Abstract
The utility model discloses a split starting shield tunneling machine and solves the problem that shield starting construction cannot be performed normally since the length of a shield shaft is limited is solved. The split starting shield tunneling machine comprises the shield shaft (3) arranged on one side of a pre-dig tunnel (9), a shield tunneling machine head (2), a slag conveying belt (4) and a slag box (5) are arranged in the shield shaft (3), the shield tunneling machine head (2) is connected together with the slag box (5) through the slag conveying belt (4), a shield tunneling machine control part (1), a slag box hoist gantry crane (6) and a slag pit (7) are arranged on the ground above the mouth of the shield shaft (3), the shield tunneling machine control part (1) is connected together with the shield tunneling machine head (2) through a hydraulic pipeline and an electric control line (8), the slag box hoist gantry crane (6) is arranged on one side of the slag box (5), and a hook of the slag box hoist gantry crane (6) is connected together with the slag box (5). The split starting shield tunneling machine is especially suitable for being used under the condition that the area for digging of the shield shaft is limited.
Description
Technical field
The utility model relates to a kind of shield machine, particularly a kind of shield machine starting in split mode.
Background technology
The excavation of subway tunnel generally has two kinds of patterns, and a kind of mode is Mining Method, and another mode is shield method.If the subway tunnel of construction is in complex geologic conditions and the intensive situation of above ground structure, be generally to adopt shield construction tunnel.Shield method is a kind of construction method of carrying out tunnel entirety driving with shield machine and corollary equipment thereof.Shield launching is a series of set-up procedures before shield machine construction.First, be at the end in pre-driving tunnel excavation shield structure well, the length of shield structure well generally will reach 80-100 rice, then, shield machine entirety is put into shield structure well, last, starts to carry out tunneling construction.In the situation that construction surrounding enviroment are limited, the length that the shield structure well of excavation can occur cannot meet the requirement of normally starting of shield machine, causes shield launching work progress to carry out.
Summary of the invention
The utility model provides a kind of split shield machine that starts, and has solved the technical problem that shield structure well length limited causes shield launching work progress normally to carry out.
The utility model is to solve by the following technical programs above technical problem:
A kind of split shield machine that starts, comprise pre-driving tunnel, a side in pre-driving tunnel is provided with shield structure well, in shield structure well, be provided with shield machine head, dregs feed belt and slag case, shield machine head links together by dregs feed belt and slag case, on the ground above the well head of shield structure well, be provided with shield machine control section, slag case lifting straddle truck and slag collecting pit, shield structure control section links together by fluid pressure line and electrical control circuit and shield machine head, slag case lifting straddle truck is arranged on a side of slag case, suspension hook and the slag case of slag case lifting straddle truck link together.
In shield structure well, be provided with the return pressure strengthening system of shield machine.
The utility model can reduce the excavation area of shield structure well effectively, has saved construction cost, has shortened the construction period.Particularly by increase return pressure strengthening system and slag case in the shaft bottom of shield structure well, what ensured that shield machine split starts normally carries out.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated:
A kind of split shield machine that starts, comprise pre-driving tunnel 9, a side in pre-driving tunnel 9 is provided with shield structure well 3, in shield structure well 3, be provided with shield machine head 2, dregs feed belt 4 and slag case 5, shield machine head 2 links together by dregs feed belt 4 and slag case 5, on the ground above the well head of shield structure well 3, be provided with shield machine control section 1, slag case lifting straddle truck 6 and slag collecting pit 7, shield structure control section 1 links together with shield machine head 2 by fluid pressure line and electrical control circuit 8, slag case lifting straddle truck 6 is arranged on a side of slag case 5, suspension hook and the slag case 5 of slag case lifting straddle truck 6 link together.
In shield structure well 3, be provided with the return pressure strengthening system of shield machine.
The shield machine split work progress that starts is as follows: complete after shield structure well 3 at excavation, first, shield machine head 2, dregs feed belt 4 and 5 handlings of slag case are arrived to down-hole, and connect with ground shield machine control section 1 by fluid pressure line and electrical apparatus control circuit 8.After all devices Installation and Debugging complete, start the tunneling construction in pre-driving tunnel 9.Slag case lifting straddle truck 6 by the driving slag handling in slag case 5 to ground and be poured in slag collecting pit 7.
