Embodiment Construction

[0043] The following is attached Figure 1-5 The application is described in further detail.

[0044] The embodiment of the present application discloses a construction method of a permeable structure system. refer to figure 1 , including the following steps,

[0045] Step S1: Excavating a foundation pit.

[0046] S11: Determine the center line of the trench excavation according to the excavation plan of the foundation pit.

[0047] S12: Use a shovel to excavate trenches, and effectively protect various types of underground pipelines during operation.

[0048] S13: Based on the trench, determine the location of the foundation pit, and dig the trench earthwork.

[0049] S14: Trench excavation is mainly by mechanical excavation, supplemented by manual work. Excavate mechanically to a place 0.2m above the design elevation, and use manual excavation and trench cleaning.

[0050] Step S2: laying the sand cushion.

[0051] S21: After the excavation of the foundation pit is c...

Abstract

The invention relates to a permeable structure system construction method which comprises the following steps: a foundation pit is excavated; the foundation pit base is leveled and tamped, and then a sand cushion layer is laid; water-permeable geotextile is laid on the upper surface of the sand cushion layer, and then waterproof geomembranes are laid on the two sides of the foundation pit; a steel belt corrugated pipe is placed, and then an inspection well is bricked at the pipe opening position of the steel belt corrugated pipe; a permeation pipe is installed, a sand sediment trap is bricked at the position of a pipe opening of the permeation pipe, dredging equipment is installed in the permeation pipe, and a drainage pipe communicated with a road catch basin and an overflow pipe communicated with an inspection well are installed on the side wall of the sand sediment trap and communicated with an inner cavity of the sand sediment trap; the foundation pit is backfilled with graded broken stone to the elevation and then compacted; and the permeable concrete is paved on the upper surface of the graded broken stone to the elevation position. The method has the effect of improving the utilization rate of rainwater resources.

Description

technical field [0001] The application relates to the field of municipal engineering, in particular to a construction method for a permeable structure system. Background technique [0002] Sponge city is a historic and strategic step to realize the six-in-one comprehensive drainage and ecological drainage of "seepage, stagnation, storage, purification, use, and drainage" from the era of fast drainage, timely and nearby drainage, and rapid drainage. change. [0003] The sponge city in the related art replaces the asphalt pavement with permeable concrete to improve the safety of the asphalt pavement in rainy days and reduce the risk of water accumulation on the road. However, the rainwater passing through the permeable concrete is directly discharged through the drainage pipes buried below the road surface, and the utilization rate of rainwater resources is low. Contents of the invention [0004] In order to improve the utilization rate of rainwater resources, the applicat...
