As an improvement of the invention, the connecting block is a square block, and the side length of the connecting block is less than or equal to the width of the L-shaped connecting groove.

As an improvement of the invention, a stop block is arranged above the connecting block.

As an improvement of the invention, the casing reinforcing hoop is provided with a round hole, and the round hole is arranged at the lower edge of the L-shaped connecting groove in height.

The use method of the detachable pile casing structure matched with the rotary drilling rig provided by the invention comprises the following steps:

during construction, at least two protection cylinders are matched for use, a connecting block of an upper protection cylinder is aligned with a vertical groove of an L-shaped connecting groove of a lower protection cylinder and inserted into the vertical groove, the upper protection cylinder is rotated after reaching the bottom to enable the connecting block to be clamped in a transverse groove of the L-shaped connecting groove, an inserting plate is inserted into the vertical groove of the L-shaped connecting groove to enable the connecting block to be incapable of being rotated out, and the upper protection cylinder and the lower protection cylinder are locked;

when the construction is finished, the inserting plate is taken out, the upper protecting cylinder is rotated reversely, the connecting block is separated from the L-shaped connecting groove, and the upper protecting cylinder can be detached from the lower protecting cylinder.

The invention has the beneficial effects that:

the detachable pile casing structure matched with the rotary drilling rig is exquisite in structure, convenient and quick to mount and dismount, and capable of saving a welding process, so that field operation procedures are simplified, time and labor are saved, and construction progress is accelerated.

Detailed Description

The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in the figure, the invention provides a detachable pile casing structure matched with a rotary drilling rig, which is used for the rotary drilling rig. When in use, at least two protective cylinders are matched for use, and each protective cylinder comprises a protective cylinder main body 1, a protective cylinder reinforcing hoop 2, a connecting block 3 and a stop block 4. An inserting plate 6 is additionally arranged.

Protect a 1 top of a main part and be equipped with L type spread groove 5 (including the cross slot with erect the groove, the cross slot is the L type with erecting the groove and arranges), protect a reinforcement hoop 2 and set up in the 5 outsides of L type spread groove, protect 1 lateral wall below of a main part evenly to be equipped with connecting block 3, the quantity and the position of connecting block 3 are supporting with L type spread groove 5.
