The steel bushing box is pushed by the jack to control and adjust the lowering precision of the steel bushing box, the steel bushing box is lowered along the sliding of the guide wheels, and the steel bushing box wall plate cannot be damaged.
Description
Technical Field
The utility model belongs to the technical field of the bridge construction, a steel bushing box that relates to the construction of aquatic cushion cap is transferred, concretely relates to steel bushing box transfers direction limit structure with adjustable.
Background
The construction of the underwater bearing platform usually adopts a steel sleeve box as a temporary water retaining structure. After the steel sleeve box is integrally assembled, a lowering system is arranged on the steel casing for drilling construction, and the steel sleeve box is lowered to the designed elevation. To prevent the steel casing box from shifting due to water flow impact, a steel guide frame is usually welded on the steel casing. When the steel pouring box is lowered, the inner wall of the steel pouring box is in contact with the guide frame and can cause scratches, and the side plates of the steel pouring box are used as templates for concrete pouring of the bearing platform and can influence the flatness of the concrete of the bearing platform after being damaged; and the leading truck structure is fixed, if it has size error itself, can influence the precision of transferring of steel pouring jacket.
Disclosure of Invention
The utility model aims at the above-mentioned problem, a direction limit structure is transferred to steel bushing case with adjustable is provided, avoids causing the damage to the steel bushing case to guarantee that the steel bushing case transfers the precision.
The technical scheme of the utility model as follows:
the utility model provides a direction limit structure is transferred to steel pouring jacket with adjustable, the steel pouring jacket transfers its characterized in that through setting up the system of transferring on pile foundation drilling construction steel protects a section of thick bamboo: a notch is formed in the wall, facing one side of the steel casing box, of the steel casing, a bracket is arranged in the steel casing and comprises a platform and an inclined strut, one end of the platform and the lower end of the inclined strut are welded to the inner wall of the steel casing, the upper end of the inclined strut is welded to the bottom face of the other end of the platform, a counter-force seat is welded to the top face of the welding end of the platform and the inclined strut, an ejector rod is horizontally arranged on the platform, a guide wheel is arranged at the front end of the ejector rod and protrudes out of the steel casing from the notch in the wall of the steel casing, and a jack is horizontally arranged between the rear end of the ejector rod and the counter-force seat.
The utility model makes full use of the characteristic of large rigidity of the steel casing as a supporting structure, controls and adjusts the plane position of the steel casing box by using the jack, and can ensure the lowering precision of the steel casing box; the hard plastic pulley group is adopted to guide the sleeve box, so that the wall plate of the steel sleeve box is not damaged; constructors operate on the platform in the steel casing, and construction safety can be guaranteed.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, a notch is formed in one side, opposite to a steel jacket box 2, of a cylinder wall of a steel casing 1, a bracket is arranged in the steel casing, the bracket comprises a platform 3 and an inclined strut 4, one end of the platform 3 and the lower end of the inclined strut 4 are welded to the inner wall of the steel casing 1, the upper end of the inclined strut is welded to the bottom surface of the other end of the platform, a counter-force seat 5 is welded to the top surface of the welding end of the platform and the inclined strut, a top rod 6 is horizontally arranged on the platform, a guide wheel 7 is arranged at the front end of the top rod, the front end of the top rod protrudes out of the steel casing from the notch in the wall of the steel casing, and a jack 8 is horizontally arranged between the rear end of the top rod and the counter-force seat.
Adopt the utility model discloses a work progress as follows:
after the drilling construction of the pile foundation is completed, a steel pouring jacket assembling and transferring system is erected by utilizing the steel pile casing for drilling construction. A notch is formed in the wall, close to the upper end of the steel casing, of the outer side cylinder of each steel casing towards the 4 side walls of the steel casing box, a bracket and a counter-force seat are welded below the notches in the steel casings, and the counter-force seat can adopt a bracket structure. When the steel sleeve box is lowered, a mandril is arranged on the bracket platform, a jack is arranged between the rear end of the mandril and the counterforce seat, and the mandril is pushed by the jack, so that a guide wheel at the front end of the mandril is tightly propped against the inner wall of the steel sleeve box to limit the horizontal displacement of the steel sleeve box; the steel bushing box is placed down along the guide wheel, and the guide wheel can adopt rigid plastic or rubber wheel, avoids fish tail steel bushing box inner wall. In the process of lowering, monitoring the plane position of the steel pouring jacket at any time, if the steel pouring jacket deviates to one side, properly contracting a jack on the side, pushing the steel pouring jacket to the other side through the jack on the other side, and adjusting the plane position of the steel pouring jacket to ensure the lowering precision of the steel pouring jacket; after the adjustment is in place, all jacks are tightly jacked, and the steel sleeve box is continuously lowered.
