Problems solved by technology

[0003] The technical problem to be solved by the present invention is that in the prior art, the drilling rig with the cutting and eliminating device used to make the thickness of the continuous occlusal pile hole uniform, is easily blocked by the hard object located at the protrusion of the inner wall of the pile hole during the construction process. As a result, the drill pipe cannot be drilled, and this type of drilling rig in the prior art has poor adaptability to different soil environments; thus a method for uniformizing the thickness of continuous occlusal pile holes is proposed, and has a relatively low adaptability to different soil environments.

Embodiment 1

[0033] Such as figure 2 As shown, the wall-forming machine for the continuous cement-soil occlusal pile retaining wall of the foundation pit in this embodiment includes: a power unit 1, which is provided with an air injection port 2 and a water injection port 3; a drill rod mechanism 8, and The power unit is connected, wherein the drill rod mechanism 8 is used to form a plurality of interconnected continuous pile holes at one time, wherein the drill rod mechanism includes a plurality of drill rods, and in this embodiment, the drill rod mechanism The rod is specifically the first drill rod 12, the second drill rod 13 and the third drill rod 14, and the drill bit 8' positioned at the bottom of the drill rod; Air pipe (not marked here), the upper ends of the grouting pipe and the gas injection pipe are connected to the water injection port and the gas injection port respectively, and the lower ends of the grouting pipe and the gas injection pipe are connected to the drill Rod c...

Embodiment 2

[0042] Such as Figure 8 As shown, the difference between the wall-forming machine for the continuous cement-soil occlusal pile retaining wall of the foundation pit of this embodiment is that two drill pipes that are synchronous and rotate in the same direction are provided with at least two The curved section, and the first device is installed on the corresponding curved sections of the two drill rods. The above design can realize that the first device is provided at more than two positions of the drill pipe above and below, which increases the one-time damage width to the protrusion of the soil body, thereby realizing the fast drilling of the drill pipe. It can better destroy the protrusion of the soil. Such as Figure 9 As shown, the curved segments may not bend in the same direction. The above design can realize that the first device is provided at more than two positions of the drill pipe above and below, which increases the one-time damage width to the protrusion of t...

Embodiment 3

[0044] Such as Figure 10 As shown, the difference between the wall-forming machine for the continuous cement-soil occlusal pile retaining wall of the foundation pit of this embodiment compared with the above-mentioned embodiment 1 is that: two drill pipes that are synchronous and rotate in the same direction are provided with a said a curved section, and the first device is jointly installed on the corresponding curved sections of the two drill rods. In addition, the curved section has two curved portions with an inclination angle of 45 degrees and opposite inclination directions. Such as Figure 11 As shown, the drill rod of the wall-forming machine used for the continuous cement-soil occlusal pile retaining wall of the foundation pit can have two above-mentioned curved sections of the present embodiment, as Figure 12 As shown, the drill rod of the wall forming machine used for the continuous cement-soil occlusal pile retaining wall of the foundation pit can have two abov...

Abstract

The invention provides a wall forming machine for a continuous cement-soil interlocking pile retaining wall of a foundation pit. The wall forming machine comprises a power device and a drill rod mechanism. A gas faucet and a water faucet are arranged on the power device. The drill rod mechanism is connected with the power device. The drill rod mechanism is used for forming a plurality of continuous pile holes which are communicated with each other at a time. The drill rod mechanism comprises a plurality of drill rods and drill bits positioned at the lower parts of the drill rods. The drill rods and drill bits are internally provided with grouting pipes and gas injection pipes. The upper ends of the grouting pipes are connected with the water faucet, and the upper ends of the gas injectionpipes are connected with the gas faucet. The lower ends of the grouting pipes and the gas injection pipes are connected with the drill rods. Every two adjacent drill bits are arranged in a staggered manner in the transverse direction and the longitudinal direction in the horizontal direction, and the projection in the vertical direction has overlap parts. Each drill rod at least comprises two straight rod sections which are coaxially arranged and at least one bending section which is positioned in the middle of the two straight rod sections. The wall forming machine further comprises first devices which are installed at the bending sections and are suitable for breaking the soil body parts, protruding towards the inner sides of the holes, on the inner walls of the continuous pile holes.

Description

technical field [0001] The invention discloses a wall forming machine, in particular to a wall forming machine used for retaining walls of continuous cement-soil occlusal piles in foundation pits. Background technique [0002] The retaining wall is used as a soil retaining and / or water-stop structure for the foundation pit, usually formed by the engagement of several piles; for this type of retaining wall, the weakest position of the retaining soil is the position of the engagement of the piles ; In order to obtain a wall with uniform stress strength, Chinese patent document CN100485156C discloses a multi-axis drilling rig, which mainly includes: a support machine, a drilling rig power head and a drilling tool; the support machine is mainly composed of a base that can walk on the ground , consisting of a column on the base, a hoist unit, an operating room and a traction wire rope; the power head of the drilling rig is mainly composed of a movable frame, which is set on the f...
