[0026] With the urgency of sewage treatment, more and more sewage interception pipeline projects have been launched. At the same time, many unprecedented and difficult pipeline laying situations have also emerged. One of them is the need to intercept sewage from the earthen slopes on both sides of the river.

[0027] The following describes in detail the overall structure, working principle and technical effects of the narrow river slope sewage interception pipeline structure 110 provided by the present invention through examples and in combination with the accompanying drawings, as well as the detailed steps, implementation principles and technical effects of the corresponding narrow river slope sewage interception pipeline laying method.

[0028] Example 1: The narrow river slope sewage interception pipeline structure provided by the present invention is mainly used for pipeline construction work where there are many obstacles on both sides of the river 100, making it difficult for existing construction machinery and equipment to enter for construction.

[0029] See also Figure 1 and Figure 3 The present invention provides a narrow river slope sewage interception pipeline structure, which can be set on the slope 110 on both sides of the river 100 and used for sewage interception work of houses 500 on both sides of the slope 110.

[0030] Specifically, the houses 500 on both sides of the earth slope 110 are connected to the sewage pipe 600. The end of the sewage pipe 600 away from the house 500 is set toward the river 100. The sewage in the sewage pipe 600 is collected through the sewage interception pipe 200.

[0031] The present invention provides a narrow river earth slope sewage interception pipe structure, comprising a sewage interception pipe 200 arranged on earth slopes 110 on both sides of the river 100, and a fixing assembly 300 for fixing the sewage interception pipe 200 and the earth slope 110.

[0032] The sewage interception pipe 200 is arranged along the river 100 and is used to collect sewage discharged from multiple sewage pipes 600.

[0033] Specifically, the output end of the sewage pipe 600 can be set above the sewage interception pipe 200, and accordingly, an opening for sewage to enter is opened above the sewage interception pipe 200; or an opening is opened at a corresponding position of the sewage interception pipe 200, and the sewage pipe 600 is directly connected to the sewage interception pipe 200 through the opening.

[0034] In this embodiment, the fixing assembly 300 includes a concrete pier 310 for fixing the sewage interception pipe 200. The upper end of the concrete pier 310 is formed with a platform surface for supporting the sewage interception pipe 200, and the lower end of the concrete pier 310 is fixedly connected to the earth slope 110 through a concrete pier fixing member 320.

[0035] See also Figure 1 and Figure 2 In this embodiment, the concrete pier fixing member 320 includes two first fixing members 321 arranged perpendicular to the ground and two second fixing members 322 arranged perpendicular to the earth slope 110 .

[0036] In actual work, the ends of the first fixing member 321 and the second fixing member 322 away from the concrete pier 310 are driven into the earth slope 110 and are respectively connected to the earth slope 110; the other ends are respectively connected to the concrete pier 310. The two first fixing members 321 and the two second fixing members 322 form an oblique steel bar system in the concrete pier 310 to fix the concrete pier 310.

[0037] The arrangement of the first fixing member 321 and the second fixing member 322 can, on the one hand, support the concrete pier 310 and the sewage interception pipe 200 ; on the other hand, can also reinforce the earth slopes 110 on both sides of the river 100 .

[0038] In this embodiment, the first fixing member 321 and the second fixing member 322 are both multiple sections of connected anti-corrosion steel bars.

[0039] Specifically, each section of steel bar is connected by a steel bar connector 323; the length of each section of steel bar is , exemplary, It can be 0.5m, 1m, or 1.5m; the total length of the connected steel bars is L, and L≥3m. For example, L can be 3m, 4m, or 5m.

[0040] In this embodiment, the diameter of the steel bar is φ, φ≥28 mm; illustratively, φ can be 28 mm, 29 mm, or 30 mm.

[0041] Furthermore, both ends of the steel bars need to be pre-threaded using a CNC steel bar thread rolling machine, and the steel bars are fixed in the soil slope 110 by manual driving. For the geology of the relatively loose soil slope 110, a manual hydraulic driving method can be used; in other embodiments, manual hydraulic and other steel bar driving methods can also be used, and the operator can choose the steel bar driving method according to actual work needs.

