Filling pile construction scheme and funnel thereof

Abstract

The invention discloses a filling pile construction scheme and a funnel thereof. The filling pile construction scheme is characterized in that an outlet is formed in the bottom of a funnel body, a sphere which is located in the outlet and adapts to the funnel body is lifted in the funnel body, a lifting rope which is fixed to the sphere is arranged on the sphere, a block is fixed to one end, whichis far from the sphere, of the lifting rope, cross rods are arranged on the top of the funnel body, the cross rods include a fixed rod and a movable rod, a gap which is used for the lifting rope to pass through is formed between the ends of the fixed rod and the movable rod, the width of the gap is less than the block, a vertical guide groove is formed in the funnel body, a floating block is arranged in the guide groove, and a linking mechanism which is used for linking one end, which is close to the fixed rod, of the movable rod to move away when the concrete level in the funnel body reachesthe preset height is arranged on the floating block; concrete is continuously added to the funnel body, the concrete level in the funnel body continuously rises, the floating block continuously movesupwards until the level rises to the preset height, and then the end of the movable rod is linked to move away, so that the block falls off; and at the moment, the sphere and concrete are dischargedfrom the outlet together, and the lifting rope does not need to be manually sheared off, so that the operation is convenient.

Description

technical field [0001] The invention relates to the construction field of cast-in-place piles, in particular to a construction scheme of cast-in-place piles and a funnel thereof. Background technique [0002] Cast-in-situ piles are made by directly opening holes on the designed pile positions with a circular cross-section. After the holes are formed, a reinforcement cage is placed in the holes and concrete is poured. The commonly used method is drilling and pouring. The specific process includes: Site leveling→pile position setting out→excavation of slurry pool and slurry trench→casing burial→drilling rig in place, hole position correction→hole forming, mud circulation, removal of waste slurry and sludge→first hole cleaning→quality acceptance→ Lower the reinforcement cage and steel conduit → clear the hole for the second time → pour underwater concrete → form a pile. During the pouring of concrete, connect a funnel to the steel conduit, pour the concrete into the funnel, and...

[0002] Cast-in-situ piles are made by directly opening holes on the designed pile positions with a circular cross-section. After the holes are formed, a reinforcement cage is placed in the holes and concrete is poured. The commonly used method is drilling and pouring. The specific process includes: Site leveling→pile position setting out→excavation of slurry pool and slurry trench→casing burial→drilling rig in place, hole position correction→hole forming, mud circulation, removal of waste slurry and sludge→first hole cleaning→quality acceptance→ Lower the reinforcement cage and steel conduit → clear the hole for the second time → pour underwater concrete → form a pile. During the pouring of concrete, connect a funnel to the steel conduit, pour the concrete into the funnel, and pour the concrete into the underwater pouring concrete for the first time It is the most important step. This step is directly related to the quality of the whole pile. Generally, a rubber ball or concrete ball suitable for its outlet is hoisted in the funnel in advance, and the hanging rope is cut after the concrete in the funnel reaches the predetermined amount. Make the ball or concrete ball and the concrete leak together, which effectively avoids the segregation of the concrete by the mud erosion, but it needs to be cut manually every time, which is troublesome
