Description
The invention belongs to technical field with the method for concrete field fabrication pipeline.The technology of not having the method for seam, the underground gas transmission that tightness is good, the concrete duct of infusing specifically with the concrete field fabrication.
We build large-scale water delivery, gas transmission engineering pipeline now, all be after cement product precast plant makes, to transport concrete duct to job site more in advance, carry out pipe laying, because the whole piece pipeline is to be formed by connecting with successively a pipeline, each pipe joint road makes already, therefore there are many joints in the whole piece pipeline, and joint, every pipe joint road adopts cement to smear seam more, bituminous sand slurry is smeared, or adopt the rubber cushion rubber to push method connections such as leak stopping, but no matter connect, all can not solve the leakage problems at pipeline joint-seam place with the sort of method leak stopping.And every water saving mud pipeline is in the process of making, be with the steam rapid solidification of heating, thereby the quality of pipeline is had a greatly reduced quality.It is 86107919 that Patent Office of the People's Republic of China discloses an application number on June 15th, 1986, name is called the patent application of " spot continual construction method for concrete pipeline ", its disclosed technology is to spread watertight plastic film or the soft thing of other watertight thin type in the groove that digs, lay half rib shape shop slurry mould, can inject the concrete that stirs in the slurry mould of shop descends segment pipe to build, the Lower Half pipeline has been built and has been taken out shop slurry mould, putting the steel pipe internal mold into vibrates, thereafter take out the steel pipe internal mold and put inflatable airtight flexible pipe inflation again into, charge gas, on flexible pipe, buckle the punching block of band material feeding mouth, grave mound, flexible pipe is extracted in venting then out, and a section concrete pipeline can be built and be finished in general 40 minutes, carried out building of next section again.Must stay one section flexible pipe in the concrete pipe of having built when carrying out the building of next section; Build reinforced concrete pipiline as need, directly assembling reinforcement skeleton on plastic pellicle of having completed or watertight soft thing replaces circle rib shape shop slurry mould with Framework Of Steel Reinforcement, directly builds the Lower Half concrete duct after the colligation, and other technology is the same.Though this technology discloses a kind of technology that seems to be the in-situ continuous pouring concrete duct, but one, this technology is the casting craft of pipeline Lower Half in fact, and does not build the technology of the first half, behind the grave mound, whether with material feeding mouth punching block just do not wanted, perhaps it is the part of pipeline, if it is a mould, and the taking-up that it will be complete, open soil again after injecting concrete, can only take out the punching block outer wall, how that takes out the punching block inwall, and we are unknown.Two, it is too big to open native workload behind the grave mound again, and labor intensity is too high, if the punching block inwall does not take out, the both has increased the cost of pipeline greatly.If take out the punching block inwall by force, certainly will inner-walls of duct will be damaged.Three, in groove, lay plastic pellicle or the soft thing of watertight thin type, also improve the cost of pipeline greatly.Be placed with half rib shape shop slurry mould when four, Lower Half is built; then extract half rib shape shop slurry mould again out and put into the steel pipe mould; when the injection concrete vibrates; because concrete characteristic; not having weight to be pressed on the steel pipe mould or with the steel pipe mould fixes in advance; the steel pipe mould can move upward automatically, and concrete is then walked downwards, and Lower Half will be difficult to pour into semicircle.And to put shop slurry mould earlier, and starch mould with the steel pipe mould shop that swaps out again, with the airtight flexible pipe steel pipe mould that swaps out, building of lower half portion will be changed mould, trouble very three times again.Five, this technology has been built the first half, breaks ground again again, takes out punching block, this needs long time, and during this period of time concrete has passed through best freezing period, therefore, between leading portion and back segment joint is arranged, this technology does not claim it is the technology of in-situ continuous pouring concrete duct.From the International Classification of Patents of its prospectus, also be that it is sorted in E04G21/14, E04G15/00, E02B3/16, not the on-the-spot processing range of making conveyance conduit continuously yet.
