Problems solved by technology

However, due to the complex environment in urban construction, for example, when constructing in height-limited areas such as under viaducts, or in areas with narrow boundaries, there may not be an appropriate place to park the drilling mixer, so construction cannot be carried out.

Embodiment Construction

[0028] The present invention will be further described in detail through the accompanying drawings and specific embodiments below.

[0029] Such as Image 6 As shown, a guide device for SMW pile construction according to the present invention includes a support mechanism 11 capable of supporting a drill pipe, an angle adjustment mechanism 12 and a moving mechanism 13 .

[0030] The support mechanism 11 is provided with a guide part 110. In this embodiment, the support mechanism 11 is cylindrical, so that the guide part 110 is a through hole, and the drill rod can pass through the guide part 110 and along the guide part 110. The guide part 110 moves, and the extension direction of the guide part 110 has an included angle with the vertical direction, which is the angle at which the drill pipe enters the foundation when drilling, and the included angle can be set according to the actual construction situation.

[0031] The support mechanism 11 is installed on the angle adjustmen...

Abstract

The invention discloses a guiding device for SMW construction method pile construction. The guiding device comprises at least one supporting mechanism capable of supporting drill rods, guiding parts are arranged on the supporting mechanisms, the guiding parts are straight flutes or through holes, the drill rods can penetrate through the guiding parts and can move along the guiding parts, and included angles are arranged between the extension directions and the vertical directions of the guiding parts. The invention further discloses SMW construction method pile construction equipment. The SMWconstruction method pile construction equipment comprises a drilling and tunneling stirring device and the guiding device. The invention further discloses a SMW construction method pile construction method. The SMW construction method pile construction method is realized through the SMW construction method pile construction equipment. By adopting the technical scheme, angles of the drill rods canbe obliquely arranged, so that the drill rods are obliquely drilled into a foundation to be conveniently constructed under viaducts, in narrow areas or in other complex environments, application ranges of a SMW construction method are increased, and the problems that the construction is difficult and cannot be carried out under the conditions are effectively solved.

Description

technical field [0001] The invention relates to a guide device for SMW pile construction, SMW pile construction equipment and a construction method, and belongs to the technical field of construction equipment and methods. Background technique [0002] The SMW construction method is also known as the new cement-soil mixing pile wall, that is, inserting H-shaped steel (mostly H-shaped steel, but also Larsen type steel sheet piles, steel pipes, etc.) , making it a retaining wall of a supporting structure with both functions of force bearing and anti-seepage. In the construction of SMW method, a single-axis or multi-axis drilling mixer is used to drill to a certain depth on site. The drilling mixer includes a drill bit assembly and a lifting assembly for lifting the drill bit. The power head and the sprinkler irrigation device spray out the cement-based strengthening agent through the sprinkler irrigation device during drilling and excavation to repeatedly mix and stir with th...
