Anti-deviation device for underground diaphragm wall grooving

Abstract

The utility model relates to the technical field of underground diaphragm wall grooving, in particular to an underground diaphragm wall grooving anti-deviation device which comprises a rectangular flat plate, a plurality of telescopic rods are welded to the bottom of the rectangular flat plate, each telescopic rod is composed of an outer rod, an inner rod and a locking device, external threads are arranged at the bottom of each inner rod, and a mechanical sleeve is welded to a grab bucket and used for being detachably connected with the corresponding inner rod. The utility model solves the problems that when the corner part of the foundation pit is grooved by a grooving machine, the grab bucket is easy to deviate, so that the formed hole deviates, and the reinforcement cage cannot be lowered.

Description

Technical Field

[0001] The utility model relates to the technical field of ground-connected wall troughing, in particular to a ground-connected wall troughing anti-deviating device. Background Art

[0002] As an important method for supporting deep foundation pits, underground diaphragm walls are widely used due to their high rigidity, integrity, durability, and excellent anti-seepage properties. Large foundation pits generally adopt L- or Z-shaped corners. Therefore, when trenching machines are used to form trenches at these corners, the grab bucket is prone to offset, causing the hole to be skewed and preventing the steel cage from being lowered. In this situation, the computer in the cab adjusts the left and right movement of the guide plate to stabilize the bucket. However, the guide plate only moves 5 cm, making it impossible to adjust when the trenching gap is large. Utility Model Content

[0003] The purpose of the utility model is to provide a ground-connected wall groove anti-deviating device to solve the problems raised in the above background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A ground-connected wall trough anti-deviation device includes a rectangular flat plate with several telescopic rods welded to the bottom. The telescopic rods consist of an outer rod, an inner rod and a locking device. The bottom of the inner rod is provided with an external thread. A mechanical sleeve is welded on the grab bucket for detachable connection with the inner rod.

[0006] As a further solution of the present invention: the rectangular flat plate is made of 20 mm thick steel plate, with a length of 100 cm and a width of 20 cm.

[0007] As a further solution of the present invention: the telescopic rods are arranged in two rows, with a total of 20 rods.

[0008] Compared with the existing technology, the beneficial effect of the utility model is that when the troughing machine is troughing downward, the device fills the gap between the grab bucket and the trough wall tightly, preventing the grab bucket from offsetting due to uneven force when grabbing soil in the trough, effectively ensuring the verticality of the trough and preventing the formation of inclined holes. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 This is one of the three-dimensional structural diagrams of the present invention.

[0010] Figure 2 This is the second schematic diagram of the three-dimensional structure of the present invention.

[0011] Among them: 1 rectangular plate, 2 outer rods, 3 inner rods. DETAILED DESCRIPTION

[0012] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0013] See also Figure 1-2 The present invention provides a ground-connected wall trench anti-deviating device, which comprises a rectangular flat plate 1 with a plurality of telescopic rods welded to the bottom thereof. The telescopic rods are composed of an outer rod 2, an inner rod 3, and a locking device. The telescopic rods are conventional and can be selected at will, so they will not be described in detail here. The bottom of the inner rod 3 is provided with an external thread, and a mechanical sleeve is welded on the grab bucket for detachable connection with the inner rod 3. When the device is used, the inner rod 3 is screwed into the corresponding mechanical sleeve, and then the outer rod 2 and the inner rod 3 are sleeved together and locked according to the use length. When not in use, they are removed. The telescopic rods can be adjusted according to the distance between the trench wall and the grab bucket, so that the device can adapt to different spacing requirements and can be used in a wider range of spacing.

[0014] Preferably, the rectangular flat plate 1 is made of 20 mm thick steel plate, has a length of 100 cm and a width of 20 cm. The telescopic rods are arranged in two rows, with a total of 20.

[0015] A total of four devices are processed, three of which are set on the side plate and one on the correction plate on the grab bucket body on the side of the trough back water surface.

[0016] The preferred embodiments of the present application are described in detail above, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of the present application.
