Production equipment for plastic drainage strips

Abstract

The invention discloses production equipment for plastic drainage strips. The equipment comprises a driving device, and also comprises a feeding device, a pressing device and a winding device from end to end in turn, wherein a plurality of groups of raw materials are parallelly arranged in the feeding device; each group of raw material comprises a core plate coil (5), an upper filter membrane coil (7) and a lower filter membrane coil (21); and the driving device is connected with and drives the pressing device. After the structure is adopted, the plurality of groups of raw materials are parallelly arranged in the feeding device, namely a plurality of drainage strips can be produced at one time simultaneously, so that production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of mechanical equipment, specifically a production equipment for plastic drainage belts. Background technique [0002] Plastic drainage belt is a commonly used soft ground treatment material. Its middle layer is an extruded plastic core board, which is the skeleton and channel of the drainage belt. Its cross-section has various shapes such as wave shape and harmonica shape. Both sides are wrapped with non-woven geotextile as filter membrane. Usually, the plastic drainage belt is inserted into the soft soil foundation with a plug-in machine. Under the action of the upper preload, the interstitial water in the soft soil foundation is discharged from the plastic drainage belt to the upper sand layer or horizontal plastic drainage pipe, and is drained by other places. Drain and consolidate with soft ground. The production equipment of the plastic drainage belt in the prior art is to bond the fused filter membrane on the...

AI Technical Summary

Problems solved by technology

[0003] 1) It is only suitable for the production of a single drainage belt, that is, only two sides of a core board can be bonded to the filter membrane at a time, so the production efficiency is low;

[0004] 2) In addition, the plastic drainage belt produced by this production equipment is made of two kinds of fibers with high melting point and low melting point because the filter membranes on both sides are combined. The low melting point fiber has low tensile strength and high elongation. This kind of filter membrane is easy to be pressed into the groove of the core plate, thereby blocking the channel of the core plate, affecting the water flow of the core plate, and making it difficult to discharge the water in the soft ground
