Construction method for pile head secondary forming waterproof construction

Abstract

The invention discloses a construction method for pile head secondary forming waterproof construction, and relates to the technical field of waterproof construction of a cast-in-place concrete pile head. The construction method comprises the steps of breaking a pile head; assembling a pile head secondary forming tool type mold; arranging the mold; carrying out pile head secondary forming and cushion layer concrete pouring; dismantling the mold; arranging expansion water stop strips; sealing waterproof mortar; carrying out bottom plate waterproof construction; brushing cement-based capillary crystallization on to the pile head; and arranging pile head exposed steel bars and a plastic sleeve factice crack pouring tool type mold and the like. One pile head secondary forming tool type mold andthe plastic factice crack pouring tool type mold are designed in a targeted mode, through the implantation of the technical scheme, the technical problem that the leakage risk exists at waterproof cross positions between the pile head and a bottom plate can be effectively solved, so that the leakage risk and hidden danger existing in pile head waterproof construction are prevented, the secondaryrepairing cost caused by leakage of the waterproof pile head is reduced, resources are saved, and the secondary forming construction efficiency of the pile head and the waterproof construction qualityof the pile head are improved.

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.
