Embodiment 1

[0022] Embodiment one: if figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 and Figure 7 As shown, a cement fly ash gravel pile verticality control device includes a fixed plate 1, the middle part of one side of the fixed plate 1 is fixed with a connecting rod 2, and the connecting rod 2 is provided with a device to fix the device on the handrail of the pile driver The locking mechanism 3 on the top, the other side of the fixed plate 1 is embedded with a whiteboard 4, the middle part of the top of one side of the whiteboard 4 is fixed with a fixed block 5, and one side of the fixed block 5 is provided with a winding drum 6, and the winding drum The middle part on one side of 6 is fixedly provided with inserting rod 7, and one end fixed block 5 of inserting rod 7 is inserted and connected, and the middle part on one side of fixed block 5 is interspersed with locator 8, and one end of locating member 8 passes through inserting rod 7 and is connected with ...

Embodiment 2

[0028] Embodiment two: if Figure 8 As shown, a cement fly ash gravel pile verticality control device includes a wooden box 16, one side of the wooden box 16 is open, and the middle part of the top of the wooden box 16 is fixed with a second thin line 17, the second The bottom of two thin lines 17 is fixedly provided with the second plumb 18, and the middle part of wooden box 16 inner side is provided with the second two-way scale mark 19.

[0029] Applying the verticality control device of the above-mentioned embodiment 2 to a construction method for controlling the verticality of cement fly ash gravel piles includes the following steps: Step 1. Production of the wooden box 16: the wooden box 16 should be square and processed with wooden formwork At the same time, strictly control the squareness of the wooden box 16, cut it into one piece of 1.1m×0.2m, two pieces of 1.1m×0.1m wooden board, and two pieces of 0.1m×0.2m wooden board, and use iron nails to make it into a cuboid w...

Embodiment 3

[0034] Embodiment three, a construction method for verticality control of cement fly ash macadam pile, comprising:

[0035] Step 1: First, use two total stations or theodolite to adjust the pile driver to a vertical state; Step 2: Fix two verticality control devices on the pile driver body, install them in two vertical directions, and control its lateral direction Perpendicular to the longitudinal direction, the observation readings are more intuitive, and the verticality control device and the pile driver are fixed firmly; Step 3: When the installation is completed and used, adjust the first line of the verticality control device to a stable state by hand, and it is not allowed to appear In the case of a large swing, observe the deviation between the first two-way scale line 15 of the verticality control device and the first thin line 10, and readjust the leveling of the pile foundation if the requirements are not met. Calculate the scale of the allowable deviation of the thi...

Abstract

The invention discloses a cement fly ash gravel pile perpendicularity control device and a construction method. The cement fly ash gravel pile perpendicularity control device comprises a fixing plate, wherein a connecting rod is fixedly arranged in the middle of one side of the fixing plate, locking mechanisms for fixing the device on a pile machine handrail is arranged on the connecting rod, a blank board is embedded in the other side of the fixing plate, a fixing block is fixedly arranged in the middle of the top end of one side of the blank board, a winding drum is arranged on one side of the fixing block, an inserting rod is fixedly arranged in the middle of one side of the winding drum, one end of the inserting rod is connected with the fixing block in a penetrating mode, and a positioning piece is inserted in the middle of one side of the fixing block. According to the cement fly ash gravel pile perpendicularity control device, the precision is high, the vertical deviation of the pile body in the two directions is controlled within a certain range through the gravity action of a second plumb, observation is convenient, data can be directly read within 20 meters away from a pile machine, a pile machine driver can conveniently observe the perpendicularity deviation of the pile machine in a cab, and adjustment is convenient.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to a verticality control device and a construction method of a cement fly ash gravel pile. Background technique [0002] Cement fly ash gravel piles are suitable for handling foundations such as cohesive soil, silt soil, sandy soil and plain fill soil that has been consolidated by self-weight. For muddy soil, its applicability should be determined according to regional experience or field tests. As far as the foundation form is concerned, it can be used not only for extended foundations, but also for box foundations and raft foundations. At present, in the construction process of cement fly ash gravel piles, due to various factors, the verticality of the pile body cannot be controlled, and the verticality of the pile body directly affects the bearing capacity of the rechecked foundation. Therefore, we improve this and propose a verticality control device and construc...
