Description

The active efficient discharging water blind pipe system in underground

Technical field

The utility model relates to a kind of underdrainage system more particularly to a kind of efficient drainage systems in active underground.

Background technique

Infiltration and level of ground water due to natural precipitation rise, and lead to railway and highway subgrade water content is more than roadbed design It is required that roadbed is caused to liquefy, the road diseases such as there is subgrade frost heaving, settle, collapse, long-standing problem highway layout, construction and supporting Shield becomes the feeding persistent ailment of road dimension.

In order to solve roadbed disease as caused by problem of groundwater, the design of both sides of the road open drain is also used, But this bright ditch design can only enough solve ground and show water problems, can not solve earth's surface infiltration and water problems is developed in underground, It is palliative.

With the high speed development of high-speed railway, Railway Roadbed prevention and treatment rises to very urgent stage, Railway Design Seep weeper drain structure in the traditional underground of department's researching and designing.Such structure is by reinforced concrete sewer pipe, geotextiles and clear Graded sand and stone after washing is formed as loaded filter, and each section is supervised in the construction process by construction personnel at the scene step by step to protect Its effect is demonstrate,proved, therefore many uncontrollable factors occurs, quality is difficult to control.Due to for seep discharge structure, under normal circumstances only Subsurface rock crevice water and the bright water of soil supersaturation water can be only discharged by seepage flow mode, and due to geotextiles It uses, is ensureing that soil particle is not lost, row's soakaway trench are nonclogging to seep drainage efficiency while require and substantially reduce.In short, Just because of quality is difficult to control, drainage efficiency is difficult to ensure, weeper drain structure is seeped in traditional underground to be played a role.

Therefore traffic base construction technique field be badly in need of a kind of structure it is simple, can active discharging water, in-site installation is just Prompt, the long-acting active draining blind pipe system of reliable, quality controllable Novel underground.

Preferably, the drainpipe, active water sucting plate are all made of the disposable extrusion moulding of high density PVC, and the two uses Seamless hot melt fitting, water conservancy diversion catchments to be completed in joint, does not destroy the integrality of drainpipe, with high ring stiffness and is resisted Compressive Strength.

Preferably, the active water sucting plate is directly contacted with subsurface rock or soil, is fully phased out geotextiles, is greatly mentioned High drainage efficiency.

Preferably, the flexible joint can connect two sections of active discharging water blind pipe assemblies at a certain angle, thus Reach the requirement of any direction Small-angle Rotation, and then meets the turn curvature requirement and foundation settlement requirement of railway, highway.

Preferably, the slit pick trough is usually to be arranged, therefore completely avoid possibility along tube body longitudinal length Sub-terrain mines substance crystallization blocked caused by drainpipe.

The utility model has the beneficial effects that:

The utility model is a kind of efficiently whole suction water system in active underground, and compared with prior art, this is practical new Type has the advantages that

Using completely new structure type, by discharging water, the components such as catchment, check, forms complete underground actively Drainage system, more original single underground deep embeded type reinforced concrete sewer pipe, the utility model have it is extremely strong systematicness, Integrality.

The complete the factorial production of each component, molding assembly, quality control is reliable, avoids original underground french drain scene The quality uncontrollability of construction.

Relatively pass by the structure type for adding geotextiles soil conservation anti-blocking using the sandstone filter layer that certain gradation cleans up, The utility model is skillfully constructed, structure and its simple, only there are four the complete draining pipe assembly of components composition, low in cost, Key is to increase absorbent function, is increased to Active Drainage from single passive infiltration draining, greatly improves drainage efficiency.

Using high-intensitive engineering PVC material, there is good anti-pressure ability and flow mechanical performance, can adapt to each The uneven part sedimentation of kind ground.

In an installation, using flexible connection mode, effective solution drainpipe can not any deflecting for the utility model The problem of turning, meets small curvature turning radius (R≤500m) the automatic turning needs of high-speed railway.Simple installation simultaneously, favorably In quality control on construction and work efficiency is improved, and then substantially reduces construction cost.
