Abstract
The drainage plate consists of plastic core plate with drainage grooves on its two sides and filtering film forming circular coating of the core plate with the overlapped part of filtering film being adhered by adhesive. The adhesive is produced by using polyethylene acetate, rosin polymer, low molecular polythene, paraffin, antioxidant, and other material and through heating reaction, and it is spread by extruder to the connection part of filtering film and adhered by temperature controlling adhering machine.
Description
The present invention relates to construction material, be mainly used in reinforced soft soil grounds such as tidal land and desert and handle.
With plastics (as polyethylene etc.) is that raw material is made banded central layer, make filter membrane with terylene, polypropylene fibre or vinylon fibre etc. again, encase central layer by filter membrane, form band drain, insert soft foundation, underground water enters the central layer rhone through filter membrane, be used to reinforce draining, with its easy construction, advantage such as drainage effect is good is widely used.But existing above-mentioned band drain, be filter membrane to be made the fixing parcel in back with central layer by suture, therefore, there is following defective: the one, underground mud enters quilted plastic panel by the pin hole of sewing up, stop up the drainage channel of quilted plastic panel, influence the underdrainage effect of plastic draining board, reduced the actual required displacement of engineering; The 2nd, in the sewing process, the sewing machine operating personnel are difficult to accomplish that in a rhone straight line sews up, needle gage sample different in size, and the degree of tightness of parcel is inconsistent, and the combining structure of whole band drain is not reached the steady quality unified demand.
The purpose of this invention is to provide does not a kind ofly have the damage of making to band drain, avoids sludge granules to enter in the band drain, and guarantees drainage plate for reinforcing soft foundation and the band drain production method that quality is unified, reliable and stable.
The technical scheme of drainage plate for reinforcing soft foundation of the present invention is: be made up of quilted plastic panel and filter membrane, rhone is arranged on the central layer, it is characterized in that rhone is on the two sides of central layer, filter membrane has overlapping layer after central layer is wrapped up, the adhesive linkage that bonding agent is arranged between the overlapping layer filter membrane, filter membrane constitute the annular parcel of split to central layer.
The production method of drainage plate for reinforcing soft foundation of the present invention: with plastics is that raw material forms central layer, the two sides of central layer is to constitute rhone by muscle, the filter membrane parcel is arranged outside central layer, filter membrane is made by chemical fibre, it is characterized in that after filter membrane is to the central layer parcel overlapping layer being arranged, between the overlapping layer filter membrane, adhesive linkage is arranged, the bonding agent of adhesive linkage is a chemical adhesive, chemical adhesive is by acetate ethylene copolymer (EVA), newtrex, low molecular weight polyethylene, paraffin, antioxidant, dibutyl ester or dibutylester, calcium carbonate etc. are raw material, make through adding thermal response, bonding agent is by extruder coating filter membrane junction, and is bonding through the bonder temperature control again.
The production method of drainage plate for reinforcing soft foundation of the present invention, its bonding agent is that raw materials such as acetate ethylene copolymer (EVA), newtrex, low molecular weight polyethylene, paraffin, antioxidant, dibutyl ester or dibutylester, calcium carbonate are dropped into reaction pot, be heated to 60～120 ℃, reacted 3～10 hours, being heated to 70～100 ℃ during coating extrudes through extruder, be applied to the filter membrane junction, bonding by the bonder temperature control again.
The production method of drainage plate for reinforcing soft foundation of the present invention after extruder is applied to filter membrane with bonding agent, is wrapped up filter membrane by one group of Wrap device to central layer, bonding by bonder again, the bonder tack temperature is controlled at 90～110 ℃.
The present invention is a kind of drainage plate for reinforcing soft foundation and production method, by chemical adhesive filter membrane is carried out the bonding quilted plastic panel that wraps up, and makes the inartificial damage of filter membrane and central layer, avoids sludge granules to invade in the central layer.Compared with the prior art, it is good to have the involution performance, and parcel degree of tightness unanimity is not made and stayed through hole, filter membrane filtration rate height, and rhone is unimpeded, and displacement is big, guarantees workmanship, can obtain promising result.
Fig. 1 is a drainage plate for reinforcing soft foundation cross-sectional structure schematic diagram of the present invention;
Fig. 2 is drainage plate for reinforcing soft foundation filter membranous layer of the present invention and rhone schematic diagram.
Below in conjunction with Fig. 1-Fig. 2 embodiments of the invention are done detailed explanation.
The present invention relates to the band drain that area, soft basis (as tidal land, desert) reinforces, make banded central layer 1 by plastics (as polyethylene etc.), the upper and lower faces of central layer is made of the rhone 5 of a rule the muscle 2 that distributes, at central layer 1 coated outside filter membrane 4, filter is touched by the bonding agent involution and is become adhesive linkage 3, from cross section, as shown in Figure 1, filter membrane 4 circularizes, and is enclosed within the central layer outside, and both separate.Be deep to 30～40 meters because band drain (filter membrane and central layer) insertion is underground, be embedded in underdrainage again for a long time, so material needs anti-aging, performances such as acid and alkali-resistance will be got well.Filter membrane is that nonwoven fabric of synthetic fibre is made, and the bonding agent of filter membrane 4 is chemical adhesives.Produce totally 7 kinds of raw materials such as bonding agent acetate ethylene copolymer (EVA), newtrex, low molecular weight polyethylene, paraffin, antioxidant, dibutyl ester or dibutylester, calcium carbonate etc., drop into reaction pot and be heated to 60～120 ℃, reacted about 6 hours, the bonding agent that reaction is made is by a kind of small-sized extruder and be heated to about 80 ℃ and extrude.Be extruded into the junction at nonwoven filter membrane two ends, every meter band drain is pasted about 1～1.5 gram of bonding agent, and bonding through bonder, the bonder tack temperature is controlled at 95～1002, evenly pressurized adhesion output.In order to guarantee the reliability of bonding quality, at the front end of automatic bonder, the automatic Wrap device of nonwoven filter membrane 4 and quilted plastic panel is installed, make filter membrane and central layer parcel degree of tightness consistent.
