Description
Technical field
It the utility model is related to Water Resources Domain, more particularly to a kind of outer grouting and reinforcing servicing unit of calvert below dam pipe.Can be wide
It is general to be applied to wear the outer slip casting repairing and reinforcement of dam culvert pipe, municipal subsoil drain etc. underground pipe under water conservancy dykes and dams.
Background technology
China's water conservancy industry small reservoir enormous amount to be reinforced, most of medium and small reservoirs were built in last century five
In the sixties, by the utilization of many decades, long-term lacking maintenance, calvert below dam is caused variety of problems generally occur and lack
Fall into.At present, the culvert pipe larger to cross dimensions, because personnel can enter operation, anti-seepage reinforcing or structural strengthening are carried out to it
It is relatively easy to.Personnel can not or be hardly entered with the less culvert pipe of cross dimensions of operation, in order that it recovers original function,
It is general to have two methods of excavation and no-dig technique.Due to costly, segment length during construction, the old and new's dam body is not easy to be well combined, and digs
Open earthing culvert pipe is partially or fully removed to the method for reconstruction and very use less, and take the recovery technique pair of not excavating earth surface as far as possible
The culvert pipe of damage is partly or wholly repaired.Conventional non-excavation repairing technique mainly has grouting in soil mass method outside pipe, office in pipe
The embedding reinforcing method in portion, local inner sleeve be around-France, local liner, cured in place liner, helix tube liner, short tube and section of jurisdiction liner, in traction
Lining and undercoating method etc.；It can be divided into Anti-leakage and reinforcement structure type by purpose is repaired；By repair coverage can be divided into auxiliary repair,
Three major classes of local route repair and overall reparation；It can be divided into outside pipe by treatment site in repairing and managing and repair.
Different industries pipeline, its normal function are all identicals, i.e. the various fluids of smooth delivery of power；But its loading characteristic and should
The principal risk situation fought off is variant.For oil, chemical industry, natural gas, municipal water supply pipeline etc., in pipeline
Pressure mainly prevents the fluid media (medium) of conveying from pipe wall crack to pipe outward leakage far above outer ground water pressure and soil pressure is managed；And
Underground Culvert and municipal drainage pipeline under water resources dam or dyke, manifold pressure very little or for without pressure gravity stream, pipeline master
The outer ground water pressure of pipe and soil pressure are undertaken, mainly prevents the outer underground water of pipe to be managed through position the defects of pipe wall crack, hole
Constantly it is pulled away with current in outer soil body fine grained band inlet pipe, causes the outer soil body cavity of pipe increasing, cause dykes and dams or ground
Seepage failure collapses.The especially calvert below dam of water resources dam, managing outer soil body fine grained and constantly being taken away by infiltration will jeopardize greatly
Dam safety, its harm are bigger.It is additionally, since the outer groundwater pressure of the pipe significantly larger than municipal administration that the calvert below dam of water resources dam undertakes
Drainpipe so that the method that can apply to reinforcement culvert under water conservancy dykes and dams is greatly limited.
At present, the Dam Foundation Strengthened in Situ method applied to reinforcement culvert under water conservancy dykes and dams, widely accepted only set lined steel pipe
Method.It is high to cover lined steel pipe self-strength, can independently undertake the outer ground water pressure of pipe and soil pressure, and effectively prevents to manage outer soil body fine grained
In band inlet pipe.But set lined steel pipe once run into culvert pipe bending deformation or local faulting of slab ends, it is raised when, easily stuck, steel pipe is contained with former
The filling and injecting slurry in the gap between pipe be not easy it is closely knit, when culvert pipe is longer more so, to have bending or non-circular pipeline, steel pipe socket lining
Rule is at all at one's wit's end.To major diameter culvert pipe, once had drilled in inwall to pipe outside grouting in soil mass to reinforce culvert pipe in one's early years
Case, because operating personnel can enter, to through wall defects enter pipe in grout be also easy to clear up.This method is abundant
Make use of now injecting paste material it is very more, grouting construction process and pipeline defect location and highly developed favourable of detection technique
Condition, various injecting paste materials and construction can be correspondingly easily adjusted according to being reinforced pipeline section tube wall and manage outer soil mass property
Technological parameter, and the reinforcement and strengthening of bearing strength impervious to tube wall and the outer soil body of pipe is conveniently realized, reaches the anti-of design requirement
Ooze or intensity index, and suitable for the arbitrary cross-section shape of Underground Culvert, the anti-Seepage and structure of any number of occurrence add
Gu.But for the unapproachable medium-small diameter culvert pipe of a large amount of personnel, avoided due to can not find effective method always outside pipe
Grouting serous fluid enters in pipe through culvert pipe crack causes culvert pipe to block, therefore to grouting and reinforcing side outside the pipe of medium-small diameter defect culvert pipe
Method can not be applied always.
Utility model content
The purpose of this utility model is the defects of existing for prior art, there is provided a kind of outer grouting and reinforcing of calvert below dam pipe
Servicing unit, remains the various advantages of the outer slip casting method of pipe, while effectively prevent slurries again and enter through culvert pipe crack in pipe and make
Into the shortcomings that blocking.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions：
A kind of outer grouting and reinforcing servicing unit of calvert below dam pipe, including pressure source, in addition to connecting cylinder and flexible pipe, connecting tube
One end is tightly connected with pressure source, and the connecting tube other end passes through the closure for being arranged on connecting cylinder one end to be connected with connecting cylinder, even
Valve is provided with adapter, flexible pipe one end is openend and the other end is blind end, and the openend sealing of flexible pipe is set in connection
Cylinder the other end and fixed by clip；Spool is provided with the inside of closure, drawstring one end is on spool, the other end
It is connected in flexible pipe with the blind end of flexible pipe；Pressure gauge and atmospheric valve are provided with connecting cylinder.
A kind of outer grouting and reinforcing servicing unit of calvert below dam pipe, in addition to pull rope, pull rope through intend reinforcing pipeline section with
The blind end connection of flexible pipe.
A kind of outer grouting and reinforcing servicing unit of calvert below dam pipe, the cross section girth of described flexible pipe outer surface is not less than plan
Reinforce the cross section girth of pipe segment inner surface.
The utility model has the advantages that relative to prior art：
1st, it is simple in construction, it is easy to use.
2nd, slurries when carrying out consolidation by grouting outside culvert pipe using various grouting process are fundamentally avoided to alter into culvert pipe
Internal phenomenon, it can be widely applied under water conservancy dykes and dams wear slip casting outside the various pipelines such as dam culvert pipe, municipal subsoil drain and repair
It is added with solid.Smaller to culvert pipe internal diameter, damaged scope is larger or more serious, manages the outer soil body and is lost in more situation, its superiority is outstanding
Its is notable.
