Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm wall construction, in particular to a device for simultaneously sawing and slotting a diaphragm wall and pouring a wall while sawing continuously. Background Technique

[0002] The TRD method is a construction process in which a cutting box equipped with a cutting chain and cutter heads is inserted into the ground to the designed depth. While longitudinally cutting and laterally advancing to form a slot, cement slurry is injected into the foundation to fully mix and stir with the original foundation to form an equal-thickness continuous wall underground.

[0003] In the patent document with the publication number: CN206418489U, a device for simultaneously sawing and slotting a diaphragm wall and pouring a wall while sawing continuously is disclosed, which involves an isolation box installed on one side of a chain saw type cutter box; the chain saw type cutter box is provided with a soil discharging device for transporting loose soil to the top of the chain saw type cutter box and discharging it, filling super-retarding concrete into the concrete pouring section, and using the side pressure of the concrete to push the whole chain saw type cutter box and the isolation box forward. At the same time, the loose soil is continuously discharged by the soil discharging device to release the space of the soil cutting section and continuously supplement the concrete behind the isolation box; preferably, the concrete is super-retarding concrete, and its final setting time is greater than or equal to hours; the pressure of filling super-retarding concrete in the concrete pouring section provides part of the top thrust of the chain saw type cutter box, and the steel reinforcement cage is timely lowered into the unhardened concrete in the concrete pouring section to form a seamless reinforced concrete underground continuous wall.

[0004] However, during the use process, the chain saw type cutter box on the left side of the isolation box uses the pressure of the concrete to provide part of the top thrust for the chain saw type cutter box and drive it to move, and then the steel reinforcement cage is placed into the unhardened concrete on the right side of the isolation box. However, when the isolation box moves to the left, the concrete will also flow to the left along with the movement of the isolation box. After the steel reinforcement cage is placed into the unhardened concrete, in the case of insufficient stability, the steel reinforcement cage will tilt along with the flow of the concrete. Since the tilt of the steel reinforcement cage will cause the stress structure after the formation of the diaphragm wall to be not strong enough, it will cause the problem of poor quality of the diaphragm wall.

[0005] Therefore, it is necessary to provide a device for simultaneously sawing and slotting a diaphragm wall and pouring a wall while sawing continuously, which is convenient for positioning the steel reinforcement cage to solve the above technical problems. Content of the Utility Model

[0024] Among them, the translation mechanical device 2 can drive the sawing mechanism 4 to move left and right, and can drive the sawing mechanism 4 to move up and down on the outside of the slide rail by winding and unwinding the steel wire rope.

A rotating rod 54 is inserted inside the guiding ring 53, and the outer side of the rotating rod 54 is screwed with the through hole at the top of the sleeve 52; by arranging the guiding ring 53 inside the sleeve 52, when the rotating rod 54 moves inside the sleeve 52, the guiding ring 53 can improve the stability of the movement of the rotating rod 54, and at the same time, the guiding ring 53 is convenient for preventing the rotating rod 54 from shaking left and right.

[0030] Reference Figure 1 、 Figure 2 and Figure 3 As shown, a compaction block 55 is connected to the bottom of the rotating rod 54. Elliptical blocks 56 are installed on both sides of the bottom of the sleeve 52, and the outer sides of the elliptical blocks 56 are in clamping fit with the inside of the steel reinforcement cage 6; when the rotating rod 54 drives the compaction block 55 to move downward, the bottom of the compaction block 55 contacts the outer sides of the elliptical blocks 56, and the elliptical blocks 56 are deflected and clamped and fixed with the inside of the steel reinforcement cage 6.

[0031] Reference Figure 1 、 Figure 2 and Figure 3 As shown, a limiting ring is connected to the outer side of the rotating rod 54. A buffer spring 57 is sleeved on the outer side of the rotating rod 54. The top of the buffer spring 57 is connected to the bottom of the limiting ring, and the bottom of the buffer spring 57 is connected to the top of the guiding ring 53; by arranging the buffer spring 57 on the outer side of the rotating rod 54, it is avoided that during the process of vibrating the concrete, the steel reinforcement cage 6 shakes, the rotating rod 54 deflects due to the shaking, and the rotating rod 54 drives the compaction block 55 to separate from the elliptical block 56, affecting the clamping stability of the elliptical block 56 and the steel reinforcement cage 6.

[0032] It should be noted that: a connecting pipe is arranged between the partition plate and the cutting box 42.

[0033] The working principle of a continuous sawing and grooving and synchronous grouting wall-forming device for diaphragm walls provided by the present utility model is as follows:

[0034] During use, the translation mechanical device 2 is started to drive the slide rail to move left and right, and the winding drum of the steel rope drives the transmission box 41 to move. The transmission box 41 drives the track block to move up and down along the outside of the slide rail. During the left and right translation of the translation mechanical device 2, the transmission box 41 drives the cutting box 42 to move left and right. The cutting box 42 drives the cutting chain 43 to rotate. The cutting chain 43 drives the cutting tool of the housing to rotate. The cutting tool saws the soil body 1, and the sawed-off mud blocks are removed from the inside of the cutting groove of the soil body 1 through the cutting tool. Then, concrete is injected into the bottom of the positioning plate 51. When the concrete uses the concrete pouring section to fill and provide partial top thrust to push the isolation plate to move, to avoid the situation that during the process of the concrete pushing the isolation plate and the positioning plate 51 to move, since the isolation plate moves to the left, the space on the right side of the isolation plate increases, and the concrete will flow to the left. During the flowing process of the concrete, it will drive the steel reinforcement cage 6 to tilt. Before injecting the concrete, by inserting the bottom of the sleeve 52 into the round hole at the top of the steel reinforcement cage 6, and then rotating the rotating rod 54, the rotating rod 54 moves downward along the thread inside the sleeve 52. The rotating rod 54 drives the compaction block 55 to move downward. The bottom of the compaction block 55 fits against the outside of the elliptical block 56, and the elliptical block 56 deflects. The other side of the elliptical block 56 is clamped and fixed inside the steel reinforcement cage 6. When the concrete pushes the isolation plate to move, the isolation plate drives the steel reinforcement cage 6 to move through the positioning plate 51, avoiding the steel reinforcement cage 6 from tilting and affecting the structural firmness of the diaphragm wall. When vibrating the concrete, the steel reinforcement cage 6 will vibrate. To avoid the situation that the rotating rod 54 deflects due to vibration and the compaction block 55 drives the separation from the elliptical block 56, affecting the clamping stability of the elliptical block 56 and the steel reinforcement cage 6, a buffer spring 57 is arranged on the outside of the rotating rod 54, facilitating reducing the vibration frequency of the rotating rod 54 by using the extrusion of the buffer spring 57. When it is necessary to lower the steel reinforcement cage 6, by rotating the rotating rod 54, the compaction block 55 is separated from the elliptical block 56. Due to the gravity of the steel reinforcement cage 6 itself, it will drive the elliptical block 56 to rotate, and finally the steel reinforcement cage 6 is separated from the elliptical block 56.

Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
