Description

Technical Field

[0001] This invention relates to the field of building construction technology, and more specifically, to a pile position control device. Background Technology

[0002] Composite piles are a new type of economical and effective pile that is very suitable for the treatment of soft soil foundations in coastal areas. They combine the advantages of two or three unit pile types and can be combined in various ways in a targeted and flexible manner according to soil conditions, superstructure requirements, and reinforcement purposes. The pile diameter, pile length, lime content, strength, gradation, mixing and number of blows of various piles can be adjusted to make the composite pile fully utilize the skin friction of the soft soil around the pile and the bottom resistance of the pile, and match the material strength to generate a sufficiently high single pile bearing capacity. It can also significantly improve the strength of the soil between the piles and its participation in the bearing capacity, so as to meet different design requirements.

[0003] Flexible-rigid composite piles refer to piles that combine flexible and rigid piles. During the construction of cement-soil-prestressed pipe pile composite piles, poor control of the verticality of the later-constructed prestressed pipe piles often results in the pile's verticality or coaxiality exceeding the allowable range specified in the standards. This not only poses a threat to the pile foundation's bearing capacity but can also lead to the pile failing to reach the designed length, resulting in the pile becoming unusable and severely impacting construction progress and structural safety. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose a pile position control device, which can adjust the verticality and coaxiality of the pile, thereby improving the stability of composite pile installation and ensuring construction progress.

[0006] The pile position control device of the present invention includes:

[0007] A support assembly includes a support column located on one side of the pile body and extending vertically; a correction and adjustment assembly includes a telescopic component and an adjustment component. The telescopic component is connected to the support column and is used to drive the support column to move radially along the pile body. The adjustment component consists of at least two components spaced apart vertically along the support column. The adjustment component is adapted to cooperate with the pile body and is horizontally adjustable.

[0008] According to an embodiment of the present invention, when the verticality of the pile body deviates, the dimensions of the two upper and lower adjustable components can be changed to adjust the verticality of the pile body to within the allowable range. When the coaxiality of the pile body deviates, the support column can be moved by the telescopic component, thereby causing the two adjustable components to move as a whole, pushing the axis of the pile body to largely coincide with the axis of the pile hole, thus ensuring the coaxiality of the inner core pile body and the outer core pile body. Therefore, the pile body position control device of the present invention can adjust the verticality and coaxiality of the pile body, ensuring the bearing capacity and stability of the pile foundation, and avoiding the situation where the pile body cannot be driven to the designed length, thus ensuring the construction progress and structural safety.

[0009] In some embodiments, there are multiple support columns, which are arranged at intervals along the circumference of the pile body. There are multiple correction and adjustment components, which correspond one-to-one with the multiple support columns, and the adjustment components abut against the pile body.

[0010] In some embodiments, the telescopic component includes a jack and a reaction block. The reaction block is installed on the side of the support column away from the pile body, and the lower end of the reaction block is in contact with the ground. One end of the jack is connected to the reaction block, and the other end of the jack is connected to the support column.

[0011] In some embodiments, the adjusting component includes an adjusting section and a force transmission section, the adjusting section being connected to the support column via the force transmission section, and the length of the adjusting section along the radial direction of the pile body being adjustable.

[0012] In some embodiments, the force transmission section is detachably and replaceably connected to the adjustment section and the support column.

[0013] In some embodiments, the adjusting section has an elastic contact portion at one end adjacent to the pile body, the elastic contact portion being elastically deformable along the radial direction of the pile body.

[0014] In some embodiments, the pile position control device further includes a displacement gauge, the displacement gauge having an adjustable radial dimension along the pile body, the displacement gauge being disposed at one end of the adjusting member adjacent to the pile body and abutting against the pile body.

[0015] In some embodiments, the support assembly further includes a support base plate, which is annular, and the support columns are disposed on the upper end surface of the support base plate, with a plurality of support columns arranged at intervals along the circumference of the support base plate.

[0016] In some embodiments, the support assembly further includes a column hoop, which is disposed above the support base plate and is annular and connected to a plurality of support columns.

[0017] In some embodiments, the support column is provided with a through hole, and the column hoop is a flat steel piece, which passes through the through hole. Attached Figure Description

[0025] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] The following is a reference appendix. Figure 1 and Figure 2 A pile position control device according to an embodiment of the present invention is described.

[0027] like Figures 1 to 2 As shown, the pile position control device according to an embodiment of the present invention includes: a support assembly 1 and a correction adjustment assembly 2. The support assembly 1 includes a support column 11, which is disposed on one side of the pile body 4 and extends in the vertical direction. The correction adjustment assembly 2 includes a telescopic component 21 and an adjustment component 22. The telescopic component 21 is connected to the support column 11 and is used to drive the support column 11 to move radially along the pile body 4. There are at least two adjustment components 22, which are spaced apart in the vertical direction of the support column 11. The adjustment components 22 are adapted to cooperate with the pile body 4 and their dimensions are adjustable in the radial direction of the pile body 4.

[0028] According to an embodiment of the present invention, when the verticality of the pile body 4 deviates, the dimensions of the two upper and lower adjustable components 22 can be changed to adjust the verticality of the pile body 4 to the range allowed by the specification. When the coaxiality of the pile body 4 deviates, the support column 11 can be moved by the telescopic component 21 to drive the two adjustable components 22 to move as a whole, so as to push the axis of the pile body 4 to largely coincide with the axis of the pile hole, thereby ensuring the coaxiality of the inner core pile body 4 and the outer core pile body.

[0029] Therefore, the pile position control device of the present invention can adjust the verticality and coaxiality of the pile body 4, ensuring the bearing capacity and stability of the pile foundation, and can avoid the situation where the pile position is abandoned because the pile body 4 cannot be driven into the designed length, thus ensuring the construction progress and structural safety.

