Construction method for quicksand layer pile foundation
The invention discloses a construction method for a quicksand layer pile foundation. The construction method comprises the following steps that S10 the depth of a quicksand layer around the pile portion is surveyed, the length of the quicksand layer capable of penetrating through a steel pile casing is determined according to the survey result, and the steel pile casing is prefabricated; S20 the whole steel pile casing is embedded in the pile portion with the adoption of a vibratory hammer; S30 a pore is drilled and formed in the steel pile casing, a reinforcement cage is installed in a pore after the pore is formed, and the reinforcement cage is positioned on the pore opening after the reinforcement cage is installed; and S40 a conduit is installed and fixed in the pore, concrete is injected into the pore through the conduit after the pore is cleaned up, the steel pile casing is lifted immediately after the concrete is injected to the top face of the steel pile casing, the lifting time of the steel pile casing is controlled in the initial set time of the concrete, and the concrete sets and forms the pile foundation after the steel pile casing is lifted out totally. According to the construction method for the quicksand layer pile foundation, the quicksand layer pile pore can be prevented from collapsing effectively, and sand layer loss and the exceeding square amount of the concrete in the pore are controlled well, so that the use amount of the concrete is reduced, mud treatment and discharging are decreased, the mud is prevented from polluting the environment, the construction cost is reduced, the construction period is short, and the benefit is high.
