Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated sheet pile planting construction, and in particular to a prefabricated sheet pile planting construction method. Background Art

[0002] During the construction of the basement, precast sheet piles need to be connected to precast beams through connectors. Usually, nuts are embedded in the side walls of the precast sheet piles, and nuts are also reserved on the end faces of the precast beams. Therefore, the error in the installation of the precast sheet piles during construction must not be too large, so as to ensure that the screw holes of the precast sheet piles can be accurately connected to the screw holes of the precast beams.

[0003] However, the existing determination of the construction position of precast sheet piles cannot meet the design requirements. In order to achieve accurate connection between precast sheet piles and precast beams, the construction error of precast sheet piles needs to be further reduced. Summary of the Invention

[0004] In order to solve the technical problems of existing prefabricated sheet piles, the present invention provides a prefabricated sheet pile planting construction method.

[0005] To achieve the purpose of the present invention, the present invention adopts the following technical solutions:

[0006] A prefabricated sheet pile planting construction method, characterized by comprising a step of establishing a monitoring and control grid and a subsequent step of planting the prefabricated sheet piles, wherein the step of establishing the monitoring and control grid comprises:

[0007] Preliminary establishment of a monitoring and control grid: Surveying and mapping instruments are set up at multiple predetermined locations according to the construction design requirements to preliminarily establish a monitoring and control grid through surveying and mapping instruments;

[0008] Correction of the monitoring and control grid: Measure the error of the initially established monitoring and control grid with measuring instruments, and adjust the surveying and mapping instruments according to the error range required by the construction so that the precast sheet pile construction positions formed by the monitoring and control grid meet the design requirements.

[0009] Furthermore, in the initial steps of establishing the monitoring and control grid, the corner point positions are first determined based on the construction site, and corner point surveying instruments are set at the corner point positions; then, at least one intermediate surveying instrument is set on the surveying line of the adjacent corner point surveying instrument according to the construction design requirements; the surveying lines of the corner point surveying instrument and the intermediate surveying instrument intersect to form a monitoring and control grid.

[0010] Furthermore, in the initial establishment step of the monitoring and control grid, the error accuracy of the initially established monitoring and control grid is controlled within 5 mm.

[0011] Furthermore, in the correction step of the monitoring and control grid, the surveying instrument is first controlled within an elevation and a correction platform is established; then, a correction line is marked on the correction platform according to the construction design requirements; and then, the surveying instrument is adjusted according to the error between the surveying line of the surveying instrument and the correction line measured by the measuring instrument.

[0012] Furthermore, when marking the calibration line on the calibration platform according to the construction design requirements, calibration line one is first marked on the calibration platform using a theodolite; then, according to the construction design requirements, calibration line two is marked on the calibration platform, and calibration line one is perpendicular to calibration line two.

[0013] Furthermore, the elevation error accuracy of the surveying and mapping instrument is controlled within 3mm.

[0014] Furthermore, the surveying line of the surveying instrument is in the same direction as the first correction line or the second correction line on the correction platform.

[0015] Furthermore, the surveying and mapping instruments include total stations, and the measuring instruments include steel rulers.

[0016] Furthermore, the calibration platform is a concrete platform or a steel platform.

[0017] Furthermore, in the correction step of the monitoring and control grid, the error accuracy of the corrected monitoring and control grid is controlled within 1 mm.

[0018] Furthermore, the prefabricated sheet pile planting step includes the following steps:

[0019] Adjust the position of the precast sheet piles and control the pile driver to move the precast sheet piles to the predetermined construction position according to the monitoring control grid;

[0020] Calibrate precast sheet piles, monitor their verticality before and during implantation, and control the pile driver to adjust the precast sheet piles in a timely manner.

[0021] Furthermore, in the step of adjusting the position of the precast sheet piles, auxiliary lines parallel to the pile edges are first marked on the precast sheet piles, and then the precast sheet piles are hoisted by the pile driver. Thereafter, according to the monitoring and control grid, the pile driver is controlled to adjust the position of the precast sheet piles so that the auxiliary lines on the precast sheet piles coincide with the corresponding surveying lines in the monitoring and control grid.

