TECHNICAL FIELD
[0001] The utility model relates to the field of construction positioner, specifically to a movable prestressed pipe pile inserts and hits positioner. BACKGROUND
[0002] Pipe pile inserts and hits positioning is an important link in building engineering, which requires accurately inserting the pipe pile into the predetermined position to ensure the quality and safety of the project. In the positioning process of pipe pile inserts and hits, the right-angle intersection method is generally used. First, the coordinates of a point (referred to as the measuring point) on the edge of the pile (for pipe pile, the corresponding tangent line) at a certain elevation are calculated according to the pile parameters such as pile coordinates. Then, the measuring point is projected vertically onto the front and side of the "L" shaped baseline. Next, the theodolite is set up at points A and B, and the 0° or 180° direction of the baseline is observed. The angle is turned to 90° or 270° to intersect and drive the corresponding measuring point of the pile, thereby controlling the position of the pile. However, this method is greatly affected by the site conditions of the construction site.
[0003] When large-scale construction is carried out, a large number of pipe piles need to be inserted and hit in the construction area. In the past, RTK was used for setting out, and bamboo poles were inserted to mark the position. During the construction process, the movement of transportation equipment, driving and pulling equipment, etc. can easily damage the setting-out point. Re-setting the point is time-consuming and labor-intensive, and the original point position is easily damaged, which reduces the accuracy of the subsequent construction. To address the above issues, a movable and firm positioner is developed, which can accurately position according to the design size and position of the design drawing. Therefore, the positioner itself must meet the design size of the design drawing, and the structure must be stable and firm. At the same time, it should be convenient to turn over. SUMMARY

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0020] like Figures 1-4 As shown, a movable prestressed pipe pile driving positioner of the present invention includes several positioning sleeves. The several positioning sleeves are detachably connected by steel bars 4 based on the same plane. The several positioning sleeves are arranged in a rectangular array, and the positioning sleeves include a row of semi-circular positioning sleeves 3 set at the edge and two rows of circular positioning sleeves 2.
[0021] In large-scale construction projects, a large number of pipe piles 6 need to be driven into the construction area. These numerous pipe piles 6 are arranged in a regular pattern. In the past, RTK (Real-Time Kinematic) was used for layout, with bamboo poles inserted for marking. However, the movement of transportation equipment and driving / pulling equipment during construction could easily damage the layout points. Re-laying the points was time-consuming and laborious, and the original points were easily damaged, reducing the accuracy of continued construction. To solve these problems, a movable and robust locator was developed. This locator can accurately position itself according to the design dimensions in the design drawings. Therefore, the locator itself must conform to the dimensions in the design drawings, have a stable and robust structure, and be easy to move around.
[0022] Through the above structure, several positioning sleeves are arranged in a rectangular array. Specifically, in order to facilitate use and improve accuracy, the number of positioning sleeves in the positioner is nine, forming a three-row, three-column structure, including circular positioning sleeve 2 and semi-circular fixing sleeve 21. Two columns of circular positioning sleeve 2 are on the left, while one column of semi-circular positioning sleeve 3 is on the right. During use, the first pile is driven into the foundation based on the on-site measurement results. Then, the first circular positioning sleeve 2 on the left is fitted into the first pile, using the position of the first pile as the base point. Then, all nine pipe piles 6 in the locator are installed in sequence. The pipe pile 6 in the rightmost semi-circular positioning sleeve 3 position only needs to be installed by abutting against the inner wall of the semi-circular positioning sleeve 3. After all nine pipe piles 6 are installed, the locator is slid off from above several pipe piles 6. Then, the leftmost row of circular positioning sleeves 2 of the locator is fitted onto the three rightmost pipe piles 6 among the nine pipe piles 6 that have been driven. Then, the remaining three pipe piles 6 in the positions of the circular positioning sleeves 2 and the three semi-circular positioning sleeves 3 are driven. In order to further improve the installation accuracy, the left two rows of circular positioning sleeves 2 can also be fitted onto the six rightmost pipe piles 6 among the nine pipe piles 6 that have been driven. Then, the remaining three pipe piles 6 in the positions of the semi-circular positioning sleeves 3 are driven. This can improve the driving accuracy of the pipe piles 6.
