Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Reference is made to the accompanying drawings. The utility model discloses be equipped with the U-shaped piece 1 of opening level orientation and connect the fixed plate 4 in this U-shaped piece 1 both sides. The U-shaped part 1 is formed by vertically arranging three rectangular steel plates with the same specification in pairs, and is respectively provided with two parallel steel plates 3 which are parallel to each other and side steel plates 2 which are vertically welded with the parallel steel plates 3. The top three sides l of the U-shaped member 11Bottom three sides l of a U-shaped part of equal length2Side length of same length l1、l2The sum of the edge diameter value of the corresponding square pile 5 and the thickness of 2 times of the parallel steel plate or the side steel plate and 10mm is equal, so that the distance from the inner wall of each surface of the U-shaped part 1 to the outer wall of the square pile 5 is controlled to be less than or equal to 5mm when the corresponding square pile 5 is positioned in the middle of the U-shaped part 1. The other side lengths of the U-shaped element 1 can be determined as a function of the actual situation.
The fixing plates 4 are perpendicular to the surfaces of the parallel steel plates 3 and are welded to the bottom edges of the two parallel steel plates 3 respectively. The fixed plate 4 is parallel to the bottom edge l of the parallel steel plate2The side length of the connection is equal to the bottom side length of the parallel steel plates, and the fixing plate 4 is arranged not to exceed the U-shaped part 1. The remaining side length of the fixing plate 4 can be adjusted according to actual conditions.
Therefore, the overall structure of the auxiliary device is symmetrical. In particular, the steel plate used for the auxiliary device is made of structural steel with the strength grade of Q235 and above, and the thickness is determined according to welding and firmness.
The auxiliary device can be used in the following two ways:
the use method is one. The auxiliary device is welded in the center of the counterweight support frame of the static pressure pile driver and moves together with the pile driver to be matched with construction. After single solid square pile central point coordinate of concrete prefabrication and azimuth location unwrapping wire are accomplished, can remove static pressure stake machine counter weight support frame, make the utility model discloses trilateral parallel in trilateral and the single pile azimuth unwrapping wire in U-shaped piece opening bottom, the square pile freely passes the U-shaped piece, and static pressure stake machine head center becomes a straight line with U-shaped piece opening center and square pile central point coordinate, treats that the square pile bottom can begin to execute the square pile after reacing location unwrapping wire department.
And the second use mode. The auxiliary device is used independently and is not welded with a counterweight support frame of the static pressure pile driver. After single prefabricated solid square pile central point coordinate of concrete and azimuth location unwrapping wire are accomplished, remove this auxiliary device, make the utility model discloses trilateral parallel wantonly in trilateral and the single pile azimuth unwrapping wire in U-shaped piece opening bottom, remove the counter weight support frame again, push down the perpendicular welded steel sheet that links to each other with this auxiliary device's U-shaped piece opening both sides bottom and make it fixed, the same with first scheme, the square pile freely passes the U-shaped piece, static pressure stake machine head center becomes a straight line with U-shaped piece opening center and square pile central point coordinate, can begin to execute the square pile after the square pile bottom reachs location unwrapping wire department.
In conclusion, in the single-pile construction process, because the three sides of the concrete prefabricated solid square pile 6 are surrounded by the steel plates on the three sides of the U-shaped part and are parallel to the three sides of the U-shaped part in a one-to-one correspondence mode, only small gaps exist between the three sides of the U-shaped part, and therefore the verticality and the azimuth angle control precision of the square pile are greatly improved, the workload of measuring personnel is reduced, and the single-pile construction time is shortened.
It should be noted that the above describes exemplifying embodiments of the invention. However, it should be understood by those skilled in the art that the present invention is not limited to the above-described embodiments, which are only illustrative of the principles of the present invention, and that various changes and modifications may be made without departing from the scope of the present invention, and the changes and modifications are intended to fall within the scope of the present invention as claimed.
