Description
Technical field
The present invention relates to undergrounds to ooze weeper drain, and in particular to be high-speed railway subgrade substrate underground water development area
Assembled oozes weeper drain.
Background technology
In railway bed design, roadbed substrate deformation or differential settlement to solve to induce due to underground water is developed are asked
Topic generally sets longitudinal french drain to carry out ejectment to underground water, so as to reduce the underground of roadbed substrate in subgrade bed two bottom sides
Water level ensures that the stability of roadbed disclosure satisfy that High Speed Railway Trains Operational requirements.
Currently used roadbed longitudinal direction blind drainage system is mainly bis- by concrete bed, concrete reinforced pipe or HDPE
Wall corrugated drain pipe, clean rubble, permeable geotextiles and loaded filter composition, but there are several shortcomings：(1) composition material is various.
The french drain used at present is broken by cast-in-place concrete pedestal, armored concrete precast perforated pipe or HDPE double-wall corrugated pipes with holes, cleaning
Stone, permeable geotextiles and packed sand gravel loaded filter composition, material is various, and each material needs voluntarily to process without finished product
Or purchase post-processing；(2) construction cost is excessively high.Since traditional french drain employs the ejectment water pipe, clean rubble, package of punching
Permeable geotextiles and code build packed sand gravel loaded filter, and material is various, complex procedures, cause to construct cumbersome, difficulty of construction is big,
Construction efficiency is low, construction cost is high, seriously affects construction speed；(3) construction quality is uncontrollable.Due to traditional blind ditch construction work
Sequence is numerous and diverse, exposure duration is long after long construction period, excavation of foundation pit, quality testing is not perfect, causes construction quality uncontrollable, especially
Be easy to cause as reinforced concrete sewer pipe water seepage hole reserve not in place, periphery rubble isotonic water material is unqualified, loaded filter not
Reach design requirement to water seepage hole result in blockage wait construction quality problems；(4) lack french drain whole detection standard.It is although right at present
The quality testing of each component part of french drain has standard requirement, but lacks to the permeability of french drain entirety, drainage performance and pressure resistance
The examination criteria of degree.
With the continuous propulsion of China express railway construction, contradiction day of the roadbed subdrainage structure between design and construction
Benefit is prominent, and unit in charge of construction is also more apparent for the repulsion psychology of traditional french drain, and processing is bad will to give Environment in Railway Engineering Construction and work
Operation security hides some dangers for afterwards, therefore is produced there is an urgent need for developing a kind of novel weeper drain that oozes that can solve site operation contradiction
Product.
To sum up, how to design it is a kind of can solve the novel of site operation contradiction and ooze weeper drain product, become as ability
One of the problem of field technique personnel's urgent need to resolve.
Invention content
In view of the above shortcomings of the prior art, the present invention provides assembleds to ooze weeper drain, mainly solves existing french drain
Composition material is various, construction cost is excessively high, construction quality is uncontrollable, lacks the problem of french drain whole detection standard.
To achieve the above object, the technical solution adopted by the present invention is as follows：
Assembled oozes weeper drain, and including pedestal, the collector pipe being set on the base is arranged on catchment tube outer surface and position
Pervious bed in pedestal top is wrapped in the geotextiles of pervious bed outer surface and is arranged on the clathrum of geotextiles outer surface；
The outer surface at the clathrum both ends is provided with press strip, and the upper skeleton for being useful for support is uniformly arranged in the pervious bed, described
Collector pipe top, which is gathered, offers gully-hole.
Further, the tube outer surface that catchments is evenly equipped in thread groove and thread groove filled with grid.
Further, the collector pipe is provided at both ends with prevents sundries from entering the end cap in collector pipe when transporting.
Further, the collector pipe gathers in 2/3 part of top offers gully-hole.
Further, a diameter of 10mm of the gully-hole.
Further, grid is installed on the inside of the pervious bed between the upper skeleton.
Preferably, the geotextiles are long filament geotextiles.
Compared with prior art, the invention has the advantages that：
The present invention proposes that assembled oozes the concept of weeper drain, and each individual components are combined into a set of product,
Site operation can be quickly and effectively carried out behind transport to scene, construction site caused by overcoming traditional french drain composition material mostly
Store keeping is difficult, and construct Chen Bengao, the uncontrollable shortcoming of construction quality, is also adapted to now integrated to engineering modularization become
Gesture.Upper skeleton enhancing structure intensity is set to cause the present invention that can bear upper load on collector pipe of the present invention, convenient for burying, catchmented
The structural strength that slot also further enhances collector pipe is threaded outside pipe.The present invention is convenient for production to it for factory modularization
Permeability, drainage performance and compression strength carry out systematicness, comprehensive detection, effective guarantee product quality and construction quality.
Present invention reduces old of in-site installations, overcome the problems of traditional french drain, have it is quick and easy for installation, product quality is steady
Fixed, environmentally friendly durability is strong, can meet the associated specifications of roadbed underground drainage facility, quick, warp simple compared with traditional measures
Ji, and reliability is high, cannot be only used for railway bed subdrainage, it can also be used to it arranges the underground of highway subgrade or building lot
Water, market scale is huge, and popularizing application prospect is wide.
