Heating-type plastic drainage plate and construction method thereof

Abstract

The invention discloses a heating-type plastic drainage plate and a construction method thereof. The heating-type plastic drainage plate comprises a core plate and a filter membrane, wherein the coreplate is coated with the filter membrane; and an electric heating membrane is packaged in the core plate. The heating-type plastic drainage plate disclosed by the invention is reasonable in design andsimple in structure; the electric heating membrane is packaged in the core plate of the heating-type plastic drainage plate, so that the heating-type plastic drainage plate can have the electric heating function on the basis that the own drainage function of the heating-type plastic drainage plate is not influenced; the heating structure of the heating-type plastic drainage plate is high in sealing performance and waterproof grade; furthermore, the heating-type plastic drainage plate has the advantages that the construction is simple and the connection is convenient; and the temperature of asoil body in a smear zone around the adopted heating-type plastic drainage plate is increased, the consolidation drainage rate is improved, and the consolidation time is shortened.

Description

technical field [0001] The invention belongs to the field of civil engineering geotechnical synthetic materials, and in particular relates to a heated plastic drainage board and a construction method thereof. Background technique [0002] Drainage consolidation method is widely used in soft clay foundation treatment. In order to shorten the drainage path and reduce the consolidation time, vertical plastic drainage boards need to be driven into the foundation. The plastic drainage board is a strip-shaped composite structure, and the middle is an extruded plastic core board, generally made of high-density polyethylene (HDPE), which is the skeleton and channel of the drainage board, and its cross-section is parallel cross. The two sides of the core board are wrapped with non-woven geotextile as filter layer. The plastic drainage board is generally inserted into the casing first, and the casing is driven into the specified depth through the plugging machine, and then the casin...

AI Technical Summary

Problems solved by technology

In the indoor test, methods such as arranging electric heating wires inside the groove of the core board of the plastic drainage board are generally used. The length is fixed, and the energy consumption is relatively high, so it is not suitable for large-scale on-site construction. A heating-type plastic drainage board suitable for on-site plugging machine construction and with high heating efficiency
