Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a high-pressure jet grouting pile water-stop curtain construction device. Background Technology

[0002] In the field of building construction, especially in underground engineering, the construction of water-stop curtains is crucial. High-pressure jet grouting piles are a commonly used method for water-stop curtain construction. By injecting cement grout and other materials under high pressure, the soil and grout are mixed and solidified to form a pile with a certain strength and impermeability, thereby achieving the purpose of water stoppage. However, during jet grouting, the jet grouting pipe may sway and shake due to the large jetting force, which is not conducive to the accuracy of jet grouting.

[0003] Chinese patent application number CN202220481388.1 discloses a high-pressure jet grouting pile water-stop curtain construction device. This device includes a base, a cement slurry mixing tank, and a second cement slurry connecting pipe. The cement slurry mixing tank and the feeding pump are mounted on the base, and the lower part of the base is equipped with movable rollers. The base and the movable rollers constitute a moving device, which facilitates the adjustment of the position of the cement slurry mixing tank, the feeding pump, and the jet grouting pipe, effectively reducing the possibility of blockage in the cement slurry connecting pipe. However, during jet grouting, the jet grouting pipe in the high-pressure jet grouting pile water-stop curtain construction device mentioned in the above patent may shake and sway due to the large jetting force, affecting the jet grouting effect.

[0031] The clamping assembly 1 includes a housing 101. A limiting ring 102 is fixedly connected inside the housing 101. A bearing 103 is rotatably connected inside the limiting ring 102. The bottom end of the bearing 103 passes through the bottom end of the limiting ring 102 and is fixedly connected to a first worm gear 104. A first motor 105 is fixedly connected inside the housing 101. A first worm 106 is fixedly connected to the transmission end of the first motor 105.

The top end of the bearing 103 passes through the top end of the limiting ring 102 and is fixedly connected to a rotating ring 109. An arc-shaped groove is formed at the upper end of the rotating ring 109. A positioning ring 107 is disposed inside the outer casing 101 and above the rotating ring 109. Multiple equidistant fixing posts 108 are fixedly connected to the outer wall of the positioning ring 107. The fixing posts 108 are fixedly connected to the outer casing 101. Multiple equidistant sliders 110 are slidably connected to the top of the positioning ring 107. Clamping plates 111 are fixedly connected to the inner ends of the sliders 110. The clamping plates 111 are adapted to the limiting ring 102, bearing 103, first worm gear 104, positioning ring 107, and rotating ring 109. A sliding rod is fixedly connected to the bottom end of the slider 110. The sliding rod extends through the bottom end of the positioning ring 107 into the interior of the arc-shaped sliding groove, and the arc-shaped sliding groove is slidably connected to the sliding rod.

[0032] The first motor 105 drives the first worm gear 106 to mesh with the first worm wheel 104, which in turn drives the bearing 103 and the rotating ring 109 to rotate. Then, through the cooperation of the slide rod and the arc-shaped slide groove, the slider 110 and the clamping plate 111 can be adjusted to a certain position to adapt to different sizes or working conditions, so as to achieve precise clamping and adjustable effects.

[0033] The support assembly 2 includes multiple equally spaced support legs 201, with brake casters 202 rotatably connected to the bottom ends of the support legs 201. By setting multiple equally spaced support legs 201 and rotatably connecting brake casters 202 to the bottom ends of the support legs 201, the entire construction device becomes mobile, facilitating movement to different construction locations and improving the flexibility and convenience of construction.

[0034] A connecting arm 203 is fixedly connected to the top of the outrigger 201. A sliding sleeve 204 is fixedly connected to the end of the connecting arm 203 away from the outrigger 201. The sliding sleeve 204 is located above the clamping assembly 1 and is fitted onto the outside of the spray assembly 4. Through the connecting arm 203 at the top of the outrigger 201 and the sliding sleeve 204 at one end of the connecting arm 203, and with the sliding sleeve 204 fitted onto the outside of the spray assembly 4, the supporting assembly 2 provides support and positioning for the spray assembly 4, making the spray assembly 4 more stable during operation and ensuring its normal operation and the accuracy of water spraying.

[0035] The rotary jet assembly 4 includes a nozzle 401, which is adapted to the sliding sleeve 204 and the clamping plate 111. By setting the nozzle 401 and adapting it to the sliding sleeve 204 and the clamping plate 111, the nozzle 401 can be stably clamped and positioned in the device, ensuring that it will not shake or shift during high-pressure rotary jet operation, thus ensuring the stability and accuracy of water spraying.

[0036] The outer wall of the nozzle 401 is provided with toothed grooves. By providing toothed grooves on the outer wall of the nozzle 401, a basis is provided for cooperation with other components. This facilitates the adjustment of the position of the nozzle 401 or driving it to perform specific movements through gear transmission or other means, thereby achieving more precise construction operations.

