For the ease of describing the present invention rather than requiring that the present invention with specific azimuth configuration and operation, therefore must be not construed as
Limitation of the present invention.
Refer to Fig. 1 and combine refering to shown in Fig. 2 to Fig. 5, the present invention provides a kind of single line Mining Method subway tunnel inclined shaft
Enter the processing method in positive hole, the method includes：
First, construct in the position that must pass through adjacent to positive hole 20 by 10 section of usual inclined shaft (such as Fig. 3).Specially：Inclined shaft
10 is to accelerate positive 20 construction progress of hole and the auxiliary equipment that is, and including the inclined shaft wall 11 based on semicircle gate-shaped, inclined shaft wall 11
The technological forming combined with secondary lining 112 using preliminary bracing 111, and semicircle arch wall 12 and connection arch wall can be divided into
12 two ends and symmetrical left and right side wall 13,14, and respectively with facing upward that left and right side wall 13,14 bottoms (mark) are connected
Arch wall 15.When opening up inclined shaft 10, be premised on accelerating 20 construction progress of positive hole, therefore, the selection of 10 entrance of inclined shaft is with which
Be easy to deeply to positive hole 20 and on the basis of accelerating the position that positive hole 20 is constructed, in embodiments of the present invention, inclined shaft 10 relative to
Positive hole 20 is formed with the section 30 (such as Fig. 1 and Fig. 2 and Fig. 5) that crosses, when inclined shaft 10 construct it is neighbouring cross section 30 when, inclined shaft wall 11 is left,
Right bottom (mark) still keeps horizontal-extending, now extends the left and right bottom included by neighbouring cross section and the section 30 that crosses
It is connected with flat wall 16, while the height (h) of the inclined shaft wall 11 included adjacent to the section that crosses extends best friend in a progressive way with wide (w)
Remittance section 30,11 height (H) of inclined shaft wall in the section that crosses 30, wide (W) standard are：The height (H) of its inwall 113 and wide (W) equal to or it is big
The height (h) of 11 periphery 114 of inclined shaft wall and wide (w) before extension.In embodiments of the present invention, inverted arch wall 15 and 16 phase of flat wall
Even, the height which connects left and right bottom respectively is highly identical with 16 plane 161 of flat wall, in the present embodiment, crosses neighbouring
Inverted arch wall 15 is replaced with flat wall 16 in section and the section 30 that crosses, its 16 plane 161 of flat wall is horizontal plane, inverted arch wall 15 is faced upward
Arch face 151, height of the inverted arch face 151 less than horizontal plane 161.
2nd, in inclined shaft 10, corresponding positive hole 20 opens up new section 31 (such as Fig. 1 and Fig. 3), wherein new section 31 is at least one
Place, its deep direction can be straight-through positive hole.Specially：Construct to Zheng Dong edges, inclined shaft 10 is closed using headwall, and aligns hole
20 implement preliminary bracing using benching tunnelling method construction, carry out positive hole 20 secondary lining using lining trolley when gradually advancing.
3rd, new section 31 is after front or construction is constructed in positive hole 20 and positive hole is constructed while construction, specially：Inclined shaft
After the completion of 10, in the intersection 30 of design, (namely on the left and right side wall 13,14 of inclined shaft wall 11) correspondence is just wide open digs new
Section 31, the construction of new section 31 can be parallel with the construction of positive hole, also can carry out before the construction of positive hole or after construction.Thereby account for
The technical problem of (new and old) multibreak surface construction, so as to accelerate construction progress, is effectively shortened the duration.As positive hole is to adopt
Conventional benching tunnelling method or other auxiliary service markets are constructed, and construction the design focal point of non-invention in positive hole, therefore do not make in detail
Repeat.
