Technical Field

[0002] At present, in the soft foundation treatment construction, it is often necessary to apply a large number of various types of pile foundations to improve the bearing capacity of the soft foundation, and cement soil mixing piles are a more common type of piles. In the actual construction process, the pile foundation needs to be staked out first, that is, in the construction process of the pile foundation, the specific position of the pile position is determined by measurement and positioning technology, and it is marked on the ground. In the prior art, a mixing pile pile driver is required in the forming process of the mixing pile. Since the mixing pile pile driver is mostly operated on a soft foundation, it is easy to have an offset relative to the position of the stakeout point during work, which will cause the final pile to be offset. Therefore, the position of the pile needs to be detected after the pile is formed. If the number of mixing piles is large, the workload of the mixing pile stakeout and the detection of pile position offset is large, and the work efficiency is low. Summary of the invention

In the actual application process, it is necessary to first input the coordinates of the engineering projector 1 to perform preliminary positioning, and then the design coordinates of the mixing pile to be constructed can be input into the engineering projector 1. The engineering projector 1 can project corresponding laser rays. The intersection of the laser rays projected by the engineering projectors 1 on both sides of the pile position is the design coordinates and design elevation of the pile position. Before the pile foundation construction, the pile positions can be batch staked out by the cooperation of the two engineering projectors 1. After the pile foundation construction is completed, the engineering projector 1 can be used again to cooperate to batch detect the status of the pile position deviation hole, which is easy to operate and effectively improves the work efficiency of the mixing pile stakeout and the detection of pile position deviation.

[0032] Reference Figure 2 , Figure 3 and Figure 4The bracket 2 includes a support column 3, one end of which is provided with a mounting platform 31 for installing the engineering projector 1. Since the engineering projector 1 is of high value, the engineering projector 1 can be fixed to the mounting platform 31 by means of bolts. The engineering projector 1 and the mounting platform 31 are detachably connected, which is convenient for the subsequent storage and storage of the engineering projector 1 and the bracket 2. A supporting ring block 4 is integrally formed at the other end of the supporting column 3, and the supporting ring block 4 is coaxially arranged with the supporting column 3.

The locking assembly includes locking blocks 39 arranged at both ends of the adjustment area 37, and the end of the locking block 39 away from the adjustment area 37 is flush with the storage area 36 or the locking area 38. A locking groove 391 for the locking block 39 to slide is opened on the support column 3, and the locking block 39 can slide to be embedded in the locking groove 391. A locking elastic member is provided on the support column 3 for pushing the locking block 39 to cooperate with the outside of the locking groove 391. In the embodiment of the present application, the locking elastic member is a locking spring 392, one end of the locking spring 392 is fixed to the locking block 39, and the other end of the locking spring 392 is fixed to the support column 3. The control block 5 located in the storage area 36 or the locking area 38 is not easy to slide toward the adjustment area 37 under the action of the locking block 39. When the control block 5 is located in the storage area 36, ​​the support rod 41 rotates to the storage state. When the control block 5 slides to the adjustment area 37 and fits with the locking block 39 close to the locking area 38, the support rod 41 rotates to the supporting state. When the control block 5 slides to the locking area 38, the drilling block 34 slides out of the drilling cavity 341. Through the setting of the locking block 39, it is convenient to determine the state of the bracket 2 on the one hand, and it is convenient to control the sliding and locking of the control block 5 on the other hand.

[0044] Reference Figure 2 , Figure 3 and Figure 4A locking arc surface 393 is provided at one end of the locking block 39 away from the adjustment area 37. Through the setting of the locking arc surface 393, when the control block 5 slides from the storage area 36 toward the locking area 38 or from the locking area 38 toward the storage area 36, ​​it is only necessary to release the locking block 39 from the sliding of the control block 5 once, which is convenient for the use of the bracket 2.

