AI Technical Summary

Technical Problem

During the construction of existing drilling piles, the load-bearing beams are erected above the casing and the casing is easily sinking, and the installation and adjustment of the concrete conduits are not flexible enough, affecting construction safety.

Method used

Design a safety protection device for underwater concrete construction for cast-injected piles. By installing support components and guide cylinders around the cartridge, avoiding pressure on the cartridge, and adjusting the pattern plate and connecting sleeves using lifting cylinders and electrohydraulic jacks or linear motors. The location ensures accurate installation and stability of concrete conduits.

Benefits of technology

It effectively avoids sinking of the guard, improves the installation flexibility and stability of the concrete conduit, ensures construction safety, and can automatically adjust the support force according to the flatness of the ground to maintain the stability of the concrete funnel.

Abstract

The utility model discloses a cast-in-place pile underwater concrete construction safety protection device which comprises a checkered plate, an opening and closing type well mouth and a bearing beam, the opening and closing type well mouth is composed of two symmetrical movable door plates, semicircular holes are formed in the middles of the side edges of the movable door plates, a connecting sleeve is arranged above the opening and closing type well mouth, and a guide cylinder is arranged below the bearing beam. At least three supporting assemblies are arranged below the bearing beam, the supporting assemblies are located on the outer side of the guide cylinder, each supporting assembly comprises a lifting cylinder and a base, and the lifting cylinders are located between the bearing beam and the bases. And the horizontal perpendicularity of the checkered plate and the connecting sleeve can be adjusted through the lifting cylinder, so that it is guaranteed that the position of the concrete guide pipe is accurate after the concrete guide pipe stretches into the pile casing.
