Description

Technical Field

[0001] The present invention relates to the technical field of drainage ditch construction, and particularly relates to a cyclic construction method for an engineering temporary drainage ditch. Background Art

[0002] During the construction of a building project, it is often necessary to build a temporary drainage ditch at the construction site to organize the drainage of rainwater, domestic water, and production water during construction to the outside of the site, so as to ensure that there is no water accumulation in the construction site area and ensure the construction quality.

[0003] Traditionally, the engineering temporary drainage ditch is formed by masonry with bricks and cement mortar, which is costly, has a long construction period, affects the project progress, is inconvenient to demolish later, and can only be used once, resulting in serious waste of labor and materials, and does not conform to the concept of green environmental protection.

[0004] In recent years, PE drainage ditches are also often used for engineering temporary drainage ditches. It is a drainage ditch made of plastic material, and its use and scope of application are no different from other drainage ditches. However, it is inexpensive, can reduce the budget requirements, and the construction is simple. The PE drainage ditch is assembled and used piece by piece, saving the cumbersome traditional bricklaying, saving time and effort, and being easy to control the construction period.

[0005] However, during actual operation, the PE drainage ditch often suffers from inward extrusion or outward deformation at the interface due to reasons such as soil settlement on both sides, as well as trampling by vehicles and personnel, resulting in offset, leakage, or even irreparable damage at the interface of the drainage ditch, and the purpose of recycling and reuse cannot be achieved. Summary of the Invention

[0006] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a cyclic construction method for an engineering temporary drainage ditch, which can protect the interface part of the drainage ditch, prevent inward extrusion and outward deformation at the interface of the drainage ditch during operation, avoid offset, leakage, or damage at the interface, contribute to the recycling and reuse of the PE drainage ditch, and achieve the purpose of green environmental protection.

[0007] The purpose of the present invention is achieved by adopting the following technical solutions:

[0008] A cyclic construction method for an engineering temporary drainage ditch includes the following steps:

[0009] Construction step:

[0010] Excavate a trench according to the pre-planned drainage ditch laying route;

[0011] Pour a concrete cushion along the trench, and the concrete cushion is located at the middle position of the bottom surface of the trench;

[0012] Lay PE drainage ditches on the concrete cushion, and splice between individual PE drainage ditches through the interfaces of the two;

[0013] Install a prefabricated drainage ditch interface reinforcement component at the interface of the PE drainage ditch. The prefabricated drainage ditch interface reinforcement component includes a horizontal support rod, an L-shaped limiting member, and a ground-inserting support rod. There are two L-shaped limiting members, which are respectively located at both ends of the horizontal support rod. The L-shaped limiting member includes a top limiting plate and an inner limiting plate that are perpendicular to each other, and the top limiting plate is located on the top side of the inner limiting plate. The horizontal support rod is perpendicular to the inner limiting plate and fixedly connected to it. A limiting through-hole is opened on the top limiting plate, and the ground-inserting support rod is inserted inside the limiting through-hole. The ground-inserting support rod is separated from the inner limiting plate, and the ground-inserting support rod is located on the side of the inner limiting plate facing away from the horizontal support rod;

[0014] Carry out filling operation on the area between the outside of the PE drainage ditch and the inside of the trench;

[0015] After the filling operation is completed, pour concrete slopes on the soil surfaces on both sides of the PE drainage ditch;

[0016] Demolition and recycling steps:

[0017] Demolish the concrete slope and excavate the soil on both sides of the PE drainage ditch;

[0018] Dismantle and recycle the prefabricated drainage ditch interface reinforcement component;

[0019] Dismantle and recycle the PE drainage ditch.

[0020] Further, in the step of installing the prefabricated drainage ditch interface reinforcement component at the interface of the PE drainage ditch, it is necessary to make the two L-shaped limiting members of the prefabricated drainage ditch interface reinforcement component respectively overlap on both side edges of the top of the PE drainage ditch, and the L-shaped limiting member is located at the interface of the PE drainage ditch, so that the inner limiting plate limits the inner side of the interface of the PE drainage ditch, and the ground-inserting support rod limits the outer side of the interface of the PE drainage ditch.

[0021] Further, in the step of installing the prefabricated drainage ditch interface reinforcement component at the interface of the PE drainage ditch, it is also necessary to make the ground-inserting support rod avoid the concrete cushion and nail it into the bottom surface of the trench.

[0022] Further, the inner limiting plate and the horizontal support rod are fixedly connected by welding.

[0023] Further, the ground-inserting support rod and the limiting through-hole form a clearance fit.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] The cyclic construction method of the temporary engineering drainage ditch provided by the present invention includes a construction step and a demolition and recycling step. In the construction step, a prefabricated drainage ditch interface reinforcement component is installed at the interface of the PE drainage ditch, which can protect the interface part of the drainage ditch, prevent inward extrusion and outward deformation at the interface of the drainage ditch during operation, avoid offset, leakage or damage at the interface, and contribute to the recycling and reuse of the PE drainage ditch, achieving the purpose of environmental protection.

[0037] S103. Lay a PE drainage ditch on the concrete cushion, and splice individual PE drainage ditches through the interfaces between them.

