An underground horizontal rapid grouting drilling rig

Abstract

The invention discloses a novel underground horizontal rapid grouting drilling machine. The novel underground horizontal rapid grouting drilling machine comprises an inclined rack frame on a car body; the rack frame is provided with a rotary nozzle; the upper end of the rotary nozzle is connected to a push-pull motor and a rotary power head, and the lower end of the rotary nozzle is arranged on a clamping turning device and a clamping guide device; a guide guniting drilling bit is arranged at the front end of the rotary nozzle, and the tail end of the rotary nozzle is connected to a rotary joint; the rotary joint is connected to an air compressor, a high pressure mud pump, and a high pressure water pump; the guide guniting drilling bit comprises a hollow drilling shaft, a guide plate is arranged at the front end of the hollow drilling shaft, and a material distributing sleeved shaft is arranged at the tail end of the hollow drilling shaft; a palm cover used for covering a guniting hole is arranged on the center of the guide plate; material guiding leaves are arranged on the inner wall of the guniting hole; a guide leaf is arranged on the center of the palm cover; material spraying holes are formed in the material distributing sleeved shaft; an automatic rod changing device is arranged on the side of the rack frame; and the automatic rod changing device comprises a rotary nozzle storage rack and a rod changing movable clamp. The novel underground horizontal rapid grouting drilling machine can improve the structure of the underground soil property without damaging the surface building and the soil, the guniting efficiency is high, and the fastness of improving the solid property is good.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, in particular to an underground horizontal rapid grouting drilling rig. Background technique [0002] Floods occur frequently in southern my country. When houses are soaked by floods, the foundations are soft, which will lead to weak foundations of some houses and easy collapse. At the same time, cracks and cavities will appear in the foundations of mountains or roads after earthquakes, resulting in unstable foundations or mountains. , easy to collapse and natural disasters such as landslides, in order to prevent the occurrence of the above situation, there is a rotary jet drilling machine in the prior art, which can drill holes vertically to the ground, and then spray out mud, concrete, etc. Filling, improving soil quality, and improving underground firmness, but because the rotary grouting drilling machine can only spray and fill vertical holes at the lower end of the car body, its ...

Problems solved by technology

[0002] Floods occur frequently in southern my country. When houses are soaked by floods, the foundations are soft, which will lead to weak foundations of some houses and easy collapse. At the same time, cracks and cavities will appear in the foundations of mountains or roads after earthquakes, resulting in unstable foundations or mountains. , easy to collapse and natural disasters such as landslides, in order to prevent the occurrence of the above situation, there is a rotary jet drilling machine in the prior art, which can vertically drill holes underground, and then spray out mud, concrete, etc. Filling, improving soil quality, and improving underground firmness. However, since the rotary grouting drilling machine can only spray and fill vertical holes at the lower end of the car body, its application field is relatively narrow, especially for mountains, foundations under built houses, and under built roads. Non-destructive filling reconstruction cannot be realized for the foundation, and its shotcrete filling range is narrow, and the filling effect is not ideal
