Installation method of plum blossom pipe Characteristics of plum blossom pipe
Plum blossom pipe is a kind of building material, which is made of pvc particles as the main material and other formulas through a unique mold. Plum blossom pipe is a kind of plum blossom-shaped connecting pipe, also known as plum blossom pipe and honeycomb pipe. The inner wall of this tube is smooth, and the optical cable can be directly threaded, which can save working hours, reasonable structure, high use value and long service life. Next, Bian Xiao introduces the installation method and characteristics of plum blossom pipe.

Installation method of plum blossom pipe

1. According to the design requirements and construction operation, the buried trench of the pipeline should be as straight as possible. If the bottom of the ditch is uneven, you can spread a layer of fine sand. Before burying the pipe, the hard objects in the ditch should be removed to prevent the pipe from being deformed. At the beginning of pipe burying, a porous pipe of 10- 15CM should be reserved in the manhole for cables to penetrate. The exposed sub-pipes at manhole ends shall be blocked by pipes. It is forbidden to mix sand and foreign matter into the pipe when burying it.

2. When connecting the pipes, place the tubular positioning rib upward, clean the outer wall of the end pipe, directly insert the socket at one end, put a thick board on the end face, and beat the board with a hammer to make the pipe socket in place. Directly socket at the other end, directly insert another pipe and socket in place, and then postpone it to the next manhole. In actual construction, the length of each plum blossom pipe is not necessarily the same as the length between manholes. In this case, measure the length of the pipeline according to the actual length of the manhole and cut it with a hacksaw, so it must be sawed neatly. After the docking is completed, the end extending into the manhole should be plugged with a pipe plug to prevent foreign objects from invading.

3. For those who install and use this product for the first time, do not backfill the soil before laying the first paragraph "Distance between two manholes". Try to open one or two holes with cable threading device, and then lay the next section after threading smoothly, which will be more reassuring.

4. After the pipeline is laid, backfill it with fine sand or fine soil to the height of the pipeline, and then backfill other soil. It is forbidden to use large stones or dry clods.

5. When the pipeline passes through a section severely damaged by external force, the hole connection part shall be covered with cement concrete to ensure its absolute safety.

Characteristics of plum blossom tube

The plum blossom pipe adopts porous integrated structure, which has good rigidity and uniform stress. The friction coefficient of the inner wall of the product is small, the cable is light, and the construction is simple and easy. There are multiple holes, which can reserve pipe holes and improve the utilization rate of communication holes. The product has a wide temperature range (+80-40) and can be used in tropical and cold regions. The joint adopts socket structure. The connection between pipelines can be completed without any tools, which is convenient for construction and maintenance. The service life of plum blossom pipe under the condition of buried depth is more than 30 years. Performance indicators The color of the pipe is uniform and consistent, and the color is white. Other colors can be customized according to user requirements. The pipe is smooth and uniform, with uniform color and no defects such as deformation and distortion. Cracks, breakage and perforation are not allowed in the inner and outer pipe walls. Marks should be durable and easy to identify.

Advantages of seven-hole plum blossom pipe products

1 7 Kong Meihua pipe is made of polyethylene (PE) or polyvinyl chloride (PVC), which has excellent low-temperature resilience, bending resistance, pressure resistance and impact resistance.

2. Seven-hole plum blossom pipe adopts multi-hole integrated layout, with good rigidity and uniform stress.

3. The friction coefficient of the inner wall of the seven-hole plum blossom pipe is small, the cable threading is light and handy, and the construction is simple and easy.

4. Seven Kong Meihua pipes have multiple holes, which can be reserved to improve the utilization rate of connected holes.

5. Seven-hole plum blossom pipe can be used in tropical and ice-cold areas with large temperature range (80-40).

6. Socket layout is selected for Kong Meihua pipe joint. The connection between pipelines can be completed without anything, which is convenient for construction and maintenance.

7. The service life of Kong Meihua pipe is more than 30 years under the condition of buried depth.
