Detailed Description
The following describes embodiments of the present invention with reference to the accompanying drawings.
Referring to fig. 1-5, the temporary steel pipe pile with the arc-shaped partition plate comprises a main steel pipe 1, wherein a C-shaped lock catch 2 is fixed on the side wall of the main steel pipe 1, a T-shaped locking notch 3 is installed on the main steel pipe 1 at the symmetrical position of the C-shaped lock catch 2, auxiliary positioning supports 4 are symmetrically fixed on two sides of the T-shaped locking notch 3, a hole guiding steel casing 6 is installed between the auxiliary positioning supports 4, and an arc-shaped steel plate 5 is installed at the bottom of the hole guiding steel casing 6 and between the auxiliary positioning supports 4. Through adopting the interim steel-pipe pile of above-mentioned structure, the cofferdam is leading during the hole, through T type fore shaft and the 2 worker steels of being symmetrical in that T type fore shaft set up respectively along main steel pipe wall through-length in both sides, has formed the steel and has protected a supplementary positioning support when installing, treats that leading hole steel protects a section of thick bamboo 6 and transfers the back of targetting in place, leads hole steel and protects a section of thick bamboo 6 and supplementary positioning support temporary welding, has effectively controlled the plane position straightness that hangs down of drilling under the complicated geological conditions, has improved the pore-forming quality. Then, an arc-shaped steel plate welded on the outer side of the positioning tool steel through the lower part of the main steel pipe is used as a separation support, so that the hole guiding depth of the hole guiding steel protective cylinder 6 is reduced, and collapse and buried drilling of backfilled clay in the early-stage drilling in the drilling process are prevented; the rotary drilling drill bit collides with the arc-shaped steel plate to play roles in buffering and separating and supporting, and the drill bit is prevented from directly impacting the steel pipe pile when rotating.
Furthermore, the auxiliary positioning support 4 is made of an I-shaped steel material. Through its simple to operate of foretell auxiliary positioning support 4, can protect a section of thick bamboo 6 to the lead hole steel and install temporarily moreover.
Furthermore, the guide hole steel casing 6 and the arc-shaped steel plate 5 are concentrically arranged, and the inner diameter and the outer diameter of the guide hole steel casing are equal to each other.
Further, the auxiliary positioning support 4 is arranged along the whole length of the main steel pipe 1. The auxiliary positioning support 4 can be used for auxiliary positioning support of the whole main steel pipe 1.
Further, the arc-shaped steel plate 5 is arranged at the bottom of the guide hole steel casing 6 and along the whole length of the bottom of the main steel pipe 1. Through foretell arc steel sheet as separating the shelves and supporting, reduced the 6 leading hole degree of depth of leading hole steel casing, prevented among the drilling process in the drilling earlier stage backfill clay and appear collapsing, buried drill.
Further, the hole guiding steel protecting cylinder 6 is arranged at a certain height from the top end of the main steel pipe 1, and the bottom end of the hole guiding steel protecting cylinder 6 is flush with the bottom end of the T-shaped locking notch 3. By adopting the length arrangement, the pore-forming quality can be ensured.
Further, the length of the T-shaped locking notch 3 is smaller than that of the C-shaped lock catch 2. By adopting the length matching relationship, the connection strength and the reliability between two adjacent main steel pipes 1 are ensured.
Example 2:
in the construction process of the cofferdam fore shaft steel pipe pile pilot hole pile inserting, through a drilling mode of 1 hole site in advance, by utilizing a T-shaped fore shaft 3 and two auxiliary positioning supports 4 which are symmetrical to the T-shaped fore shaft 3 and are respectively arranged on two sides along the through length of the pipe wall of a main steel pipe 1, the auxiliary positioning supports when the pilot hole steel casing 6 is installed are formed, after the pilot hole steel casing 6 is put down in place, the pilot hole steel casing 6 is temporarily welded with the auxiliary positioning supports, the drilling plane position and the verticality under the complex geological condition are effectively controlled, and the hole forming quality is improved;
an arc-shaped steel plate 5 is welded on the outer side of the auxiliary positioning support 4 through the lower portion of the main steel pipe 1 to serve as a barrier support, so that the hole guiding depth of the steel casing is reduced, and collapse and buried drilling of backfilled clay in the early-stage drilled hole in the drilling process are prevented;
in the drilling process, the rotary drilling bit collides with the arc-shaped steel plate 5 to play a role in buffering and separating and supporting, so that the drill bit is prevented from directly impacting the main steel pipe 1 during rotation.
