arrange flexibly according to inclined shaft length, the upper toe of inclined shaft well bore stone cut off wall 5 bodies of wall dig horizontal well to ditch 8, the vertical well of burying underground with body of wall bottom to gutter 7 be communicated with.
The upper toe of first block wall 4 bodies of wall dig horizontal well to ditch 8, this horizontal well to ditch 8 access vertical well that first block wall 4 bodies of wall bottoms dig to ditch 8, this vertical well to ditch 8 access horizontal well that first block wall 4 body of wall descending toes dig to gutter channel 10, this horizontal well to gutter channel 10 and the 4 descending one side settings of first block wall vertical well to gutter channel 10 be communicated with, this vertical well to gutter channel 10 through second block wall 2, access inclined shaft enter tunnel mouth go up a slope the horizontal well that digs to gutter channel 10 in, this horizontal well to gutter channel 10 by the vertical well in this place to gutter 7 incoming tunnels in lateral sulcus.
