Description

Multifunctional crawler-type drilling and spraying integrated special grouting machine

Technical Field

The utility model relates to a adopt high-pressure injection grout mode to carry out the grout special mechanical equipment that uses in impervious wall or bearing pile (wall) construction process when underground prevention of seepage reinforcement engineering construction such as water conservancy water and electricity or road bridge, housing construction.

Background

The high pressure jet grouting technology (called high jet for short) is introduced from abroad in the seventies of the last century, and is mainly used for local reinforcement and leakage stoppage of underground engineering in the initial stage. The adopted main process comprises two steps: 1. drilling a hole by using a drilling machine; 2. and (4) using a grouting machine to put a high-pressure spraying device into the formed drill hole, and performing high-pressure spraying grouting operation from bottom to top. As the geological drilling machine is adopted for hole forming, the method is traditional, the equipment popularization rate is high, high-spraying construction can be carried out as long as equipment such as a corresponding high-pressure pump and the like are assembled, and the 'drilling and high-spraying' process continues to the present. The high-pressure spraying technology is firstly tried in railway and metallurgical industries and then is generally applied to seepage-proofing reinforcing projects of dams, dikes and cofferdams of a plurality of domestic rivers and reservoir power stations, and the special technology plays an irreplaceable role in underground seepage-proofing reinforcing projects of water conservancy and hydropower. Over forty years of engineering practice, high-pressure spraying equipment and technology are further developed. At present, the domestic high-spraying technology mainly has the following three forms:

1. drilling and high-speed spraying; although the traditional process has the advantages of light equipment and equipment investment saving, the traditional process has the defects of complex working procedures, low work efficiency, poor quality reliability and the like.

2. Vibrating the hole for high-speed spraying; the technique integrates hole forming and high-pressure jet grouting in a vibration mode, better solves the problem of integration of two techniques of hole drilling and high-pressure jet grouting, integrates a vibrating tube (namely a drill rod) and a high-pressure jet grouting tube and integrates a drill bit and a spray head, and has higher work efficiency and better quality within the range of the hole depth of 5-15 m.

3. Drilling and spraying are integrated; the technology integrates drilling and high spray grouting, adopts a rotary disc type drilling machine or a power head drilling machine to drill holes, and utilizes an integrated high spray pipe to perform high spray grouting in the drilling lifting process.

Most of mechanical equipment adopted by the process can not meet different process requirements of respectively performing fixed spraying, swinging spraying and rotary spraying in the same drilling hole.

In a word, most of the existing drilling and high-pressure spraying equipment utilizes the existing drilling machine to carry out certain modification or splicing, some equipment can only drill holes and can not carry out high-pressure spraying, some equipment can only carry out swinging spraying or can only carry out rotary spraying, most equipment can not respectively and randomly realize fixed spraying, swinging spraying and rotary spraying in the same drill hole, and the real drilling and spraying integration is not realized.