[0038] S104. Install a prefabricated drainage ditch interface reinforcement component at the interface of the PE drainage ditch; refer to Figure 2 , the prefabricated drainage ditch interface reinforcement component includes a horizontal support rod 1, an L-shaped limiting member 2 and a ground-inserting support rod 3. There are two L-shaped limiting members 2 which are respectively located at both ends of the horizontal support rod 1. The L-shaped limiting member 2 includes a top limiting plate 21 and an inner limiting plate 22 which are perpendicular to each other, and the top limiting plate 21 is located on the top side of the inner limiting plate 22. The horizontal support rod 1 is perpendicular to the inner limiting plate 22 and fixedly connected to it. A limiting through hole 23 is opened on the top limiting plate 21. The ground-inserting support rod 3 is inserted inside the limiting through hole 23. The ground-inserting support rod 3 is separated from the inner limiting plate 22, and the ground-inserting support rod 3 is located on the side of the inner limiting plate 22 facing away from the horizontal support rod 1.

[0039] S105. Carry out filling operation on the area between the outside of the PE drainage ditch and the inside of the trench.

[0040] S106. After the filling operation is completed, pour a concrete slope on the soil surfaces on both sides of the PE drainage ditch for drainage slope finding.

[0041] S200. Demolition and recycling steps:

[0042] S201. Demolish the concrete slope and excavate the soil on both sides of the PE drainage ditch.

[0043] S202. Dismantle and recycle the prefabricated drainage ditch interface reinforcement component.

[0044] S203. Dismantle and recycle the PE drainage ditch.

[0045] S204. After the materials are recycled, dismantle the concrete cushion and backfill the soil.

[0046] Preferably, in step S104, for the used prefabricated drainage ditch interface reinforcement component, the inner limiting plate 22 and the horizontal support rod 1 are fixedly connected by welding; the ground-inserting support rod 3 and the limiting through hole 23 form a clearance fit.

[0047] Refer to Figure 3 、 Figure 4 And Figure 5 , install a prefabricated drainage ditch interface reinforcement component at the interface of the PE drainage ditch. In this step, it is necessary to make the two L-shaped limiting members 2 of the prefabricated drainage ditch interface reinforcement component respectively overlap on both sides of the top of the PE drainage ditch 4, and the L-shaped limiting member 2 is located at the interface of the PE drainage ditch 4, so that the inner limiting plate 22 limits the inside of the interface of the PE drainage ditch 4, and the ground-inserting support rod 3 limits the outside of the interface of the PE drainage ditch 4.

[0048] Preferably, a prefabricated drain gutter interface reinforcement component is installed at the interface of the PE drain gutter. In this step, it is also necessary to avoid the concrete cushion layer with the ground insertion support rod 3 and drive it into the bottom surface of the trench.

[0049] Preferably, male interfaces 41 and female interfaces 42 are respectively arranged at both ends of a single PE drain gutter 4. The single PE drain gutters 4 are spliced in pairs through the male interfaces 41 and the female interfaces 42.

[0050] For the engineering temporary drain gutter cyclic construction method provided by the embodiment of the present invention, during the process of building the drain gutter, a prefabricated drain gutter interface reinforcement component is installed at the interface of the PE drain gutter, which can protect the interface part of the PE drain gutter. The specific principle is as follows:

[0051] The transverse support rod 1 can provide lateral support force for the two L-shaped limit members 2. During installation, the two L-shaped limit members 2 can be directly lapped on both sides of the top of the PE drain gutter, and the L-shaped limit members 2 are located at the interface of the PE drain gutter; since the ground insertion support rod 3 is separated from the inner limit plate 22, and the ground insertion support rod 3 is located on the side of the inner limit plate 22 facing away from the transverse support rod 1, the inner limit plate 22 and the ground insertion support rod 3 can be respectively located inside and outside the interface of the PE drain gutter, so as to protect the interface part of the PE drain gutter; wherein, the inner limit plate 22 is used for inner limit of the interface of the PE drain gutter to prevent the interface from being squeezed inward, and the ground insertion support rod 3 is used for outer limit of the interface of the PE drain gutter to prevent the interface from deforming outward, so as to avoid offset, water leakage or damage at the interface of the PE drain gutter, thereby facilitating the recyclability of the PE drain gutter and achieving the purpose of cyclic use and environmental protection.

[0052] For the engineering temporary drain gutter cyclic construction method provided by the embodiment of the present invention, since the ground insertion support rod is driven into the bottom surface of the trench, after the trench is filled with soil, the ground insertion support rod will become very firm, which can not only play a role in limiting the outside of the interface of the PE drain gutter, but also prevent the overall offset of the PE drain gutter; moreover, the ground insertion support rod also has the function of reinforcement and anti-offset during the process of filling the trench with soil.

[0053] The engineering temporary drain gutter cyclic construction method provided by the embodiment of the present invention gives specific construction steps and demolition and recycling steps, and provides the whole process of cyclic use of the PE drain gutter and the prefabricated drain gutter interface reinforcement component.

[0054] The prefabricated drainage ditch interface reinforcement component used in the cyclic construction method of the temporary engineering drainage ditch provided by the embodiments of the present invention can be made of common L-shaped steel (corresponding to the L-shaped limiting member), flat steel (corresponding to the horizontal support rod), and steel bar column (corresponding to the ground-inserted support rod). The materials are inexpensive and easy to obtain, and can basically be self-made in ordinary projects; moreover, the installation process of the prefabricated drainage ditch interface reinforcement component is also very simple.

[0055] The above-mentioned implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
