Description

A bridge-type water filter pipe with crisscross water filter holes

technical field

The utility model relates to the technical field of bridge-type water filter pipes, in particular to a bridge-type water filter pipe with crisscross water filter holes.

Background technique

In the process of drilling the bridge-type water filter pipe in the past, it is easy to damage the shape of the pipe body and the water filter hole, and at the same time, the sediment and its particles are also easy to block the water filter hole of the bridge-type water filter pipe. How to ensure the effectiveness of the bridge-type water filter pipe And durability are technical problems that need to be solved urgently.

Utility model content

In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a bridge-type water filter pipe with crisscross water filter holes to ensure the effectiveness and durability of the bridge-type water filter pipe.

In order to achieve the above object, the technical scheme of the utility model is:

A bridge-type water filter pipe with criss-cross water filter holes, including bridge-type water filter holes 3 criss-crossed outside the bridge-type water filter pipe, the bridge-type water filter holes 3 are wrapped with a layer of glass fiber mesh 2, and the glass fiber mesh 2 is wrapped There is a layer of spiral wrapping wire 1 .

Described bridge type water filter hole 3, its aperture is 10mm.

The glass fiber mesh 2 is a network structure formed by interweaving glass fibers.

The spiral wrapping wire 1 adopts steel wire, and is evenly wound outside the glass fiber mesh 2 with a gap of 20 mm.

The beneficial effects of the utility model are: the use of spiral wrapping wire 1 and glass fiber net 2 greatly increases the pressure of the filter pipe against the hole wall and other external loads when drilling; the glass fiber net 2 has good corrosion resistance and mechanical strength High and cheap; the spiral wrapping silk 1 has protected the water filter pipe especially. The utility model is suitable for water filtration projects in various complicated geological conditions, prolongs the service life of the water filter pipe, and ensures the effectiveness and durability of the bridge type water filter pipe.

Fig. 1 is a schematic cross-sectional view of an embodiment of the utility model.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Referring to Fig. 1, a bridge-type water filter pipe with criss-crossed water filter holes, including bridge-type water filter holes 3 criss-crossed outside the bridge-type water filter pipe, the bridge-type water filter holes 3 are wrapped with a layer of glass fiber mesh 2, and the glass fiber The net 2 is wrapped with a layer of spiral wrapping wire 1, and the bridge filter holes 3 are not closely arranged, but arranged in a criss-cross pattern, which increases the efficiency of filtering water and is suitable for various complex geological conditions. The water hole 3 can also increase the strength of the water filter pipe.

The diameter of the bridge-type water filter hole 3 is 10mm, and the bridge-type water filter hole 3 can filter extremely small particles, so that the sand content of the filtered water is greatly reduced.

The glass fiber mesh 2 is a network structure formed by interlacing glass fibers, which can filter medium-sized particles and slightly larger particles, and reduce the blockage of the innermost core water filter holes.

The spiral wrapping wire 1 adopts steel wire, and is evenly wound outside the glass fiber mesh 2 with a gap of 20mm, so as to improve the rigidity and strength of the whole water filter pipe and reduce the damage of the water filter pipe during the drilling process.

The working principle of the utility model is:

When in use, first use the machine to excavate the pipeline, and then push the bridge-type water filter pipe with criss-cross water filter holes clockwise inward until reaching the destination. The outermost spiral wrapping wire 1 first filters a layer of large particles; glass The fiber net 2 filters the fine sand; after the bridge-type water filter hole 3 is filtered, water with less impurities can be obtained. Such layered water filtration can prevent the innermost bridge-type water filter hole 3 from being blocked by particles, resulting in a greatly reduced water filtration efficiency. At the same time, the strength of the filter pipe is also increased, so that the service life can be extended.
