Abstract
The utility model relates to an FP two-dimensional composite board which is mainly applied to water resistance and drainage of mountain tunnels. The composite board comprises a high-density polyethylene (HDPE) waterproof film, a non-woven fabric, a drainage mesh core and a non-woven fabric filtering layer. The HDPE waterproof film and the surface layer of the non-woven fabric compositely form a composite waterproof layer, the surface layer of the drainage mesh core and the bottom layer of the non-woven fabric are tightly composited in a hot melting mode, and the bottom layer of the drainage mesh core and the non-woven fabric filtering layer are tightly composited in a hot melting mode. The drainage mesh core is formed by a vertical bar and oblique bars respectively arranged at the surface portion and the bottom portion, and can quickly drain underground water in the tunnels. The composite board is provided with a pore maintenance system, integrates filtering effect of geotechnical cloth, drainage effect of a two-dimensional mesh core and waterproof effect of a high-polymer waterproof film, and has complete functions of filtering, drainage and water resistance of the mine tunnels.
Description
Technical field
The utility model belongs to the tunnel water proofing field, especially relates to a kind of FP two dimension composite plate that integrates waterproof, draining, three kinds of functions of filtration.
Background technology
Existing tunnel water proofing material is generally the tunnel water proofing plate; The tunnel water proofing plate can only play single waterproof action; Often be prone to produce the space and ponding between first lining in tunnel and the splash guard, the high hydraulic pressure that ponding produces can also damage splash guard and inner lining structure and produce percolating water in the time of seriously.And the anti-drain bar of existing tunnel has only water discharging part from material structure, and anti-water section is actually a kind of single adrainage material, because this material compression strength is low, easy deformation when receiving high hydraulic pressure has a strong impact on drain function, makes the tunnel produce percolating water.
The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned technology, and the FP two dimension that integrates waterproof, draining, three kinds of functions of filtration composite plate is provided.
In order to solve the technical problem of above-mentioned existence; The technical scheme that the utility model proposes is: a kind of FP two dimension composite plate; Comprise draining web-roll core 3, be respectively equipped with nonwoven, be i.e. nonwoven 2 and nonwoven filter course 4 on draining web-roll core 3 two sides; Nonwoven 2 is provided with HDPE waterproof membrane 1, it is characterized in that: described HDPE waterproof membrane 1, nonwoven 2, draining web-roll core 3, nonwoven filter course 4 are arranged in order hot melt and are combined into one.
A kind of FP two dimension composite plate comprises draining web-roll core 3, is respectively equipped with HDPE waterproof membrane 1 and nonwoven filter course 4 on draining web-roll core 3 two sides, it is characterized in that: described HDPE waterproof membrane 1, draining web-roll core 3, nonwoven filter course 4 are arranged in order hot melt and are combined into one.
The material of said waterproof membrane 1 and draining web-roll core 3 is high density polyethylene (HDPE)s, and the material of nonwoven 2 and nonwoven filter course 4 is polypropylene fibre resins.
Said draining web-roll core 3 is the netted two-dimensional structures that are made up of one group of parallel rib and two groups that are bonded in its upper and lower surface respectively tilting parallel ribs.
Said draining web-roll core 3 is the netted two-dimensional structures that are made up of one group of parallel rib and one group that is bonded in its arbitrary surface tilting parallel rib.
Said composite plate thickness is 5.0～7.0mm, and draining web-roll core 3 thickness are 3.0～5.0mm, and HDPE waterproof membrane 1 thickness is 1.0～1.2mm, and nonwoven 2 is 200～300g/m with nonwoven filter course 4 mass area ratios
2
The advantage of the utility model FP two dimension composite plate is:
1. the utility model composite plate is with waterproof, draining, filtering integral.
2. the utility model composite plate adopts two-dimentional geotechnological web-roll core draining, and displacement is big, and draining is rapid.
Draining geotechnique web-roll core is to have adopted two-dimensional structure; High tensile strength and shearing strength; Can bear the compression load that reaches 2000KPa anti-pressure ability much larger than the normal discharge net; It is unreasonable because of constructing to have solved traditional adrainage material preferably, and compression strength is not enough, and easy deformation influences the defective of draining when under pressure.
4. the utility model composite board material is soft, can comply with the tunnel uneven laying of lining just.Composite plate self has the hole maintenance system, and with filter course, reduces the probability that geotextile embeds web-roll core, the permanently effective operation of protection drainage system.
5. the utility model composite plate resist chemical performance is excellent, can resist the corrosion from concrete and underground buck, and antimicrobial preferably bacterium infringement is arranged, and is mould proof, corrosion-resistant.

Fig. 2 is the draining web-roll core schematic three dimensional views of the utility model;
Wherein: 1, waterproof membrane; 2, nonwoven; 3, draining web-roll core; 4, nonwoven filter course.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further elaboration in detail:
As shown in Figure 1, FP two dimension composite plate comprises HDPE waterproof membrane 1, nonwoven 2, draining web-roll core 3, nonwoven filter course 4 four parts.HDPE waterproof membrane 1 is compounded to form watertight composition with nonwoven 2 hot melts.Draining web-roll core 3 upper surfaces and nonwoven 2 bottom hot melts are compound, and draining web-roll core 3 lower surfaces and nonwoven filter course 4 hot melts are compound.
The structure of draining web-roll core 3 shown in Figure 2 is the netted two-dimensional structures that are made up of one group of parallel rib and two groups that are bonded in its upper and lower surface respectively tilting parallel ribs.
This FP two dimension composite plate thickness is 5.0mm, and draining web-roll core thickness is 3.0mm, and HDPE waterproof membrane thickness is 1.0mm, and the nonwoven mass area ratio is 200g/m
