Problems solved by technology

The existing grouting at the bottom of the pile is usually to set the grouting pipe from the bottom of the pile along the steel bar of the pile body, and then directly sleeve the grouting pipe on the grouting pipe for grouting. Due to the connection between the grouting pipe and the grouting pipe Not tight enough, grout leakage is easy to occur during the grouting process, affecting normal construction

Abstract

The invention provides a pile bottom grouting device which comprises a support, a slurry delivery joint pipe and a detachable grouting tool pipe. The slurry delivery joint pipe is arranged on the upper portion of the support, the grouting tool pipe is arranged on the lower portion of the support, the upper end of the grouting tool pipe is communicated with the lower end of the slurry delivery joint pipe, the upper end of the slurry delivery joint pipe is connected with a slurry delivery pipe, and the lower end of the grouting tool pipe is connected with an inner grouting pipe. Construction and grouting can be facilitated for workers, leakage is not easily caused, and normal construction is ensured.

Description

technical field [0001] The invention relates to the construction field, in particular to a pile bottom grouting device. Background technique [0002] Due to the limitation of the construction technology of bored piles, the sediment at the pile tip is not easy to remove, and the soil at the pile tip is easily disturbed, so the bearing capacity of the pile tip is low. Usually, this problem is solved by grouting at the bottom of the pile. The existing grouting at the bottom of the pile is usually to set the grouting pipe from the bottom of the pile along the steel bar of the pile body, and then directly sleeve the grouting pipe on the grouting pipe for grouting. Due to the connection between the grouting pipe and the grouting pipe If it is not tight enough, grout leakage is easy to occur during the grouting process, which will affect the normal construction. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pile bo...
