Description
Technical Field
The utility model belongs to the field of drainage structures, and particularly relates to a retaining wall body drainage device.
Background
The retaining wall should be provided with drainage facilities to dredge the moisture in the slope material behind the dry wall, prevent the earth's surface from oozing and causing ponding behind the wall to make the wall body avoid extra hydrostatic pressure, eliminate the expansion pressure that the cohesive soil filler produced because of the water content increases, reduce the frost heave pressure of seasonal frozen area filler. The drainage facilities of the retaining wall are generally divided into two parts, ground drainage and wall drainage.
According to design specifications, the drainage holes are arranged at proper height of the wall body according to the water seepage quantity. The range of 50cm at the water inlet of the water discharge hole should be covered by granules with reverse filtering effect.
However, the theoretical basis of the reverse filtration design at the present stage is insufficient, the grain size, grading, thickness and the like of the reverse filtration material are not required in particular, and the filling material with the grain size is not specified for the soil. If special measures are not adopted for control in construction, the quality of the drainage of the wall body is difficult to ensure. Furthermore, the filter material is not arranged or the particle size of the filter material is too large, so that the filter material does not play a role in reverse filtration. This results in the wall drainage failing very quickly (the drainage holes are blocked) after the wall is built.
Disclosure of Invention
Therefore, the present utility model is directed to a retaining wall drainage device, which has the advantage of being not easy to be blocked.
The utility model solves the problems by the following technical means: the utility model provides a barricade wall drainage device, includes drainage tube and filter material package, the filter material package passes through the fastener to be fixed in the one end of drainage tube, and the filter material package includes the cladding net and through the outer gel particle layer, big particle diameter filter material layer and the little particle diameter filter material layer that set gradually of cladding net cladding to interior, all separate through geotechnique's fabric between gel particle layer and the big particle diameter filter material layer, between big particle diameter filter material layer and the little particle diameter filter material layer.
Further, one end of the drainage tube, on which the filter material bag is mounted, is provided with a porous end sealing plate.
Further, the porous end sealing plate is covered with geotextile.
Further, the other end of the drainage tube is provided with a bevel connection.
Further, one end of the drainage tube, which is close to the bevel connection, is sleeved and assembled with an annular air bag belt.
Further, the fastener is a pipe clamp type fastener.
The utility model has the beneficial effects that: the retaining wall body drainage device comprises a drainage tube and a filter material bag, wherein the filter material bag is fixed at one end of the drainage tube through a fastener, the filter material bag comprises a cladding net, and a gel particle layer, a large-particle-size filter material layer and a small-particle-size filter material layer which are sequentially arranged from outside to inside and are clad through the cladding net, and the gel particle layer and the large-particle-size filter material layer and the small-particle-size filter material layer are separated through geotextiles. The filter material bag of the retaining wall body drainage device comprises the large-grain-size filter material layer and the small-grain-size filter material layer, so that the filtering effect is ensured, the drainage tube is not easy to block, and the reliability and the durability of drainage are ensured.

Detailed Description
The present utility model will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 6: the embodiment provides a retaining wall body drainage device, which comprises a drainage tube 1 and a filter material bag 3, wherein the filter material bag is fixed at one end of the drainage tube through a fastener 4, and filters water in soil body behind a wall body and then leads the water into the drainage tube; the drainage tube is the structure that water after filtering the filter material package leads to wall lateral surface and discharge, and the one end that the drainage tube installed the filter material package is provided with porous end sealing plate 1-1, and the other end is provided with the bevel connection, and porous end sealing plate covers has geotechnique's fabric, and porous end sealing plate is used for preventing the filter material entering drainage tube to lead to the filter material dispersion, can not play the filtration effect. One end of the drainage tube, which is close to the bevel connection, is sleeved and assembled with an annular air bag belt 2; after the drainage tube is inserted into a mounting hole (drainage drilling hole) on the baffle wall, when the drainage drilling hole is closed, the annular air bag belt can prevent mortar from entering, and simultaneously, the annular air bag belt plays a role of a template for unset mortar. The annular air bag belt can be provided with a plurality of groups according to the requirement.
The filter material package comprises a coating net 3-1, and a gel particle layer 3-2, a large-particle-size filter material layer 3-4 and a small-particle-size filter material layer 3-5 which are sequentially arranged from outside to inside and are coated by the coating net, wherein the gel particle layer and the large-particle-size filter material layer and the small-particle-size filter material layer are separated by a geotextile 3-4. The cladding net is used for preventing soil particles from entering, does not prevent water from entering, and wraps the filter material; the gel particle layer expands in volume when meeting water, and swells the filter material to ensure that the volume of the filter material is larger than the aperture of the drainage drilling hole. The large-particle-size filter material layer preliminarily filters water in soil body behind the wall body, so that mud and sand in the water are reduced. The small-particle-size filter material layer is used for further filtering the water body, so that the water entering the guide pipe does not contain a large amount of sediment, and the guide pipe is prevented from being blocked.
In application, as shown in fig. 6, holes are drilled (in-situ holes can be drilled) in the wall body 5 until the wall body is drilled, then the drainage tube is penetrated into the drilled holes, and the drainage tube is lightly knocked until the filter material bag penetrates through the wall body. And one side of the outer side surface of the wall body is plugged with cement mortar for drilling.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present utility model, which is intended to be covered by the scope of the claims of the present utility model.
