Description

Grid plate type water drain pipe

Technical Field

The invention relates to a drain pipe for draining water on the side wall of a foundation pit, belonging to the field of foundation pit supporting engineering.

Background

The drain pipe on the side wall of the foundation pit is an important drainage measure and has the functions of draining underground water in the side wall of the foundation pit and eliminating the influence of the underground water on the stability of the foundation pit. The water drain pipe consists of a PVC pipe wrapped with a reverse filter layer and is arranged in a pre-drilled hole. The drainage hole structure is inconvenient to operate because the water inlet side needs to be externally coated with the inverted filter layer formed by the sand gravel, and the inverted filter layer is irregular in shape and difficult to install in the round hole.

An object of the utility model is to provide a fashioned grid plate-type wash-out pipe of easy field installation to solve the problem that provides among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a grid plate type water drain pipe comprises an annular plate, a water baffle, a PVC pipe and gauze; a plurality of annular plates are integrally formed on the periphery of one end of the PVC pipe; the periphery of the PVC pipe penetrates through the annular plate and is provided with two water baffles; the annular plate is divided into an upper annular plate and a lower annular plate; the side wall of the PVC pipe is provided with a plurality of water guide holes corresponding to the upper annular plate.

The spacing between the two annular plates was 20 mm.

The included angle of the two water baffles is 160 degrees.

The outer side of the annular plate is wrapped with gauze which is fixed by a plurality of binding belts.

The novel beneficial effect of this use is:

1. the utility model discloses the water-drain pipe can be at the one shot forming in the mill, need not the inverted filter, and on-the-spot preparation simple process, simple to operate.

2. This use grid plate-type structure that novel annular plate formed to combine the gauze of outsourcing, can support soil hole pore wall well, ensure that the pore wall is stable, drainage channel can not blockked up by the soil granule. The special water baffle can make the underground water which penetrates through the gauze flow into the PVC pipe.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to fig. 1-4 of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

A grid plate type water drain pipe comprises an annular plate, a water baffle, a PVC pipe and gauze;

the periphery of one end of the PVC pipe 1 is integrally provided with a plurality of annular plates 2; the periphery of the PVC pipe 1 penetrates through the annular plate 2 and is provided with two water baffles 3; the annular plate 2 is divided into an upper annular plate and a lower annular plate; the side wall of the PVC pipe 1 is provided with a plurality of water guide holes 4 corresponding to the upper annular plate.

The spacing between the two annular plates was 20 mm.

The included angle of the two water baffles 3 is 160 degrees.

The outer side of the annular plate 2 is wrapped with gauze 5, and the gauze 5 is fixed by a plurality of binding belts.

Wherein the diameter of the PVC pipe is 50 mm; the inner diameter of the annular plate is 50mm, the outer diameter is 100mm, the thickness is 5mm, and the distance between the annular plates is 25 mm; the width of the water baffle is 20 mm; the aperture of the water guide hole is 3 mm.

The annular plates are uniformly connected to the PVC pipe according to the interval of 20mm to form a grid plate type cylinder structure.

Two sides of the PVC pipe are respectively provided with a water baffle, the water baffles are vertically intersected with the annular plate, and the two plates form an included angle of 160 degrees.

And drilling a plurality of water guide holes on the upper side of the PVC pipe, namely the part above the water baffle, as a channel for the underground water to enter the PVC pipe.

The outer side and the tail end of the cylinder structure are wrapped by gauze and fixed by a binding belt.

And a manual or mechanical drilling mode is adopted on the side wall of the foundation pit, the drilling elevation angle is 15 degrees, the diameter is 110mm, and the length is 300 mm.

When the grid plate type cylinder is used on site, the periphery and the tail end of the PVC pipe are wrapped by gauze to form a cylinder, the well-made grid plate type cylinder is inserted into a drill hole, and the water collecting surface of the water baffle is required to face upwards. Underground water in the soil layer permeates into the annular plate intervals through the gauze, is collected through the water baffle, flows into the PVC pipe through the small hole on the upper side of the PVC pipe, and is finally discharged out of the soil body on the side wall of the foundation pit. Because this outlet is the one shot forming structure, the clearance of pulling out easily, and secondary simple to operate. The grid plate type structure formed in one step is combined with the gauze wrapped outside, so that the wall of the soil hole can be well supported, the stability of the wall of the soil hole is ensured, and the drainage channel cannot be blocked by soil particles.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.

It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

It should be noted that the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and if not stated otherwise, the terms have no special meaning, and therefore, the scope of the present invention should not be construed as being limited.
