Abstract
The invention discloses a mortar pipe embedded tail shield comprising a tail shield body, mortar pipes and a hinged ring, wherein the tail shield body is made into a cylindrical thin shell; and the front end of the tail shield body is welded together with the hinged ring, and the rear end of the tail shield body is connected with a support. The mortar pipe embedded tail shield is characterized in that the mortar pipes are prepared to be clumpy. The tail shield body is slotted according to the sizes of the mortar pipes after being welded together with the hinged ring, and then the mortar pipes are welded into the corresponding slots in the tail shield body. The tail shield body is welded together with the mortar pipes in a complete penetration weld way. By using the mortar pipe embedded tail shield, the space occupied by the mortar pipes is reduced, and the gap between the tail shield and each pipe piece is also reduced, so that the quantity of the filled mortar is greatly reduced, furthermore, the construction cost is greatly reduced, the stability of a stratum is improved, and the sedimentation of the stratum can be better controlled.
Description
Technical field
The present invention relates to tunnel machine field, especially balancing earth-pressure shielding machine field, particularly relate to the embedded tail shield of a kind of mortar pipe.
Background technology
The tail shield of balancing earth-pressure shielding machine is a tubular construction part become by Plate Welding; generally be made up of tail shield body, hinge eyes, mortar pipe, greasing pipe etc.; it is connected with middle shield by bolt or hinged oil cylinder; and hinged sealing is housed, in tunneling process, play protection pipe sheet assembling, prevent swelling in stratum from entering the important function in tunnel.
Mortar pipe is the chief component of grouting at the tail of the shield machine, and the filling mortar between tail shield and section of jurisdiction all will get to tail shield rear portion by mortar pipe.
The form of the Grouting Pipe of known balancing earth-pressure shielding machine tail shield is inner convexed mostly, adopts the tail shield of the mortar pipe of this form of structure to there is following shortcoming:
1, take up room greatly;
2, greatly, easily there is sedimentation, and make grouting at the tail of the shield machine amount large when constructing in shield tail and section of jurisdiction crest clearance;
3, tail shield external diameter is large, makes whole cutterhead, anterior shield, the external diameter of middle shield also strengthens.
Summary of the invention
The object of this invention is to provide the embedded tail shield of a kind of mortar pipe, adopt that taking up room of the shield tail of inner convexed Grouting Pipe is large, grouting amount is large, tail shield external diameter is large to solve most of known balancing earth-pressure shielding machine, tail shield and gap, section of jurisdiction greatly, the shortcoming of free settling.
The embodiment of the present invention provides a kind of mortar pipe embedded tail shield, comprising:
Tail shield body, mortar pipe, supports and hinge eyes, wherein:
Described tail shield body makes cylindrical shape thin walled shell, and described tail shield body front end is welded with described hinge eyes, supports after described tail shield body described in termination;
Described mortar pipe makes bulk;
Described tail shield body is slotted according to the size of described mortar pipe after welding with described hinge eyes, to be then welded on by described mortar pipe on described tail shield body in corresponding groove;
Further, first described tail shield body is welded with described hinge eyes, then with described support and connection, and then the size of described tail shield body according to described mortar pipe to be slotted, more described mortar block is welded on described tail shield body successively.
Mortar pipeline is embedded in tail shield shield shell by the present invention, reduces the space that mortar pipeline takies, also reduces the gap between tail shield and section of jurisdiction, thus the mortar amount of filling is reduced greatly.Because the gap of filling reduces, also make the stability on stratum higher, the sedimentation on stratum can better be controlled, and greatly reduce construction cost on the basis reducing gap between tail shield and section of jurisdiction.
