when the extrusion rod 85 extrudes spiral cement, the cutting edge of the extrusion rod 85 contacts the first elastic ring 1 and cuts the first elastic ring 1, and pigment in the annular cavity of the first elastic ring 1 flows to an external sedimentation tank along with the wall protection liquid, so that workers can conveniently determine the position of the extrusion rod 85 relative to the first elastic ring 1.
Example nine:
as shown in fig. 3-5, this embodiment discloses an underwater pile foundation drilling device, and on the basis of any one of the second to seventh embodiments, a supporting belt 7 of this embodiment is installed on the upper portion of the inner wall of the first closed bag 2, and a supporting rope 6 is a metal chain.
Wherein, the spiral direction of the metal chain is the same as the external bit rotation direction.
The working process and principle of the embodiment are as follows:
when the external drill bit drills to the junction of the soft stratum and the inclined hard stratum, the external drill bit continuously downwards drills to be easy to deviate, so that the drilling of the pile foundation is inclined, and the drilling quality of the pile foundation is affected.
After the external drill bit drills to the junction of the soft stratum and the inclined hard stratum, the first elastic ring 1, the second elastic ring 3, the cement bag 9, the first closed bag 2 and the second closed bag 13 are arranged at the position where pile foundation drilling is close to the inclined hard stratum in a descending mode, the external drill bit continues to downwards drill after cement is hardened in the cement bag 9, the rotating external drill bit wears out the contacted second closed bag 13, the side wall of the external drill bit contacts the inner side of the spiral cement, the spiral cement and a metal chain in the spiral cement limit the external drill bit to prevent the external drill bit from drilling deflection, when the metal chain at the local position in the spiral cement is exposed, the metal chain is limited by adjacent cement and still can limit the external drill bit, and leakage of a protection wall liquid can be delayed.
The spiral direction of the metal chain is the same as the rotation direction of the external drill bit, so that the risk that the metal chain is wound on the external drill bit is reduced.
Example ten:
as shown in fig. 1-3, this embodiment discloses an underwater pile foundation drilling device, the structure of which is substantially the same as that of the ninth embodiment, except that annular cavities are provided in the first elastic ring 1 and in the second elastic ring 3, and pigment with inconsistent colors is provided in the annular cavities of the first elastic ring 1 and the annular cavities of the second elastic ring 3.
The working process and principle of the embodiment are as follows:
the distance between the first elastic ring 1 and the second elastic ring 3 is further greater than the height of the external drill bit, the rotating external drill bit contacts with the second elastic ring 3, the second elastic ring 3 is damaged by contact friction between the second elastic ring 3 and the external drill bit, pigment in the second elastic ring 3 leaks out, and when pigment in the second elastic ring 3 appears in the color of flowing wall protection liquid, the spiral cement can be judged to limit the external drill bit.
When the metal chain in the spiral cement is wound on the external drill bit, the external drill bit rotates to enable the spiral cement to be broken and then wound on the external drill bit, the first elastic ring 1 is rolled or impacted and rubbed by the drill bit through the metal chain in the rotation process of the external drill bit, the first elastic ring 1 is broken, and the protection effect of the spiral cement on the wall of a pile foundation drilling hole is judged through the color change of flowing out wall protection liquid.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