[0022] Furthermore, in the precast sheet pile calibration step, the verticality of the precast sheet pile hoisted on the pile driver is measured by a theodolite, and the data is fed back to the pile driver control system so that the pile driver can adjust the verticality of the precast sheet pile in time.

[0023] Alternatively, in the step of correcting the precast sheet piles, an inclinometer is installed in the inclinometer tube pre-buried in the precast sheet piles.

[0035] Example 1

[0036] See also Figure 1-Figure 3 This embodiment provides a prefabricated sheet pile planting construction method, including a monitoring and control grid establishment step and a subsequent prefabricated sheet pile planting step.

[0037] The step of establishing a monitoring and control grid includes preliminary establishment of the monitoring and control grid and correction of the monitoring and control grid. In the preliminary establishment of the monitoring and control grid, surveying instruments 1 are set at a plurality of predetermined locations according to construction design requirements to preliminarily establish the monitoring and control grid using the surveying instruments 1. In the correction of the monitoring and control grid, the error of the preliminarily established monitoring and control grid is measured using the surveying instruments, and the surveying instruments 1 are adjusted according to the error range required for construction so that the precast sheet pile construction positions formed by the monitoring and control grid meet the design requirements.

[0038] Specifically, the multiple predetermined positions are not collinear, that is, when the monitoring and control grid is initially established, the surveying lines 11 emitted by the surveying and mapping instrument 1 will intersect to form a monitoring and control grid. The intersection point is the precast sheet pile construction position of the construction design, or the position enclosed by the intersection of the surveying and mapping lines 11 is the precast sheet pile construction position, which is determined according to the time requirements during construction. When calibrating the monitoring and control grid, the surveying instrument is used to measure the distance between the surveying line 11 emitted by the surveying and mapping instrument 1 and the line, point, or surface that meets the construction design requirements. If the distance is within the error range of the construction requirements, there is no need to adjust the surveying and mapping instrument 1. If the distance is not within the error range of the construction requirements, the surveying and mapping instrument 1 is adjusted so that the surveying lines 11 emitted by the multiple surveying and mapping instruments 1 form a monitoring and control grid, and pile construction is performed according to the calibrated monitoring and control grid.

[0039] Specifically, during the initial establishment of the monitoring and control grid, corner points are first determined based on the construction site, and corner surveying instruments are installed at these locations. Next, at least one intermediate surveying instrument is installed along the surveying lines 11 of adjacent corner surveying instruments, according to the construction design requirements. The surveying lines 11 of the corner and intermediate surveying instruments intersect to form the monitoring and control grid. Preferably, the surveying lines 11 emitted by the corner surveying instruments are sequentially connected and enclosed, with the intermediate surveying instruments emitting surveying lines 11 on the opposite side. During the calibration step of the monitoring and control grid, the surveying instrument 1 is first controlled within a certain elevation, and a calibration platform 2 is established. Preferably, the calibration platform 2 is a concrete or steel platform, and the calibration platform 2 is at least 300 mm by 500 mm. A calibration line 4 is then marked on the calibration platform 2 according to the construction design requirements. The surveying instrument 1 is then adjusted based on the error between the surveying line 11 of the surveying instrument 1 and the calibration line 4, as measured by the measuring instrument. Specifically, the calibration platform 2 is first established according to the construction design requirements, the calibration line 4 is marked, and the spacing between the surveying line 11 and the calibration line 4 is measured using the calibration line 4 as a reference. If the spacing is within the error range required for construction, the corresponding surveying instrument 1 does not need to be adjusted. If the spacing is not within the error range required for construction, the corresponding surveying instrument 1 is adjusted. The calibration platform 2 can protect the surveying instrument 1. The surveying instrument 1 can include, but is not limited to, a total station, as long as it can achieve the establishment of the monitoring and control grid. The surveying instrument can include, but is not limited to, a steel ruler, as long as it can measure the error between the surveying line 11 and the calibration line 4.

