Specifically, the first pipeline 100 may be disposed along a road extending direction, for example, the first pipeline 100 is buried under a middle isolation belt of a first highway, or the first pipeline 100 is buried under a highway sidewalk. The silt mixed in the runoff subsides gradually along with the rivers under the action of gravity, for avoiding silt deposit in the bottom of first passageway 101, along the extending direction of first pipeline 100, is equipped with first soil reservoir 200 at every certain distance. The distance between two adjacent first soil reservoirs 200 is 3500m to 4500m, so that the runoff can be discharged into the first soil reservoirs 200 before the solid soil is deposited to the bottom of the first channel 101. For example, 3800m, 4000m, or 4200 m may be selected as the distance between two adjacent first soil reservoirs 200, and the distance between two adjacent first soil reservoirs 200 is usually 4000m in consideration of the surface silt particle size and the settling velocity, so as to prevent the first passage 101 from being clogged. Mixed silt deposit in the rainwater is in first soil storage pond 200, and the accessible machinery is drawn mud the mode and is dredged, compares in dredging first pipeline 100 and has reduced the operation degree of difficulty by a wide margin. The rainwater in the first pipe 100 and the first soil reservoir 200 may converge to the open channel to be concentrated into the sea.

As shown in fig. 1, the underground piping further comprises a second dirt storage tank 400, and a second opening is formed at the bottom of the second piping 300 and is in fluid communication with the second dirt storage tank 400. Wherein the solid dirt in the second passage 301 can be deposited into the second dirt storage tank 400, thereby preventing the second pipe 300 from being fouled. The solid sewage in the first pipeline 100 is mostly silt, the solid sewage in the second pipeline 300 is mostly organic sewage which can generate biogas, the silt is deposited in the first sewage storage tank 200, and the organic sewage is deposited in the second sewage storage tank 400, so that the solid sewage can be classified and treated, and the biogas can be prepared by using the organic sewage.

As shown in fig. 1, the first duct 100 includes: the first splicing body 110 and the second splicing body 120, the first splicing body 110 and the second splicing body 120 are detachably connected. The first splicing body 110 is provided with a first splicing groove, the second splicing body 120 is provided with a second splicing groove, and the first splicing body 110 and the second splicing body 120 can be detachably connected in a clamping or soil covering and embedding manner; after the first splicing body 110 is connected with the second splicing body 120, the first splicing groove and the second splicing groove form a first channel 101 with a rectangular cross section. The first splicing body 110 and the second splicing body 120 can be formed by pouring concrete, and reinforcing steel bars for reinforcing the structural strength are respectively arranged in the first splicing body 110 and the second splicing body 120. The first splicing body 110 and the second splicing body 120 are respectively poured, so that the first pipeline 100 can be conveniently machined and formed, and when the first pipeline 100 is laid, the first splicing body 110 and the second splicing body 120 can be respectively hoisted, so that the hoisting weight is reduced.

The two first pipelines 100 are connected end to end in sequence, the sleeve body of one first pipeline 100 is inserted into the groove of the other first pipeline 100, and the two first pipelines 100 are extruded to move oppositely, so that the contact area of the joint of the first interface part 102 and the second interface part 103 can be increased, and the sealing performance of the joint of the two first pipelines 100 is further enhanced. The first pipe 100 is manufactured in a segmented manner, thereby facilitating the processing and transportation of the first pipe 100.

Further, the length of the first pipe 100 ranges from 4m to 6 m. For example, the first pipe 100 may be formed of concrete cast and have a length of 4.5m, 5m, or 5.5 m. Therefore, the inconvenience of lifting caused by the overlarge length of the first pipeline 100 is avoided, and the first pipeline 100 can be prevented from being broken due to the bending stress in the lifting process by properly shortening the length of the first pipeline 100. In addition, in order to reduce the number of the first pipes 100 within a certain construction distance, the length of the first pipe 100 should be 4m or more.

Further, the width dimension of the cross section of the first channel 101 ranges from 1.6m to 2.0m, and the height dimension of the cross section of the first channel 101 ranges from 1.6m to 2.0 m. Specifically, the cross-sectional dimension of the first channel 101 may be 1.8m × 1.8m, so that the requirement of the caliber of radial flow discharge can be met, and excessive manufacturing cost due to the overlarge cross-sectional dimension of the first channel 101 can be avoided.

Further, the thickness of the sidewall of the first duct 100 is 0.12m to 0.17 m. For example, the first pipe 100 may have a sidewall thickness of 0.15m, which is formed by casting concrete, and a reinforcing bar is provided therein as a support, thereby securing a stable structure of the first pipe 100.

Further, the wall thickness of the top of the first pipe 100 is 0.25m to 0.35 m. Specifically, the wall thickness of the top of the first pipe 100 may be set to 0.3m, and the wall thickness of the top of the first pipe 100 is thickened so as to withstand the pressure of pedestrians and vehicles on the surface of the earth, thereby preventing the top of the first pipe 100 from collapsing.

Further, the width dimension of the cross section of the second channel 301 ranges from 0.5m to 0.7m, and the height dimension of the cross section of the second channel 301 ranges from 0.7m to 0.9 m. In order to avoid the second channel 301 occupying too much cross-sectional dimension of the first channel 101, so as to ensure that the first channel 101 can play a role in draining the stagnant water in time under the condition of heavy rainfall, the cross-sectional dimension of the second channel 301 should be reduced appropriately. As the domestic sewage flow is small, the sectional dimension of the second passage 301 is set to be 0.6m multiplied by 0.8m, so that the domestic sewage discharge requirement can be met.

When the underground corridor pipeline is constructed, excavating a tunnel by using an excavating head with the length of 2.2m multiplied by 3.5m, wherein the tunnel position is selected at an isolation belt of a first-level road or a sidewalk of the road; after the excavation of the tunnel is completed, sand with the thickness of 0.4m is paved at the bottom of the tunnel, the bottom end face of the first pipeline 100 is borne by the sand, the first pipeline 100 is prevented from being broken due to uneven stress on the bottom end face, and finally the first pipeline 100 is buried in the filling soil in the tunnel. Taking the example that the first pipeline 100 is buried under the road isolation belt, the thickness of the soil covering the top of the first pipeline 100 is more than or equal to 1m, so that flowers and plants can be planted in the soil above the first pipeline 100.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
