Problems solved by technology

[0003] At present, most sponge cities use a single sponge construction, and the low-impact development (LID) facilities are divided by infrastructure or roads, so that they cannot communicate with each other, so some of the low-impact development (LID) facilities will reach water storage The rainwater at the depth of the layer is discharged through the overflow well, while other low-impact development (LID) facilities do not reach the depth of the aquifer, resulting in the overall retention and storage of the sponge not reaching the maximum efficiency

Embodiment 1

[0044] The embodiment of the present invention discloses a construction method of rainwater infiltration and storage facilities between LID facilities, including the following construction steps:

[0045] Step 1: Determine the buried height, buried position and pipe diameter of the permeable pipeline 1 through design calculations, draw construction drawings according to the calculation results, and select the material of the permeable pipeline 1 according to the construction ground surface facilities;

[0046] Step 2: Carry out positioning and setting out at the construction site according to the construction drawings, determine the basic construction location, check the underground pipeline facilities and cable facilities, and carry out earthwork excavation at the positioning and setting out position to form a base;

[0047] Step 3: Lay the base pad 5 on the base, install the permeable pipe 1 on the base pad 5 in the base, and fill the gap between the base and the permeable pi...

Embodiment 2

[0052] Increase on the basis of embodiment 1:

[0053] The base formed after the earthwork excavation in the step 2 is a trench, and the preliminary construction treatment is carried out after the trench is formed.

[0054] When the soil is normal and the groundwater level is lower than the bottom of the ditch, straight grooves can be opened, but the groove depth shall not exceed the following regulations: sandy soil and gravel soil shall not exceed 1.0m; loamy soil and loamy soil shall not exceed 1.25m.

[0055]When installing the permeable pipeline 1 in the trench, it is hoisted and placed and installed in sections. After the installation is completed, the top of the trench is backfilled with soil 2 and compacted.

Embodiment 3

[0057] Increase on the basis of embodiment 1;

[0058] The base formed after the earthwork excavation in the step 2 is a culvert, and the preliminary construction treatment is carried out after the culvert is formed.

[0059] When the permeable pipe passes through the road, a steel casing shall be installed on the outside.

[0060] When positioning and setting out the line, set the theodolite on the center line of the working well and the receiving point, determine the position along the line passing the center point, pull out the level line connecting the two points, and use the vertical line and tape measure to determine the equipment of the pipe jacking machine Location.

[0061] The permeable pipe 1 is installed in the culvert by dragging and jacking and installed in sections. After the installation is completed, the gap between the culvert and the permeable pipe 1 is filled and backfilled.

Abstract

The invention relates to the technical field of municipal drainage, in particular to a rainwater permeation regulation and storage facility between LID facilities and a construction method of the rainwater permeation regulation and storage facility. The construction method comprises the following construction steps of design, calculation and construction drawing drawing, positioning, paying off, earth excavation, base treatment, permeable pipeline installation and inspection and acceptance. The rainwater permeation regulation and storage facility comprises a permeable pipeline and filtering pebbles, the permeable pipeline is buried in the bottom of covering soil, one end of the permeable pipeline is connected with a first LID facility, the other end of the permeable pipeline is connected with a second LID facility, the two ends of the permeable pipeline are covered with permeable geotextile, and the two ends of the permeable pipeline are buried under the filtering pebbles. The two LID facilities are connected through the permeable pipeline to conduct permeation and exchange of rainwater, meanwhile, the two ends of the permeable pipeline are filtered through the geotechnical cloth and the pebbles, sediment deposition in the permeable pipeline is reduced, part of rainwater can be stored in the pipeline, the regulation and storage effect is achieved, and rainwater permeation and exchange between the LID facilities are enhanced.

Description

technical field [0001] The invention relates to the technical field of municipal drainage, in particular to a rainwater infiltration storage facility between LID facilities and a construction method thereof. Background technique [0002] Sponge cities have good "elasticity" in adapting to sudden changes in the environment and coping with natural disasters caused by large amounts of rainwater. LID (Low Impact Development: low-impact development) facilities are used to make full and reasonable use of rainwater. When it rains, water is absorbed and stored. Water, water seepage, water purification, release and use the stored water when needed, and realize the free migration of rainwater in the city. [0003] At present, most sponge cities use a single sponge construction, and the low-impact development (LID) facilities are divided by infrastructure or roads, so that they cannot communicate with each other, so some of the low-impact development (LID) facilities will reach water s...
