Abstract

The invention belongs to the technical field of slurry, discloses large-diameter ultra-long punching slurry for a dense pebble bed area, and aims at solving the problem that existing slurry cannot besuitable for the dense pebble bed area. Compared with the existing slurry, the slurry has better dispersity and viscosity and lower water loss; meanwhile, the sand carrying capacity and the stabilityof the slurry can be improved, the slurry is particularly suitable for a complex geological structure of a dense pebble bed, the slurry can quickly form a slurry adhesion layer between the pebbles andthus the pebbles and sand are coated and bonded, hole expansion and hole collapse are reduced, the pebbles are prevented from falling into the hole bottom to a certain extent, the subsequent hole cleaning time is shortened, a good wall protection effect is finally achieved and the hole forming quality is improved.

Description

technical field [0001] The invention belongs to the technical field of cast-in-situ pile construction, and in particular relates to a large-diameter and super-long punching mud in dense pebble layer areas. Background technique [0002] With the improvement of construction level, large-diameter piles have become more and more important forms in bridge engineering due to their advantages such as wide applicability, fast construction speed, and strong bearing capacity. Among all types of pile foundations, cast-in-situ piles are the most common application, and different forms of hole-forming methods are selected according to different geological conditions and engineering needs. At present, the pile length and pile diameter of cast-in-situ piles are continuously increasing, and the requirements for the bearing capacity of single piles are also very high. , the processing difficulty is big, and the cost is also high. [0003] The cast-in-situ pile needs mud to protect the wall...