[0030] In some embodiments, there are multiple support columns 11, which are arranged at intervals along the circumference of the pile body 4. There are also multiple correction adjustment components 2, each corresponding to one of the support columns 11, with the adjustment components 22 abutting against the pile body 4. It is understood that there can be two or more support columns 11; for example, there can be two, three, or four support columns 11. Correspondingly, the number of correction adjustment components 2 is the same as the number of support columns 11.

[0031] In the embodiments of this application, there are four support columns 11 and four correction adjustment components 2. The four support columns 11 are arranged at equal intervals along the circumference of the pile body 4, and the four correction adjustment components 2 correspond one-to-one with the four support columns 11, so that the angle and position of the pile body 4 in the four directions of front, back, left and right can be adjusted until the verticality and coaxiality of the pile body 4 are controlled and adjusted to the range allowed by the specifications.

[0032] In some embodiments, the telescopic component 21 includes a jack 211 and a reaction block 212. The reaction block 212 is installed on the side of the support column 11 away from the pile body 4, and its lower end is in contact with the ground. One end of the jack 211 is connected to the reaction block 212, and the other end of the jack 211 is connected to the support column 11. It is understood that the jack 211 is adjustable in the horizontal direction. When the jack 211 extends or retracts, the reaction block 212 remains stationary. Therefore, the jack 211 can drive the support column 11 to move as a whole toward or away from the pile body 4. Because the jack 211 can apply a larger load to the support column 11, it can improve the reliability of the pile position control device compared to motor drive.

[0033] In some embodiments, the adjusting component 22 includes an adjusting section 221 and a force transmission section 222. The adjusting section 221 is connected to the support column 11 via the force transmission section 222, and the length of the adjusting section 221 along the radial direction of the pile body 4 is adjustable. It is understood that the force transmission section 222 extends radially along the pile body 4 to fix the adjusting section 221 to the side of the support column 11 adjacent to the pile body 4. Because the length of the adjusting section 221 along the radial direction of the pile body 4 is adjustable, the upper or lower adjusting section 221 of the correction adjusting component 2 can be adjusted to adjust the verticality of the pile body 4 to within the range allowed by specifications.

[0034] For example, the adjusting section 221 can be a threaded drive pair, meaning that the length of the adjusting section 221 is adjusted by the extension and retraction of a screw. Alternatively, the adjusting section 221 can be a small hydraulic cylinder, pneumatic cylinder, or oil cylinder, etc., to adjust the length of the device itself.

[0035] For example, the adjustment section 221 is a detachable H-beam, and the verticality of different pile bodies 4 can be adjusted by replacing the adjustment section 221 with different lengths.

[0036] In some embodiments, such as Figures 1 to 2 As shown, the force transmission section 222 is detachably and replaceably connected to the adjustment section 221 and the support column 11. For example, the force transmission section 222 is an H-beam, and it is detachably connected to the adjustment section 221 and the support column 11 via threaded connections. Because the force transmission section 222 is detachably and replaceably connected to the adjustment section 221 and the support column 11, the pile body 4 position control device can meet the adjustment requirements of different composite piles, thus expanding its application range.

[0037] Optionally, the adjusting section 221 has an elastic contact portion (not shown) at one end adjacent to the pile body 4, which is elastically deformable along the radial direction of the pile body 4. For example, the elastic contact portion can be a spring. Since the spring can undergo elastic deformation within a certain range, the adjusting section 221 can be adjusted to pile bodies 4 of different diameters. In other words, for pile bodies 4 of different diameters, the elastic contact portion can always abut against the pile body 4, thereby improving the applicability of the pile body 4 position control device.

[0038] In some embodiments, the pile position control device further includes a displacement gauge 3, the displacement gauge 3 having an adjustable radial dimension along the pile body 4, and the displacement gauge 3 being disposed at one end of the adjusting member 22 adjacent to and abutting against the pile body 4. The displacement gauge 3 can detect the verticality and inclination of the pile body 4. Since the displacement gauge 3 has an adjustable radial dimension along the pile body 4, the displacement of the pile body 4 is monitored at the start of pile driving, and when the displacement reaches the upper limit of the allowable value, the coaxiality or verticality adjustment begins.

[0039] Understandably, each of the upper and lower adjustment components 22 of the correction adjustment assembly 2 is equipped with a displacement gauge 3. In other words, when the displacement gauge 3 on the upper side of the adjacent support column 11 reaches the upper limit of the allowable value, the verticality of the pile body 4 needs to be adjusted. When both the displacement gauge 3 on the upper side of the adjacent support column 11 and the displacement gauge 3 on the lower side of the adjacent support column 11 reach the upper limit of the allowable value, coaxiality adjustment needs to be performed.

[0040] In some embodiments, such as Figure 1 As shown, the support assembly 1 also includes a support base plate 12, which is annular. Support columns 11 are disposed on the upper surface of the support base plate 12, and multiple support columns 11 are arranged at intervals along the circumference of the support base plate 12. It can be understood that since the lower ends of the support columns 11 are in contact with the support base plate 12, the support base plate 12 can support the support columns 11, avoiding the problem of unstable installation of the support columns 11 due to uneven ground.

[0041] Optionally, such as Figure 2 As shown, the support assembly 1 also includes a column hoop 13, which is located above the support base plate 12. The column hoop 13 is annular and connected to multiple support columns 11. For example, the support columns 11 have through holes, and the column hoop 13 is a flat steel piece that passes through the through holes. It can be understood that the column hoop 13 can connect multiple support columns 11 together, thereby making the structure of the pile position control device more stable.
