Description

Technical Field

[0001] The present application relates to the technical field of roadbed protection engineering construction, and in particular to a laser controller for the verticality of bored piles. Background Art

[0002] Highway construction often passes through mountainous areas with complex geology. Affected by the geological topography, there are many landslides. Anti-slide piles are an important basic engineering facility to improve soil stability and prevent structural slippage.

[0003] Since anti-slide pile designs are mostly located in areas with complex geological conditions, large machinery cannot enter the site for operation, and the use of manual digging construction technology remains an irreplaceable construction technology.

[0004] The traditional construction process of bored piles is: first, the four corner points of the anti-slip pile are laid out, excavation is carried out according to the laid out corner points, and then the first section of the retaining wall and the lock are cast. When excavating the second section of the pile body, it is often done by first excavating in the general direction, and then using a plumb bob to hang the second section of the retaining wall, and so on. This operation is time-consuming and labor-intensive, and has large errors. Utility Model Content

[0005] To this end, the present application provides a laser controller for the verticality of bored piles to solve the problem that the operation using a plumb bob is time-consuming, labor-intensive and has large errors.

[0026] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0027] In the description of this application: unless otherwise specified, the meaning of "plurality" is two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0028] The terms such as "upper", "lower", "left", "right", "middle", etc. cited in this application are usually used to indicate the general relative position relationship for the purpose of intuitive understanding by referring to the drawings, and are not absolute limitations on the position relationship in the actual product.

[0029] A laser controller for verticality of bored piles, used to control the verticality of the pile body and the size of the retaining wall of the bored piles (square anti-slip piles). Figure 1 , including a rectangular main frame, the main frame includes a plurality of horizontally arranged transverse tubes and a plurality of longitudinally arranged longitudinal tubes connected to each other, and the horizontal tubes and the longitudinal tubes are both made of square tubes. Among them, the main frame is made of alloy material. Among them, the top and bottom of the main frame are both opened, so that the operator can enter the main frame for operation.

[0030] A total of four strip laser emission sources are arranged on the main frame, and the four strip laser emission sources are arranged on the four sides of the main frame respectively, and are installed on the inner sides of the corresponding transverse tubes and longitudinal tubes respectively. Correspondingly, a mounting hole is arranged on one of the longitudinal tubes or transverse tubes of the main frame, and a switch and a battery box are arranged in the mounting hole.

[0031] The switch is installed on the surface of the horizontal tube or the vertical tube to control the opening and closing of the strip laser emission source. To prevent accidental touch of the switch, in other embodiments, a protective cover can be set on the main frame to isolate the switch from the external environment.

[0032] The battery box is installed in the horizontal tube or the vertical tube in an embedded manner to supply power to the four strip laser emission sources. In other embodiments, in order to facilitate battery replacement, the cover of the battery box is configured as a detachable structure that is hinged or clamped.

[0033] Furthermore, the strip laser emission source is set as a retractable structure and is hingedly mounted on the inner side of the main frame so that it can rotate freely. Therefore, when the instrument is used, the position, direction and telescopic length of the strip laser emission source can be adjusted according to the thickness of the protective wall.

[0034] In addition, in order to protect the strip laser emission source, a slot for accommodating the strip laser emission source is opened on the inner side of the main frame, so that the strip laser emission source can be retracted into the slot when the instrument is not in use.

[0035] In order to facilitate installation and use, a base for supporting the main frame is welded to the bottom of the main frame. A circular level tube is set at the top of each side of the main frame, and the upper end surface of the level tube is flush with the upper end surface of the main frame. On this basis, the base is set as an adjustable spiral structure. The height of the main frame can be adjusted to a suitable position through the screws set on each base, and the main frame can be easily adjusted to a horizontal position in combination with the level tube.

[0036] Furthermore, the main frame is configured as a retractable structure. Specifically, a retractable section is provided on each side of the main frame, and the retractable section is provided at a position close to the center of each side. During installation, four retractable sections are provided between any two horizontal tubes or any two vertical tubes on each side of the main frame. By adjusting the length of the retractable section, the overall length and width of the main frame can be adjusted to be suitable for pile foundation drilling work of different sizes.

[0037] The implementation principle of the embodiment of the present application is: adjust the size of the alloy composite main body frame according to the size of the design drawing to meet the design size requirements. After adjusting the size, place the verticality laser controller of the manually excavated pile (square anti-slip pile) on the pile foundation lock, and adjust the instrument to the level by adjusting the adjustable spiral base and combining the level bubble of the level tube. After the instrument is installed, adjust the position and telescopic length of the strip laser emission source according to the thickness of the retaining wall, turn on the switch, and the strip laser emission source starts to work, releasing the strip light curtain from the four sides of the pile foundation. The operator sets up the retaining wall template according to the position of the light curtain and combines the design drawings, pours the retaining wall concrete, and repeats this operation until the pile foundation is bored.

[0038] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
