Waterproof construction device used for punch filling pile head

Abstract

The invention discloses a waterproof construction device used for a punch filling pile head. The construction device comprises a filling pile body, a cushion layer body, an arc vertical plate and a movable vertical plate. The lower end of the filling pile body penetrates the cushion layer body and extends to the position below the cushion layer body, two water passing expansion water stop strips are wound on the outer side of the upper end of the filling pile body, a first sliding groove is formed in one side of the lower end of the movable vertical plate, one end of fixing block is embedded in the first sliding groove, the other end of the fixing block is fixedly connected with one end of a guide block, the upper side of the other end of the guide block is fixedly connected with one sideof one end of a first clamping plate, the lower side of the other end of the guide block is provided with a second sliding groove, one end of the sliding block is embedded in the second sliding groove, the other end of the sliding block is fixedly connected with one side of one end of a second clamping plate, the water passing expansion water stop strip is arranged, multiple-waterproof operation is carried out on the filling pile body, and the waterproof construction quality of the filling pile body is ensured.

Description

technical field [0001] The invention relates to the technical field related to building construction, in particular to a construction device for waterproofing the head of a perforated cast-in-situ pile. Background technique [0002] The cast-in-place pile is directly drilled on the designed pile position, and its cross-section is circular. After the hole is formed, a steel cage is placed in the hole and concrete is poured. It is used for urban construction, but the cast-in-place pile in the prior art does not have a good waterproof structure, and has the following disadvantages: [0003] 1. At present, the waterproofing of cast-in-place pile heads on the construction site mostly adopts the method of brushing once with waterproof paint, while the soil quality in the pile head area of ​​punched-in-place piles under the geological conditions of reclamation is prone to uneven settlement, and the molding quality is irregular. The waterproof quality of the pile head is not easy t...

AI Technical Summary

Problems solved by technology

It is used for urban construction, but the cast-in-place pile in the prior art does not have a good waterproof structure, and has the following disadvantages:

[0003] 1. At present, the waterproofing of cast-in-place pile heads on the construction site mostly adopts the method of brushing once with waterproof paint, while the soil quality in the pile head area of ​​punched-in-place piles under the geological conditions of reclamation is prone to uneven settlement, and the molding quality is irregular. The waterproof quality of the pile head is not easy to guarantee;

[0004] 2. The existing waterproof construction of cast-in-situ piles is all completed by workers. This method is time-consuming and laborious, which greatly reduces the construction progress
