CLADDING METHOD AND METERIALS FOR EXTRACTING PILE FOR TEMPORARY RETAINING COALL

摘要

Provided is a coating agent for extracting pile for a temporary braced excavation wall, which prevents adhesion between concrete and the pile, imparts good release property to the pile and concrete, and allows the use of various types of steel-made materials such as H-type steel, steel pipes or sheets. The coating agent for extracting pile for a temporary braced excavation wall comprises: an anti-adhesion agent formed by mixing 40 wt% of a liquid vinyl resin with 60 wt% of methanol; and a coating film protective agent formed by melting and mixing petroleum wax and oil at a temperature of 100 deg.C. In the coating film protective agent, the petroleum wax and oil are used in a weight ratio of 9:1 in the summer season, while being used in a weight ratio of 1:1 in the winter season.
