Abstract
The combined shield consists of three (or more) subshields, each subshield is structure-like steel box body comprised of upper and lower shells, side shell, progressive hydraulic jack and pressing jack; the side shell has pressing jack which can push the adjacent subshields forward alternately, owing to the progression of individual shield in turn, the whole shield moves forward, need not depend the tunnel lining ring as recoil seat, the remainded space at tail part due to progression can be lined by using integrated reinforced concrete lining.
Description
The invention belongs to the civil engineering facility, mainly should be in the tunnel excavation 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 the reinforced concrete segment of the system of giving assembled or adopt cast-in-place steel fiber reinforced concrete, another kind is a hard rock mole, general no shield, adopt fixedly body of cross binding, do not adopt lining cutting, construction of tunnel for geology diversity and polytropy, the most of many shield configuration formulas (also claiming composite shield) of function that adopt of its excavator, the tunnel still adopts and gives system reinforced concrete segment prefbricated tunnel lining, with the back seat that advances as shield structure body, reaction force when advancing because of shield structure body is big, and needing the lining cutting ring to reach after the some could be long with shield structure body activity duration of promoting comprehensively as back seat, the shield structure body very flexible of advancing, bulky, the cost height, adopt the water proofing property difference and the globality of section of jurisdiction prefbricated tunnel lining not enough, thereby exist not enough.
Purpose of the present invention provides a kind of arranged type composite automatic progressing shield, be arranged in a combination by the sub-shield structure more than three or three, adjacent sub-shield structure can advance mutually, advancing, flexibility is good, volume is little, do not need to utilize lining cutting as back seat, thereby can adopt whole reinforced concrete lining layer, and waterproof and good integrity, thus the deficiency of existing shield structure body solved.
Narrate structure of the present invention below and advance principle certainly.
Fig. 1 is a structure chart of the present invention.
Fig. 2 is a structure section view of the present invention.
Fig. 3 is a permutation and combination schematic diagram of the present invention.
See Fig. 1,2, the sub-shield structure (A) that the present invention includes by three (or more than three) is arranged in a combination, and three shield structures all are the identical sub-shield structures (A) of structure, represents respectively with (A1), (A2), (A), sub-shield structure (A) is a casing, makes of steel material and makes. Include upper casing (4), lower casing (5), side shell (6), side shell (7), the oil that advances pushes up (1), (2) and compress oil top compositions such as (3), the upper and lower in side shell (6) is separately installed with the oil that advances and pushes up (1), advances Oil top (1) can advance the sub-shield structure of an adjacent side (A2) to advance; Upper and lower at side shell (7) is equipped with respectively the oil top (2) of advancing, and the oil top (2) of advancing can advance the sub-shield structure (A1) of an adjacent side to advance; Be separately installed with compression oil top (3) in the upper and lower half of side shell (6), have corresponding compression oil top chute (8) in the upper and lower half of side shell (7), the core bar on compression oil top (3) can be mobile in compressing oily top chute (8); Front end at upper casing (4) is equipped with pin (9), backplate (10) is equipped with in the rear end, under the protection of backplate (10), can pour into the integral reinforced concrete lining cutting, and the housing of sub-shield structure (A) is all made with steel material. When sub-shield structure is arranged combination, the side shell that sub-shield structure is equipped with the oil top (1) of advancing is equipped with adjacent the linking to each other of side shell that the oil that advances pushes up (2) with another sub-shield structure, and two adjacent sub-shield structures are strained on available tension oil top (3), a plurality of sub-shield structures are all arranged the combination (see figure 3) by this principle, arrange according to the needs of the sectional area size in tunnel and with sub-shield structure and to be combined into big sub-shield structure colony, be i.e. big shield structure body.
Narrate below the principle of advancing voluntarily of the present invention:
Fig. 1 represents the shield structure body that is arranged in a combination by three sub-shield structures (A1, A2, A), advancing of shield structure body advanced one by one, the method of advance of sub-shield structure (A1) is: sub-shield structure (A2) is strained on the oil top (3) that compresses of sub-shield structure (A), start the preceding oil-feed top (2) of sub-shield structure (A), then sub-shield structure (A1) can be advanced a distance.The method of advance of sub-shield structure (A) is: the oil top (3) that compresses that compresses oil top (3) and sub-shield structure (A1) of sub-shield structure (A) is unclamped, start the preceding oil-feed top (1) of sub-shield structure (A1) and the preceding oil-feed top (2) of sub-shield (A2), sub-shield structure (A) can be advanced a segment distance.The method of advance of sub-shield structure (A2) is: with tension oil top (3) the tension sub-shield structure (A) of sub-shield structure (A1); start the preceding oil-feed top (1) of sub-shield structure (A); then sub-shield structure (A2) can be advanced a segment distance; thereby whole shield structure body (A; A1; A2) just advance a segment distance; utilize the sub-shield structure propelling in adjacent both sides dynatron shield structure like this and utilize two to strain the method that the sub-shield structure that links to each other advances the sub-shield structure of an adjacent side by compressing oil top (3); can reach the purpose that single sub-shield structure advances one by one; thereby realize that whole shield structure body is from advancing; cycle operation so repeatedly; shield structure body moves forward and digs when into length reaches a steel concrete sections length; in the space under the protection of backplate (10); can carry out whole reinforced concrete lining layer; lay waterproofing course; main mould; assembling reinforcement; behind the fluid concrete, shield structure body can continue again to dig into.
Advantage of the present invention is simple in structure, each sub-shield structure body volume is little, in light weight, easy, the convenient transportation of processing and manufacturing combination, shield structure body is highly sensitive, it is changeable to press tunnel planform combination, compliance is strong, both can be used to excavate subway interval or station, also can be used for municipal sewage system, tunnel, communication cable culvert.
