Description

Pipeline non-excavation rehabilitation pretreatment bracing members system

Technical field

The utility model relates to a kind of support system in pipeline rehabilitation Study on pretreatment field, particularly a kind of pipeline non-excavation rehabilitation pretreatment bracing members system.

Background technique

Cities and towns water supply and sewerage pipeline is the important component part of Municipal facility, is again simultaneously the underground life line in city, and it bears the discharge function of the supply of tap water and rainwater, sewage.Along with the expansion of urban size, the construction speed of pipe engineering and scale also reach unprecedentedly high level, and the pipeline mileage of such as GuangzhouCity center district reaches 1297.495km.Along with expanding economy, the scale of urban construction is increasing, and the drainage pipe of laying is also more and more longer, and pipeline is also shorter and shorter for remaining service life.Since two thousand one China's urban discharging pipeline is with the speed of 22441.7km/ in increase according to statistics, and the total length of cut-off China's urban discharging pipeline in 2008 is 315220km.Along with the construction of China's drainage pipe, lay pipeline of the remote past and also in succession reach lifetime.The duct length that China laid the eighties in the past is according to statistics 21860km, accounts for 6.93% of drainage pipe overall length.China's drainage pipe face the life-span overdue while, along with the increase of urban water consumption, municipal drainage amount is corresponding reinforcement mouth also, the load that drainage pipe bears is also more and more heavier, and China's insufficient investment in the maintenance, reparation of drainage pipe, cause China's drainage pipe corruption candle, seepage serious, pipeline damage, distortion, the uneven situations such as sedimentation that hook happen occasionally.Pipeline configuration defect and functional defect cause drainage pipe can not play due effect, and rainwater runs, emits, leaks, and block traffic, rainwater can not be got rid of in time, makes troubles to urban construction and people's lives.When 2010 " 5.7 ", liang field, " 5.14 " Guangzhou, rainfall rate is more than the cloudburst of 100mm, many streets, retail shop, parking lot etc. meet with water I, economic loss surpasses 1,000,000,000 yuan, has appeared the problem of drainage pipe impeded drainage suddenly.

The traditional remodeling method of drainage pipe is that excavation lays a new pipeline, but because drainage pipe is generally all laid in urban district that is populous, business prosperity, tube circumference fills other municipal pipeline and the facilities such as sewage, rainwater, coal gas, heating power, electric power, communication cable, ride above part pipeline and press against building or be crushed on completely below road, therefore improvement project implements to there is sizable difficulty.For addressing this problem, no-dig technique pipe rehabilitation technology is applied and gives birth to.Trenchless sewer repair technique is as the new and high technology of development in recent years, and this technology has the features such as construction site is little, construction is simple, avoid the generation of the phenomenon of similar roadbed subsidence or large size water, cost is lower, is widely applied.Pipeline spray repair method is a kind of process engineering representative in non-excavation repairing technique, and the method is applicable to the pipeline of the Large Diameter Pipeline of more than 800mm or the in-situ immobilization of canal case.The method is as sprayed on material using epoxy resin, by the rotary nozzle under the effect of winch pulling force or manual method, material is sprayed successively in old pipeline or canal case, form certain thickness back-up coat, form pipeline-lined compound pipe, reach the entirety reparation to old pipe or canal case.This technology can improve the withstand voltage, corrosion-resistant of pipeline and abrasion resistance properties, extends pipeline or canal case life-span.But the spraying reparation of large pipeline or canal case needs operator to operate in inside, the personal safety of structural instability to operator of pipeline or canal case constitutes titanic peril; If pipeline to be repaired or canal case are positioned at level of ground water higher position, will occur seriously to ooze, leak, have a strong impact on the quality that spraying is repaired; Before the spraying of under ground piping or canal case is repaired, generally all to carry out pretreatment to pipeline or canal case, preprocessing process generally all can adopt the machineries such as percussion drill, electric planer, grinder to process tube wall, and the stability that pipeline or the vibrations of canal inner box-machine tool will destroy pipeline or canal case causes part to cave in.

Drainage pipe pretreatment for structural disease generally adopts method such as polishing cutting, slip casting soil stabilization, pad repairing material etc., and this method is used in pipeline and less mismatch or diafiltration occur, and inapplicable for the pipeline seriously caved in.And at present good preprocess method is not also had to the big-diameter pipeline caved in.At present for this kind of situation, the main cut and cover method that adopts adopts new pipeline to replace by occurring that the pipeline section seriously caved in digs out.Although this method easy construction, cost are lower, construction is considered carefully very fast, are only limitted to open space, traffic flow is less, other pipeline is less, away from the area of building.And at major urban arterial highway, due to large, the various pipeline of traffic flow be interspersed, road periphery tall building stands in great numbers, particularly disease tube circumference in old town generally has more heritage building, just cannot carry out trenchless rehabilitation in this case, original position pretreatment must be carried out in underground to pipeline and recover its pipe shape for non-excavation rehabilitation condition is provided.
