Description

The contiguous block band drain

One) technical field

The utility model relates to the band drain of a kind of underdrainage and structure draining.

Two) background technology

At present, in civil engineering, often must carry out the draining of the soil body or structure inside, as dewatering, the row's of cutting underground water, the barricade back of the body, abutment draining or the like.In these drainage workss, normally used material has rigid band drain and flexible porous tube, rigid band drain generally is to be made up of the plate outer wrapping geotextile of projection or rhone, as shown in Figure 1, its shortcoming is that band drain itself has certain degree of hardness, need in long length range, could be out of shape, needing the occasion of local distortion, regular meeting damages, therefore commensurate structure thing or change of topography preferably, especially at tunnel drainage, the pavement edge draining, occasions such as retaining wall draining, need especially a kind of whole softer, with commensurate structure thing surface appearance or change of topography, and on the part firmly to improve compressive strength and to guarantee the band drain of draining cavity; Flexible porous tube (as shown in Figure 2) is made up of steel coil outsourcing geotextiles, flexible porous tube has flexibility, can adaptation to the ground and the uneven situation of structure, but self there is following shortcoming in it, the one, because it is a tubulose, when being used on the works, infiltration in only collecting among a small circle, therefore and occupy bigger solid space, during the water on needs eliminating face, flexible porous tube usually can inefficiency; The 2nd, be provided with on the flexible porous tube and arrange warp parallel closely, significantly reduced permeable efficient, its use is very limited.

Three) summary of the invention

The purpose of this utility model is to provide a kind of local compressive strength height, can changes the contiguous block band drain that drainage efficiency is high by the commensurate structure shape.

The purpose of this utility model is achieved like this: comprise permeatable filter layer and draining central layer, it is characterized in that: the draining central layer is coupled together block by silk thread to be formed, the draining central layer plan-position changing of the relative positions that wherein single block can be formed with respect to block, and be provided with permeatable filter layer.

Described block materials can be unit of plastic, cement block, the block that stone and composite material thereof are formed.

Described block can be provided with column.

Each block of described connection can have contact mutually, also can piece and interblock the space is arranged.

After described block is connected to and forms plane tabular simultaneously, has the drainage channel of connection.

Described silk thread refers to that silk thread can become regular graticule mesh earlier, is used further on the block perpendicular to the diameter of section of length direction or cross section length of side plastics, rubber, fiber, the wire less than 2 centimetres.

Described silk thread can be arranged at and make block be connected to form the draining central layer in each block, also can be arranged on block and make each block be connected to form the draining central layer outward.

The draining central layer plan-position changing of the relative positions that described single block can be formed with respect to block can be meant that single block can be on draining central layer plane or with respect to the changing of the relative positions that certain displacement is vertically arranged on plane, with the variation of commensurate structure body or landform shape.

The material of described permeatable filter layer is a geotextiles.

Can be provided with wire loop on the described contiguous block band drain.

The central layer that described band contiguous block is formed can be superimposed together more than two.

Described contiguous block band drain can with plastic irregular profile, helical spring combination further increases the draining cavity, drainage efficiency further improves.

The utility model band drain can be provided with geomembrane according to actual conditions on several, and makes at least one face of the utility model contiguous block band drain permeable.

The utility model compared with prior art has the following advantages: 1, the good rough surface configuration of commensurate structure thing of band drain energy, the variation of adaptation to the ground; 2, it is a tabular, does not occupy bigger solid space, satisfies the demand of works flat drainage; 3, each block compressive strength height, under pressure the distortion little, thereby guaranteed enough drainage spaces; 4, drainage efficiency height.
