Detailed description of the invention
Below in conjunction with specific embodiment and accompanying drawing, the present invention is described in further detail.The example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining technical scheme of the present invention, and not should be understood to limitation of the present invention.
In describing the invention, term " interior ", " outward ", " longitudinal direction ", " transverse direction ", " on ", D score, " top ", " end " or "front", "rear", "left", "right" etc. instruction orientation or position relationship be based on orientation shown in the drawings or position relationship, be only the present invention for convenience of description instead of require that the present invention with specific azimuth configuration and operation, therefore must not should be understood to limitation of the present invention.
Referring to Fig. 1 and combining consults shown in Fig. 2 to Fig. 5, and the invention provides the processing method that a kind of single line Mining Method subway tunnel inclined shaft enters positive hole, the method comprises:
One, to construct the position must passed through in contiguous positive hole 20 by usual inclined shaft 10 section (as Fig. 3).Be specially: inclined shaft 10 is the supporting facility being for accelerating positive hole 20 construction progress, and the inclined shaft wall 11 comprised based on semicircle gate-shaped, the technological forming that inclined shaft wall 11 adopts preliminary bracing 111 to combine with secondary lining 112, and semicircle arch wall 12 can be divided into and connect arch wall 12 two ends and symmetrical left and right side wall 13,14, and the inverted arch wall 15 be connected with (mark) bottom left and right side wall 13,14 respectively.When offering inclined shaft 10, to accelerate premised on the construction progress of positive hole 20, therefore, the selection of inclined shaft 10 entrance is for benchmark with its position being easy to deeply also can accelerate to positive hole 20 construction of positive hole 20, in embodiments of the present invention, inclined shaft 10 is formed with the section of crossing 30 (as Fig. 1 and Fig. 2 and Fig. 5) relative to positive hole 20, when the vicinity section of crossing 30 constructed by inclined shaft 10, inclined shaft wall 11 is left, right bottom (mark) still keeps horizontal-extending, now extend the left side that the contiguous section of crossing and the section of crossing 30 comprise, right bottom is connected with flat wall 16, the height (h) of inclined shaft wall 11 that the vicinity section of crossing comprises simultaneously extends to the section of crossing 30 in a progressive way with wide (w), inclined shaft wall 11 height (H) in the section of crossing 30, wide (W) standard is: height (H) and wide (W) of its inwall 113 are equal to or greater than the height (h) and wide (w) of expanding front inclined shaft wall 11 periphery 114.In embodiments of the present invention, inverted arch wall 15 is connected with flat wall 16, its height connecting left and right bottom is respectively highly identical with flat wall 16 plane 161, in the present embodiment, inverted arch wall 15 is replaced with flat wall 16 in the contiguous section of crossing and the section of crossing 30, its flat wall 16 plane 161 is horizontal plane, and inverted arch wall 15 has inverted arch face 151, and inverted arch face 151 is lower than the height of horizontal plane 161.
Two, in inclined shaft 10, new section 31 (as Fig. 1 and Fig. 3) is offered in corresponding positive hole 20, and wherein new section 31 is at least a place, and its deep direction can be straight-through positive hole.Be specially: construct to Zheng Dong edge, adopt headwall close inclined shaft 10, and align hole 20 adopt benching tunnelling method construct implement preliminary bracing, when advancing gradually adopt lining trolley carry out positive hole 20 secondary lining.
Three, newly section 31 is constructed in positive hole 20 front or constructs after constructing and the while of construct in positive hole, be specially: after inclined shaft 10 completes, 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, new section 31 is constructed and can be constructed parallel with positive hole, also can carry out before the construction of positive hole or after construction.Solve the technical problem of (new and old) multibreak surface construction by this, thus accelerate construction progress, effectively shorten the duration.Because positive hole adopts conventional benching tunnelling method or the construction of other auxiliary service market, and the construction in positive hole not design focal point of the present invention, be not therefore described in detail.
