Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete vibrating equipment, in particular to a construction equipment used for vibrating and backfilling a recoverable underground continuous wall groove. Background Art
[0002] In foundation pit support, underground continuous wall support is widely used in multiple construction scenarios, among which recyclable underground continuous wall is gradually developing. When carrying out the construction of recyclable underground continuous wall, it is usually necessary to first excavate the trench for the underground continuous wall, and then install the underground continuous wall inside the trench. After the construction inside the foundation pit is completed, the foundation pit is backfilled, and the underground continuous wall is removed after the backfilling operation is completed. However, in the process of removing the underground continuous wall, the trench needs to be backfilled, but due to the constraints of the trench space and construction equipment during backfilling, the soil or slurry backfilled deep in the trench cannot be fully vibrated and backfilled, which often easily leads to uneven settlement of the site after the foundation pit is backfilled.
[0003] Obviously, there are prominent difficulties in vibrating and backfilling the recyclable underground continuous wall trench. Compared with the traditional foundation pit trench construction, the construction space of the recyclable underground continuous wall trench is narrower and deeper. Due to the limitation of the cross-sectional space of the recyclable underground continuous wall trench, it is much more difficult for construction workers to vibrate and backfill inside the trench. At present, there is no suitable instrument and equipment on the market specifically for vibrating and backfilling the recyclable underground continuous wall trench. If a small vibrator is used, it is impossible to operate the deeper area inside the trench during construction, which leads to uneven vibration backfilling. Utility Model Content

[0028] To elaborate, in this embodiment, the construction equipment for vibrating and backfilling a recyclable underground continuous wall trench comprises: a vertical rod 1, a supporting device 2, a vibrating device 3 and a pumping device 4 for transmitting backfill materials. The supporting device 2 is provided with a horizontal frame 21 and a first motor 22, and the first motor 22 is installed above the horizontal frame 21. The vertical rod 1 is slidably connected to the horizontal frame 21. The vibrating device 3 is provided with a connecting frame 31, a vibrating head 32 and a second motor 33.

The first motor 22 drives the vertical rod 1 to rise and fall along the depth direction of the underground continuous wall trench, and the vertical rod 1 drives the height position of the vibrating device 3 to change.
[0029] When vibrating and backfilling the inner space of the trench, the specific position of the vibrating device 3 inside the underground continuous wall trench is determined by controlling the rise and fall of the vertical rod 1.