[0023] Since the whole locator includes nine positioning sleeves and the reinforcing bars 4 connected with the positioning sleeves, the size of the whole locator is large, and the locator is generally moved to the construction site after the construction in the factory. The locator can be repeatedly used, and the size of the locator needs to be considered for recycling after use to save storage space. Therefore, in an embodiment, the positioning sleeves include the central positioning sleeve 1, the circular positioning sleeves 2 and the semicircular positioning sleeves 3 which are movably connected to the central positioning sleeve 1. The circular positioning sleeves 2 and the semicircular positioning sleeves 3 surrounding the central positioning sleeve 1 are provided with sockets, and the sockets are used for detachable connection with the reinforcing bars 4 on the adjacent positioning sleeves. The circular positioning sleeves 2 and the semicircular positioning sleeves 3 surrounding the central positioning sleeve 1 are vertically rotatably connected to the central positioning sleeve 1 through the reinforcing bars 4.
[0024] The central positioning sleeve 1 is located at the central position of the nine positioning sleeves, and the other eight circular positioning sleeves 2 and semicircular positioning sleeves 3 are arranged around the central positioning sleeve 1. The central positioning sleeve 1 is rotatably provided with eight sockets, and the eight sockets can rotate up and down on the central positioning sleeve 1. One side of the eight peripheral circular positioning sleeves 2 and semicircular positioning sleeves 3 is also provided with a socket, and the other side is connected with the reinforcing bar 4. The reinforcing bar 4 on any one of the eight peripheral positioning sleeves is used for detachable connection with the socket on the adjacent positioning sleeve, and the socket on any one of the positioning sleeves is also detachably connected with the reinforcing bar 4 on the adjacent positioning sleeve. In the use process, the eight peripheral positioning sleeves are unfolded based on the central positioning sleeve 1, and when the use is completed and needs to be recycled, the reinforcing bar 4 and the socket on the eight peripheral positioning sleeves are separated, and are folded based on the central positioning sleeve 1, so as to reduce the volume of the locator, facilitate the storage of the subsequent locator, and save space.
[0025] In order to make the eight peripheral positioning sleeves of the locator stable when unfolded and used, in an embodiment, the central positioning sleeve 1 is rotatably provided with a plurality of support rods 5 on the side surface, and the other end of the plurality of support rods 5 is slidably sleeved on the corresponding reinforcing bar 4 on one side to form a triangular support structure. One end of the support rod 5 is connected to the bottom side of the central locator, and the eight peripheral positioning sleeves are above the support rod 5. The eight peripheral positioning sleeves correspond to eight support rods 5, and the support rod 5 and the reinforcing bar 4 form a structure similar to the ribs of an umbrella after being connected. The reinforcing bar 4 connected with the central positioning sleeve 1 of the eight peripheral positioning sleeves is provided with a positioning point, which is used for limiting the sliding connection of one end of the support rod 5 on the reinforcing bar 4. When the sliding connection of one end of the support rod 5 on the reinforcing bar 4 slides to the positioning point, the support rod 5 is clamped by the positioning point, so that the support rod 5 is in a supporting state, and the eight peripheral positioning sleeves are in an unfolded state. When recycling, the sliding connection of one end of the support rod 5 on the reinforcing bar 4 is separated from the positioning point.
[0026] In order to make the circular positioning sleeve 2 convenient to disassemble, in an embodiment, the circular positioning sleeve 2 comprises a fixed sleeve 21 and a movable sleeve 22, both of which are semicircular, the fixed sleeve 21 is connected to the reinforcing steel bars 4, and the movable sleeve 22 is rotationally connected with the fixed sleeve 21 and forms a circle; the abutting surfaces of the fixed sleeve 21 and the movable sleeve 22 are provided with movable buckles, the movable buckles can be used for disassembling the pipe piles 6 when separated, and the movable buckles can be used for limiting and fixing the pipe piles 6 when connected, so that the circular positioning sleeve 2 keeps a high position on the pipe piles 6.
[0027] In an embodiment, the central positioning sleeve 1 is provided with a level; through the level, the horizontal state of the positioner on the pipe piles 6 can be observed, and the height of different sides of the positioner can be adjusted according to the state of the level.
[0028] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content without departing from the technical solution of the present application, and any equivalent embodiments with equivalent changes and modifications are still within the scope of the present application.
