Abstract
The utility model provides an installation structure for sewage interception of a drainage port in a hidden culvert, wherein the side wall of the hidden culvert is outwards communicated with a branch culvert, a sewage interception pipe is arranged at the bottom of the position outside the branch culvert, and one end of the sewage interception pipe, which is far away from the branch culvert, penetrates through a soil layer on the wall of the hidden culvert and is connected with an inspection well; the utility model discloses to exposing the dirty pipe damage problem of cutting outside the dark culvert, will cut dirty pipe and install in branch culvert bottom and the soil layer of dark culvert lateral wall, form effective protection to cutting dirty pipe, prevent to cut dirty pipe and be washed off by the water-washed, branch culvert sewage carries on in the dark culvert.
Description
Technical Field
The utility model relates to a municipal works secretly contain technical field, concretely relates to arrange mouthful dirty mounting structure of cutting in secretly containing.
Background
Along with the development of urbanization, the rain and sewage diversion project is widely developed nationwide. Especially, in the process of laying the sewage intercepting pipe in the hidden culvert, the sewage intercepting pipe intercepts sewage on two sides along the box culvert so as to ensure that no sewage flows into the culvert, so that the box culvert is kept in a dry state in dry seasons, and the rainwater and sewage diversion effect is achieved. The traditional method lays the sewage interception pipe connected with the branch culvert sewage drainage port outside the hidden culvert for construction convenience, so that the sewage interception pipe is exposed on a flood drainage channel of the hidden culvert and cannot form a protection effect on the flood drainage channel, the sewage interception pipe laid outside the hidden culvert is broken by water when a rainy season comes or an upstream flood is discharged, and in the branch culvert sewage is subjected to main culvert, workers need to be frequently dispatched to maintain the sewage interception pipe, so that the later operation and maintenance cost and the risk of maintenance workers are increased to a certain extent.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a mouth of a river cuts dirty mounting structure in dark culvert, to exposing the branch culvert outside dark culvert and cut dirty pipe damage problem, will cut dirty pipe and install in the soil layer of branch culvert bottom and dark culvert lateral wall, form effective protection to cutting dirty pipe, prevent to cut dirty pipe and by the water-washed absolutely, branch culvert sewage carries on in the dark culvert.
Therefore, the utility model adopts the following technical scheme:
the utility model provides a row's mouth cuts mounting structure of dirt in dark culvert which characterized in that: the hidden culvert is communicated with the branch culverts, the outlets of the branch culverts are arranged on the side wall of the hidden culvert, the bottom of the positions outside the branch culverts is provided with a sewage intercepting pipe, the sewage intercepting pipe penetrates through the hidden culvert wall to be connected with the inspection well, and the joints of the sewage intercepting pipe and the bottom of the branch culverts and the penetrating positions of the hidden culvert wall are filled with concrete and are coated with waterproof mortar for fixation.
Further: and a closure weir is arranged at the water outlet of the branch culvert.
Further: the hidden culvert side wall is arranged vertically, and the inspection well is arranged close to the wall body along the hidden culvert in the hidden culvert.
Further: the hidden culvert side wall is in a trapezoidal arrangement, and the sewage intercepting pipe is sealed and protected by adopting concrete between the hidden culvert inner side wall and the inspection well.
Further: the hidden culvert is internally provided with a sewage intercepting main pipe, an inspection well is arranged at the position corresponding to the outlet of the branch culvert, and the sewage intercepting main pipe is connected with the inspection well.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses to the branch culvert sewage intercepting pipe damage problem that exposes outside, install the sewage intercepting pipe on branch culvert bottom and dark culvert wall, form effective protection to the sewage intercepting pipe, when preventing rainy season or upper reaches flood discharge, the sewage intercepting pipe is broken by the water flush, branch culvert sewage carries out in the dark culvert, leads to producing the black and odorous water body in the dark culvert, and the utility model discloses reduce later stage fortune dimension cost and the risk of culvert maintainer to a certain extent; further, the utility model discloses set up the weir that dams at the mouth of a river delivery port, prevent the sewage overflow.
Drawings
FIG. 1 is a drainage cut-off installation structure with a vertical hidden culvert side wall;
fig. 2 is a drainage cut-off installation structure with a trapezoidal hidden culvert side wall.
Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
As shown in figure 1 and figure 2, the utility model provides a pair of arrange mouthful dirty mounting structure of cutting in dark culvert, dark culvert 7 is linked together with branch culvert 3, and branch culvert 3's export is on the lateral wall of dark culvert 7, and the bottom of branch culvert 3 outside position 8 is equipped with cuts dirty pipe 2, cuts dirty pipe 2 and passes dark culvert 7 culvert wall and be connected with inspection shaft 6.
The water outlet of the branch culvert 3 is provided with a cut-off weir 1, the cut-off weir 1 is arranged by adopting brick building, cement mortar is coated, and the cut-off weir 1 is arranged to ensure that sewage overflowing of the sewage intercepting pipe 2 enters the hidden culvert 7 in rainy season.
And concrete is filled between the joint of the sewage interception pipe 2 and the bottom of the branch culvert 3 and the penetrating part of the culvert wall of the dark culvert 7, and waterproof mortar is smeared for fixation.
The side wall of the hidden culvert 7 is arranged vertically, and the inspection well 6 is arranged close to the wall body along the hidden culvert 7 in the hidden culvert 7.
The side wall of the hidden culvert 7 is in a trapezoidal arrangement, and the sewage interception pipe 2 is sealed and protected by adopting concrete between the side wall of the hidden culvert 7 and the inspection well 6.
The hidden culvert 7 is internally provided with a sewage intercepting main pipe 5, an inspection well 6 is arranged at the position corresponding to the outlet of the branch culvert 3, and the sewage intercepting main pipe 5 is connected with the inspection well 6.
The installation step of the sewage interception and drainage port comprises the following steps:
s1: when the sewage intercepting pipe 2 is not laid, holes are punched on the side wall of the hidden culvert 7 and the bottom of the outer side position of the branch culvert 3.
S2: clear away the soil layer in two holes, install sewage intercepting pipe 2 in two holes, adopt concrete and cement mortar to fill fixedly around sewage intercepting pipe 2 after the installation is accomplished, prevent in the sewage infiltration earth.
S3: after finishing laying of sewage intercepting pipe 2, casting inspection shaft 6 on sewage intercepting main pipe 5, extending sewage intercepting pipe 2 installed on the side wall of hidden culvert 1 into inspection shaft 6, chiseling the side wall of hidden culvert 1 before pouring inspection shaft 6, and forming a whole by inspection shaft 5 and the side wall of hidden culvert 7.
