Description

Technical Field

[0001] The utility model relates to the technical field of double casings, in particular to a double casing structure used for underwater pile foundation construction. Background Art

[0002] The construction of bored piles is divided into two parts: hole formation and pile formation. Therefore, the inspection of pile foundation can be divided into two parts: hole formation quality inspection and pile formation quality inspection. Among them, hole formation is the first link in the construction of bored piles. Since the hole formation operation is completed underground and underwater, the quality control is difficult. Complex geological conditions or mistakes in construction may cause hole collapse, diameter reduction, pile hole deviation, excessive sediment thickness and other problems. Pile quality inspection can be divided into bearing capacity inspection and integrity inspection.

[0003] The existing double casing structure has certain drawbacks. When the double casing is installed, when the position of the casing needs to be changed, the position of the inner casing cannot be changed directly, resulting in loss of manpower and money. Utility Model Content

Since the electric telescopic rod 9 slides inside the moving groove 8, the inner casing 2 can be changed inside the outer casing 1. At this time, there is no need to lower the outer casing 1 again, thereby causing loss of manpower and money. The electric telescopic rod 9 is the prior art. The working principle of the electric telescopic rod is mainly based on motor drive and spiral combination transmission structure. In the electric telescopic rod, the motor is the core component, which controls the extension and contraction of the telescopic rod by rotation. When the motor is started, the output shaft generates a rotational force, which is transmitted to the telescopic rod through the connector of the telescopic rod, thereby driving the extension and contraction of the telescopic rod. When the motor stops working, the telescopic rod will also stop extending and be fixed at the current length.

[0032] During operation, the sealing ring 12 cooperates with the bottom plate 3 and the connecting plate 4 to prevent external water and cement from entering between the outer casing 1 and the inner casing 2 .

[0033] See also Figure 1-4 The present invention provides a technical solution: the two moving blocks 10 are provided with a card slot 11 at their ends which are far away from each other.
