Abstract
The present invention relates to a combination type sliding protecting plate automatic advanced shield body used for bored tunnel operations. The present invention is formed by combining a plurality of sliding protecting plate automatic advanced bodies, and each of the sliding protecting plate automatic advanced bodies is composed of a sliding protecting plate, a sliding seat and an advanced oil top. The action of the oil top can push the sliding protecting plate to slide and advance on the sliding seat, and each sliding seat can be pulled to advance, adjacent sliding seats are fastened and connected to form a shield body, and the action of the oil top can cause the whole shield body to be onwards pushed. The present invention has the advantages of simple structure, easy fabrication and combination and reliable automatic advanced performance, which is suitable for excavating subway sections or stations or city sewers or communication cable culverts.
Description
The invention belongs to a kind of tunnel support device, be mainly used in set of tunneling construction.
The development machine that the tunneling in tunnel, urban subway is adopted, a kind of is weak soil development machine (being the shield structure), it is provided with shield, lining cutting adopts prefabricated reinforced concrete segment assembled or adopt cast-in-place steel fiber reinforced concrete, another kind is a hard rock mole, general no shield, adopt and laterally walk the support fixation body, do not adopt lining cutting, construction of tunnel for geology diversity and polytropy, big of its development machine adopts the many shield configuration formulas (also claiming composite shield) of function, the tunnel still adopts prefabricated reinforced concrete section of jurisdiction prefbricated tunnel lining, with the back seat that advances as shield structure body, the reaction force that advances because of shield structure body is big, and a powerful back seat be arranged, thereby the lining cutting ring could be promoted comprehensively shield structure body as back seat after reaching some, the very flexible that shield structure body advances, cost is expensive, adopts the water proofing property difference and the globality of section of jurisdiction prefbricated tunnel lining poor, thereby exists not enough.
Known Chinese patent 94206714.2 " arranged type composite automatic progressing shield " adopts sub-shield structure to combine, and realizes advancing certainly of shield structure body by the mutual principle of propeller of sub-shield structure, but still exists sub-shield structure body long-pending excessive, advances difficult shortcoming.
The purpose of this invention is to provide a kind of combined self-advancing shield of sliding retaining-plate, combine from advancing body by a plurality of sliding shelling plates, sliding shelling plate can self-propelled, advance flexibly, resistance is few, and volume is few, combined and instant, shield structure body can advance certainly, can adopt whole reinforced concrete lining layer, thereby solves the deficiency of existing shield structure body.
Narrate structure of the present invention below and advance principle certainly.
Fig. 1 is a structure chart of the present invention.
Fig. 2 is an I-I view profile of the present invention.
Fig. 3 is an II-II view profile of the present invention.
Fig. 4 is sliding shelling plate forward travel state figure of the present invention.
Fig. 5 is combined into the shield structure body schematic diagram for the present invention.
Fig. 6 is combined into the shield structure body schematic diagram for the present invention.
See Fig. 1,2,3, the present invention is combined from advancing body by a plurality of sliding shelling plates, and each is sliding Moving backplate includes by backplate 1, slides channel-section steel 2 from advancing body, slides limiting plate 3 and piston rod The sliding shelling plate A that support 5 forms is by vertical square steel 7, horizontal square steel 6,13, spacing The sliding seat B that piece 9, oil cylinder seat support 12, roof pressure oil cylinder 8 forms and 4 of the oil cylinders of advancing Form, in sliding shelling plate A, the limit that slides that slides channel-section steel 2, two symmetries of two symmetries Position plate 3 all is welded on the beneath side of backplate 1, and piston rod support 5 reaches under being welded on backplate 1 Slide the inboard of channel-section steel 2, sliding channel-section steel 2 can be on vertical square steel 7 of sliding seat B vertically Slide. In sliding seat B, the two ends of vertical square steel 7 of two symmetries are welded on respectively laterally Inboard between the square steel 6,13, the mounting of formation sliding seat B, 12 welderings of oil cylinder seat support Connect the inboard that is fixed on horizontal square steel 13 and vertical square steel 7, in horizontal square steel 6 and 13 Be welded with above symmetrical limited block 9, slide the transverse direction that channel-section steel 2 slides with restriction, can only Longitudinally square steel 7 vertically slides, and has circular hole M above in horizontal square steel 13, laterally The roof pressure oil cylinder 8 that is equipped with in the square steel 13 can with backplate 1 roof pressure, increase backplate 1 and tunnel The frictional force on stratum, road, the seat end of the oil cylinder 4 that advances is fastened on oil cylinder seat with connecting bolt 11 On the support 12, piston rod 10 usefulness connecting bolts 11 are fastened on the piston rod support 5. Before Oil-feed cylinder 4 action live stopper rods 10 stretch out, and can promote sliding shelling plate A and advance, and Fig. 4 is for sliding When the state after moving backplate A advances, the frictional resistance on backplate 1 and stratum, tunnel are big, The oil cylinder 4 that advances moves, and piston rod 10 is retracted, and then sliding seat B can be pulled to and advance, and replys Original state, such as the location status of the sliding seat B of Fig. 1, the reciprocating action of the oil cylinder 4 that advances, Just can realize that sliding shelling plate is from advancing advancing voluntarily of body.
The present invention combines shield structure body by a plurality of sliding shelling plates from advancing body, along actual tunnel Periphery be combined into whole shield structure body (seeing Fig. 5,6), the section in tunnel can be rectangle, Also can be circular; During combination, with a plurality of sliding seat B, with bolts or be welded on Together, start one by one respectively the oil cylinder 4 that advances, sliding shelling plate A advances respectively one by one, and is all sliding After moving backplate A advanced, the oil cylinder 4 that all advances shrank back with advancing to shrink piston rod 10, then connects The sliding seat B that is connected together is pulled to and advances, and has realized that whole shield structure body advances certainly, so repeatedly Cycle operation, shield structure body are constantly mobile forward, when dig into length reach an armored concrete During sections length, can carry out the integral reinforced concrete lining cutting in the space that afterbody is vacated later, Behind the assembling reinforcement formwork erection concrete perfusion, shield structure body can move on again.
The present invention adopts steel material to make, tunnel cross-section requirement under the base area, and sliding shelling plate is from advancing backplate or the sliding seat that body can be made circular arc type.
Advantage of the present invention is that each sliding shelling plate is from advancing the simple in structure of body, the little processing and fabricating of volume is easy, reliable from the property advanced, structure size, shape need make up shield structure body under can the base area, compliance is strong, combination both can be used to excavate subway interval or station easily, also can be used for city water channel, tunnel, communication cable culvert.
