Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a jack leveling structure for steel pipe pile pier construction. Background Technology

[0002] During bridge construction, underground foundation piles need to be connected to surface piers to support the bridge deck. Existing methods involve drilling holes in the ground, inserting underground reinforcing cages, injecting concrete into the holes to form the piles, with the underground reinforcing cages protruding above ground. Then, surface reinforcing cages are connected to the underground cages, and concrete is poured on top to form the piers. This method is time-consuming; the concrete cannot repeatedly fill the inner and outer parts of the underground reinforcing cages, resulting in voids within the piles; the soil around the borehole walls easily seeps into the concrete, leading to wasted concrete and poor pile quality; and coaxial alignment of the underground and above-ground parts is inconvenient. Therefore, steel pipe pile piers have been designed. These steel pipe pile piers require leveling during construction, but currently, there is no suitable leveling equipment for this purpose. Utility Model Content

[0003] The present invention aims to provide a jack leveling structure for steel pipe pile pier construction, which solves the problem of the lack of a leveling structure for steel pipe pile pier construction, thus restricting the construction of steel pipe pile piers.

[0004] To achieve the above objectives, this utility model employs the following technology: a jack leveling structure for steel pipe pile pier construction, characterized in that it includes a plumb bob, three jacks, three upper support seats mounted on the steel pipe pier, and three lower support seats mounted on the steel pipe pile. One end of each of the three jacks is supported on one of the three lower support seats, and the other end is supported on one of the three upper support seats. The plumb bob includes a hammer head and a suspension line connected to the lower end of the hammer head. The upper end of the suspension line is connected to the steel pipe pier. The verticality of the steel pipe pier is determined by observing whether the suspension line is parallel to the steel pipe pier; if it is not vertical, the jacks are raised or lowered to achieve verticality. This structure can be used to verticalize the steel pipe pier connected to the steel pipe pile.

[0005] Preferably, the system also includes a lower clamp fastened to the steel pipe pile, and the lower support seat is connected to the lower clamp and thus connected to the steel pipe pile. This facilitates the connection of the lower support seat to the steel pipe pile.

[0006] Preferably, the lower support is welded to the lower clamp. This ensures a reliable and compact connection.

[0007] Preferably, the upper surface of the lower support is provided with a limiting recess, and the jack is supported in the limiting recess. This can improve the reliability of supporting the jack.

[0008] Preferably, the lower support base is evenly distributed along the circumference of the steel pipe pile, and the upper support base is evenly distributed along the circumference of the pier steel pipe. This provides good reliability during support and quick leveling.

[0009] Preferably, the system also includes an upper clamp fastened to the pier steel pipe, and the upper support seat is connected to the upper clamp and thus to the pier steel pipe. This facilitates the connection of the upper support seat to the pier steel pipe.

[0010] Preferably, the upper support is welded to the upper clamp. This ensures a reliable and compact connection.

[0011] Preferably, the upper end of the suspension line is connected to one end of a suspension rod, the other end of the suspension rod is connected to the upper end of a vertical support rod, and the lower end of the vertical support rod is connected to an upper support base. This facilitates fixing the plumb bob to the pier steel pipe and allows for easy reuse.

[0012] Preferably, there are three plumb bobs, each connected to one of the three upper support bases. This facilitates the inspection of verticality.

[0013] Preferably, the connection points of the three plumb lines with the suspension rod are equidistant from the axis of the pier steel pipe. Each of the three lower support seats is equipped with a scale extending radially along the steel pipe pile. The scale value corresponding to the scale line is the distance from the center line of the steel pipe pile. In use, the plumb lines of the three plumb lines are aligned to the same scale value, at which point the pier steel pipe and the steel pipe pile are coaxial and vertical. This facilitates adjustments for coaxiality and verticality.

[0014] Beneficial effects: It can level and center the steel pipes of the pier connected to the steel pipe pile; the leveling and centering is convenient and accurate. Attached Figure Description
