Description

Technical Field

[0001] This utility model belongs to the field of building foundation pit construction technology, and in particular relates to grouting reinforcement equipment for building foundation pit support pile walls. Background Technology

[0002] In foundation pit construction, grout is injected into the soil to form a unified whole with the piles or walls, thereby improving the soil's strength and stability. However, the long drilling pipe of the grouting equipment results in poor stability during drilling.

Therefore, it is necessary to provide grouting reinforcement equipment for foundation pit support pile walls that can ensure stable advancement, achieve synchronous grouting to effectively prevent foundation pit collapse, and have good guiding and limiting functions to ensure the stability of the grouting drill pipe during drilling.

[0019] In the following description, embodiments of the grouting reinforcement equipment for building foundation pit support pile walls of this utility model will be described with reference to the accompanying drawings.

[0020] Figure 1-4This invention illustrates an embodiment of a grouting reinforcement device for foundation pit support pile walls, comprising a sliding pusher slide 2 slidably connected to the top of a drilling and grouting integrated machine 1; a grouting pipe 3 is disposed above the drilling and grouting integrated machine 1; a cylinder 9 is fixedly installed on the left side of the top of the drilling and grouting integrated machine 1, the output end of the cylinder 9 being fixedly connected to the pusher slide 2; a drilling assembly 12 is disposed on the top of the drilling and grouting integrated machine 1, a rotary joint 10 is fixedly installed on the output end of the drilling assembly 12, the left side of the rotary joint 10 is threadedly connected to the grouting pipe 3; a water injection valve and a grouting valve are welded to the two sides of the top of the rotary joint 10 respectively; a guide sleeve 8 is fixedly installed on the left side of the top of the pusher slide 2, the grouting pipe 3 is slidably connected to the inner cavity of the guide sleeve 8, the guide sleeve 8 provides support for the grouting pipe 3, improving the stability of the grouting pipe 3 and the hollow drill pipe 4 during travel; the left end of the grouting pipe 3 is threadedly connected to the hollow drill pipe 4; and a rotary joint 4 is rotatably connected to the rear side of the top of the pusher slide 2 via a bearing seat. Guide components 6 are provided on both sides of the surface of the moving rod 5 and the rotating rod 5. The guide components 6 include a rotating arm 61 fixedly connected to the surface of the rotating rod 5. A rectangular groove 62 is opened at the top of the rotating arm 61. A clamping arm 63 is rotatably connected to the inner cavity of the rectangular groove 62. An arc-shaped slot 64 is opened on the front side of the bottom of the rotating arm 61. Multiple rotatable balls 11 are embedded in the inner wall of the arc-shaped slot 64 and the clamping arm 63. The surface of the balls 11 rolls in contact with the surface of the grouting pipe 3. Through the setting of the balls 11, the clamping arm 63 and the rotating arm 61 can stably transmit power to the grouting pipe 3 without affecting the rotation and advancement of the grouting pipe 3, thereby improving the stability of the grouting pipe 3 and the hollow drill pipe 4 during the movement. A rotatable electric telescopic rod 65 is installed on the rear side of the rotating arm 61. The output end of the electric telescopic rod 65 is rotatably connected to the rear end of the clamping arm 63. A servo motor 7 is fixedly installed on the left side of the top of the push slide 2. The output shaft of the servo motor 7 is fixedly connected to the rotating rod 5.

[0021] Working Principle: When using this invention, the user moves the integrated drilling and grouting machine 1 to the grouting position, then activates the drilling assembly 12. The drilling assembly 12 drives the grouting pipe 3 to rotate, which in turn drives the hollow drill pipe 4 to rotate. Simultaneously, under the propulsion of the cylinder 9, a hole is drilled into the earthen wall. After drilling to a certain depth, the hollow drill pipe 4 is intermittently pulled outwards. Each time the machine stops, the grouting machine injects grout into the central tube of the grouting pipe 3 and the hollow drill pipe 4 through the grouting pipe, and then sprays grout from the end of the hollow drill pipe 4 into the drilled hole. Grouting can be performed at different depths. An extension pipe is installed between pipe 3 and hollow drill pipe 4. After installation, servo motor 7 is turned on, and servo motor 7 drives rotating rod 5 to rotate. During the rotation of rotating rod 5, rotating arm 61 is driven to rotate, so that arc-shaped slot 64 engages with the surface of extension pipe and grouting pipe 3. Then, electric telescopic rod 65 is opened and pushes clamping arm 63, which in turn rotates around the rotation center at the connection position with rotating arm 61, clamping the surfaces of grouting pipe 3 and extension pipe. During the movement of grouting pipe 3 and extension pipe, ball bearings 11 roll and rotate on the surfaces of the two pipes, so that grouting pipe 3 and extension pipe can operate stably.

[0022] In summary, this grouting reinforcement equipment for foundation pit support pile walls, through the coordinated use of the drilling and grouting integrated machine 1, the propulsion slide 2, and the drilling component 12, propels the grouting pipe 3 and the hollow drill pipe 4 through drilling. With the cooperation of the rotating joint 10, grout is injected into the drilling location. At the same time, with the cooperation of the rotating rod 5, the guide component 6, and the servo motor 7, the travel direction of the grouting pipe 3 and the hollow drill pipe 4 is limited and guided, thus achieving the purpose of stable propulsion and synchronous grouting to prevent collapse.
