Description

Technical Field

[0001] The invention relates to the technical field of drainage pipe construction, and in particular to a reinforcement and installation method for anti-buoyancy of concrete encapsulation of rainwater and sewage pipes. Background Art

[0002] At present, in the field of municipal construction and water supply and drainage construction of housing construction, the traditional rain and sewage mixed flow drainage ditch has gradually failed to meet the sewage and rainwater discharge of people's daily life, and does not meet the environmental protection requirements of today's modern society. Therefore, in the field of municipal construction, housing construction and renovation of old communities, rain and sewage separation and underground pipes have become the mainstream, and the construction volume is also gradually increasing.

[0003] The shortcomings of existing pipeline construction can be summarized as follows: First, the bending of pipelines caused in pipeline transportation projects leads to uneven installation and affects the apparent quality; second, rainwater and sewage pipes are usually plastic corrugated pipes with a light texture. When pouring encapsulated concrete, it is easy to cause the pipeline to float, affecting the determined elevation and drainage slope, and easily causing substandard on-site quality, rework or poor drainage, and even drainage backflow and backflow; third, when pouring pipe encapsulated concrete, if strong means are used to resist floating, it is very likely to cause pipeline damage or poor apparent quality; fourth, during the construction process, if other external forces are used to repair the pipeline, it will cause a significant decrease in construction efficiency, a lot of waste of manpower and material resources, and poor timeliness.

[0004] There are many technical solutions for the anti-floating installation of pipelines, such as the Chinese patent with publication number CN 221001311U, which discloses a mounting structure for fixing pipelines by setting steel support brackets in pipe grooves; another example is the Chinese patent with publication number CN117702883A, which discloses a method for connecting and installing pipelines by setting connecting components between rainwater and sewage pipes. These solutions require the use of relatively complex structural parts or equipment, with high construction costs and low construction efficiency. Summary of the invention

[0005] In order to overcome the above-mentioned deficiencies existing in the existing installation process of rainwater and sewage pipes, the technical problem to be solved by the present invention is to provide a reinforcement installation method for rainwater and sewage pipe concrete encapsulation anti-buoyancy with low cost and high construction efficiency.

[0006] The technical solution adopted by the present invention to solve its technical problem is:

[0007] The reinforcement and installation method for anti-buoyancy of rainwater and sewage pipe concrete encapsulation includes the following steps:

[0008] Step 1: Dig a pipe trench of appropriate size according to the design drawings and specification requirements, and then pour a concrete cushion layer at the bottom of the pipe trench according to the pipe bottom elevation;

[0009] Step 2: Arrange fixings on the concrete cushion layer. The fixings are located on both sides of the pipeline laying position and are arranged at intervals along the extension direction of the pipeline. The positions of the fixings on both sides correspond to each other.

[0010] Step 3: Connect fasteners between corresponding fixings on both sides of the pipeline, set a pressure plate on the outer wall of the pipeline, and use the clamping force of the fasteners on the pressure plate to fix the pipeline on the concrete cushion layer;

[0011] Step 4: Pour pipe encapsulating concrete.

[0012] Furthermore, the fixing piece is an iron nail driven into the concrete cushion layer.

[0013] Furthermore, the fixing member is an inverted V-shaped or N-shaped steel bar embedded in the concrete cushion layer.

[0014] Furthermore, the fastener is a wire, a strap or a rope.

[0015] Furthermore, the pressing plate is a wooden board or a plastic board.

[0016] Furthermore, when the fixing parts are arranged in step 2, a fixing part is arranged at intervals of 1.5-2 m along the extending direction of the pipeline.

[0017] Furthermore, when the fixing members are arranged in step 2, if there are multiple pipes in the pipe groove, adjacent pipes share a row of fixing members.

[0018] Furthermore, when setting the pressure plates in step three, three pressure plates are set corresponding to each fastener, which are respectively located on the left and right sides and the top of the pipeline.

[0019] Furthermore, the length and width of the pressing plate are not less than 10 cm.

[0020] The beneficial effects of the present invention are as follows: by firstly setting fixings at the bottom of the pipe grooves on both sides of the pipeline, then setting pressure plates on the side walls of the pipeline, and finally using fasteners tied between the fixings to tighten the pressure plates, the pipeline is fixed. The entire construction process is simple to operate and low in cost. It can play a good anti-floating role for the pipeline during concrete pouring and will not cause damage to the pipeline, thereby improving the construction efficiency and installation accuracy of the pipeline.

[0023] The present invention is further described below in conjunction with the accompanying drawings.

