Abstract
A plastic drainage board used for treating a soft soil base by drainaging water actively relates to a tool used for treating the soft soil base by drainage method, in particular to a drainage board that needs to be inserted into the soft soil base in order to discharge the water from the soft soil when the drainage method is used for treating the soft soil base. The utility model consists of a drying plate 1 and a filter membrane 3 that wraps the whole drying plate. The drying plate consists of a closed rectangle slot or a circular tube 5 and an open cross or parapet-shaped slot 4. The rectangle slot or the circular tube is arranged at a lower side below water and pores 6 are distributed on the rectangle slot or the circular tube at intervals, thus facilitating the entering of water from the pores. The upper end of the drainage board is connected with a pumping plant to draw up the water from the rectangle slot or the circular tube to achieve the purpose of reinforcing the soft soil base. The plastic drainage board well solves a problem that the treatment effect of the soft soil base is poor since the drainage board is used as a passive drainage channel ever for a long time. In addition, the plastic drainage board has novel design and simple structure, thus facilitating industrial production.
Description
Technical field
The utility model relates to the instrument that a kind of drainage is handled soft base, is specially to be used for the initiatively plastic draining board of draining.
Background technology
Soft soil foundations such as highway, railway, town road, storage yard, water conservancy, airport, usually adopt drainage, this method is with certain device plastic draining board to be inserted in the ground, form vertical water flowing approach, spread sand bedding course and form horizontal water flowing approach, add top preloading or vacuum preloading, make foundation soil strength increase, use very extensive to satisfy requirement of engineering.
The problem that occurs in the engineering practice is that when using preloading, existing plastic draining board is similar to collecting well as just the passage that catchments, the poor effect of passive draining; When using vacuum method, need whole treatment of soft foundation place is airtight, cost is very high, and the duration also prolongs, and the cross in the plastic draining board or parapet shape open slot usually stop up by well resistance phenomenon, can't form drainage channel preferably.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, and the drainage effect difference of existence and complex process defect of high cost aim to provide a kind of simple and cheap plastic draining board.
Technical solutions of the utility model: when adopting drainage to handle soft base, in soft base, insert the utility model, this utility model constitutes by central layer with filter membrane two parts of the whole parcel of central layer, core plate structure is rectangular channel or the pipe and the unlimited cross or the parapet shape groove composition of sealing, rectangular channel or pipe at water level with the hypomere side, the aperture of a determining deviation distributes, so that from then on moisture enter, connect water plug in the band drain upper end, take the moisture in rectangular channel or the pipe away, reach the purpose that strengthens soft base.Advantage and effect: use the utility model, solve employed for a long time band drain or poor preferably as just passive drainage effect, in conjunction with the problem of vacuum preloading cost height, complex process, novel in design unique, simple in structure, be convenient to large-scale industrialization production.

The specific embodiment
When adopting drainage to handle soft base, this utility model of this plant produced is inserted projected depth in the ground, stay a bit of exposing, cut off then, connect water plug at the cut-out section place, the operation of drawing water gets final product.
Claims (2)
1, is used for the plastic draining board that soft base is handled in initiatively draining, it is characterized in that central layer is made up of vertical lattice (1) and several lined (2), whole central layer coated outside filter membrane (3), middle and both sides are the rectangle or the circle (5) of sealing, remove cross or parapet shape notch (4) that this forms opening, at every below the water level aperture (6) that distributes on lined.
2, according to the described initiatively plastic draining board of draining that is used for of claim (1), it is characterized in that the central layer that rectangle or round sealed groove (5) and cross or parapet shape open slot (4) are formed, the aperture (6) of distribution some during it is lined.
