塑料排水板又名塑料排水带,中间是挤出成型的塑料芯板,是排水带的骨架和通道,其断面呈并联十字,两面以非织造土工织物包裹作滤层,芯带起支撑作用并将滤层渗进来的水向上排出,塑料排水板用插板机插入软土地基,在上部预压荷载作用下,软土地基中空隙水由塑料排水板排到上部铺垫的砂层或水平塑料排水管中,由其他地方排出,加速软基固结。在软土地基处理中,塑料排水板的作用设计,施工设备基本与袋砂井相同。

1、塑料排水板可在超软弱地基上进行插板施工。

2、塑料排水板滤水性好,排水畅通,排水效果有保证。

3、塑料排水板断面尺寸小,施打排水板过程中对地基扰动小。

4、材料有良好的强度和延展性,能适合地基变形能力而不影响排水性能。

5、塑料排水板施工快、工期短,每台插板机每日可插板15000m以上,造价比袋砂井低。对于深厚的软土地基采用排水固结法进行加固时,从技术上和经济上考虑,采用排水板几乎是唯一经济、有效、可行的方法。

Plastic drainage plate is also known as the plastic drainage belt, the middle is plastic core plate extrusion molding, is the skeleton and channel drainage zone, and the cross section is parallel to the cross, the two sides of nonwoven geotextile bags filter layer, the core band plays a supporting role and the filter layer permeability in water up to discharge, plastic drainage board for inserting machine is inserted into the soft soil foundation, in the upper pre load, pore water in soft soil foundation by plastic drainage plate row to the sand or horizontal plastic drainage pipe in the upper part of the upholstery, discharged from the other place, to accelerate the consolidation of soft soil foundation. In the soft soil foundation treatment effect of plastic drainage board, design, construction equipment and basically the same bag sand well.

1, the plastic drainage board can be inserted in the super soft foundation construction.

2, the plastic drainage board the filtered water is good, smooth drainage, drainage effect is guaranteed.

3, plastic drainage plate small section size, application of drainage board in the process of the foundation of small disturbance.

4, material strength and good ductility, can be suitable for the deformation of foundation and can not affect the ability of the drainage performance.

5, plastic drainage board fast construction, short construction period, each insertion machine can be inserted in a day more than 15000m, than the bag sand well in low cost. The soft soil foundation with drainage consolidation method for reinforcement, consider from economy and technology, using drainage board almost is the only way to economic, effective, feasible.
