DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figures 1 to 5 As shown, the present invention discloses a pipe pile construction measurement method, which is applicable to the measurement work in the concrete pipe pile construction process and the acceptance process, and is particularly applicable to the construction measurement of pile groups. Specifically, the method comprises the following steps:

[0038] Step S1, according to the cross-sectional size of the pipe pile 1, a clamp device is made, the clamp device includes a pipe pile clamp 3, a circular angle gauge 7, a T-shaped slider 2 and a measuring instrument fixture; the circular angle gauge 7 is fixed on the top of the pipe pile clamp 3, and the side wall of the pipe pile clamp 3 is provided with two T-shaped slide grooves 5 (double-layer structure design) at intervals above and below, and each T-shaped slide groove 5 is arranged in a circular ring shape along the outer circumference of the pipe pile clamp 3, each T-shaped slide groove 5 can be slidably connected with a T-shaped slider 2, and each T-shaped slider 2 can slide freely 360° in the T-shaped slide groove 5 where it is located; the outer side of each T-shaped slider 2 is fixedly connected with a measuring instrument fixture by bolts; the measuring instrument fixture includes two L-shaped structural plates 8 arranged opposite to each other, the bottom plates of the two L-shaped structural plates 8 are comb-shaped, and the bottom plates of the two L-shaped structural plates 8 are provided with strip holes 81; the two L-shaped structural plates The bottom plates of the two L-shaped structural plates 8 cooperate with each other and are plugged together (that is, the comb teeth on the bottom plates of the two L-shaped structural plates 8 are relatively staggered. Specifically, the bottom plate of one L-shaped structural plate 8 includes three comb tooth plates arranged at intervals, and the bottom plate of the other L-shaped structural plate 8 includes two comb tooth plates arranged at intervals, and the two comb tooth plates of the L-shaped structural plate 8 can be plugged into the intervals between the three comb tooth plates to form the bottom plate of the measuring instrument fixture). The comb tooth plates of the two L-shaped structural plates 8 are respectively provided with strip holes 81, and two sliding bolts 10 pass through the strip holes 81 of each comb tooth plate and are arranged on the bottom plate of the measuring instrument fixture, so that the two L-shaped structural plates 8 can be connected together in an openable and closable manner through the two sliding bolts 10, that is, the sliding bolts 10 are driven to move in the strip holes 81 by the two L-shaped structural plates 8 to realize the width adjustment of the measuring instrument fixture, thereby improving the applicability to fixtures of different sizes. The inner sides of the side plates of the two L-shaped structural plates 8 are provided with sawtooth blocks 12 to facilitate clamping of the measuring instrument 9 located between the two L-shaped structure side plates. The sawtooth blocks 12 are made of flexible material to protect the measuring instrument 9 while clamping and fixing. A connecting block is fixed on both sides of the two L-shaped structural plates 8, and a clamping bolt 11 is connected between the two connecting blocks to achieve clamping of the L-shaped structural plates 8 on both sides through the clamping bolts 11, thereby clamping the measuring instrument 9 placed between the sawtooth blocks 12 on both sides, thereby firmly fixing the measuring instrument 9.

[0039] Specifically, the above-mentioned pipe pile clamp 3 includes two semicircular clamps, and a clamp connecting plate 4 is provided on both sides of the two semicircular clamps. The clamp connecting plates 4 arranged opposite to each other of the two semicircular clamps are fixed together by connecting bolts to facilitate the fixing of the pipe pile clamp 3 on the pipe pile 1 or removal from the pipe pile 1. The contact surface between the above-mentioned T-shaped slider 2 and the T-shaped slide groove 5 is provided with lubricating grease to ensure that the T-shaped slider 2 can slide freely 360° in the plane (that is, the T-shaped slider 2 can slide freely 360° in the T-shaped slide groove 5).

[0040] The circular angle gauge 7 is composed of two parts (i.e. two semicircular angle gauges 7), which are fixed together with the tops of the two semicircular clamps respectively. The circular angle gauge 7 can display the rotation angle when the T-shaped slider 2 moves and rotates at any angle, which is used for auxiliary measurement of the construction measurement of the pipe pile 1.

[0041] In an embodiment of the present invention, the material of the clamp device is aluminum alloy, and the various components of the clamp device are manufactured by machining. Specifically, the pile clamp 3, T-shaped slide groove 5, T-shaped slider 2 and measuring instrument clamp are all manufactured by machining, thereby ensuring the machining accuracy, and further ensuring the installation accuracy and measurement accuracy.

[0042] Step S2, fixing the clamp device on the qualified pipe pile 1, that is, the pipe pile clamp 3 is tightly connected with the qualified concrete pipe pile 1.

