The lower parts of the four outer side ends of the cross-shaped bracket are respectively welded at the middle points of the four sides of the square frame. The axis of the bolt for connecting the prism is superposed with the axis of the steel casing. The utility model discloses can protect a section of thick bamboo upper end center at the steel with measuring prism accurate positioning, the accuracy and the straightness that hangs down that a section of thick bamboo position was protected to the steel are guaranteed in the real-time tracking measurement, have simple structure, cost of manufacture low, labour saving and time saving uses safe and reliable and excellent in use effect's advantage.
Description
Technical Field
The utility model belongs to a bridge pile foundation steel protects a construction measurement positioner.
Background
The construction of underwater pile foundations in highway bridges and wiring engineering adopts the erection of a fixed underwater platform, the long steel casing is arranged to ensure the stability of drilling, and rotary drilling is selected for use to form holes. When pile foundation steel protects a section of thick bamboo and transfers installation and squeeze into, require the steel to protect a section of thick bamboo center and pile foundation design center and keep vertical coincidence, especially aquatic pile foundation construction, the steel protects a section of thick bamboo and sets up and need many times to lengthen when following, and owing to need the pilot hole construction, needs real-time tracking to measure the steel and protects a section of thick bamboo coordinate position, otherwise easily causes the steel to protect a skew pile foundation design center, needs rework, influences construction speed and work efficiency. Therefore, the measurer frequently climbs the upper end of the steel casing to set points for measurement, which wastes labor and effort, and has the disadvantages of workload, poor accuracy of fixed points and low working efficiency.
Disclosure of Invention
The utility model aims at designing a bridge pile foundation steel protects a construction measurement positioner, can protect a section of thick bamboo upper end center at the steel with measuring prism accurate positioning, the real-time tracking is measured, guarantees that the steel protects the accuracy and the straightness that hangs down of a section of thick bamboo position, has simple structure, cost of manufacture low, labour saving and time saving, uses safe and reliable and excellent in use effect's advantage.
Therefore, the utility model discloses constitute by the bolt, a square frame's upper end is equipped with the cross bracket, and the lower extreme off-plate end portion of cross bracket is fixed as an organic whole with the middle part of the square frame four sides that correspond respectively, is equipped with the bolt that supplies the prism to connect usefulness on the central point of cross bracket.
The lower parts of the four outer side ends of the cross-shaped bracket are respectively welded at the middle points of the four sides of the square frame.
The axis of the bolt for connecting the prism is superposed with the axis of the steel casing.
The middle part of the inner side edge of the square frame is clamped on the outer wall of the upper end of the steel casing. The length of the inner side edge of the square frame is the same, and the length of each side of the cross-shaped bracket is the same.
Above-mentioned structural design has reached the utility model discloses a purpose.
The utility model discloses can protect a section of thick bamboo upper end center at the steel with measuring prism accurate positioning, the steel of trailing in real time protects a section of thick bamboo and measures, guarantees that the steel protects the accuracy and the straightness that hangs down of a position, has simple structure, cost of manufacture low, labour saving and time saving, uses safe and reliable and excellent in use effect's advantage.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in figure 1, the measuring and positioning device for the construction of the bridge pile foundation steel casing consists of bolts, a cross-shaped bracket 1 is arranged at the upper end of a square frame 2, the outer end part of the lower end surface of the cross-shaped bracket is respectively fixed with the middle parts of four sides of the corresponding square frame into a whole, and a bolt 3 for connecting a prism is arranged at the central point of the cross-shaped bracket.
The lower parts of the four outer side ends of the cross-shaped bracket are respectively welded at the middle points of the four sides of the square frame.
The axis of the bolt for connecting the prism is superposed with the axis of the steel casing. The middle part of the inner side edge of the square frame is clamped on the outer wall of the upper end of the steel casing. The length of the inner side edge of the square frame is the same, and the length of each side of the cross-shaped bracket is the same. The square frame and the cross-shaped bracket can be made of square edge wood or square steel pipes.
When the device is used, a prism for measurement is arranged on a bolt at the central point of the cross-shaped bracket, and then the inner frame edge of the square frame is clamped and fixed on the outer wall at the upper end of the steel casing. Actually measuring the center position of the steel casing to ensure that the center of the prism is superposed with the center of the steel casing; when the steel casing is put down and driven in, the central coordinate value of the steel casing represented by the prism is tracked and measured in real time, the central coordinate value is compared with the design coordinate of the pile foundation center to calculate a deviation value, and the position of the steel casing is adjusted according to the deviation value; after the steel casing is driven into the steel casing, the coordinates of the central point of the steel casing are rechecked again, and the installation precision of the steel casing is guaranteed to meet the requirement of tolerance. After use, the utility model is detached and can be used repeatedly.
In a word, the utility model discloses can protect a center in a steel with measuring prism accurate positioning, the accuracy and the straightness that hangs down that a steel protected a position are measured in real-time tracking, have simple structure, cost of manufacture low, labour saving and time saving uses safe and reliable and excellent in use effect's advantage. Can be popularized and used.
