A recyclable grouting reinforcement equipment for bridge pile foundation

Abstract

The application discloses a recyclable grouting reinforcement equipment for a bridge pile foundation, and relates to the technical field of pile foundation reinforcement. The equipment comprises a leakage prevention mechanism, which is arranged between a concrete cylinder and a solid prevention pipe mechanism. The leakage prevention mechanism is used for solidifying slurry close to the leakage prevention mechanism in a heating mode, and the solidified concrete seals the connection position of the concrete cylinder. The leakage prevention mechanism comprises a blocking assembly. The solid prevention pipe mechanism delivers concrete slurry to the inside of the concrete cylinder. The concrete gradually fills the inside of the concrete cylinder. When the inside of the concrete cylinder is filled with the slurry, an outer threaded cylinder compacts the concrete. Hot oil is introduced into the inside of a quick heating assembly to promote the solidification of the upper layer of concrete. The concrete close to the quick heating assembly forms a dense barrier for the concrete below. The problem that the penetration pressure of slurry to the soil layer at the pile end is insufficient due to the upward leakage of grouting liquid is solved.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pile foundation reinforcement, in particular to a recyclable grouting reinforcement equipment for bridge pile foundation. BACKGROUND

[0002] The bridge pile foundation penetrates the slurry into the soil around the loose pile end tip, and combines to form high-strength concrete. With the increase of grouting amount, the cement slurry continuously penetrates into the pile end bearing layer which is soft due to immersion in the slurry, increasing the bearing capacity of the pile end. When the penetration capacity of the cement slurry is limited by the surrounding dense soil layer, the pressure is continuously increased, and the pile end soil layer is extruded, densified, filled, consolidated, and penetrated, effectively reinforcing or compacting the disturbed bearing layer at the pile bottom and the pile end, improving the connection between the pile and the soil, and improving the bearing capacity of the soil around the pile, thereby improving the single pile bearing capacity and the settlement and uneven settlement of the foundation. Recirculating grouting refers to the continuous circulation of slurry, which requires a larger pump displacement than the rock slurry absorption. The slurry entering the hole section is partially diffused into the cracks, and the remaining slurry returns to the ground and can be reused. The slurry in all grouting sections is always in a circulating flow state. With the extension of the grouting time and the decrease of the slurry absorption, the flow rate of the slurry will be larger and larger, which can reduce the sedimentation of cement particles in the hole section and is not prone to "pipe solidification" accidents, which is beneficial to improve the grouting quality and efficiency.
