Description

Technical Field

[0001] The utility model belongs to the technical field of sewage collection, and specifically refers to a ditch-in-ditch structure for sewage collection of riverside buildings in urban areas. Background Art

[0002] Sewage collection ditches are public facilities used to discharge domestic sewage or industrial wastewater. Sewage is discharged directly through drainage pipes without filtering structures, and sewage is directly discharged into rivers, causing black and smelly water.

[0003] At present, sewage in rivers is generally intercepted by pipelines. Pipelines are used to collect residential sewage, and new sewage trunk pipes and sewage inspection wells need to be built in the river. However, multiple sewage inspection wells in the river may cause water blockage, causing sewage from pipeline leakage to enter the river, and there is a problem of clean water in the river entering the sewage pipe, which causes great pollution to the environment. Utility Model Content

A water inlet is provided on the side of the transition chamber away from the partition net, and a water outlet is provided on the side of the separation chamber away from the partition net. The water inlet is arranged higher than the water outlet.

[0007] A filtering middle layer is installed on the outer top of the upper layer of the trench, and the filtering middle layer includes a supporting base, a retaining grille and a positioning rod. The supporting base is a frame structure and a filter net is provided at the bottom. A positioning groove is opened on the inner side wall of the supporting base. The retaining grille is installed in the positioning grooves on both sides. A downwardly recessed semi-arc positioning hole is opened at the center of the retaining grille, and the positioning rod is installed between the positioning holes to form a fixing effect.

[0008] Furthermore, a lower filtering membrane is provided at the connection between the lower layer of the trench and the upper layer of the trench.

[0009] Preferably, the positioning groove is arranged in a concave shape, and the blocking grille is inserted into the positioning groove.

[0010] As a preferred solution, the mesh diameter of the filter screen is larger than the membrane pore diameter of the lower filter membrane, forming a progressive filtration effect.

[0011] Furthermore, the retaining grille and the positioning rod are both made of corrosion-resistant materials.

[0012] Furthermore, the diameter of the positioning hole is slightly larger than the diameter of the positioning rod, and the cross-section of the positioning hole is arranged in an arc shape, so that when the positioning rod is located in the positioning hole, the center of the positioning rod is lower than the top surface of the positioning hole, thereby increasing the stability of the connection.

[0013] The beneficial effects achieved by the utility model using the above structure are as follows:

[0014] 1. The multi-layer progressive upper and lower structures are used to filter impurities, which is used to solve the problem of water blockage caused by pipe sewage interception in the existing technology and avoid environmental pollution.
