A construction method for secondary forming waterproof construction of pile head

Abstract

The invention discloses a construction method for pile head secondary molding waterproof construction, and relates to the technical field of concrete pouring pile pile head waterproof construction; the construction method includes the following steps: pile head breaking-pile head secondary molding tool mold assembly ‑Mold installation‑Pile head overmolding and cushion concrete pouring‑Mould removal‑Installation of expansion waterstops‑Waterproof mortar closure‑Floor waterproofing construction‑Pile head brushing with cement-based permeation crystallization‑Installation of pile head exposed reinforced plastic casing oil Paste potting tool molds, etc. From this, a set of pile head secondary forming tool molds and plastic ointment potting tool molds were designed. Through the implementation of this technical solution, the waterproof cross position between the pile head and the bottom plate can be effectively solved. There is a technical problem of leakage risk, which prevents the leakage risk and hidden dangers of the pile head waterproof construction, reduces the secondary repair cost of the pile head waterproof due to leakage, saves resources, and improves the construction efficiency and efficiency of the pile head secondary forming construction. Pile head waterproof construction quality.

Description

technical field [0001] The invention relates to the technical field of concrete pouring pile head waterproof construction, and more specifically, relates to a construction method for pile head secondary forming waterproof construction. Background technique [0002] With the development of science and technology and the progress of society, construction technology tends to mature level, the state vigorously controls the quality of the construction market, consumers have higher and higher requirements for the quality of construction projects, and their awareness is also getting stronger. Construction quality requirements are more strictly controlled.
