The utility model is used for preventing and treating waterlogging and laying pipelines, has low construction cost and convenient maintenance, and improves the waterlogging prevention safety of cities.
Description
Technical Field
The utility model belongs to the field of urban planning construction, relates to rainwater drainage and underground pipeline construction, and particularly relates to an urban rainwater pipe gallery.
Background
The urban rainwater pipeline is arranged by analyzing the urban rainfall, counting the average daily rainfall for many years and draining the urban rainfall in a drainage blind ditch mode according to the urban drainage standard; the urban underground pipeline layout is combined, and the urban rainwater drainage space and the pipeline laying space are compositely utilized to form a rainwater pipe gallery. Thereby improving the rainwater storage capacity, enhancing the urban toughness and realizing the intensive, economical and utilization of urban land.
Traditional urban rainwater pipeline for saving urban construction cost, generally according to many years of urban rainfall data, according to urban rainstorm or heavy rainstorm rainfall, confirm rainwater drainage pipe diameter or rainwater escape canal section, when the urban rainfall meets with super heavy rainstorm, the city will be flooded a large scale, appear "the city sees the sea" phenomenon. Traditional city utility tunnel, construction cost and management maintenance cost are higher, and are difficult to confirm the construction main part, lead to the pipeline to go into the response degree of corridor not high, and the piping lane construction degree of difficulty is great.
Disclosure of Invention
In order to overcome the problems in the prior art, the utility model aims to provide the urban rainwater pipe gallery, the pipeline is laid in the rainwater pipe gallery, the construction cost is low, the overhaul is convenient, and the urban waterlogging prevention safety is improved.
The purpose of the utility model is realized by the following technical scheme:
the utility model provides an urban rainwater piping lane which characterized in that: the rainwater pipe gallery comprises a pipe gallery space arranged underground, and the pipe gallery space is communicated with an access opening arranged on a road surface through an escalator; a pipeline support is arranged on the inner wall of the pipe gallery space, and a pipeline is laid on the pipeline support; a pedestrian path is arranged in the space of the pipe gallery; the pipe gallery space is connected with the road surface rainwater collecting port through a rainwater connecting pipe.
Further, all be equipped with the pipeline support on pipe gallery space both sides inner wall.
The port of the rainwater connecting pipe is provided with a baffle plate for preventing rainwater from spraying. The distance between the baffle and the space wall of the pipe gallery is 100 mm; the width of the baffle is 1.0 meter.
The method determines the section of the rainwater pipe gallery according to the urban drainage standard, the conventional flow rate of the ditch and the space required by pipeline laying.
The longitudinal slope of the rainwater pipe gallery is consistent with the longitudinal slope of the road in principle; the pipelines are arranged on two sides in the ditch. The pipe gallery end is connected with a downstream rainwater pipe gallery or an urban river.
The interior bottom elevation of rainwater piping lane is higher than the bottom elevation that inserts the river course to guarantee the unblocked of drainage. The rainwater pipe gallery is buried in urban public spaces such as roads and greenbelts, and certain covering soil is reserved at the upper part of the rainwater pipe gallery so as to facilitate the crossing of underground pipelines.
Set up the pedestrian space who is used for the drainage ditch desilting and the pipeline to overhaul in the rainwater piping lane. The pedestrian space has the function of draining water.
Rainwater piping lane sets up necessary access hole (has the dog-house function concurrently) according to the national standard, and the access hole top surface is level mutually with ground. The rainwater pipe gallery has the function of treating initial rainwater.
The utility model has the following beneficial effects:
compared with a directly-buried pipeline, the pipeline is laid in the rainwater pipe gallery, has the advantages of low construction cost and convenience in maintenance, and can avoid the generation of a 'road zipper';
the cross-sectional area of the pipe gallery is based on the urban drainage standard, and is checked according to the historical maximum rainfall. When the rainfall of the city is greater than the urban drainage standard, the residual space between the pipelines in the rainwater pipe gallery can be used for storing and draining water, so that the toughness of the city is enhanced, the phenomenon of 'seeing the sea in the city' is reduced, and the urban anti-waterlogging safety is improved;
through the concrete that permeates water that sets up in the rainwater piping lane, satisfy the processing requirement to the initial stage rainwater, realize the construction theory of "sponge city". The pervious concrete can be repeatedly used, and compared with the pervious concrete poured and paved on a sidewalk, the urban operation cost is greatly reduced.
The method is suitable for planning and construction of urban rainwater waterlogging prevention and control, and can be widely applied to urban land and soil space planning and urban rainwater drainage design and construction.

Detailed Description
An urban rainwater pipe gallery is shown in figure 1 and comprises a pipe gallery space 1 arranged underground, wherein the pipe gallery space is communicated with an access 5 arranged on a road surface through an escalator 9; the inner walls of the two sides of the pipe gallery space are respectively provided with a pipeline bracket 3, and pipelines 2 are laid on the pipeline brackets; a pedestrian path 4 is arranged in the space of the pipe gallery; the pipe gallery space is connected with the road surface rainwater collecting port through a rainwater connecting pipe 6. The width of the pipe gallery is not less than the sum of the widths of the pedestrian walkways and the pipeline support. The width of the access hole is not less than 700 mm.
A baffle 7 for preventing rainwater from spraying is arranged at the port of the rainwater connecting pipe. The distance between the baffle and the space wall of the pipe gallery is 100 mm; the width of the baffle is 1.0 meter.
The distance from the inner top of the rainwater pipe gallery to the ground 10 at the lowest point of the road is not less than 1.0 meter. Based on city river course depth of water generally more than 3.0 meters, rainwater pipe gallery highly according to not less than 2.0 meters control to satisfy the demand of pedestrian in the pipe gallery.