[0042] Please continue reading Figure 2 In order to further fix the sewage interception pipe 200 and prevent the sewage interception pipe 200 from shifting and falling off, in this embodiment, a pipe fixing member 400 for fixing the sewage interception pipe 200 is provided on the concrete pier 310.

[0043] Furthermore, the pipe fixing member 400 includes a third fixing member 410 and a plurality of fourth fixing members 420 , wherein the third fixing member 410 is arranged around the outer wall of the sewage interception pipe 200 and is fixedly connected to the concrete pier 310 through the plurality of fourth fixing members 420 .

[0044] Specifically, the third fixing member 410 is a rubber belt or a steel plate with an arc-shaped structure, and the fourth fixing member 420 is an anchor bolt.

[0045] During the fixing process, the arc structure fits in contact with the outer wall of the sewage interception pipe 200 , and both ends of the arc structure are fixed to the concrete pier 310 via the fourth fixing member 420 .

[0046] In this embodiment, the sewage interception pipe 200 can be a HDPE pipe, a PVC pipe, a steel pipe or a ductile iron pipe.

[0047] It should be noted that when the sewage interception pipe 200 is an HDPE pipe or a PVC pipe, adjacent sewage interception pipes 200 can be hot-melt connected using portable hot-melt equipment; when the sewage interception pipe 200 is a steel pipe, adjacent sewage interception pipes 200 can be connected by welding; when the sewage interception pipe 200 is a ductile iron pipe, adjacent sewage interception pipes 200 can be connected by load-bearing connection.

[0048] For example, in this embodiment, the construction site on both sides of the river 100 is limited. In order to facilitate manual construction, the sewage interception pipe 200 is a PVC pipe.

[0049] The narrow river slope sewage interception pipeline structure provided in this embodiment can at least achieve the following technical effects: The concrete pier fixings 320 and the concrete pier 310 are both manually driven in and manually poured, so that when construction machinery and equipment are difficult to enter, fixed points for fixing the sewage interception pipe 200 can be set on the earth slope 110 on both sides of the river 100 to support the continuously installed sewage interception pipe 200; at the same time, the lightweight concrete pier 310 will not generate too much additional load on the slope surface of the earth slope 110, thereby avoiding the collapse of the earth slope 110 due to excessive bearing load.

[0050] Example 2: See also Figure 4 Based on the first embodiment, this embodiment provides a method for laying sewage interception pipes on a narrow river slope, including the following steps: S100, determining the arrangement points of multiple fixing components 300 as pipeline support points; In this embodiment, the sewage interception pipe 200 is arranged along the direction of the river 100. Accordingly, the pipe support points should be arranged along the direction of the river 100 or the direction of the earth slopes 110 on both sides of the river 100 to achieve the fixation of the sewage interception pipe 200.

[0051] Specifically, the method for determining the arrangement points of multiple fixing components 300 (i.e., pipeline support points) is: arranging them along the direction of the river 100, with the distance between adjacent fixing components 300 being d, d≤3500mm; the purpose of limiting the spacing between adjacent fixing components 300 is to reasonably control the arrangement density of the fixing components 300, so that the sewage interception pipeline 200 can be reliably fixed while reducing construction costs.

[0052] Furthermore, in order to enable the liquid phase in the sewage interception pipe 200 to be discharged smoothly, the sewage interception pipe 200 should have a certain slope as a whole. For example, the slope of the sewage interception pipe 200 is 0.1%-0.3%; accordingly, the elevation settings of the multiple fixed components 300 should meet the slope requirements of the sewage interception pipe 200.

[0053] For example, assuming that the total length of the sewage interception pipeline 200 is 1000m, the distance between adjacent fixed components 300 is d=3500m, and the slope of the sewage interception pipeline 200 is 3%; the elevation of the starting point (i.e., the first fixed component 300) is H 0, then the elevation of the nth fixed component 300 H n for:

[0054]

[0055] in, is the elevation difference between adjacent fixing assemblies 300 .

