Single-slurry blending device for hole drilling and sealing

Abstract

The invention relates to a single-slurry blending device for hole drilling and sealing. The device is composed of a feeding tank, a mixing pipe, a motor, a spiral pushing paddle and a water inlet pipe. The water inlet pipe is sequentially divided into a first mixing section and a second mixing section in the feeding direction, at least two single-slurry nozzles are arranged in the first mixing section in the axial direction, a mixing cavity is formed in the rear sides of the single-slurry nozzles, the spiral pushing paddle is installed in the mixing cavity, and the motor is used for driving the spiral pushing paddle. The mixing pipe is provided with a return plate in front of each single-slurry nozzle, and the return plates are used for rebounding the single slurry sprayed by the single-slurry nozzles to the outer walls of the single-slurry nozzles to form rotational flow. The second mixing section is sequentially provided with at least two groups of inclined plates and baffles, the inclined plates are arranged at the lower part, and the baffles are arranged at the upper part, so that single slurry impacts the baffles along the inclined plates, then flows down and is finally fed into a grouting device through a discharge hole of the mixing pipe, the direct mixing configuration in the feeding process is completed, and the construction flow is saved.

Description

technical field [0001] The invention relates to the field of single-liquid slurry for drilling and sealing, in particular to a single-liquid slurry preparation device for drilling and sealing. Background technique [0002] Single-fluid grouting defines grouting that uses one grout and one grout delivery system. Its working principle is: the portable grouting pump is mainly used in mines, tunnels, water conservancy, subways, buildings, bridge construction, for grouting water blocking, filling gaps, grouting consolidation of broken rock formations, anchor cable grouting; It is used to repair local defects such as muddying of roadbeds and railways, as well as soft ground treatment; to eliminate underground hidden dangers in flood fighting and emergency rescue. For example, during the blasting construction process, it is necessary to drill holes to bury explosives. After the blasting drilling and core drilling are completed, each hole needs to be sealed. It can be deployed acc...

Problems solved by technology

[0003] In the prior art, the preparation of single liquid slurry is generally made by using equipment such as concrete mixers or mixing tanks according to the prefabricated mixture ratio, and then transported to the construction site by tank truck. The disadvantage of this method is that there must be enough stock, and the transportation must be timely, otherwise there will be insufficient materials. At the same time, if there are too many ingredients, they cannot be stored for a long time, which will cause material waste and increase the construction cost.
