Waterproof sealing device for pile head of cast-in-place pile

Abstract

The invention relates to a waterproof sealing device for a pile head of a cast-in-place pile, which comprises an upper sealing shaft sleeve and a lower sealing shaft sleeve, a sizing waterproof rubber ring, a horizontal sealing pressure ring and a waterproof roll, wherein the two sealing shaft sleeves have the same shaft and the same diameter, the sizing waterproof rubber ring is arranged betweenthe sealing shaft sleeves in the radial direction, a circle of bulges are made on the sizing waterproof rubber ring in the sealing shaft sleeves; and the connecting part of the sizing waterproof rubber ring and the waterproof roll is pressed and fixedly arranged by adopting the horizontal sealing pressure ring, and the sealing shaft sleeves, the horizontal sealing pressure ring, the waterproof roll and the sizing waterproof rubber ring are connected to form a waterproof whole. The waterproof sealing device has the advantages of simple structure, scientific and reasonable design, reliability in sealing, compact connection of a pile platform and a pile foundation, convenience and rapidness in installation, forms a sealing system around the pile head, effectively solves the problem of water seepage of the pile head, is an optimal waterproof sealing device of the traditional pile head, and has a wide application range.

Description

technical field [0001] The invention belongs to the field of construction and relates to cast-in-place piles, in particular to a pile head waterproof sealing device for cast-in-situ piles. Background technique [0002] After the cast-in-situ pile has completed the pile foundation operation, the upper end of the cast-in-situ pile needs to be waterproofed, so as to avoid water seepage at the pile head and cause water seepage in the basement of the building. At present, the traditional method of waterproofing the pile head is to lay the coiled material directly on the side of the pile head, or to fix the coiled material on the pile head with an aluminum hoop. These two methods have the following problems: [0003] 1. The amount of steel bars in the foundation of the building is generally large, and the rigid waterproof mortar is easily damaged when the steel bars are installed. Because the steel bars are placed, it is not easy to repair after damage; [0004] 2. The combinatio...

Problems solved by technology

[0003] 1. The amount of steel bars in the foundation of the building is generally large, and the rigid waterproof mortar is easily damaged when the steel bars are installed. Because the steel bars are placed, it is not easy to repair after damage;

[0004] 2. The combination of the coiled material and the pile body is not tight, because some pile heads are very irregular in shape, some people use waterproof mortar to treat the pile head, and use aluminum hoops to fix the coiled material on the pile head, but for the pile top If it is a slope, there is nothing you can do. Even if you fix it with an aluminum hoop, you can’t make the coil and the pile head completely tight.
