Concrete pipe pile and pile sinking system thereof and construction method of sea area pile sinking

Abstract

The invention provides a concrete pipe pile and a pile sinking system thereof and a construction method of sea area pile sinking, and belongs to the technical field of pipe pile construction. The concrete pipe pile can sink a pile by a negative pressure suction mode, no damage is caused to concrete during pile sinking construction by the concrete pipe pile, the concrete pipe pile is suitable for construction of a sea area pipe pile, and the construction cost is greatly reduced; the concrete pipe pile comprises a pile body, the inside of the pile body is hollow, the pile body is internally provided with baffles, the baffles divide the pile body into multiple compartments, and openings are formed in the tops and bottoms of the compartments; the pile sinking system comprises the concrete pipepile, an air suction unit and a regulation and control unit; the air suction unit comprises an air suction device and a plurality of air suction pipes connected to the air suction device, and the airsuction pipes are connected to the top openings of the compartments in a sealing mode; and the regulation and control unit comprises pressure sensors and controllers, the pressure sensors are arranged one by one in the compartments, and the controllers are electrically connected with the pressure sensors and the air suction device.

Description

technical field [0001] The invention belongs to the technical field of pipe pile construction, and in particular relates to a concrete pipe pile, a pile sinking system thereof, and a sea area pile sinking construction method. Background technique [0002] In traditional large-scale pipe pile construction, multi-hammer linkage technology is usually used for pile sinking construction, and the soil around the pipe pile is liquefied through resonance, thereby realizing the sinking of the pipe pile foundation. The above multi-hammer linkage pile sinking construction method is more suitable for pipe piles made of materials with better toughness, such as steel pipe piles, etc. For concrete pipe piles, when the multi-hammer linkage pile sinking construction method is adopted, the resonance process is easy to affect the concrete. Impact brittle failure is formed. Therefore, the existing multi-hammer linkage pile sinking construction method is not suitable for concrete pipe piles. Ho...

Problems solved by technology

However, in the construction of pipe piles in sea areas, compared with steel pipe piles, concrete pipe piles have better corrosion resistance and lower cost, but the existing multi-hammer linkage pile sinking construction method limits the concrete pipe pile to a certain extent Application of Pile in Pipe Pile Construction in Sea Area

In addition, in the multi-hammer linkage pile sinking construction method, the weight of the hammer alone is nearly 100 tons, and large-scale lifting equipment is required to assist in the pile sinking process, and a crane ship is required to assist in the construction in sea areas, and the construction cost is extremely high , and its construction noise is large, and it is easy to cause certain pollution to the surrounding environment or sea area