By rotatably connecting the connector 402 to the top of the nozzle 401 and fixing a pair of symmetrical connecting pipes 403 to the middle of the connector 402, materials are input into the connecting pipes 403 and transported to the nozzle 401 through the connector 402. The nozzle 401 sprays the materials out through a high-pressure rotary spray method, thereby improving the construction of the waterstop curtain.

[0038] The adjustment assembly 3 includes a fixed arm 301 fixedly installed at the top of the right support leg 201. A protective shell 302 is fixedly connected to the end of the fixed arm 301 away from the support leg 201. A second motor 303 is fixedly connected to the outer wall of the protective shell 302. A second worm gear 304 is fixedly connected to the transmission end of the second motor 303. The end of the second worm gear 304 away from the second motor 303 extends through the outer wall of the protective shell 302 and into its interior. By fixing the fixed arm 301 at the top of the right support leg 201, fixing the protective shell 302 to one end of the fixed arm 301, fixing the second motor 303 to the outer wall of the protective shell 302, and connecting the transmission end of the second motor 303 to the second worm gear 304, the adjustment assembly 3 is provided with a power and transmission foundation. The second motor 303 can drive the second worm gear 304 to rotate, providing a power source for subsequent adjustment of the position or movement of components such as the nozzle 401, thus realizing the adjustment function of the construction device.

[0039] A rotating shaft 305 is rotatably connected inside the protective shell 302. A second worm gear 306 is fitted in the middle of the rotating shaft 305 and is fixedly connected to the rotating shaft 305. A gear is fitted at one end of the second worm gear 306 and outside the rotating shaft 305. The gear is fixedly connected to the rotating shaft 305 and is adapted to a tooth groove. The second worm gear 306 drives the gear to rotate. The engagement of the gear and the tooth groove allows the second worm 304 to drive the second worm gear 306 to rotate, thereby moving the nozzle 401 up and down to adjust its height to meet different construction needs.

[0040] Specific implementation process: First, move the construction device to the pile hole at the construction site, positioning the jet grouting assembly 4 directly opposite the center of the pile hole. Start the first motor 105. The transmission end of the first motor 105 drives the first worm gear 106 to rotate. Since the first worm gear 106 meshes with the first worm wheel 104, the first worm wheel 104 rotates accordingly, thereby driving the bearing 103, which is fixedly connected to the first worm wheel 104, to rotate. The bearing 103, in turn, drives the rotating ring 109, which is fixedly connected to its top, to rotate. When the rotating ring 109 rotates, its upper arc-shaped groove cooperates with the bottom sliding rod of the slider 110, causing the slider 110 to slide at the top of the positioning ring 107, thereby driving the slider... The clamping plate 111, fixedly connected to the inner end of 110, is adjusted to a position. Based on the dimensions of the nozzle 401 to be installed, the clamping plate 111 precisely clamps and fixes the nozzle 401, ensuring its stability within the device and facilitating rotary spraying. At this time, the nozzle 401 is fitted inside the sliding sleeve 204. The support legs 201, connecting arm 203, and sliding sleeve 204 of the support assembly 2 jointly provide stable support for the nozzle 401. Then, when the height of the nozzle 401 needs to be adjusted according to construction requirements, the clamping plate 111 is first released from the nozzle 401, and the second motor 303 in the adjustment assembly 3 is started. The transmission end of the second motor 303 drives the... The second worm gear 304 rotates, driving the second worm wheel 306, which is fixedly connected to the rotating shaft 305 inside the protective shell 302, to rotate. The second worm wheel 306 drives the gear to rotate through the rotating shaft. Because the gear is compatible with the tooth groove on the outer wall of the nozzle 401, the rotation of the gear will drive the nozzle 401 to move up and down. When the position of the nozzle 401 needs to be adjusted, the clamping assembly 1 first releases the nozzle 401 to adjust it. The adjusting assembly 3 then drives the nozzle 401 to move up and down to adjust its height so as to meet the specific spraying requirements of the waterstop curtain construction. Finally, after the height of the nozzle 401 is adjusted, the clamping plate 111 is used again to adjust the nozzle 401. The device is clamped, and then high-pressure slurry or other construction materials are delivered into the nozzle 401 through the connector 402 and sprayed out through the rotating nozzle at the bottom of the nozzle 401 to form a water-stop curtain at the construction position. During the construction process, the first motor 105 and the second motor 303 can be finely adjusted again according to the actual situation to ensure that the nozzle 401 is at a suitable height, so as to ensure the stability of the nozzle 401 and the accuracy of the spraying effect of the rotating nozzle. After the construction is completed, the first motor 105 and the second motor 303 are turned off, the clamp 111 is released, the nozzle 401 is taken out of the device, and then the device is moved to the next construction position. The above operation is repeated to construct the next water-stop curtain.
