Description

Technical Field

[0001] This application relates to the field of civil engineering pile foundation construction technology, and in particular to an auxiliary cement-soil mixing pile positioning device. Background Technology

[0002] In current cement-soil mixing pile construction, the project volume is large and the pile positions are dense. The positioning of the pile driver mainly relies on surveying instruments such as total stations in conjunction with manual marking, making the surveying and setting-out task heavy. Moreover, the traditional method has the following drawbacks: the pile driver needs to be re-measured and positioned after each pile position is completed, resulting in low construction efficiency; visual errors can easily occur during manual centering at night, greatly affecting the positioning accuracy; the pile position benchmark is easily disturbed in complex construction environments, causing pile position damage and requiring repeated restoration; and the surveying instruments need to be repeatedly started and stopped, increasing equipment wear and tear.

[0003] Therefore, it is imperative to develop a new type of auxiliary positioning device. Summary of the Invention

[0004] To solve or partially solve the problems existing in the related technologies, this application provides an auxiliary positioning device for cement-soil mixing pile machines.

[0007] Optionally, in some embodiments, the pile location marking mechanism 7 is formed by welding three steel bars of different sizes in pairs to form a "Y" shape.

[0008] The technical solution provided in this application may include the following beneficial effects: High positioning accuracy: By combining the "Y"-shaped pile positioning marker device with the double plumb bob positioning system, three-point collinear positioning is achieved, which effectively reduces human error and environmental interference, and significantly improves positioning accuracy; High construction efficiency: No surveyors are required to follow up throughout the process. Positioning can be completed quickly after the pile driver is moved, avoiding repeated layout and greatly shortening the construction cycle; Simple structure and low cost: Made of common building materials such as nuts, washers, precision rolled screws, and steel bars, the materials are easy to obtain and the manufacturing is simple, reducing equipment investment and labor costs; Wide range of applications: It can adapt to complex construction environments, avoid repeated restoration work caused by benchmark disturbance, reduce the wear and tear of measuring instruments, and has good economic benefits and practicality.

[0014] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0015] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0016] To address the aforementioned issues, this application provides an auxiliary positioning device for cement-soil mixing pile machines.

[0017] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0018] See Figure 1 , 3 4. The auxiliary cement-soil mixing pile positioning device includes: Positioning nut 1: Fixedly installed on the crossbeam 8 of the cement-soil mixing pile machine; First positioning scale 2: One end is threaded to the positioning nut 1, and the other end is fixed with the first positioning nut 3; Second positioning scale 4: One end is threaded to the first positioning nut 3, and the other end is fixed with the second positioning nut 5; Positioning plumb bobs 6: are respectively installed at the bottom of the first positioning nut 3 and the second positioning nut 5; Pile position positioning marker 7: Set at the center of the preset auxiliary positioning pile position, corresponding to the positioning plumb bob 6.

[0019] See Figure 2 To ensure the stability of the support of the positioning plumb bob 6 by the first positioning ruler 2 and the second positioning ruler 4, the positioning nut 1 is fixed on the cross beam 8 of the cement-soil mixing pile machine on the side away from the auxiliary positioning pile position 9, so that the first positioning ruler 2 passes through the cross beam 8 of the cement-soil mixing pile machine on the side close to the auxiliary positioning pile position 9, thus ensuring the stability of the support.

[0020] The positioning nut 1 includes a positioning nut washer 11 and a nut 12, which are coaxially fixedly connected.

[0021] The pile location marking mechanism 7 is formed by welding three steel bars of different sizes in pairs to form a "Y" shape.

[0022] Device connection steps: (1) Fabrication and installation of positioning nut 1: Weld the φ20mm nut 12 to the φ24mm positioning nut washer 11 with the center cut to form positioning nut 1; weld positioning nut 1 to the crossbeam 8 of cement soil mixing pile machine to ensure that the welding position matches the three-dimensional spatial position of the construction pile position and the auxiliary positioning pile position 9.

[0023] (2) Fabrication of scale assembly: A φ20mm precision rolled screw is used as the first positioning scale 2, and its threaded end is connected to the positioning nut 1; a φ16mm round steel is used as the second positioning scale 4, one end of which is threadedly connected to the first positioning nut 3 at the end of the first positioning scale 2, and the other end is welded with the second positioning nut 5 to form a complete scale assembly.

[0024] (3) Installation of positioning plumb bob 6: At the center of the first positioning nut 3 and the second positioning nut 5, a positioning plumb bob 6 with a specification of φ40mm, a total length of 80mm and a weight of 300g is suspended to form a double plumb bob positioning system.

[0025] (4) Installation of pile location marking device 7: Weld three steel bars of different sizes together to form a “Y” type pile location marking device 7, and fix it to the auxiliary positioning pile 9 on the ground after measurement and layout.

[0026] Work process: Step 1: After measurement and layout, fix the pile position positioning mark device 7 at the auxiliary positioning pile position 9 on the ground; Step 2: During the initial positioning of the pile driver, adjust the position of the pile driver according to the position of the pile positioning mark device 7 and the geometric relationship between the pile driver and the pile position to ensure that the installation reference of the positioning nut 1 is accurate. Step 3: Adjust the horizontal displacement of the pile driver using the pile positioning marker device 7 to bring the pile driver to the approximate positioning position; Step 4: Simultaneously observe the planar projection relationship between the two positioning plumb bobs 6 and the pile positioning mark device 7; Step 5: When the projections of the two positioning plumb bobs 6 are collinear with the center of the pile positioning mark device 7, the precise positioning of the pile driver is completed, and the mixing pile construction can be carried out. Step Six: After the construction of a single pile is completed and the pile driver is moved, the pile position positioning mark device 7 is moved synchronously. Steps Three to Five are repeated. By aligning the positioning plumb bob 6 with the pile position positioning mark device 7, the positioning of the next pile can be quickly completed without the need for surveyors to redo the layout.

[0027] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
