Technical Field
The utility model relates to a construction technical field especially relates to a do operation bored concrete pile concrete pipe and connect integrated device thereof.
Background
At present, concrete cast-in-place piles are widely applied to various engineering constructions, pile foundations are mainly divided into mechanical hole forming and manual excavation hole forming according to different hole forming modes, and a common method in the concrete cast-in-place pile casting process is a guide pipe method underwater concrete casting construction technology and a string tube method waterless pile casting, namely a dry operation construction technology. Wherein the former is suitable for filling piles with water and the latter is suitable for filling piles without water or with less water infiltration. By consulting the specification and related technical experience, the smaller water seepage amount means 6 mm/min. In actual construction, underground geological conditions are complex, underground water in pile holes has a plurality of seepage points, and the specific seepage amount is difficult to measure.
The concrete pouring of the common dry operation pore-forming cast-in-place pile generally adopts a tube string method, namely, a concrete hopper is fixed by a bracket at the upper opening of a pile hole, and then workers enter the hole to hang tubes string section by section. The length of each section of string barrel is about 1.0-1.5 m, the number of hanging sections is determined according to the hole depth, and the distance between the bottom opening of the last section of string barrel and the hole bottom is more than 1 m. The concrete transport vehicle moves to the orifice, and starts to feed materials into the hopper, constructors inside and outside the orifice are matched with each other during pouring, blanking is stopped when the concrete surface is controlled to be about 30cm, and workers in the orifice fully vibrate by using an inserted vibrating rod to ensure that each layer of concrete is compact; and then, removing the string cylinders section by section along with the rising of the concrete surface until the concrete is poured to the designed elevation and then over-pouring for 5-10 cm (convenient for chiseling out floating slurry later), and removing the hopper to finish concrete pouring.
The method is characterized in that a concrete pile guide pipe method is adopted according to actual field experience, and the method can also be used for a cast-in-place pile for dry operation hole forming, namely, the pipe diameter of the cast-in-place guide pipe is selected according to the hole diameter of the pile, the guide pipe with the diameter of 400mm is generally adopted for a large-diameter hole pile, the installation and connection are carried out section by section at the hole opening of the pile until the concrete begins to be cast about 1m away from the bottom of the hole pile, the concrete is extracted section by section along with the pouring of the concrete, and the extracted guide pipe. The method generally adopts the separated type of the conduit and the connecting joint, has long butt joint time and low working efficiency, and influences the concrete pouring speed.