[0045] Reference Figure 2 , Figure 3 and Figure 4 The end of the support portion 32 away from the support ring block 4 is rotatably connected with an adjusting block 6, and the adjusting block 6 can only rotate relative to the support portion 32, so that the adjusting block 6 is threadedly connected to the sliding portion 33, and a limit block 332 is fixed on the inner wall of the adjusting cavity 331. In the embodiment of the present application, there are four limit blocks 332, and the four limit blocks 332 are arranged in a circular array with the axis of the support portion 32 as the center. A limit groove 333 cooperating with the limit block 332 is provided on the sliding portion 33. When the adjusting block 6 rotates, the sliding portion 33 can slide relative to the support portion 32 under the action of thread transmission, and under the cooperation of the limit block 332 and the limit groove 333, the rotation of the sliding portion 33 is effectively limited, and the sliding of the sliding portion 33 in the adjusting cavity 331 is guided, thereby improving the reliability of driving the sliding portion 33 to slide through the rotation of the adjusting block 6.

[0046] Reference Figure 2 , Figure 3 and Figure 4 A plurality of placement grooves 61 are provided on the outer wall of the adjustment block 6, and the plurality of placement grooves 61 are arranged in a circular array with the axis of the adjustment block 6 as the center. By setting the placement grooves 61, the friction between the adjustment block 6 and the hand is increased, thereby facilitating the rotation of the adjustment block 6 and improving the stability of the sliding of the sliding part 33 controlled by the rotation of the adjustment block 6.

[0047] Reference Figure 2 , Figure 3 and Figure 4 A placement block 532 is fixedly provided on the end wall of the locking sliding portion 53 facing one end of the adjusting block 6. When the control block 5 is located in the storage area 36, ​​the placement block 532 is embedded in the placement groove 61. The placement block 532 cooperates with the placement groove 61 to lock the rotation of the adjusting block 6, so that when the bracket 2 is in the storage state, the sliding portion 33 is not easy to slip relative to the supporting portion 32 under the action of other external forces, thereby reducing the possibility of damage to the bracket 2 and extending the service life of the bracket 2 to a certain extent.

[0048] The implementation principle of the device for batch staking out and detecting pile position deviation of the embodiment of the present application is as follows: before batch staking out the mixing piles, positions for placing engineering cameras are first determined on both sides of the pile group to be constructed, and then brackets 2 are fixed at these two positions.

[0049] First, move the bracket 2 until the support ring block 4 is pressed against the ground. At this time, the control block 5 is in the storage area 36, ​​and the placement block 532 on the control block 5 is located in the placement groove 61 of the adjustment block 6. Press the locking block 39 in the direction of the support column 3 to release the lock on the sliding of the control block 5. When the control block 5 is moved to the adjustment area 37, the support rod 41 can slide to fit the ground under the action of the connecting rod 521, and the control column can continue to slide to the locking area 38. In this process, the drilling block 34 and the grounding column 411 can slide to embed into the ground, so that the bracket 2 is fixed on the ground. At this time, the control block 5 is not easy to slide toward the direction of the adjustment area 37 under the action of the locking block 39, and the installation of the bracket 2 is completed. If the soil at the installation location of the bracket 2 is relatively loose, water can be sprinkled at the installation point to compact the ground to improve the reliability of the bracket 2 fixed to the ground.

[0050] Then install the engineering projector 1 on the mounting platform 31, let the engineering projector 1 project rays at different angles, and then rotate the adjustment block 6 to control the engineering projector 1 to move to the range where the rays can enter the pile group without obstacles. The coordinates of the engineering projector 1 are detected by the measuring instrument, and the coordinates are input into the engineering projector 1 to position the engineering projector 1, and then the design coordinates and design elevation of the pile group are input into the engineering projector 1, so that the engineering projector 1 projects the corresponding rays, and the intersection of the engineering projectors 1 on both sides of the pile group is the design coordinates and design elevation of the mixing pile. After the construction of the mixing pile is completed, the above operation can be repeated to detect whether the pile position is offset.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
