Description
Technical field:
The present invention relates to positive a kind of form of structure, assembling mode, the inspection operation that injects foam of the past cutterhead of balancing earth-pressure shielding machine in the tunnel piercing technical field.
Background technology:
1), foam plays improvement quarrel soil, increases the flowability of quarrel soil at present, in the balancing earth-pressure shielding machine excavation operation, the effect of foam is in the tunnel piercing technical field:; 2), the tensile property that has of foam itself, an overfill protection tunneling prevents that the tunnel from subsiding; 3), play lubricated tool surface, alleviate the wearing and tearing of cutter and cutterhead steel construction piece toward the positive foam that injects of cutterhead.
The apparatus for spray of foam of cutterhead manufactured in the past: bore system one through hole on the steel plate in being connected of cutterhead front panel and back panel, perhaps bore system one concentric and equal-sized circular hole, steel pipe in the welding between the front of cutterhead, back panel.Cutterhead front panel through hole reprocessing one concentric counterbore, thread mill drilling in the counterbore is fixed on foam jet in the counterbore with screw then, and the hole at the cutterhead back side is connected with foam line, realizes to cutterhead front spray foam.Though this device can be realized to cutterhead excavation face spray foam, but quarrel soil, sandstone that shield machine is discharged during excavation operation forward easily wear and tear foam jet bad, if meet under the clay geology situation, easily foam jet is stopped up, thereby cause that foamite system lost efficacy.This from the positive apparatus for spray of foam form of structure of installing of cutterhead, shield machine in the hole during operation once damage and can't change.Therefore developing a kind of soil pressure balance shield machine back loading type cutter head foam injection apparatus is the new problem of being badly in need of solution both at home and abroad.
Summary of the invention:
The purpose of this invention is to provide a kind of design science novelty, at the dismounting of the cutterhead back side and the soil pressure balance shield machine back loading type cutter head foam injection apparatus that can clean, overhaul.
The object of the present invention is achieved like this: the soil pressure balance shield machine back loading type cutter head foam injection apparatus, by the cutterhead front panel, endoporus has the steel pipe of seam flange, the cutterhead back panel, the foam line box that has the sealing thread hole, sealing ring, the sleeve that has the terminal perforate of foam jet, barrier film, flange, sealing mat, the sealing and fixing plug screw, screw, foam, the excavation face, cutter is formed, the seam flange end that endoporus has the steel pipe of seam flange is connected with the cutterhead front panel, the other end is connected with the cutterhead back panel, the foam line box that has the sealing thread hole is connected with the cutterhead back panel, it is concentric with the sealing thread hole of the foam line box that has the sealing thread hole that endoporus has the steel pipe of seam flange during connection, the sleeve that has the terminal perforate of foam jet attaches together with the screw handle with barrier film and flange and is made into one, and itself and the sealing ring endoporus of packing into had in the steel pipe of seam flange, the position of opening that has the terminal perferated thimble of foam jet must be aligned with the hole that has the foam line box in sealing thread hole during assembling; The sealing mat of packing into is then tightened the sealing and fixing plug screw, and foam and water are injected on the excavation face and cutter in cutterhead front through having sealing thread hole foam line box by having the sleeve of the terminal perforate of foam jet, spraying through barrier film; Bore system one through hole on the front of cutterhead, back panel, the steel pipe that endoporus is had the seam flange is connected in the cutterhead through hole; When connecting steel pipe, the flanged seam end of steel tube inner hole is connected cutterhead front panel end and maintains a certain distance with the cutterhead panel; The cutterhead back panel connects the foam line box have the sealing thread hole, the sealing thread hole be connected the steel tube inner hole that endoporus on the cutterhead has a seam flange and align; The barrier film mount is having nozzle and terminal having on the sleeve that leads to foam and water; The purpose of perforate has two effects on the sleeve, and an effect is logical foam and water, and another effect easily splits out sleeve when being maintenance; Sleeve adopts stainless steel or nylon, PTFE material to make, in case with cutterhead on steel pipe corrosion bonding; Sleeve, sealing ring that barrier film is housed are packed into and are had in the steel pipe of seam flange, and sleeve has logical foam and water during assembling hole and pipeline box hole align, and load onto sealing mat then, tighten the sealing plug screw.
Main points of the present invention are its structure and operating principle.Its operating principle is, the soil pressure balance shield machine back loading type cutter head foam injection apparatus, by the cutterhead front panel, endoporus has the steel pipe of seam flange, the cutterhead back panel, the foam line box that has the sealing thread hole, sealing ring, the sleeve that has the terminal perforate of foam jet, barrier film, flange, sealing mat, the sealing and fixing plug screw, screw, foam, the excavation face, cutter is formed, the seam flange end that endoporus has the steel pipe of seam flange is connected with the cutterhead front panel, the other end is connected with the cutterhead back panel, the foam line box that has the sealing thread hole is connected with the cutterhead back panel, it is concentric with the sealing thread hole of the foam line box that has the sealing thread hole that endoporus has the steel pipe of seam flange during connection, the sleeve that has the terminal perforate of foam jet attaches together with the screw handle with barrier film and flange and is made into one, and itself and the sealing ring endoporus of packing into had in the steel pipe of seam flange, the position of opening that has the terminal perferated thimble of foam jet must be aligned with the hole that has the foam line box in sealing thread hole during assembling.When barrier film is changed in the needs maintenance, pull down the sealing plug screw at the back side of cutterhead, take out sealing mat and the sleeve that barrier film, flange are housed; Clean then and change; It is very convenient to operate dismounting at the back side of cutterhead, saves time, and only needs a people just can finish the maintenance disassemble and assemble work.
The soil pressure balance shield machine back loading type cutter head foam injection apparatus compared with prior art has design science novelty, in the dismounting of the cutterhead back side and can clean, advantage such as maintenance, will be widely used in the tunnel piercing technical field.
