And the bracing or strutting arrangement of existing section of jurisdiction secondary lining equipment comprises a pole, support boots are symmetrically arranged with at the side of a pole, a pole is provided with propelling cylinder and props up pole, this section of jurisdiction secondary lining equipment is lived first lining cutting tunnel wall by the support stretcher for boot and shoe of a pole is advanced to provide enough frictional force to order about equipment.Because the tunnel segment structure intensity of first lining cutting is more weak, be not enough to fastening advance, and the tunnel by using the scheme of large support boots easily to damage first lining cutting in progradation, and at scraggly tunnel surface, the discontinuity supportting boots can be caused, affect the advance of equipment; In addition, in tunnel, weak area, easily damages the tunnel of first lining cutting.
Summary of the invention
Technical problem to be solved by this invention is that the deficiency existed for above-mentioned prior art provides that structure is simple, do not damage the internal expansion type counter-force bracing or strutting arrangement for section of jurisdiction secondary lining equipment on tunnel inner wall surface in work progress.
The technical solution adopted in the present invention is: a kind of internal expansion type counter-force bracing or strutting arrangement for section of jurisdiction secondary lining equipment, comprise a pole, the shield frame circumference of a pole is provided with multiple propelling cylinder, it is characterized in that the sidewall circumference of the shield frame of a pole is provided with multiple air bag, on each air bag, correspondence is provided with entrance and outlet, described entrance and exit is connected with gasbag pressure control system, described gasbag pressure control system for adjusting the pressure size in air bag, from making air bag swell and reducing.
By technique scheme, when in air bag during tensioner, its external surface protrudes corresponding shield frame sidewall.
By technique scheme, be provided with two groups and prop up pole, be respectively first pole and second pole, first propelling cylinder of first pole is connected with the shield frame of second pole, second propelling cylinder rear end of second pole is corresponding with segment assembly, and on each pole, correspondence is provided with air bag.
By technique scheme, the shield frame of first pole and second pole is a meter shaped girder steel, on in the middle part of the girder steel that described first propelling cylinder is arranged on first pole, and be connected with in the middle part of the girder steel of second pole, each second propelling cylinder is disposed on the periphery circumferential position of second pole.
By technique scheme, be installed with air bag deck in the sidewall circumference of each pole, described air bag is installed in air bag deck.
By technique scheme, the pressure limit in each air bag is: 500MPa ~ 1000MPa, and the sidewall circumference of each pole is provided with 16 ~ 36 air bags.
By technique scheme, when being filled with air, gasbag pressure control system is pneumatic control, and when being filled with liquid, gasbag pressure control system is hydraulic control, and wherein liquid can be water or other liquid.
Beneficial effect acquired by the present invention is: the present invention is by arranging some air bags in the shield frame sidewall circumference of a pole, air bag is made to hold out against tunnel inner wall by interior tensioner air bag, thus the frictional force required for equipment advance is provided, make tunnel inner wall border uniform force, avoid the destruction of the first trimmed tunnel caused due to rigid support, and be suitable for the scraggly tunnel of inner surface; When arranging two groups and propping up pole, by regulating the size of intracapsular pressure, two poles are moved ahead alternately, and during tubulature sheet, two internal expansion type counter-forces being propped up pole and all working, and can provide and be greater than 2 times of axial forces, strong adaptability, bend, large tunnel can be adapted to.
