Description

Technical Field

[0001] The invention relates to the technical field of protective tube shells, in particular to an environmentally friendly plastic semicircular protective tube shell. Background Art

[0002] Heat exchange tubes are buried one meter underground, and brick trenches are usually set up for protection and insulation. Brick trenches can provide physical protection for heat exchange tubes to prevent damage to pipes by hard objects such as stones and tree roots in the soil. At the same time, they can also resist a certain degree of external impact and extrusion. Brick trenches can maintain the flexibility of heat exchange tubes in the cavity; plastic protective sleeves can replace the role of brick trenches. Plastic protective sleeves and semi-circular tube structures can reduce the heat exchange between soil and heat exchange tubes, and play a protective and heat-insulating role. Plastic protective sleeve semi-circular tubes can extend the service life of heat exchange tubes and reduce pipeline failures and replacement requirements caused by factors such as wear; Summary of the invention

[0020] The embodiments of the present invention are described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] When paving existing heat exchange pipes, it is generally necessary to dig a trench first, then compact and make a concrete cushion (or reinforced concrete cushion), and then install the heat exchange pipes. After completing the pressure test process, the plastic semicircular protective pipe shell is buckled down and installed;

[0022] Therefore, the present application provides an environmentally friendly plastic semicircular protective tube shell, which can significantly reduce the production and installation costs, and can recycle waste plastics. Waste plastic waste that originally needed to be buried can be utilized and buried underground to protect and insulate the heat exchange pipe, thereby preventing the heat of the heat exchange pipe from being lost to the ground.

[0023] Specifically, the present application provides an environmentally friendly plastic semicircular protective tube shell, comprising vertical edges 1 on both sides and an arc-shaped top 2 on the top, the vertical edges 1 and the arc-shaped top 2 are integrally formed, the vertical edges 1 and the arc-shaped top 2 of the environmentally friendly plastic semicircular protective tube shell are integrally formed, the structure is compact, and the connection is reduced. The vertical edges 1 and the arc-shaped top 2 are pressed into a continuous semicircular tube shell, and the semicircular tube shell is integrally pressed by plastic. The plastic material has high corrosion resistance, can resist the erosion of various chemical substances, and prolongs the service life. Compared with concrete materials, plastic materials are lighter, easy to transport and install, and have relatively High strength, able to withstand a certain amount of pressure and impact, an opening is left on the lower side of the semicircular tube shell, the environmentally friendly plastic semicircular protective tube shell is light in material and reasonably designed, the installation process is simpler and faster, reducing the investment in manpower and material resources, the plastic material is not easy to corrode and age, and the maintenance frequency and cost are reduced. Although the initial investment may vary depending on the material and process, considering the long life and low maintenance cost of the plastic material, its overall cost-effectiveness is usually higher, and the convenience of installation and maintenance, the environmentally friendly plastic semicircular protective tube shell can shorten the construction period, improve construction efficiency and further reduce costs.

[0024] The semicircular tube shell forms a containing cavity, and a pipeline is arranged in the containing cavity, which provides a protective layer for the pipeline.

[0025] The plastic is waste plastic or recycled plastic. The environmentally friendly plastic semicircular protective tube shell is made of plastic material, which usually has the advantages of being harmless to the human body, corrosion-resistant, and having a small thermal conductivity, and meets modern environmental protection requirements.

[0026] The radius of the arc-shaped top 2 is 1 / 2 of the spacing of the vertical edges 1. The structure of the entire semicircular pipe shell will become very compact, saving materials and reducing the occupied space, so that the pipe shell can play a more effective role in a limited space. The compact structural design enables the pipe shell to fit more closely to the soil when buried, reducing the gap between the soil and the pipe, thereby improving the stability and thermal insulation performance of the pipe. The design of the arc-shaped top 2 can more evenly distribute the pressure from the soil or the outside, avoiding damage to the pipe caused by stress concentration. Due to the smooth transition between the arc-shaped top 2 and the vertical edge 1, there is no need for excessive adjustment and alignment during the installation process, which improves the installation efficiency.

[0027] The thickness of the semicircular tube shell is 10-25mm. Within this thickness range, the tube shell can be ensured to have sufficient strength and rigidity to withstand soil pressure, external impact and extrusion, and protect the internal pipeline from damage. Appropriate thickness helps to achieve a tight connection between the tube shells and reduce the risk of leakage.

[0028] The height of the vertical side 1 is equal to the radius of the arc-shaped top 2. The symmetrical structural design can more evenly distribute the pressure from the soil or the outside, avoiding damage to the pipe caused by stress concentration. The height of the arc-shaped top 2 is equal to the height of the vertical side 1, so that the pipe shell can maintain overall stability when under pressure and is not prone to deformation or damage.

[0029] The length of the semicircular tube shell is 1000-6000mm, which makes the semicircular tube shell flexibly applicable to a variety of scenarios. Whether it is a short-distance pipeline connection or a long-span pipeline laying, the appropriate tube shell size can be found, and the semicircular tube shell made of plastic can also be easily cut to adjust the installation.

The shell thickness is 10 mm, the length of a single shell is 1000-4000 mm, and the cross-section of the shell is an arch. In the cross-section, the radius of the arc-shaped top 2 is 75 mm, the height of the vertical edges 1 on both sides is 55 mm, and the distance between the two vertical edges 1 is 150 mm.

[0034] Embodiment 5. This embodiment provides an environmentally friendly plastic semicircular protective tube shell. The shell thickness is 25 mm, the length of a single shell is 6000 mm, and the cross-section of the shell is an arch. In the cross-section, the radius of the arc-shaped top 2 is 125 mm, the height of the vertical edges 1 on both sides is 125 mm, and the distance between the two vertical edges 1 is 250 mm.

[0035] During installation, it is generally necessary to dig a trench first, set a concrete (or reinforced concrete) cushion layer 4 at the bottom of the trench, lay pipes on the cushion layer 4, invert an environmentally friendly plastic semicircular protective pipe shell on the pipe, set limiting ribs 3 on both sides of the environmentally friendly plastic semicircular protective pipe shell, and then backfill the cushion layer 4, the limiting block 3 and the environmentally friendly plastic semicircular protective pipe shell.

[0036] In the traditional scheme, it is generally necessary to dig a trench first, make a concrete cushion at the bottom of the trench, build the trench wall with bricks on both sides of the concrete cushion to form a pipe trench, and then lay the heat exchange pipe in the pipe trench, and then cover the upper part of the pipe trench with a reinforced concrete cover plate, and then carry out the soil covering process and ground restoration work. The cost per meter needs to reach 200-300 yuan. In this application, waste plastic pipe sleeves and cement base are innovatively used, and the cost per meter is about 80-120 yuan, which can reduce the cost by 40%-60%;

[0037] In the traditional scheme, the construction period is also very long, which takes 7-14 days. However, the innovative use of waste plastic pipe sleeves in this application only takes 1-3 days, shortening the construction period by 50%-70%.

[0038] In traditional solutions, the bricklaying process is a high-carbon emission process, while the recycling of waste materials can reduce carbon emissions. In addition, the traditional solution has low construction flexibility, and workers need to rely on large machinery and have high site requirements during construction, and require lifting and other processes. In this application, only a small amount of manpower is required for installation, and construction is more flexible in narrow or complex terrain.
