Abstract

A drilling and grouting tool which integrates the drilling and the grouting has a drive drill rod, a short drill rod (1) and a connector (2), wherein the upper end of the short drill rod is connected with the drive drill rod and a driller, and the lower end is connected with a guide tube (3) through the connector, the lower end of the guide tube is connected with a full-face drill head (4), and a swing-up type aperture sealer is connected on an aperture tube on the ground. The drilling and grouting technology comprises the steps that firstly tripped into the drilling and grouting tool, driving the drilling head to crack rocks with the axial pressure and the radial torque force of the driller through the drive drill rod, the short drill rod and the guide tube, moving the drilling and grouting tool a certain distance from the bottom of the hole, cleaning the drill hole with pure water which has certain pressure and is provided by a water pump, and finally moving the drilling and grouting tool a certain distance from the bottom of the hole, connecting the swing-up type aperture sealer with the aperture tube, then rotating with a gland (5), compressing and expanding with a sealing ring (8) to contact with a grouting tube, namely the drive drill rod, thereby realizing the enclosure of the aperture. Slurry can be grouted into the grouting sections according to the different grouting designs, and the circulating slurry in the aperture can be returned from a recycle slurry pipe (7).

Description

Technical field: [0001] The invention belongs to the technical field of basic treatment, and in particular relates to a drilling and irrigation integrated drilling and irrigation equipment and technology. Background technique: [0002] Grouting technology is one of the most important technologies in foundation treatment. It has a history of nearly 200 years and is now widely used in various foundation treatments and engineering protection. [0003] In the current grouting project, the depth of the grouting hole is generally <100m, and a few are 100-160m. The length of the grouting section is generally designed to be 5m. Grouting" three processes. The drilling process of the grouting section requires multiple drilling times, and each drilling time needs to lower the drilling tool, drill, salvage the core, and lift the drilling tool, and complete a grouting section drilling again and again; the grouting section flushing process, After the drilling of the grouting section ...
