Abstract
The invention discloses an anti-bending drainage channel for soft soil drainage consolidation. The anti-bending drainage channel comprises a telescopic drainage pipe. A drainage channel is arranged in the telescopic drainage pipe. The outer surface of the telescopic drainage pipe is wrapped with a filtering permeable layer. The telescopic drainage pipe is composed of a plurality of sections of pipe bodies. The pipe bodies are provided with drainage screen holes. Each section of pipe body is composed of a fixed part and a telescopic part. The fixed parts are arranged to be drainage hard pipe bodies bonded with the filtering permeable layer. The telescopic parts are arranged to be soft pipe bodies connected with the drainage hard pipe bodies. The anti-bending drainage channel is reasonable in design, in the drainage channel draining process, bending due to sedimentation of the surrounding soil body cannot happen, smooth drainage is ensured, and the drainage capability is greatly improved; and the anti-bending drainage channel is suitable for drainage consolidation of reclamation sludge foundations, industrial mud residues, sludge and other soft soil.
Description
Technical field
The present invention relates to a kind of weak soil discharging consolidation drainage channel, particularly a kind of blowing-filling sludge ground stabilization drainage channel.
Background technology
Reclamation engineerings a large amount of in recent years is constantly carried out, and generally adopts vacuum preloading discharging consolidation to carry out blowing-filling sludge ground stabilization, and the main plastic draining board that adopts is as drainage channel at present.Because blowing-filling sludge initial aqueous rate is high, be usually greater than 100%, cause deflection (compression ratio) very large, cause plastic draining board to bend, drainability declines greatly.Similar situation is there is in a lot of industrial slag mud, mud etc. in discharging consolidation.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of weak soil discharging consolidation drainage channel of anti-bending.
Technical problem to be solved by this invention is achieved through the following technical solutions, the present invention is a kind of weak soil discharging consolidation drainage channel of anti-bending, be characterized in: comprise telescopic drain, drainage channel is set in telescopic drain, the external surface of telescopic drain is enclosed with filtration pervious layer, described telescopic drain is made up of some pipe joint bodies, body is provided with draining sieve aperture, every pipe joint body is formed by fixed part and pars contractilis, described fixed part is set to water discharging hard pipe, and described pars contractilis is set to the flexible pipe connected with water discharging hard pipe.
Described filtration pervious layer has the effect of permeable gear mud, and as geotextiles etc., especially non-woven geotextile is better.
Invent technical problem to be solved to be realized further by following technical scheme, described flexible pipe is the corrugated flexible hose being provided with two bellows segment.
Invent technical problem to be solved to be realized further by following technical scheme, described filtration pervious layer is nonwoven fabric layer.
Invent technical problem to be solved to be realized further by following technical scheme, described some pipe joint bodies are set to one.
Invent technical problem to be solved to be realized further by following technical scheme, the aperture of described draining sieve aperture is 2-3mm, and hole ratio is 10-30%.
Invent technical problem to be solved to be realized further by following technical scheme, the length of described every pipe joint body is 1.2-2.1cm, and outer tube diameter is 2.8-3.0cm.
Invent technical problem to be solved to be realized further by following technical scheme, the linkage section connected with plastic drain is at least provided with in one end of telescopic drain, the length of described linkage section is 10-15cm, and the external surface of linkage section is provided with the anti-skidding rib in some roads.
Some pipe joint bodies of telescopic drain of the present invention are all be made up of fixed part and pars contractilis, make drainage channel around the soil body sedimentation time compress simultaneously, instead of to bend, solve the bending problem of plastic draining board.There is linkage section at least one end of telescopic drain, therefore can overlap with plastic draining board and use.
When processing full degree of depth blowing-filling sludge, all use above-mentioned telescopic drain; Be blowing-filling sludge on upper strata, lower floor is when being the soft base of deposition consolidation for many years, adopt combined water drain passage, i.e. upper strata blowing-filling sludge telescopic drain, the soft base of lower floor's deposition consolidation for many years adopts plastic draining board.
Compared with prior art, the present invention is reasonable in design, and drainage channel is in drainage procedure, can not bend because of the sedimentation of surrounding soil, guarantee that draining is unobstructed, improve drainability greatly, be applicable to the discharging consolidation of the weak soils such as blowing-filling sludge ground, industrial slag mud, mud.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Detailed description of the invention
Referring to accompanying drawing, further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
With reference to Fig. 1, a kind of weak soil discharging consolidation drainage channel of anti-bending, comprises telescopic drain 5, and telescopic drain 5 is circular, and outer tube diameter is 3cm, and its inside is set to drainage channel.The external surface of telescopic drain 5 wraps up cementing have filter pervious layer 1, filter pervious layer 1 be nonwoven fabric layer, energy permeable gear mud.
Described telescopic drain 5 is made up of some pipe joint bodies, and the length of every pipe joint body is 1.5cm, and some pipe joint bodies are set to one, and usually by PE, PP plastics material, one-time cast-forming is made.Body is provided with draining sieve aperture, and the aperture of draining sieve aperture is 2mm, and hole ratio is 10-30%.Every pipe joint body is formed by fixed part 3 and pars contractilis 4, described fixed part 3 is set to the water discharging hard pipe cementing with filtering pervious layer 1, and length is 0.5cm, and described pars contractilis 4 is set to the flexible pipe connected with water discharging hard pipe, filter pervious layer 1 cementing with the external surface of flexible pipe, length is 1.0cm.Flexible pipe is the corrugated flexible hose being provided with two bellows segment.When the sedimentation of drainage channel surrounding soil, the flexible pipe of every pipe joint body is compressed, and filters that pervious layer 1 is flexible also can be compressed along with hose compression, thus body can not bend.
When processing full degree of depth blowing-filling sludge, all use above-mentioned telescopic drain 5.Be blowing-filling sludge on upper strata, lower floor is when being the soft base of deposition consolidation for many years, adopt combined water drain passage.I.e. upper strata blowing-filling sludge telescopic drain 5, the soft base of lower floor's deposition consolidation for many years adopts plastic draining board.Therefore be at least provided with the linkage section 2 connected with plastic drain in one end of telescopic drain 5, the length of described linkage section 2 is 10-15cm, and the external surface of linkage section 2 is provided with the anti-skidding rib in some roads.During use, plastic draining board is connected with the linkage section 2 of telescopic drain 5, carry out colligation and fix.