[0056] S200, setting a fixing assembly 300 at a corresponding pipeline support point; In this embodiment, after determining the pipeline support point, the method of setting the fixing assembly 300 at the corresponding pipeline support point includes the following steps: S210, installing a concrete pier fixing member 320 at the pipeline support point; Furthermore, the method of setting the concrete pier fixing member 320 at the pipeline support point includes the following steps: S211. Manually driving multiple anti-corrosion steel bars as first fixing members 321 in a direction perpendicular to the ground (i.e., vertical direction); Specifically, the number of the first fixing members 321 is two, and each first fixing member 321 is composed of multiple sections of anti-corrosion steel bars, and the multiple sections of anti-corrosion steel bars are connected by a steel bar connector 323.

[0057] S212, manually driving a plurality of steel bars as second fixing members 322 in a direction perpendicular to the soil slope 110; Specifically, the number of second fixing members 322 is two, and each second fixing member 322 is composed of multiple sections of anti-corrosion steel bars, and the multiple sections of anti-corrosion steel bars are connected by steel bar connectors 323.

[0058] In this embodiment, the first fixing member 321 and the second fixing member 322 are made of anti-corrosion steel bars with a diameter of not less than 28 mm; at the same time, the length of each steel bar is , exemplary, It can be 0.5m, 1m, or 1.5m; the total length of the connected steel bars (ie, the total length of the first fixing member 321 and the second fixing member 322) is L, L≥3m, and for example, L can be 3m, 4m, or 5m.

[0059] S220, excavating a plane at the pipeline support point, and pouring concrete at the plane to form a concrete pier 310; In this embodiment, the method of excavating a plane at a pipeline support point and pouring concrete at the plane to form a concrete pier 310 includes the following steps: S221. Mark the excavation plane and control the excavation plane area S for: S≥(D+150)×500 Wherein, D is the outer diameter of the sewage interception pipe 200.

[0060] S222, plane manual excavation; In this embodiment, the method of plane manual excavation is a conventional earthwork manual excavation operation, which includes using a pickaxe to break up the hard soil layer after on-site investigation, shoveling the soil with a shovel, and transporting the soil to a designated stacking point.

[0061] S223 , pouring the concrete pier 310 , and making the height of the concrete pier 310 h, h≥500 mm.

[0062] In this embodiment, the method of pouring the concrete pier 310 is a conventional manual pouring method, including preliminary pouring construction preparation, template production and installation, base treatment, concrete mixing, concrete pouring, formwork removal and maintenance, etc.; it should be noted that during the pouring process, it is necessary to ensure that the first fixing member 321 and the second fixing member 322 are in the calibrated position in the concrete pier 310.

[0063] Furthermore, lightweight concrete is used for pouring the concrete pier 310 .

[0064] S300 , the sewage interception pipe 200 is set up on the corresponding fixing assembly 300 , and the sewage interception pipe 200 is connected to the corresponding fixing assembly 300 through the pipe fixing member 400 .

[0065] In this embodiment, the method of connecting the sewage interception pipe 200 with the corresponding fixing assembly 300 through the pipe fixing member 400 is: the arc structure of the third fixing member 410 is fitted with the outer wall of the sewage interception pipe 200, and the two ends of the arc structure are fixed to the concrete pier 310 through the fourth fixing member 420.

[0066] In the method for laying sewage interception pipes on earthen slopes in narrow rivers and creeks provided in this embodiment, both the concrete pier fixing parts 320 and the concrete pier 310 are manually driven in and cast, so that when construction machinery and equipment are difficult to enter, fixed points for fixing sewage interception pipes 200 can be provided on the earthen slopes 110 on both sides of the river and creek 100 to support the continuously installed sewage interception pipes 200; this effectively solves the problem of sewage interception of the sewage pipes 600 on the earthen slopes 110 on both sides of the narrow river and creek site, and achieves economical, safe, efficient, environmentally friendly, and green and feasible effects.
