Description

Technical Field

[0001] The invention belongs to the field of pipe pile construction devices, in particular to a prestressed pipe pile verticality rapid measurement device and a use method thereof. Background Art

[0002] Prestressed pipe pile driving usually adopts two construction techniques: hammering and static pressure. The hammering method often uses a pile hammer installed on a pile driving frame (pile driving limit frame) to integrate the prestressed pipe piles. The maximum pile driving depth depends on the effective height of the pile driving frame after the pile hammer is installed. During construction, the traditional method uses two theodolites to observe the vertical deviation and adjustment of the pile driving process at fixed points. The advantage of this method is accurate detection and adjustment, but the disadvantage is that the detection instrument adjustment time is long, which greatly reduces the efficiency of hammer pile driving. Another traditional method is to use a level ruler against the pile body of the pipe pile, and command the pile driver to adjust by observing the bubble position of the level tube. The advantage of this method is that it is easy to measure, but the disadvantage is that the error is large. Summary of the invention

Two groups of linkage rods 3-2 are symmetrically arranged. One end of each linkage rod 3-2 located at the lower end is fixedly connected to the guide column 3-1, and one end of each linkage rod 3-2 located at the upper end is rotatably connected to a slider, and is slidably connected to the guide column 3-1 through the slider.

[0029] A method for using a prestressed pipe pile verticality rapid measurement device, the method comprising the following steps:

[0030] S1: Place the device at the location where piling is required, and insert the positioning pins 1-2 into the soil to fix the device;

[0031] S2: Turn the screw rod 2-5 to adjust the verticality of the arc plate 2-4;

[0032] S3: Use a crane to lift the pipe pile 4 into the upper positioning ring 1-3, and energize the electric telescopic rod 2-2 to drive the two arc plates 2-4 to clamp and fix the pipe pile 4;

[0033] S4: Hammering the pipe pile 4.

[0034] The working principle of the present invention is:

[0035] When using the device, place the device in a well-dug pile hole, or at a location where piles need to be driven, insert the positioning pin 1-2 into the soil to fix the device, and use a crane to lift the pile 4 into the upper positioning ring 1-3 and place it between the two measuring devices 2. The device is connected to an external power supply, and the electric telescopic rod 2-2 is powered on and extended to drive the arc plate 1-4 to press against the outer wall of the pile 4. The pile 4 can be clamped and fixed by the two arc plates 1-4, and the verticality of the pile can be observed by the horizontal ruler set on the arc plate 1-4, and the screw 1-2-5 is turned in advance along the outer wall of the pile 4. The sliding of the slide groove can drive the arc plate 2-4 to rotate with the support plate 2-3 as the center, so as to adjust the angle of the arc plate 2-4. The arc plate 2-4 is adjusted to a vertical state according to the horizontal ruler. At this time, when the two arc plates 2-4 clamp the pipe pile 4, the pipe pile 4 can be automatically vertical and the pipe pile 4 can be limited. At this time, hammering the pipe pile 4 can drive the pipe pile into the soil. When the pipe pile 4 is moved by the hammer, it drives the measuring device 2 to slide downward along the slide rail 1-4, which plays a role of supporting and limiting the pipe pile 4, avoiding the pipe pile 4 from tilting when the pipe pile 4 is hammered. When the top of the pipe pile 4 moves When it reaches the docking device 3, it is necessary to dock another pipe pile 4. Use a crane to lift another pipe pile 4 to the upper end of the previous pipe pile 4 and press it against the top surface of the previous pipe pile 4. Press the linkage ring 3-4 downward to drive the linkage rod 3-2 to fold and drive the fixed block 3-3-1 to move inward through the slider. The fixed block 3-3-1 moves and drives the arc positioning plate 3-3-2 to press against the outer wall of the pipe pile 4 at the lower end. At the same time, turn the screw rod 2 3-3-7 to push the adjusting arc plate 3-3-4 to move and press against the outer wall of the pipe pile 4 at the upper end, and drive the adjusting arc through the screw rod 2 3-3-7. The arc plate 3-3-4 moves to adjust the docking accuracy of the two pipe piles 4 so that the two pipe piles 4 overlap perfectly. When the arc plate 3-3-4 moves, the spring 3-3-6 is compressed by the spring rod 3-3-5. The spring 3-3-6 plays the role of resetting the arc plate 3-3-4. At the same time, the top screw 3-6 is rotated to move along the top screw plate 3-5 and press against the pipe pile 4 at the upper end, which can prevent the pipe pile 4 from moving forward and backward when adjusting left and right, causing dislocation, thereby affecting the docking accuracy. After the docking is completed, the two pipe piles 4 can be welded. After the welding is completed, lift the linkage ring 3-4 upward to reset. After the current pipe pile 4 is driven in, control the electric telescopic rod 2-2 to shrink and reset the slide 2-1, and then fix the next pipe pile 4 through the above steps.

[0036] When piling is performed on an inclined surface, the device is fixed to the ground, and then the two screw rods 2-5 are respectively rotated to adjust the angles of the two arc plates 2-4 so that the two arc plates 2-4 are in a vertical state. Then, the pipe pile 4 is hoisted and clamped and limited by the two arc plates 2-4 to ensure the verticality of the pipe pile when operating on an inclined surface.
