Abstract
The utility model relates to a hydraulic hammered hollow prefabricated pile, which is the upright concrete cylindrical pile to be with a reinforcing cage building together. The top surface of the pile is covered with a steel plate hoop. The top of the pile is a solid section, the center of which is provided with a slurry injecting pipe. The inner part of a pile body under the top of a solid pile is a cylindrical hollow section. The weight of the pile reduces 25-40% and the distribution reinforcing bar amount reduces 30-50% compared with the solid pile. The utility model can be used on the beating of a hydraulic impact hammer and can bear very large vertical loads. The utility model can be widely used as a basis pile of a groundsill of building engineering, a bearing pole of a building, a supporting protection pile for blocking soil in a basis hole or a pile row type underground continuous wall.
Description
The utility model relates to a kind of construction work foundation member.
In construction work, existing preformed pile generally all is a solid pile, from great, quantity of reinforcement is big, causes construction costs higher, and can not use the hydraulic impact hammer injection.
The purpose of this utility model provides a kind of hydraulic pressure hammering hollow preformed pile, under the prerequisite that guarantees bearing capacity, alleviates deadweight, reduces quantity of reinforcement, reduces construction costs, and the injection of available hydraulic jump bit.
The technical scheme of the utility model hydraulic pressure hammering hollow preformed pile: it be one vertical, build together concrete cylindricality stake with reinforcing cage, it is characterized in that: the end face of stake is surrounded by steel plate hoop, the top of stake is the solid section that there is Grouting Pipe at the center, and the pile body inside under the solid pile top is the cylinder type hollow cross section.
The external cross section of above-mentioned cylindricality stake is square, rectangle or X-shaped.
Above-mentioned stake is long to be 10~100 meters, and wherein solid section is long 0.5~3.5 meter.
The cross sectional area of above-mentioned stake is 250 * 250~800 * 800 (millimeters), and hollow diameter is φ 150~φ 550 (millimeter).
Hydraulic pressure hammering hollow preformed pile of the present utility model can adopt prefabrication or field fabrication, can make also and can make by merogenesis by single-unit, and pile body can adopt reinforced concrete structure or prestressed reinforced concrete structure.Stake end adopts opening section or solid cone shaped cross section, the hollow parts of stake adopts capsule or steel pipe is loosed core or refill in the mold technique construction, can make the straight stake or the taper pile of different cross section and length on demand, concrete piles is C25-C120, uses the hydraulic impact hammer injection.
The utility model has the advantages that: reduce 25-40% than the solid pile deadweight, quantity of reinforcement reduces 30-50%, can bear bigger vertical load, and can not be subjected to underground water and the moist influence that changes, and economic benefit obviously improves.Can be used as load-bearing pillar, the stake of foundation ditch retaining support or the row of piles formula diaphragm wall of the stake of construction work foundation, building.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the 1-1 sectional view of Fig. 1.
Fig. 3 is the 2-2 sectional view of Fig. 1.
As shown in the figure, hydraulic pressure hammering hollow preformed pile be one vertical, build together concrete cylindricality stake with reinforcing cage, the end face of stake is surrounded by steel plate hoop 1, the top of stake is the solid section that there is Grouting Pipe 2 at the center, pile body inside under the solid pile top is cylinder type hollow cross section 3, and the external cross section of cylindricality stake is square, rectangle or X-shaped.Stake is long between 10~100 meters, long 0.5~3.5 meter of solid section.The cross sectional area of stake is between 250 * 250~800 * 800 (millimeters), and hollow diameter is between φ 150~φ 550 (millimeter).
