Description

Integrated anti-drainage plate for foundation trench

Technical Field

The utility model belongs to the technical field of the railway roadbed, especially, relate to drainage bar is prevented to foundation ditch integral type.

Background

The water content of the railway subgrade is a key factor causing deformation of the subgrade and influencing the running safety of trains and the transportation efficiency of the railways, so that the problems of water prevention and drainage of the subgrade must be considered in the railway construction process. The waterproof function is to prevent the underground water of the roadbed from rising into the roadbed substrate; the drainage is to discharge the water content of the roadbed caused by natural rainfall in time.

According to the actual needs, an efficient and reliable waterproof and drainage product is required to be developed, so that the underground water of the roadbed can be effectively prevented from entering a roadbed matrix; meanwhile, the naturally rainfall ground water can be discharged in time. And in the field installation operation process, the operation is simple, and the sealing is reliable.

Therefore, the invention of the foundation groove integrated water-proof and drainage plate is very necessary.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a drainage plate is prevented to foundation ditch integral type uses in railway roadbed and roadbed basis joint portion, can high-efficient, reliable prevent the drainage, can effectively cut off roadbed groundwater and do not get into the roadbed base member, can in time discharge natural rainfall's ground water to on-the-spot installation operation easy operation, it is sealed reliable.

The foundation trench integrated water-drainage preventing plate comprises a water-drainage preventing plate, a supporting and fixing belt and geotextile which are sequentially arranged from bottom to top; the upper part of the supporting and fixing band is adhered to the geotextile and used for fixing the geotextile, and the lower part of the supporting and fixing band is connected with the upper part of the waterproof and drainage plate in an embedded manner.

Furthermore, the both sides of geotechnique's cloth are provided with the clamp plate that prevents geotechnique's cloth sticks up the limit.

Still further, prevent that the both sides of drain bar are provided with the joint tenon formula spread groove of mutual matching.

Furthermore, the waterproof and drainage plate is made of modified PVC materials through one-step extrusion molding.

Compared with the prior art, the beneficial effects of the utility model are that: the waterproof and drainage plate is used for cutting off the rising of underground water and discharging natural rainfall, the geotextile is used for keeping roadbed soil particles from losing in the drainage process, keeping the safety of a roadbed structure and preventing the drainage channel of the waterproof and drainage plate from being blocked, the supporting and fixing belt is used for adhering and fixing the geotextile and supporting the waterproof and drainage plate water tank from falling under the vertical load pressure, so that the water flowing section is not reduced, and efficient and reliable waterproof and drainage are ensured; the mutually matched tenon type connecting grooves are arranged on the two sides of the drainage preventing plates for spliced clamped connection, so that the defects that the adjacent drainage preventing plates are in adhesive lap joint due to the adoption of an adhesive, the installation operation is complex, and the adhesive is difficult to be uniformly coated during adhesion, so that the sealing is not perfect, and much underground water is turned into a roadbed matrix are overcome; the waterproof drain board is formed by adopting the modified PVC material through one-time extrusion molding, is supported by the supporting and fixing belt in an auxiliary mode, ensures that the waterproof drain board does not deform after bearing vertical load, ensures that the drainage section does not change, and ensures that the drainage rate is not reduced.

Detailed Description

The invention is further described below with reference to the accompanying drawings:

example (b):

as shown in the attached drawings 1 to 2, the foundation trench integrated water-drainage preventing plate comprises a water-drainage preventing plate 1, a supporting and fixing belt 2 and geotextile 3 which are sequentially arranged from bottom to top; the upper portion of the supporting and fixing band 2 is adhered to the geotextile 3 and used for fixing the geotextile 3, the lower portion of the supporting and fixing band 2 is connected with the upper portion of the waterproof and drainage plate 1 in an embedded mode, and a water passing groove 5 is formed in the waterproof and drainage plate 1. The water-proof and drainage plate 1 is used for preventing the groundwater from rising and draining natural rainfall; the supporting and fixing belt 2 is used for sticking and fixing the geotextile 3 and a water trough 5 for supporting the waterproof and drainage plate 1, so that the water trough is not toppled under the vertical load pressure, and the water passing section is not reduced; the geotextile 3 is used for keeping roadbed soil particles from losing in the drainage process, keeping the safety of the roadbed structure and preventing the drainage channel of the drainage preventing plate 1 from being blocked. Both sides of geotechnique's cloth 3 are provided with and prevent that geotechnique's cloth 3 from sticking up clamp plate 4 on limit, can prevent effectively that geotechnique's 3 cloth from sticking up the limit. The two sides of the water discharge preventing plate 1 are provided with the tenon type connecting grooves 6 which are matched with each other, when the water discharge preventing plate 1 is installed, the tenon type connecting grooves 6 arranged on the two sides are used for carrying out assembled type clamping connection, and the problems that due to the adoption of an adhesive, the adjacent water discharge preventing plates 1 are in adhesion and lap joint, the installation operation is complex, the adhesive is difficult to be uniformly coated during adhesion, the sealing is not perfect, and much underground water is turned into a roadbed base body are solved; prevent drain bar 1 for the disposable extrusion molding of modified PVC material, supplementary with the support of support and fixation area 2, guaranteed that prevent drain bar 1 does not have the deformation after bearing vertical load, the drainage section does not have the change, and the effective drainage sectional area of unit width reaches 3118.5mm2, and the section drainage rate reaches 40%, guarantees that the drainage rate does not reduce. Meanwhile, due to the adoption of the modified PVC, the flexibility is improved, and the fluctuation and settlement change of the roadbed foundation can be adapted.

When the utility model is installed, firstly, after the excavation of the roadbed foundation is finished, simple leveling and compacting are carried out, and the foundation trench integrated water-proof and drainage plate is perpendicular to the line direction and is tiled on the foundation surface; then, through the clamping tenon type connecting grooves arranged on the two sides of the water-proof and drainage plates, two adjacent water-proof and drainage plates are mutually clamped through the clamping tenon type connecting grooves; finally, filling the roadbed filling in layers according to the design requirements of the railway roadbed.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention.
