Abstract
The invention discloses a construction method for preventing temperature deformation and leakage in glass fiber reinforced mortar sewage pipelines. The method includes: covering a pipeline to prevent temperature deformation, applying AJ302 concrete re-pouring agent to the foundation of an inspection chamber to guarantee tightness of the foundation of the inspection chamber, wrapping pipe joints and the pipeline with resin for leakage prevention, and subjecting the sewage inspection chamber and the sewage pipeline to tightness test by a plugging tight fitting composed of steel plates and an air bag. Practice in multiple projections shows that the method is simple and feasible, water tightness succeeds at a higher rate, urban soil pollution is relieved effectively, finishing after engineering construction is reduced, construction period is shortened, and benefits of enterprises are increased.
Description
Technical field
The present invention relates to a kind of municipal drainage pipeline construction method, specially refer to the anti-temperature of a kind of glass reinforced plastic sand pipe sewage conduct and become the seepage job practices.
Background technology
The chemical building material sewage conduct is used more and more widely in the municipal drainage engineering, but chemical building material pipelines such as glass reinforced plastic sand pipe, HDPE pipe are subjected to influence of temperature change big, produce temperature deformation, tubing interface position, tubing and manhole connecting portion are because temperature deformation easily produces seepage, and it is qualified that the pipeline installation quality is difficult to.
Summary of the invention
For overcoming the deficiencies in the prior art, it is reasonable to the invention provides a kind of construction technology, prevents temperature deformation, reduces cost, the cost-effective job practices of fiberglass sand inclusion municipal drainage pipeline of reduction of erection time.
The objective of the invention is to realize in the following manner:
The anti-temperature of a kind of glass reinforced plastic sand pipe sewage conduct becomes the seepage job practices, it is characterized in that: adopt the covering pipeline to prevent temperature deformation, manhole uses the AJ302 concrete to water agent again to guarantee that manhole is at the seal of basic part at basic part, interface tube, pipeline antiseep adopt resin to assure processing, use steel plate and air bag combination shutoff to hold one's breath and detect harness to sewage manhole and the experiment of soil pipe seal; Its concrete construction technology process is: and preparation of construction → measurement unwrapping wire → channel excavation → based process → pipeline laying → tube chamber backfill → tight test → seepage treatment → chute builds by laying bricks or stones → and mouth of pipe connection → well chamber builds by laying bricks or stones → closed-water test → trench backfill → inspect for acceptance.
Its main technique step is:
1) sewage conduct is carried out the pipeline felt and cover, reduce the distortion of the temperature difference generation that illumination produces vitreous building materials sewage conduct, easy construction, cost are low;
2) manhole uses the AJ302 concrete to water agent again at basic part, checks that namely the borehole wall and basic part, glass reinforced plastic sand pipe junction smear one deck AJ302 concrete and water agent again, with the seal of assurance manhole at basic part;
3) tubing and manhole connecting portion carry out roughening treatment to pipeline earlier, brush interfacial agents, sewage conduct and structure be connected employing " intermediary's method " way, when pipeline is two rubber ring interface, the form that to lay rubber ring that is connected with structure, backfill has early reduced pipeline and because of the pipeline that backfilling compaction causes the leakproofness seepage phenomenon that distortion causes has been installed;
4) with the shutoff of steel plate and the air bag combination harness of holding one's breath sewage manhole and sewage conduct are carried out the seal experiment, improved the effect of closed-water test;
5) test method(s) of holding one's breath is searched the breakthrough of sewage conduct, adopts glass reinforced plastic sand pipe mouth of pipe resin to assure treatment technology, breakthrough is in time handled, thereby stopped the seepage of sewage conduct early, has reduced the environment pollution to soil property.
The invention has the beneficial effects as follows: the present invention waters agent again with admixture AJ302 concrete in the processing mortar of traditional manhole basic part and guarantees that manhole is at the seal of basic part, change traditional spacious groove construction and cover to prevent the pipe temperature distortion for felt, traditional asbestos mortar Processing Interface is improved to resin assures, change traditional closed-water test and be the test of holding one's breath, effectively reduction of erection time.Through facts have proved of a plurality of engineerings, method is simple, feasible, improved the success rate of watertightness, effectively reduce city soil property environment pollution, reduce the finishing process after the engineering construction simultaneously, shortened the construction period, increased the benefit of enterprise, good social benefit and economic benefit are arranged, promotional value is arranged in municipal engineering construction.Job practices of the present invention should be used in the urban road improvement project, and in the city was engineered, construction period height, pipeline closed water requirement height especially, adopted when adopting conventional construction party to be difficult to reach duration and quality requirement.
The specific embodiment
With reference to the specific embodiment method of the present invention is done following detailed explanation.
The specific embodiment
1, sewage conduct carries out the pipeline felt and covers, and reduces the distortion of the temperature difference generation that illumination produces vitreous building materials sewage conduct, and easy construction, cost are low.
2, manhole uses the AJ302 concrete to water agent again at basic part, checks that namely the borehole wall and basic part, glass reinforced plastic sand pipe junction smear one deck AJ302 concrete and water agent again, with the seal of assurance manhole at basic part.
3, tubing and manhole connecting portion carry out roughening treatment to pipeline earlier, brush interfacial agents.Sewage conduct and structure be connected employing " intermediary's method " way, when pipeline is two rubber ring interface, with the form that to lay rubber ring that is connected of structure, backfill early, reduced pipeline and because of the pipeline that backfilling compaction causes the leakproofness seepage phenomenon that distortion causes has been installed.
4, with the shutoff of steel plate and the air bag combination harness of holding one's breath sewage manhole and sewage conduct are carried out the seal experiment, improved the effect of closed-water test.
5, the test method(s) of holding one's breath is searched the breakthrough of sewage conduct, adopts glass reinforced plastic sand pipe mouth of pipe resin to assure treatment technology, breakthrough is in time handled, thereby stopped the seepage of sewage conduct early, has reduced the environment pollution to soil property.
Key technology: the glass reinforced plastic sand pipe sun-proof produces temperature and becomes; Water agent again with the AJ302 concrete and guarantee that manhole is at the seal of basic part; Sewage conduct and structure be connected employing " intermediary's method " way, reduce pipeline and because of the pipeline that backfilling compaction causes the leakproofness seepage phenomenon that distortion causes be installed; The shutoff of steel plate and the air bag combination harness of holding one's breath is carried out the seal experiment to sewage manhole and sewage conduct; Resin is assured the processing seepage.
Technical indicator: pipeline, manhole water percolating capacity reach code requirement.
The scope of application: job practices of the present invention is applicable to the glass reinforced plastic sand pipe sewage conduct construction in the urban road drainage engineering.
