Description
Technical Field
The invention relates to a method for making a pile body vertical, in particular to a method for controlling the verticality of a cement mixing pile body.
Background
The perpendicularity of a pile body needs to be strictly controlled in the construction of pile foundation engineering. Use the straightness that hangs down of theodolite monitoring pile body in traditional construction, but the theodolite easily receives the influence of wind-blowing, hammer pile driving in-process vibrations, causes the error to survey, control pile body straightness that hangs down, and the quality problems appears, when serious, can cause the pile body rupture. In the method for hanging the plumb, the vertical state of the plumb can be influenced by wind power, the self vibration of machinery in the piling process and the like, and the true vertical state of a pile body cannot be ensured; and the plumb bob is hung at the drill rod frame and is far away from the operating platform of a worker, so that a certain error exists when an operator distinguishes verticality.
Chinese patent CN208282757U discloses in 2019, 3.1.2019 a pile body verticality monitoring device, which comprises a chassis, two telescopic columns, and a cross rod with a scale, and further comprises a lifting ring, a windshield, a plumb bob and a plumb bob suspension wire, wherein the telescopic columns are vertically arranged on the chassis, the cross rod is connected with the two telescopic columns, the lifting ring is arranged in the center of the cross rod, the windshield is arranged on the chassis, one end of the plumb bob suspension wire is wound on the lifting ring, the other end of the plumb bob suspension wire is connected with the plumb bob, and the plumb bob is suspended in the windshield. This device still belongs to the plumb method, and its precision has the limitation.
Chinese patent CN1130167A discloses a device and a method for quickly and accurately measuring the perpendicularity of a bored pile body in 2014 9 months, which includes a centering connection plate, four measuring scales fixed on the centering connection plate respectively and having scale values, wherein the central lines of the two measuring scales are located on the same straight line and are in the same direction as the transverse radial direction of the steel casing, the central lines of the other two measuring scales are located on the same straight line and are in the same direction as the longitudinal radial direction of the steel casing, and the two measuring scales located on the transverse radial direction of the steel casing are perpendicular to the two measuring scales on the longitudinal radial direction.

Detailed Description
The present invention will be further described with reference to the following examples and the accompanying drawings.
Example 1
Leveling air bubbles are widely used in leveling equipment, as is well known. The leveling bubble levels mechanical equipment by utilizing the principles of liquid flow and liquid level, and the method replaces the traditional plumb hanging method to correct the verticality of the pile body; the main principle is that the leveling bubble is fixed on a cross beam of a body of the powder-spraying pile machine and is close to an operation table (easy to observe by a mechanical operator), and when the mechanical pile is driven, the height of four leg legs of the pile machine is adjusted through hydraulic pressure, so that the level of the leveling bubble is adjusted, the body is horizontal, and a rotating rod of the pile machine is perpendicular to the ground when the pile machine is operated.
Because the powder injection type pile machine is limited by self design, the pile machine is not provided with a leveling device, and the vertical construction of the pile body is difficult to ensure by the pile machine operator in the construction process, so that the pile body of the composite foundation is deflected and the requirement of the designed bearing capacity is more likely to be not met; and the density of the pile body of the cement mortar pile composite foundation is larger, so that the pile body is ensured to be vertical (not deviated), and the requirement of the bearing capacity of the foundation can be better met. The traditional pile machine is controlled by hanging a plumb bob to control the verticality of a pile body, and the method is economical and convenient, but is influenced by external natural environment (such as wind and the like and self vibration of machinery), so that the verticality of the pile body cannot be guaranteed;
referring to fig. 1, fig. 1 is a schematic view illustrating an arrangement position of a three-level bubble level according to an embodiment of the present invention. As shown, the leveling bubble level is a commercially available product with a diameter of 60 x 10mm and an accuracy of 6 min/2 mm. The level bubble level gauge is convenient to install and use. The three-level bubble level gauge provided by the embodiment of the invention is characterized in that a level bubble is arranged on a pile machine operation platform, two level bubbles are arranged on a pile machine frame body, and the three level bubbles are used for adjusting the verticality of a pile machine and the pile machine frame body, so that the verticality of a pile body of a pile is ensured. The pile driver can be adjusted by the pile driver before operation, so that more accurate perpendicularity is achieved, and the traditional method for hanging the plumb bob is replaced.
FIG. 2 is a schematic plan view of a leveling bubble level according to an embodiment of the present invention, which employs a leveling large bubble that can be mounted on a horizontal beam of a pile driver body and is located closer to a manipulator for viewing. The bubbles should be checked parallel to the mechanical cross beam before installation.
Because the rotating rod is perpendicular to the cross beam of the body, the mechanical operator can ensure that the cross beam of the body is horizontal (i.e. the rotating rod is perpendicular to the ground) by hydraulically lifting or lowering the height of the four legs during the piling process. Meanwhile, whether the mechanical beam is horizontal or not is judged by observing the centering of the air bubble in the leveling air bubble (the principle is the same as that of the leveling instrument).
The method for controlling the verticality of the pile body of the cement mixing pile has substantive characteristics and obvious technical progress, and is influenced by natural environment (such as self vibration of a wind power action machine and the like) and human factors based on the traditional plumb bob hanging method, so that the accurate verticality of a front rotating rod of the pile driver during operation is difficult to be really ensured. The influence of the external natural environment can be overcome by utilizing the level bubble, the verticality of the pile head and the rotating rod before the piling operation is ensured more accurately, and the engineering quality is better ensured. When the leveling bubble is positioned at the center of the bubble dial, the horizontal beam of the pile machine is horizontal at the moment, namely the rotating rod of the pile machine is vertical to the ground. The condition meets the vertical construction requirement of the pile body, and the piling operation can be started.
The above embodiments are provided only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Accordingly, all equivalents are intended to fall within the scope of the invention, which is defined in the claims.