[0043] Before the step of fixing the clamp device on the qualified pipe pile 1, the step of installing an elastic rubber pad 6 on the contact surface between the pipe pile clamp 3 and the pipe pile 1 is also included. The elastic rubber pad 6 has good shock absorption performance and large damping characteristics, which can ensure that the pipe pile clamp 3 is firmly installed on the concrete pipe pile 1. The elasticity of the rubber pad can offset the manufacturing deviation of the pipe pile 1 and the clamp device.

[0044] Step S3, installing the measuring instrument 9 on the measuring instrument fixture, and using the measuring instrument 9 to measure the pipe pile construction; wherein the measuring instrument 9 includes an infrared transmitter and a laser rangefinder, and the pipe pile construction measurement includes the measurement of the straightness of the pile row, the pile spacing, the pipe pile diagonal, and the pile top elevation. The measuring instrument 9 is used to measure the pipe pile construction, mainly using a clamp device, supplemented by an infrared transmitter, a laser collimator, a square ruler and other measuring tools, so as to achieve rapid and accurate measurement of the pipe pile.

[0045] Specifically, Figure 6As shown, when measuring the straightness of the pile row, the clamp device is fixed on the first angle pile that has passed the acceptance inspection; after installing the infrared transmitter on the measuring instrument fixture, the position of the infrared transmitter on the pipe pile 1 is adjusted by the T-shaped slider 2, and it can be kept horizontal, and the straightness deviation of the pile row is measured with a square ruler. Specifically, after the position is adjusted, the angle of the circular angle gauge 7 is recorded, and the visible infrared ray is used to replace the traditional "wire pulling" for measurement, and in the subsequent pile foundation construction, the square ruler is used to quickly and accurately measure the straightness deviation of the pile position. After the construction of the pile row is completed, the T-shaped slider 2 is rotated 90° counterclockwise to measure the straightness deviation of the "pipe pile matrix" in another direction. Of course, in the embodiment of the present invention, infrared transmitters can also be installed on both the upper and lower measuring instrument fixtures, and then two infrared transmitters are used to measure the straightness in two directions at the same time (that is, infrared transmitters are installed on the clamps of the upper and lower layers to complete the measurement of the straightness in two directions at the same time).

[0046] like Figure 7 As shown, when measuring the distance between piles, after installing the laser rangefinder on the measuring instrument fixture, the position of the laser rangefinder on the pipe pile 1 is adjusted by the T-shaped slider 2, and it is kept horizontal. At the same time, the angle of the circular angle gauge 7 is adjusted to zero (coinciding with the reference angle), and the distance between the pipe pile and the adjacent pipe pile is measured by the laser rangefinder. Specifically, by rotating the T-shaped slider 2 to 0° (assuming the reference is 0°), 90°, 180°. When the 360° direction is used, the deviation of the adjacent pile position can be quickly measured according to the degree of the laser rangefinder. Of course, in the embodiment of the present invention, laser rangefinders can also be installed on both the upper and lower clamps to measure the distance between piles in two directions at the same time.

[0047] like Figure 8 As shown, when measuring the diagonal of the pipe pile, after installing the laser rangefinder on the measuring instrument fixture, the position of the laser rangefinder on the pipe pile 1 is adjusted by the T-shaped slider 2 to keep it horizontal, and at the same time adjusted to the designed diagonal angle. According to the degree of the laser rangefinder, the degree of the diagonal of the pipe pile matrix can be quickly measured, and then the diagonal deviation can be obtained; of course, in the embodiment of the present invention, the laser rangefinder can also be installed on the upper and lower clamps to simultaneously complete the measurement of the diagonal of the pipe pile matrix in two directions.

[0048] Of course, in the embodiments of the present invention, laser rangefinders can be installed on the upper and lower clamps to simultaneously measure the pile spacing and the pipe pile diagonal, or laser rangefinders and infrared transmitters can be installed on the upper and lower clamps respectively to simultaneously measure the pile straightness and the pile spacing / pipe pile diagonal. The specific measurement can be flexibly changed according to the measurement needs of pipe pile construction.

[0049] In addition, according to the different types of measuring instruments 9, construction measurements of different projects can also be achieved. For example, by using an "infrared transmitter" in combination with a "tower ruler", the distance from the marking line to the pile top can be measured using a tower ruler according to the position of the infrared ray, and the deviation value of the "pile top elevation" can be measured.

[0050] Specifically, for example, a photovoltaic composite power generation project from one place to another is designed with a total of 100,000 meters of pipe piles 1, which are divided into 16 photovoltaic matrices. During the construction of the pipe piles 1, the present invention is adopted, which greatly improves the measurement construction efficiency, ensures the measurement accuracy, and then ensures the construction quality, achieving the expected effect.
