[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Among the construction methods of urban subway station enclosure structures, the CSM cement soil mixing wall support method is currently commonly used. This construction process uses a double-wheel mixing drill to rotate and mix, cutting the original soil around the station foundation pit. During this process, cement slurry and gas are injected to change the mechanical properties of the original soil and form an underground continuous wall of cement soil with equal thickness. The advantages of this technology are fast construction speed, strong stratum adaptability, good water-stopping curtain effect, low noise and vibration, and little impact on surrounding urban buildings and residential environment.

[0004] Due to the large length and span of the subway station, the CSM cement-soil mixing wall needs to be carried out in sections. During the rotation and mixing process of the double-wheel mixing drill, the travel route needs to be strictly controlled. The traditional method requires marking the boundary line of the retaining structure on the ground, hanging a plumb bob on the double-wheel mixing drill, and guiding the movement of the double-wheel mixing drill by observing the vertical overlap relationship between the plumb bob and the boundary line. This method requires the cooperation of on-site technicians and machine operators, is backward, and occupies manpower.

[0005] On the other hand, when the double-wheel mixing drill rotates and mixes the original soil, the mixed mud of the original soil, cement slurry and gas is easy to splash out, polluting the roads around the foundation pit, and affecting the walking workers and running machinery and vehicles, posing a safety hazard.

DETAILED DESCRIPTION

[0024] It should be noted that the following detailed descriptions are all exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0025] The utility model is described in detail below in conjunction with the accompanying drawings. The embodiment disclosed herein is a walking positioning and mud protection device for a double-wheeled mixing drilling rig. Figure 1As shown, it includes three parts: a retaining wall system 2, a laser emitter 3, and a high-pressure air blower 4.

[0026] As Figure 1 and Figure 2 shown, the retaining wall system 2 includes a top plate 21 with a rectangular hollow structure. When the top plate 21 is placed horizontally, there is a large opening in the middle. The top view of the top plate 21 is a rectangular plate in the shape of a Chinese character 'hui'. As Figure 2 shown, the top plate 21 is divided into four plates, including a first plate 211, a second plate 212, and two third plates 213. It can be understood that both ends of the first plate 211 are perpendicularly and fixedly connected to the two third plates 213, and both ends of the second plate 212 are perpendicularly and fixedly connected to the two third plates 213; the first plate 211 and the second plate 212 have the same length, but the area of the second plate 212 is larger than that of the first plate 211. The first plate 211 and the second plate 212 are parallel to form the long side of the top plate 21; the two third plates 213 have the same length and the same area, forming the wide side of the top plate 21.

[0027] The large opening in the middle of the top plate 21 with a rectangular hollow structure is for the double-wheel mixing drill 1 to pass through. The top plate 21 of the retaining wall system 2 is connected to the double-wheel mixing drill 1 by existing welding technology or anchoring technology (not shown in the figure). The top plate 21 of the retaining wall system 2 is perpendicular to the double-wheel mixing drill 1. Since the double-wheel mixing drill 1 works perpendicular to the ground, the top plate 21 of the retaining wall system 2 is in a horizontal state. The second plate 212 is located on one side of the double wheels of the double-wheel mixing drill 1.

[0028] As Figure 2 shown, a number of first holes 2121 are opened on the second plate 212. The number of first holes 2121 is evenly spaced in the length direction of the second plate 212. At two corner points on the side of the second plate 212 far from the double-wheel mixing drill 1, two second holes 2122 are also opened.

[0029] As Figure 2 shown, the retaining wall system 2 further includes a circular spirit level 22, a retaining wall 23, and a retaining wall angle steel 24. Among them, the circular spirit level 22 is installed at the corner position of the first plate 211. By adjusting the bubble in the spirit level to be centered, the horizontal state of the top plate 21 of the retaining wall system can be determined. Then, the top plate 21 of the retaining wall system is connected to the vertically placed double-wheel mixing drill 1 by welding or anchoring to achieve the fixing function of the entire device.

[0030] As Figure 2As shown, the bottom surface of the guard wall 23 is vertically welded to the second plate 212. In order to prevent deformation of the guard wall 23, guard wall triangle steels 24 are welded at both ends of the guard wall 23. The top end of the guard wall triangle steel 24 is connected to the bottom of the second plate 212, and the bottom end of the guard wall triangle steel 24 is connected to the bottom of the guard wall 23. The length between the guard wall triangle steels 24 cannot exceed the length between the inner edges of the second hole 2122.

[0031] like Figure 1 and Figure 2 As shown, the laser emitter 3 is fixedly connected to the second hole 2122. Figure 3 As shown, the laser emitter 3 includes a cylindrical laser emitter body 31 and a hemispherical laser emitter head 32; the laser emitter body 31 and the laser emitter head 32 are consistent with the diameter of the second hole 2122, and one end of the laser emitter body 31 is welded and fixed to the second hole 2122. The laser emitter head 32 is fixedly connected to the other end of the laser emitter body 31. The laser emitter body 31 is perpendicular to the second plate 212, and the laser beam emitted by the laser emitter 3 is perpendicular to the second plate 212.

[0032] The laser beam emitted by the connected laser transmitter 3 is perpendicular to the second plate 212, and the laser beam emitted by the laser transmitter head 32 is vertically irradiated on the boundary line of the retaining structure that has been laid out on the ground; when the double-wheel mixing drill is working, since the double-wheel mixing drill is perpendicular to the ground and the top plate respectively, and the laser beam is perpendicular to the top plate, the laser beam is always parallel to the double-wheel mixing drill. When the double-wheel mixing drill is moving, the staff controls the laser beam to always illuminate the boundary line of the retaining structure that has been laid out on the ground, so as to accurately control the walking route of the double-wheel mixing drill 1.

[0033] like Figure 1 and Figure 2 As shown, a plurality of high pressure air outlets 4 are installed on the first holes 2121 of the second plate 212. Figure 4 As shown, the high-pressure air outlet 4 includes a high-pressure air outlet connecting pipe 41 and a high-pressure air outlet outlet 42 , and the diameter of the cylindrical high-pressure air outlet connecting pipe 41 is consistent with the diameter of the first hole 2121 .

[0034] A flat opening is opened in the middle of the bottom end of the high-pressure air outlet connecting pipe 41, which is fixedly connected to the flat high-pressure air outlet 42. The high-pressure air outlet 4 is close to the protective wall 23, and the top opening of the high-pressure air outlet connecting pipe 41 is connected to an external high-pressure blower (not shown in the figure), and the high-pressure air outlet connecting pipe 41 is perpendicular to the second plate 212.

[0035] The high-pressure air outlet 4 is connected to an external high-pressure blower, and blows out high-pressure air through the air outlet 42 of the high-pressure air outlet to clean the mud splashed on the inner side of the protective wall 23, thereby maintaining the cleanliness of the protective wall 23, so that the protective wall 23 can keep working for a long time while protecting the mud.

[0036] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
