Hot-melting bonding guide pipe type plastic drainage plate

Abstract

The invention discloses a hot-melting bonding guide pipe type plastic drainage plate. The hot-melting bonding guide pipe type plastic drainage plate comprises a plastic core plate and a water-permeable filter film wrapping the outer side of the plastic core plate. A drainage groove is formed in the plastic core plate. A center guide pipe used for increasing the overall discharge capacity of the drainage plate, improving the overall strength of the drainage plate and expanding the use function of the drainage plate is arranged in the middle of the plastic core plate. Evenly-distributed water-permeable holes are formed in the pipe wall of the center guide pipe. The water-permeable filter film and the plastic core plate are bonded into a whole through the hot-melting bonding process. According to the hot-melting bonding guide pipe type plastic drainage plate, the phenomenon of poor drainage and even drainage plate failures caused by clogging is solved, and the work efficiency of the drainage plate is effectively improved; and in addition, through the additionally-arranged center guide pipe, the discharge capacity in unit time of the drainage plate is increased, the solidification timeis shortened, meanwhile, the function of the drainage plate is expanded, and the drainage plate can double as a tool for soil foundation aftertreatment.

Description

technical field [0001] The invention relates to the field of geotechnical engineering, in particular to a hot-melt bonding duct-type plastic drainage board. Background technique [0002] In the soft foundation reinforcement project, the commonly used drainage board is composed of a plastic core board covered with a filter membrane. The plastic core board is provided with a drainage channel, and the mesh between the non-woven fibers forms a permeable filter membrane. During construction, the plastic drainage board is inserted into the saturated viscous soft foundation such as silt, silty soil, and flushing soil through the inserting machine. Drain channels drain into the upper bedding sand layer or horizontal plastic drains and out elsewhere. As the air and water in the filter membrane are continuously discharged, the air pressure difference inside and outside the filter membrane gradually increases, and the water vapor in the foundation is continuously discharged to achieve...
