Pipeline orifice device for municipal engineering drainage pipeline

Abstract

The invention discloses a municipal engineering drainage pipe crossing device, which is mainly composed of a drainage board, and the drainage board is uniformly provided with drain holes penetrating up and down, and the sewage is discharged down by using the drain holes; the drainage board There are slots on both sides of the lower surface, and the slots are horizontally oriented forward and backward, and the two ports of the slots communicate with the outside of the drainage plate; in the present invention, when the surface of the filter screen has accumulated too much residue and affects the drainage, the fixing ring Take it off, and at the same time lift up to adjust the pull rope, then one side of the filter can be lifted to form a structure with one end high and one end low, and the residue accumulated on the surface of the filter can be partly shaken by the operator under the action of gravity. The residue shakes off into the slag collecting net bag, which can reduce the amount of residue attached to the surface of the filter screen, thereby improving the overall drainage speed, and this method helps to increase the service life of the filter screen.

Description

technical field [0001] The invention relates to the field of municipal engineering, in particular to a drainage pipe crossing device for municipal engineering. Background technique [0002] Municipal drainage pipes use stainless steel mesh for preliminary filtration when the actual sewage enters, which can prevent the accumulation of residues from clogging the pipes. Traditional crossing filter devices have a short service life and cannot meet actual needs, resulting in high overall replacement costs. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned situation, the present invention aims to provide a technical solution capable of solving the above-mentioned problems. [0004] A municipal engineering drainage pipeline crossing device, mainly composed of drainage boards, the drainage boards are mainly placed at the crossings, and the safety protection is realized by using the drainage boards; the drainage boards are evenly opene...