[0040] For further information, see Figure 6 When marking the calibration line 4 on the calibration platform 2 according to the construction design requirements, first use the theodolite 3 to mark the calibration line 1 41 on the calibration platform 2; then, according to the construction design requirements, mark the calibration line 2 42 on the calibration platform 2, and the calibration line 1 41 is perpendicular to the calibration line 2 42. Preferably, the calibration line 1 41 is in the same direction as the surveying line 11 emitted by the corner point surveying instrument, and the position and direction of the corner point surveying instrument are corrected by the calibration line 1 41. Preferably, the calibration line 2 42 is in the same direction as the surveying line 11 emitted by the intermediate surveying instrument, and the position and direction of the intermediate surveying instrument are corrected by the calibration line 2 42. Among them, the calibration line 1 41 can be an ink line marked on the calibration platform 2 with reference to the line emitted by the theodolite 3, and the ink line coincides with the line emitted by the theodolite 3. The calibration line 2 42 is an ink line marked on the calibration platform 2 with reference to the calibration line 1 41.

[0041] Furthermore, in the initial establishment step of the monitoring and control grid, the error accuracy of the initially established monitoring and control grid is controlled within 5 mm to avoid a large deviation of the formed monitoring and control grid and thus affect subsequent corrections.

[0042] Furthermore, in the correction step of the monitoring and control grid, the error accuracy of the corrected monitoring and control grid is controlled within 1 mm, so as to accurately position the construction of the precast sheet piles 10 to meet the design requirements.

[0043] Furthermore, the elevation error accuracy of the surveying and mapping instrument 1 is controlled within 3 mm, preferably within 1 mm.

[0044] Example 2

[0045] In this embodiment, the same parts as those in the first embodiment are given the same reference numerals, and the same text descriptions are omitted.

[0046] See also Figure 1-6 Compared with the first embodiment, the prefabricated sheet pile construction method provided in this embodiment has the following different structural designs:

[0047] The precast sheet pile planting step includes adjusting the position of the precast sheet pile 10 and correcting the precast sheet pile 10. In the precast sheet pile position adjustment step, the pile driver is controlled to adjust the precast sheet pile 10 thereon to the predetermined construction position according to the monitoring and control grid. In the precast sheet pile correction step, the verticality of the precast sheet pile 10 before and during implantation is monitored, and the pile driver is controlled to promptly adjust the precast sheet pile 10. That is, after obtaining an accurate monitoring and control grid according to Example 1, the position of the precast sheet pile 10 is adjusted by reference to the monitoring and control grid so that the precast sheet pile 10 is implanted from the predetermined construction position. The verticality of the precast sheet pile 10 is monitored before and during implantation and promptly adjusted to accurately implant the sheet pile, thereby ensuring that the implanted precast sheet pile 10 meets the construction design requirements and can be connected to other components during subsequent assembly and docking. The pile driver is positioned according to the monitoring and control grid.

[0048] For details, see Figure 4 In the step of adjusting the position of the precast sheet pile, an auxiliary line parallel to the pile edge is first marked on the precast sheet pile 10, and then the precast sheet pile 10 is hoisted by the pile driver. After that, according to the monitoring and control grid, the pile driver is controlled to adjust the position of the precast sheet pile 10 so that the auxiliary line on the precast sheet pile 10 coincides with the corresponding surveying line 11 in the monitoring and control grid.

[0049] In the step of correcting the precast sheet piles, the verticality of the precast sheet piles 10 hoisted on the pile driver is measured by the theodolite 3, and the feedback is given to the control system of the pile driver so that the pile driver can adjust the verticality of the precast sheet piles 10 in time. Alternatively, in the step of correcting the precast sheet piles, an inclinometer is installed in the inclinometer tube pre-buried in the precast sheet piles 10, and the inclinometer measures the verticality of the precast sheet piles 10 and the feedback is given to the control system of the pile driver so that the pile driver can adjust the verticality of the precast sheet piles 10 in time.

[0050] See also Figure 5When measuring the verticality of the prefabricated sheet pile 10 hoisted on the pile driver using the theodolite 3, a theodolite 3 is installed on the vertical and horizontal axes respectively. First, aim at the bottom edge of the pile, and then gradually look up to the top of the pile. If the pile edge deviates from the line of sight, it means that the pile is not vertical, and the pile driver can be instructed to adjust.

Several improvements and modifications made by those skilled in the art without departing from the spirit and scope of the present invention should also be regarded as the scope of protection of the present invention.