[0024] It should be noted that if there are directional indication terms in the present invention, such as up, down, left, right, front, and back directions and orientation terms, they are for the purpose of facilitating the description of the relative position relationship between components, and are not specific to the absolute position of the related components or the position relationship between components. They are only used to explain the relative position relationship and movement of the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly. If there are terms related to quantity in the present invention, such as "multiple", "multiple", "several", etc., they specifically refer to two or more.

[0025] The present invention provides a method for reinforcing and installing a rainwater and sewage pipe concrete encapsulation to resist buoyancy, comprising the following steps:

[0026] Step 1: excavate a pipe trench 1 of appropriate size according to the design drawings and specification requirements, and then pour a concrete cushion layer 2 at the bottom of the pipe trench 1 according to the pipe bottom elevation;

[0027] Step 2: Arrange the fixing members 3 on the concrete cushion layer 2. The fixing members 3 are located on both sides of the laying position of the pipeline 4 and are arranged at intervals along the extending direction of the pipeline 4. The positions of the fixing members 3 on both sides correspond to each other.

[0028] Step 3: Connect the fasteners 5 between the corresponding fixing members 3 on both sides of the pipe 4, set a pressing plate 6 on the outer wall of the pipe 4, and fix the pipe 4 on the concrete cushion layer 2 by using the clamping force of the fasteners 5 on the pressing plate 6;

[0029] Step 4: Pour the pipe encapsulating concrete.

[0030] After installation, the structure is as follows Figure 1 As shown, compared with the traditional solution that requires a complex auxiliary structure to be set in the pipe groove 1 to fix the pipe 4, the present application adopts a simple fixing member 3 and a fastener 5 to fix the pipe 4 by tightening, which is simple and convenient, can be applied to any scene, and has a stable and reliable anti-floating effect. The function of the pressure plate 6 is to disperse the tightening force of the fastener 5 to prevent the fastener 5 from directly acting on the pipe 4 to cause damage or deformation. When setting the pressure plate 6, it is not necessary to fix it on the pipe 4 in advance, but only to insert it between the fastener 5 and the pipe 4 during the process of tightening the fastener 5.

[0031] Regarding the specific structure of the fixing member 3, the present application provides two methods. One is that the fixing member 3 is an iron nail driven into the concrete cushion layer 2. Its advantage is convenience and speed, but its disadvantage is the risk of loosening. The other is that the fixing member 3 is an inverted V-shaped or N-shaped steel bar embedded in the concrete cushion layer 2. This method requires that the steel bar be placed before pouring the concrete cushion layer 2, and waste steel bars on site can be used. Its advantage is stability and reliability, but its disadvantage is that the construction process is more cumbersome.

[0032] The fastener 5 can be a flexible piece such as a wire, a strap or a rope, so as to tighten the pipeline by tensioning force.

[0033] The pressing plate 6 can be made of a wooden board or a plastic board, wherein a wooden board is preferred, which has a certain flexibility, and the length and width of the pressing plate 6 are preferably not less than 10 cm, so as to better disperse the force from the fastener 5.

[0034] During the specific construction, the flexibility of the pipeline 4 is taken into consideration. To ensure the anti-floating effect, when the fixing parts 3 are laid out in step 2, it is best to lay out a fixing part 3 every 1.5-2m along the extension direction of the pipeline 4. If the fixing parts 3 are too dense, they are easy to be over-positioned, resulting in a waste of resources. If they are too scattered, the pipeline 4 between adjacent fixing parts 3 may be deformed due to buoyancy. After testing, it is found that laying out a fixing part 3 every 1.5-2m can take into account both cost and positioning requirements. In addition, if there are multiple parallel pipelines 4 in the pipe groove 1, a row of fixing parts 3 can be set in the middle of the adjacent pipelines 4 for sharing by two adjacent pipelines 4, thereby saving costs.

[0035] When setting the pressing plates 6 in step 3, only three pressing plates 6 are required for each fastener 5, which are respectively located on the left and right sides and the top of the pipe 4. Since the buoyancy generated by the concrete is not large, the fastener 5 does not require too much tension, so only three pressing plates 6 are required to prevent the fastener 5 from directly acting on the pipe 4 over a large range.

[0036] The present invention first sets fixing members 3 at the bottom of the pipe groove 1 on both sides of the pipe 4, then sets pressure plates 6 on the side walls of the pipe 4, and finally uses fasteners 5 tied between the fixing members 3 to clamp the pressure plates 6, so as to fix the pipe 4. The whole construction process is simple to operate and low in cost. It can play a good anti-floating role for the pipe 4 during the concrete pouring process without causing damage to the pipe 4, thereby improving the construction efficiency and installation accuracy of the pipe 4, having good practicality and application value, and is particularly suitable for the renovation projects of some old communities.
