The plastic blind ditch is composed of a plastic core wrapped in a filter cloth outside the body. The plastic core is made of polypropylene (thermoplastic synthetic resin) as the main raw material, which is modified and hot melt extruded to form a three-dimensional network structure. Plastic core bodies have various structural forms such as rectangles, hollow rectangles, circular hollow, and circles. The main function is to collect and discharge water from the soil, reduce groundwater pressure, remove excess water, and protect the soil and buildings from damage caused by seepage deformation.
High water absorption, good drainage and permeability performance
The surface porosity is 85-97%, which is more than 5 times that of porous pipes and 3-4 times that of resin mesh pipes. The surface water absorption rate is high, and the collection and drainage performance is good.
High compressive strength
Due to its three-dimensional structure, its porosity is 80-95%, and its compressive performance is more than 10 times stronger than that of resin in pipe structures, with good compressive resistance.
Durable and durable
With anti-aging agent, it is acid and alkali resistant, UV resistant, anti-aging, durable, and can ensure long-term stability under water and in the middle of soil.
Good flexibility/lightweight
Compressive and flexible, suitable for construction in curves and other curved positions, and suitable for soil deformation.
Lightweight, easy to construct, customizable
Lightweight and convenient for construction. Diverse shapes and adaptability to construction requirements in complex environments.

1. Trenching and dredging:
To lay and install plastic blind pipes, it is first necessary to use an excavator to excavate a construction access road. After the construction of the access road is completed, dredging should be carried out from the middle to both ends of the road. The dredging thickness should be controlled within a certain range. It is important to remember to excavate a drainage ditch in the low-lying areas of the foundation during the dredging process that can discharge the accumulated water in the soft foundation, in order to discharge the accumulated water within the soft foundation range.
2. Laying geotextile:
After the dredging work is completed, the construction of the plastic blind ditch will begin. To reduce the accumulation of silt in the blind ditch, it is necessary to first lay geotextile in the plastic drainage blind ditch foundation pit, and then place larger sized stones at the bottom of the foundation pit. After the large stones are placed, small stones are placed. After the small stones are laid, crushed stones are placed at the top, and finally, they are rolled with a roller. After the rolling is completed, geotextile is laid.
3. Laying and installing plastic blind ditches:
A plastic drainage blind ditch should be laid every 30 meters horizontally, and a longitudinal drainage blind ditch should be constructed on the right side of the soft foundation to drain the water from the horizontal plastic blind ditch, effectively draining the surface and groundwater during construction, and reducing the impact of water on construction during roadbed filling. Construct a horizontal plastic drainage blind ditch in a sequence from the middle to both ends. After constructing the first horizontal drainage blind ditch, start throwing stones and squeezing silt towards both sides, squeezing out the silt towards both ends. After throwing stones for 30 meters, construct the second horizontal plastic drainage blind pipe.
