[0018] A construction method for a municipal garden drain outlet structure, the construction method is as follows:

[0019] 1. Before installation, the user needs to dig a pit foundation that is compatible with the drainage structure in the installation area. Then, after the user has laid the fine sand layer, arrange multiple drainage pipe bodies on the top of the fine sand layer. The number of drainage pipe bodies used can be increased according to the actual number required by the user.

[0020] 2. Then, the user places the connecting sleeve between two adjacent drainage pipe bodies, and then inserts the arc-shaped blocks at the opposite ends of the two drainage pipe bodies into the arc-shaped grooves at the bottom of the inner cavity of the connecting sleeve, and pushes the drainage pipe bodies with force so that the top of one side of the drainage pipe bodies squeezes the wedge-shaped limit block, and the top inclined surface of the wedge-shaped limit block moves downward under the squeeze. At this time, the spring is compressed until the drainage pipe body is completely inserted into the inner cavity of the connecting sleeve. The spring pushes the wedge-shaped limit block upward, so that the wedge-shaped limit block is inserted into the inner cavity of the rectangular limit through hole.

[0021] 3. Then, the user lays the infiltration box on the left side of the two drainage pipe bodies, and connects the feed pipe with the infiltration box through the discharge pipe. Finally, the user pours the concrete layer on both sides of the drainage pipe body and the infiltration box to fix them in place and make the top of the drainage pipe body and the infiltration box level with the ground, and then fix the anti-slip mat on the top of the drainage pipe body by tapping.

[0022] 4. During use, ground water flows from the top of the drainage pipe body into the inner cavity of the drainage pipe body, and is drained through the inner cavity of the drainage pipe body. After entering the inner cavity of the drainage pipe body, debris in the water is blocked by the filter plate and flows into the inner cavity of the infiltration box through the discharge through hole, the feed pipe and the discharge pipe. The solid-liquid mixture in the inner cavity of the infiltration box is filtered through the geotextile and gravel layer, and finally the liquid is discharged from the holes, leaving the solid waste in the inner cavity of the infiltration box. The user only needs to lift up the left side of the shielding plate and regularly clean the solid waste in the inner cavity of the infiltration box.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention connects and installs the drainage pipe body and the connecting sleeve through the setting of a limiting mechanism, and then limits and fixes the positions of the drainage pipe body and the infiltration box through the setting of a construction structure. Then, drainage is carried out through the setting of the drainage pipe body, and the solid-liquid mixture is transported to the inner cavity of the infiltration box through the setting of a separation mechanism. The liquid in the solid-liquid mixture is infiltrated and separated through the setting of the infiltration mechanism and the infiltration box, so as to achieve the purposes of fast installation speed, high drainage efficiency, prevention of blockage and easy cleaning. The municipal garden drainage outlet structure and construction method solve the problem that due to the single setting of the drainage pipe, ground impurities are easily retained after entering the drainage pipe, and the equivalent accumulation causes the blockage of the drainage pipe, which eventually leads to the inability to drain water. In addition, the existing drainage outlet structure discharges solid and liquid through the same path, and the solid causes a certain obstruction to the liquid, resulting in low drainage efficiency and water accumulation on the ground.

Then, after the user has laid the fine sand layer 72, multiple drainage pipe bodies 1 are arranged on the top of the fine sand layer 72. The number of drainage pipe bodies 1 used can be increased according to the actual number required by the user.

[0052] 2.

[0054] 4. During use, ground water flows from the top of the drainage pipe body 1 into the inner cavity of the drainage pipe body 1, and is drained through the inner cavity of the drainage pipe body 1. After entering the inner cavity of the drainage pipe body 1, debris in the water is blocked by the filter plate 41, and flows into the inner cavity of the infiltration box 5 through the discharge through hole 42, the feed pipe 43 and the discharge pipe 44. The solid-liquid mixture in the inner cavity of the infiltration box 5 is filtered through the geotextile 62 and the gravel layer 63, and finally the liquid is discharged from the hole 61, and the solid waste is retained in the inner cavity of the infiltration box 5. The user only needs to lift up the left side of the shielding plate 81 and regularly clean the solid waste in the inner cavity of the infiltration box 5.

After that, after the user has laid the fine sand layer (72), a plurality of drainage pipe bodies (1) are arranged on top of the fine sand layer (72). The number of drainage pipe bodies (1) used can be increased according to the actual number required by the user; 2. Subsequently, the user places the connecting sleeve (2) between two adjacent drainage pipe bodies (1), and then inserts the arc-shaped clamping blocks (9) at opposite ends of the two drainage pipe bodies (1) into the arc-shaped clamping grooves (10) at the bottom of the inner cavity of the connecting sleeve (2), and pushes the drainage pipe body (1) with force, so that the top of one side of the drainage pipe body (1) squeezes the wedge-shaped limit block (35), and the top inclined surface of the wedge-shaped limit block (35) moves downward under the squeezing, and at this time the spring (34) is compressed until the drainage pipe body (1) is completely inserted into the inner cavity of the connecting sleeve (2), and then the spring (34) pushes the wedge-shaped limit block (35) upward, so that the wedge-shaped limit block (35) is inserted into the inner cavity of the rectangular limit through hole (36); 3. Subsequently, the user lays the infiltration box (5) on the left side of the two drainage pipe bodies (1), and connects the feed pipe (43) to the infiltration box (5) through the discharge pipe (44). Finally, the user pours the concrete layer (73) on both sides of the drainage pipe body (1) and the infiltration box (5) to fix them in position and make the tops of the drainage pipe body (1) and the infiltration box (5) level with the ground. Then, the anti-skid pad (13) is fixed to the top of the drainage pipe body (1) by tapping.

4. During use, surface water flows from the top of the drainage pipe body (1) into the inner cavity of the drainage pipe body (1), and is drained through the inner cavity of the drainage pipe body (1). After entering the inner cavity of the drainage pipe body (1), debris in the water is blocked by the filter plate (41) and flows into the inner cavity of the infiltration box (5) through the discharge through hole (42), the feed pipe (43) and the discharge pipe (44). The solid-liquid mixture in the inner cavity of the infiltration box (5) is filtered through the geotextile (62) and the gravel layer (63), and the liquid is finally discharged through the hole (61), leaving the solid waste in the inner cavity of the infiltration box (5). The user only needs to lift up the left side of the shielding plate (81) to regularly clean the solid waste in the inner cavity of the infiltration box (5).
