Embodiment Construction

[0016] figure 1 It is a schematic diagram of the overall structure, which is composed of a hollow drill rod and an arc handle on it, a grouting conduit, a movable disc control rod and a reversible helical blade connected to it. The steps to use are:

[0017] 1. Insert 1-4 hollow drill pipes into the ground as needed.

[0018] 2. Press the 1-1 (2-1) movable disc control lever to make the 1-5 reversible helical blade combination open underground.

[0019] 3. Turn on the high-pressure pouring machine, so that the slurry material flows into the 2-6 wedge-shaped blade through the 1-2 (2-4) grouting conduit, and then leaks out from the 4-1 circular continuous small hole.

[0020] 4. Twist the 1-3 arc handle of the 1-4 hollow drill pipe at a uniform speed, so that the 1-5 reversible helical blade combination is driven by the 2-2 bearing rod to follow the 1-4 hollow drill pipe to rotate in the ground, and the slurry The body materials are laid parallel and evenly on the ground.

Abstract

The invention relates to an underground slurry spreading device with an overturning spiral blade combination, which can be used in the engineering field and the agricultural field. The underground slurry paving device with the turnover spiral blade combination comprises a high-pressure pouring device, a hollow drill rod, a fixed three-blade disc, a movable three-blade disc, a movable disc control rod, the turnover spiral blade combination and a slurry injecting guide pipe. The high-pressure grouting device can inject a slurry material into the ground through a grouting guide pipe, the movable three-blade disc moves up and down in the hollow drill rod, and the turnable spiral blade combination can turn over inside and outside through a knife edge on the side wall of the hollow drill rod, so that the contraction and rotation functions of the device are achieved, manual operation is convenient, and carrying is easy. For soft soil, the function of uniformly paving the slurry material under the condition of not disturbing the soil can be realized.

Description

Technical field: [0001] The invention relates to an underground grouting device with an overturned helical blade combination, relates to the fields of geotechnical engineering and agriculture, and is suitable for the construction of underground flat laying slurry on the engineering site or underground fertilization in agricultural engineering, and the like. Background technique: [0002] On the construction site of saline-alkali land improvement or the precise fertilization of the soil of agricultural and forestry land, it is often necessary to apply some slurry materials on the ground under the condition of reducing formation disturbance, similar to slurry fertilizer, mud, etc. The existing construction method is to use large-scale equipment or manpower to excavate and lay the ground soil and then bury it. For example, in the construction of garden scenic spots, the soil layer is often excavated and laid on the ground with fertilizers for plant roots to absorb, and then back...
