Description

Technical Field

[0001] The present invention relates to the technical field of underground continuous wall construction, in particular to a water-rich sand layer underground continuous wall construction device and a construction method thereof. Background Art

[0002] In underground engineering construction, underground continuous wall is a commonly used retaining and water-intercepting structure. Its construction quality plays a key role in the stability and waterproof performance of the entire project. Among them, the joint treatment between adjacent trench continuous walls is an important link in the construction process. The cleanliness of the joints of the underground continuous wall lock pipe directly affects the connection tightness and waterproof effect between the walls. If the floating slurry impurities in the joints are not cleaned, it will bring leakage risks to subsequent projects.

[0003] Traditional cleaning of underground continuous wall lock pipe joints mostly adopts the design of simply installing a wire brush on one side of the rectangular frame. During construction, the entire device is mainly lifted by a crane, so that the wire brush is close to the wall to be brushed for cleaning operations. However, during the wall brushing process, this traditional device is in a suspended state during the lifting operation and lacks effective positioning and limiting measures. As a result, the wire brush cannot stably and tightly fit the joint surface of the underground continuous wall during the wall brushing process. This makes it difficult to thoroughly clean the slurry and impurities at the joint, and the cleaning effect is greatly reduced. Not only that, incomplete cleaning will seriously affect the connection quality between the continuous walls and increase the risk of wall leakage. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides a water-rich sand layer underground continuous wall construction equipment and a construction method thereof, which solves the problem of poor cleaning effect at the locking pipe joints of the traditional underground continuous wall.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a water-rich sand layer underground continuous wall construction equipment, including a hoisting frame arranged between two adjacent slot sections of continuous walls, the bottom end of the hoisting frame is fixedly connected to a telescopic cylinder, both sides of the interior of the telescopic cylinder are slidably connected to telescopic rods, the ends of the two telescopic rods are fixedly connected to a cleaning box, the bottom of the inner cavity of the cleaning box is rotatably connected to a rocker through a rotating member, the rocker passes through the cleaning box and extends to the outside of the cleaning box, the end of the rocker extending to the outside of the cleaning box is fixedly connected to a wire brush, one side of the inner cavity of the cleaning box is fixedly connected to a drive motor, and the output end of the drive motor is fixedly connected to the rotating rod through a coupling. The top end of the lifting link is connected with the lifting link of the lifting link, and the lifting link is connected with the lifting link of the lifting link through the rotation of the lifting link.

[0006] Preferably, the top of the inner cavity of the cleaning box is rotatably connected to a conduit through a rotating part, the surface of the conduit is connected to a water supply pipe, one end of the water supply pipe passes through the cleaning box and extends to the top of the cleaning box, one end of the conduit passes through the cleaning box and extends to the outside of the cleaning box, the end of the conduit extending to the outside of the cleaning box is connected to a water supply pipe, and the side of the water supply pipe is connected to several high-pressure nozzles.

[0007] Preferably, a sleeve is fixedly connected to the rear side of the inner cavity of the cleaning box, a cross bar is slidably connected to the inside of the sleeve, the end of the cross bar is fixedly connected to a resistance frame used in conjunction with the eccentric wheel, and the top of the cross bar is fixedly connected to a U-shaped frame used in conjunction with the catheter through a connecting rod.

[0008] Preferably, the bottom of the cleaning box is fixedly connected to the second slide cylinder by a connecting rod, a stabilizing rod is slidably connected in the second slide cylinder, a roller is provided at one end of the stabilizing rod, and a vertical plate is fixedly connected to the other end of the stabilizing rod, the top of the vertical plate is fixedly connected to the bottom of the cleaning box, and a spring is provided on the outer periphery of the stabilizing rod and between the second slide cylinder and the vertical plate.

[0009] Preferably, the telescopic cylinder is provided with a threaded through hole for threaded connection with a screw rod, and the surface of the telescopic rod is provided with a plurality of thread grooves for use with the screw rod.

[0010] The present invention also discloses a construction method of an underground continuous wall of a water-rich sand layer, which specifically comprises the following steps: S1. Slide the telescopic rod according to the width of the underground continuous wall of the two adjacent slot sections. The two cleaning boxes gradually approach the joint of the underground continuous wall. When they move to the designated position and the roller contacts and fits the joint of the lock pipe, screw the screw into the corresponding threaded groove to fix the position of the telescopic rod. S2. Turn on the driving motor, which drives the rotating rod to rotate. The eccentric wheel at the end of the rotating rod rotates accordingly. The eccentric wheel drives the swing rod to move through the eccentric rod. The swing rod drives the first slide to move back and forth on the slide rod through the fixed block. The first slide then drives the swing rod to swing through the connecting rod, thereby causing the wire brush to swing up and down to clean the slurry impurities at the joint of the lock pipe; S3. During the rotation of the eccentric wheel, the eccentric wheel cooperates with the resistance frame to drive the resistance frame to move back and forth. The resistance frame drives the U-shaped frame and the conduit to move back and forth through the cross bar. Water enters the conduit through the water supply pipe and is then sprayed out from multiple high-pressure nozzles through the water delivery pipe.

[0011] The present invention provides a water-rich sand layer underground continuous wall construction equipment and construction method thereof. It has the following beneficial effects: (1) The present invention can adjust the positions of the two cleaning boxes by cooperating with the telescopic cylinder and the adjustable telescopic rod, so that they are suitable for the width between the underground continuous walls of different adjacent slot sections. The wire brush can be swung back and forth by cooperating with the driving motor, the rotating rod, the eccentric wheel, the eccentric rod and the swing rod structure, which can effectively remove the slurry and impurities at the joints. At the same time, the high-pressure nozzle can be swung back and forth by cooperating with the eccentric wheel, the contact frame, the U-shaped frame and the conduit structure. The high-pressure nozzle can comprehensively flush the joints, assist the wire brush in cleaning, further improve the cleaning effect, avoid cleaning dead corners, improve the cleaning effect of the joints of the underground continuous wall lock pipe, and enable the underground continuous walls of adjacent slot sections to be closely connected, thereby reducing the risk of wall leakage to a certain extent.

[0012] (2) The present invention uses rollers to tightly contact the joints of the continuous wall lock pipes, which not only helps the equipment to move up and down stably, but also ensures that the wire brush always maintains good contact with the joint surface during the wall brushing process, thereby improving the stability and accuracy of the wall brushing operation.
