[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0028] See also Figure 1 , a supplementary support structure for municipal pipeline engineering pipelines provided by an embodiment of the utility model is now described. The supplementary support structure for municipal pipeline engineering pipelines of this embodiment includes two support pile bodies 1 arranged at intervals, at least two transverse steel bodies 2 arranged at intervals, a plurality of vertical steel bodies 3 arranged at intervals, and a geotextile 5. The two support pile bodies 1 are used to support the side walls of the foundation pit through which the existing pipeline 6 passes; the left and right ends of each transverse steel body 2 are respectively welded to the two support pile bodies 1; the upper and lower ends of each vertical steel body 3 are respectively welded to the transverse steel bodies 2 on the upper and lower sides thereof; the geotextile 5 covers the support area formed by the transverse steel bodies 2 and the vertical steel bodies 3.

[0029] like Figure 1 As shown, for the side wall of the foundation pit through which the existing pipeline 6 passes, in the side wall area close to the existing pipeline 6, it is impossible to use the supporting pile body 1 to support the side wall of the foundation pit in this area. This embodiment forms a local support area by using a transverse steel body 2, a vertical steel body 3 and a geotextile 5 in this area, and encloses the side wall soil in the local support area, thereby effectively ensuring the safety of the foundation pit construction.

[0030] A supplementary support structure for municipal pipeline engineering pipelines according to an embodiment of the utility model can be used to provide supplementary support for pipeline intersections that are difficult to support with supporting piles 1. It can be supported as it is dug, and can be adjusted according to the length of the intersection, effectively playing a role of retaining soil and ensuring construction safety. A supplementary support structure for municipal pipeline engineering pipelines according to an embodiment of the utility model is not only applicable to situations where newly built pipelines intersect with existing underground pipelines, but also to situations where newly built pipelines intersect with ground poles or other obstacles, and has a wide range of applications. A supplementary support structure for municipal pipeline engineering pipelines according to an embodiment of the utility model only requires welding of steel sections and installation of geotextile mesh when in use, and there is no need to relocate the existing pipelines 6 in the trench (foundation pit). The construction is simple and easy to operate, while reducing construction costs.

[0031] Furthermore, a supplementary support structure for municipal pipeline engineering pipelines in an embodiment of the utility model further includes a plurality of U-shaped fixing ribs 4, and the plurality of U-shaped fixing ribs 4 are used to fix the geotextile 5 on the side wall of the foundation pit. Furthermore, the plurality of U-shaped fixing ribs 4 are evenly distributed at equal intervals on the support area covered by the geotextile 5 to achieve a better fixing effect on the geotextile 5. Specifically, the U-shaped fixing rib model can be 16HRB400.

[0032] Furthermore, the distance between the support pile body 1 and the core of the existing pipeline 6 (the core is the location of the central axis of the existing pipeline 6) is 1 to 2 meters. That is, the support pile body 1 can no longer be used for support within 1 to 2 meters on both sides of the core of the existing pipeline 6, and the supplementary support structure of this embodiment is used for support to ensure construction safety.

[0033] Furthermore, the supporting pile body 1 of the present embodiment is a steel sheet pile or a channel steel, which is easy to construct and can be reused.

[0034] Furthermore, the transverse steel body 1 of this embodiment is an angle steel. Specifically, the model of the angle steel can be 160×160×16. The angle steel is light in weight, has good supporting strength, and is flexible and convenient to construct.

[0035] Furthermore, the vertical steel body 2 of this embodiment is a steel bar. Specifically, the steel bar model can be 12HRB400. The steel bar also has good bearing strength and is flexible and convenient to construct.

[0036] Furthermore, the geotextile 5 of this embodiment has two fabrics and one membrane, and weighs 1000g / m 2 The geotextile has good durability and can play a good role in retaining soil.

[0037] When in use, a supplementary support structure for a municipal pipeline engineering pipeline according to an embodiment of the utility model can be installed according to the following steps:

[0038] The above-mentioned purpose of the utility model is achieved through the following technical solutions:

[0039] Step 1: According to the pipeline detection results and pipeline location, first use support piles 1 to support the areas outside the safety distance on both sides of the pipeline intersection (that is, the distance between the support piles 1 and the center of the existing pipeline 6 is 1 to 2 meters), and mark the locations of the crossing pipelines.

[0040] Step 2: Excavate the trench. When the excavation depth reaches about 1m, start welding the first and second horizontal steel bodies 2, and then weld the vertical steel body 3 between the two horizontal steel bodies 2. After the overall welding is completed, cover the geotextile 5 on the welded steel frame close to the soil side, and finally use U-shaped fixing ribs 4 to fix the geotextile 5.

[0041] Step 3: When the elevation of the designed pipeline is higher than the elevation of the existing pipeline 6 or the designed pipeline intersects with the ground pole line, repeat step 2, and support as you dig until the excavation reaches the designed elevation (i.e., the bottom line of the foundation pit excavation 7);

[0042] When the designed pipeline elevation is lower than the elevation of the existing pipeline 6, repeat step 2, and support as you dig until the excavation reaches the elevation of the existing pipeline 6. Use wire ropes or nylon ropes to suspend and reinforce the existing pipeline 6. After completion, continue to dig downwards and repeat step 2 until the excavation reaches the designed pipeline elevation (i.e., the foundation pit excavation bottom line 7).

[0043] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent.
