Description

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

Technical Field

The utility model relates to a bored concrete pile specifically is a bored concrete pile head watertight fittings.

Background

The cast-in-place pile has the advantages of no vibration, no soil squeezing, low noise, suitability for dense urban building areas and the like during construction, and is widely applied to construction. The cast-in-place piles can be classified into cast-in-place piles for dry-work hole forming, cast-in-place piles for slurry retaining wall hole forming, cast-in-place piles for manual hole digging, and the like according to the difference of hole forming processes. The drilling and pouring means that a pile hole is drilled by a drilling machine and concrete is poured into the hole to form a pile. The method is divided into two methods, namely slurry wall protection hole forming and dry operation hole forming, according to whether a drill bit of the drilling machine is constructed in an aquifer of soil. The pipe sinking cast-in-place refers to a pile formed by sinking a steel sleeve with a valve type pile tip or a prefabricated reinforced concrete pile shoe into the soil by a hammering pile-in-place method or a vibration pile-in-place method, and then hammering or vibrating while pulling out a pipe while pouring concrete, wherein the former is called a hammering pipe-sinking cast-in-place pile, and the latter is called a vibration pipe-sinking cast-in-place pile. The pile forming process of the immersed tube cast-in-place pile comprises the following steps: the pile driver is in place → pipe sinking by hammering → loading → pipe pulling while hammering, and concrete is continuously poured → the steel reinforcement cage is put down, concrete is continuously poured and pipe pulling → pile forming is carried out. The manual hole digging indicates that a pile hole is formed by adopting a manual digging method, then a steel reinforcement cage is placed, and concrete is poured to form the pile. In order to ensure the safety of the manual hole digging pile in the construction process, the phenomena of hole wall collapse and sand running must be prevented during construction, reasonable wall protection measures are made, and the construction process flow of the manual hole digging pile is explained by taking the application of wider cast-in-place concrete segmented wall protection as an example. The explosion-expanded cast-in-place pile is characterized in that holes are formed by drilling and explosion expansion, explosives are placed at the bottom of the holes, then a proper amount of concrete is poured in the holes, then the holes are detonated, expanded heads are formed at the bottom of the holes, then a reinforcement cage is placed in the holes, and pile body concrete is poured.

However, the existing pile head waterproof method only treats the pile body with simple waterproof materials, an effective waterproof whole cannot be formed, the pile head and the bottom plate are not uniformly settled or the joint part is not properly treated, and underground water permeates into the bottom plate along the joint part, so that the structural safety and the use function are influenced. Therefore, the waterproof device for the pile head of the cast-in-place pile is provided.
