Description

High-strength prestressed concrete composite pile

Technical Field

The utility model relates to a building pile driver technical field, more specifically say, the utility model relates to a high-strength prestressed concrete composite pile.

Background

Concrete piles are piles made of concrete (including ordinary reinforced concrete, prestressed concrete). The pile has the advantages of saving wood and steel, being durable in use, low in manufacturing cost and the like, is widely used in foundation engineering of hydraulic buildings, industrial buildings, civil buildings and bridges, and is also commonly used for anti-sliding or water-resisting of side slopes and foundation pit supporting, the section of the pile is square, rectangular, circular, annular and the like, and the square section pile and the annular section pile are most commonly used. The side length of the square-section pile and the outer diameter of the annular-section pile are 20-60 cm. The length of the pile can reach 40 meters, the upper end of the pile is provided with a pile cap, and the lower end of the pile is provided with a pile tip. The concrete pile is made by the same process as that of concrete pole, such as drilling (punching or digging) hole to fill pile and prefabricated pile which is drilled and then driven, because the soil in the hole is removed in the setting process, the soil around the pile is not subject to the displacement action and can move into the pile hole, the shearing strength of the soil is reduced, and the side friction resistance of the pile is reduced to a certain extent. Non-extruded soil is generally cast-in-place, and is provided with manual hole digging piles, punching (drilling) hole filling piles and the like. The manual hole digging pile is a reinforced concrete pile which is manually dug and cast in place and has reinforcing steel bars. The manual hole digging pile is generally thicker in diameter, the thinnest is more than 800 millimeters, the manual hole digging pile can bear a structural main body with fewer floors and higher pressure, and the application is common. The pile is provided with bearing platform and connected with bearing platform beam to distribute the stress of the piles homogeneously for supporting the whole building.

The high-strength prestressed square pile and the tubular pile have high strength, but the depth of the pile entering the rock is limited, particularly when a dense sand layer with the depth of more than 3.0m is encountered, the penetration capacity of the square pile and the tubular pile is limited, the bearing capacity of the pile cannot be exerted, the pile length used in the current building construction is too short, the length of the pile below a basement is usually less than 5.0m, some of the pile length is less than 3.0m, the pile length does not meet the basic requirement of the building on the pile length and is not less than 6.0m, in order to penetrate through the sand layer, the problems of pile body damage, vertical cracks, prestressed reinforcement exposure, corrosion and the like are caused, hidden dangers are brought to the building foundation, in order to penetrate through the sand layer, a construction method of firstly leading holes and then pressing the pile is adopted, the sand layer collapses, the pile end is communicated with the sand layer underground water, the mud rock at the pile end is soaked in water for a long time, the mud rock bearing capacity is reduced, and hidden dangers are brought to the durability of the building foundation.
