Description

Underground drainage pipeline for municipal engineering

Technical Field

The utility model relates to the field of drainage pipelines, in particular to an underground drainage pipeline for municipal engineering.

Background

The water pipe is a water supply pipeline, modern decoration water pipes are constructed in a wall-buried mode, the water pipes are classified into three types, and the first type of the water pipes is metal pipes such as hot-dip cast iron pipes with inner plastic lining, copper pipes, stainless steel pipes and the like. The second type is plastic-clad metal pipes, such as steel-plastic clad pipes, aluminum-plastic clad pipes, etc. The third type is plastic tubing, such as PB tubing, PP-R tubing, etc.

Chinese patent No. CN 209538335U discloses an underground drainage pipe, but the working box has the following problems: the structure is too complicated, difficult installation, it is inconvenient to use, the practicality is relatively poor, and application scope is limited.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects and provides an underground drainage pipeline for municipal engineering.

The purpose of the utility model is realized by the following modes: underground drainage pipe that municipal works were used, including three-layer body and concatenation piece, the concatenation piece all can be installed in the both ends of three-layer body, so the both ends of concatenation piece all can cooperate with the both ends of three-layer body, the three-layer body is respectively by outside stereoplasm layer, middle part stereoplasm layer and inside stereoplasm layer constitute, the middle part stereoplasm layer is installed between outside stereoplasm layer and inside stereoplasm layer, the surface of middle part stereoplasm layer is connected with the inner wall of outside stereoplasm layer, the inner wall of middle part stereoplasm layer is connected with the surface of inside stereoplasm layer.

Furthermore, both ends of the middle hard layer are provided with splicing grooves matched with the splicing blocks.

Furthermore, both ends of the splicing block are provided with buckling parts used for being connected with the splicing grooves.

Furthermore, a first channel for drainage circulation is arranged in the middle of the internal hard layer, and a second channel communicated with the first channel is arranged on the splicing block.

Furthermore, outside hard coat, middle part hard coat and inside hard coat all are cylindrically, through the reducible occupation to the space of columniform setting.

Furthermore, the two ends of the external hard layer and the internal hard layer are both provided with sealing rings, and water leakage at the joint of the first channel and the second channel can be prevented through the sealing rings.

The beneficial effects produced by the utility model are as follows: but through the three-layer body and the splice that set up positive and negative direction concatenation wantonly, avoided the wrong condition of direction installation, easy installation, convenient to use, the practicality is stronger, and application scope is great.

FIG. 2 is a schematic perspective view of a block of the present invention for use in an underground drainage pipeline for municipal works;

in the figure, a sealing ring, 2-splicing blocks, 3-an outer hard layer, 4-a middle hard layer, 5-an inner hard layer, 6-a splicing groove, 7-a buckling part, 8-a first channel and 9-a second channel.

Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention is described in detail below with reference to the attached drawings.

Please refer to fig. 1-2, the underground drainage pipe for municipal works includes a three-layer pipe and a splice 2, the splice 2 can be installed at both ends of the three-layer pipe, so both ends of the splice 2 can be matched with both ends of the three-layer pipe, the three-layer pipe is composed of an external hard layer 3, a middle hard layer 4 and an internal hard layer 5, the middle hard layer 4 is installed between the external hard layer 3 and the internal hard layer 5, the outer surface of the middle hard layer 4 is connected with the inner wall of the external hard layer 3, and the inner wall of the middle hard layer 4 is connected with the outer surface of the internal hard layer 5.

And splicing grooves 6 matched with the splicing blocks 2 are formed at the two ends of the middle hard layer 4. The both ends of splice 2 all are equipped with the buckling parts 7 that are used for being connected with splice groove 6.

The middle part of the internal hard layer 5 is provided with a first channel 8 for drainage circulation, and the splicing blocks 2 are provided with a second channel 9 communicated with the first channel 8. Outside stereoplasm layer 3, middle part stereoplasm layer 4 and inside stereoplasm layer 5 all are cylindrically, through the reducible occupation to the space of columniform setting. Both ends of the external hard layer 3 and the internal hard layer 5 are provided with sealing rings 1, and the joint of the first channel 8 and the second channel 9 can be prevented from water leakage through the sealing rings 1.

The utility model discloses the operating principle of underground drainage pipe that municipal works were used is promptly through the groove of relying on that the three-layer body set up, can splice with the buckling parts 7 at splice block 2 both ends, and the buckling parts 7 at splice block 2 both ends can splice the one end of three-layer body wantonly, can prevent through sealing washer 1 that the concatenation department of three-layer body and splice block 2 from leaking.

The foregoing is a more detailed description of the utility model, taken in conjunction with specific further embodiments thereof, and it is not intended that the utility model be limited to the specific details set forth herein. It will be apparent to those skilled in the art that various modifications, additions and substitutions can be made without departing from the spirit of the utility model.
