[0002] When prefabricated pipe pile construction is carried out in complex environment (complex geological structure, large fluctuation of construction site, various design elevations of pile top), the traditional prefabricated pipe pile construction process has the following problems:
[0003] 1. The calculation of pile length depends on manual work, which is prone to calculation deviation due to uneven thickness of bearing layer, change of site elevation and other factors, resulting in pile cutting or pile connecting phenomenon and increasing pipe pile loss (loss rate is usually 3%-4%);
[0004] 2. Construction parameters (site elevation, pile top elevation, depth of soil penetration, etc.) need to be memorized and transmitted manually, which is prone to human error and affects construction quality;
[0005] 3. Pile position setting only uses plane coordinate setting, without real-time correction combined with ground elevation, resulting in low pile setting accuracy;

[0008] In order to achieve the above purpose, the present application provides a prefabricated pipe pile information construction method in complex environment, comprising the following steps:
[0009] Based on the absolute position or relative position of pile point and hole exploration position of prefabricated pipe pile, the bearing layer elevation at the pile point is automatically calculated by Excel table;
[0010] According to design requirements and pile test results, the pile tip elevation is determined;
[0011] An Excel table of pipe pile pile setting parameters is constructed, and the construction control parameters are automatically calculated by inputting the bearing layer elevation, pile top design elevation, reserved pile length, natural ground elevation, pile head surplus height and correction value, the construction control parameters including pile length and depth of soil penetration of pile top;

[0014] When the pile driving operation result deviates greatly and the current prefabricated pipe pile needs to be cut or connected, the pile length of the last prefabricated pipe pile is input as the correction value of the pile length of the next prefabricated pipe pile into the pipe pile parameter summary Excel table to obtain the corrected pile length of the next prefabricated pipe pile.
[0015] Further, the absolute position includes the three-dimensional coordinates of the pile point and the three-dimensional coordinates of the hole exploration site, and the Excel table automatically calculates the bearing layer elevation at the pile point by a calculation formula.
[0016] Further, when the hole exploration site is two, the calculation formula is:
[0017] H_x=\frac{a}{a+b}H_b+\frac{b}{a+b}H_a,
[0018] Where H_x is the bearing layer elevation at the pile point;
[0019] a and b are the horizontal distances from the pile point to the two holes;
[0020] H_a and H_b are the bearing layer elevations at the two holes, respectively.
[0021] Further, when the hole exploration site is three, the calculation formula is:
[0022] H_x=\left(\frac{a+c}{a+b+c}H_b+\frac{b+c}{a+b+c}H_a+\frac{a+b}{a+b+c}H_c\right) / 2,

[0025] H_a, H_b, and H_c are the bearing layer elevations at the three holes.
[0026] Further, when the number of holes is N, the calculation formula is:
[0027] H_x = \left(\frac{1}{N-1}\right)sum_{i=1}^{N}\left(\frac{b-a_i}{b}H_i\right),
[0028] H_x is the bearing stratum elevation at the pile point position;
[0029] b is the sum of the horizontal distance from each exploration hole to the pile point position;
[0030] a_i is the horizontal distance from the i-th exploration hole to the pile point position.

It can be understood that the specific embodiments described herein are only used to explain the related application, but not to limit the application. In addition, it should be noted that only the parts related to the application are shown in the drawings for convenience of description.
[0038] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0039] Referring to Figures 1 to 4 The present application provides a prefabricated pipe pile information construction method in a complex environment, comprising the following steps:
[0040] S1, based on the absolute position or relative position of the pile point and the hole exploration position of the prefabricated pipe pile, the bearing layer elevation at the pile point is automatically calculated by an Excel table.
[0041] In the present embodiment, the absolute position includes the three-dimensional coordinates of the pile point and the three-dimensional coordinates of the hole exploration position, and the Excel table automatically calculates the bearing layer elevation at the pile point by a calculation formula.
[0042] Specifically, when the hole exploration position is two, the calculation formula is:
[0043] H_x=\frac{a}{a+b}H_b+\frac{b}{a+b}H_a,
[0044] wherein H_x is the bearing layer elevation at the pile point;
[0045] a and b are the horizontal distances from the pile point to the two holes;
[0046] H_a and H_b are the bearing layer elevations at the two holes, respectively.
[0047] When the hole exploration position is three, the calculation formula is:
[0048] H_x=\left(\frac{a+c}{a+b+c}H_b+\frac{b+c}{a+b+c}H_a+\frac{a+b}{a+b+c}H_c\right) / 2,
[0049] wherein H_x is the bearing layer elevation at the pile point;
[0050] a, b and c are the horizontal distances from the pile point to the three holes;
[0051] H_a, H_b and H_c are the bearing layer elevations at the three holes.
[0052] When the number of holes is N, the calculation formula is:
[0053] H_x = \left(\frac{1}{N-1}\right)\sum_{i=1}^{N}\left(\frac{b-a_i}{b}H_i\right),
[0054] wherein H_x is the bearing stratum elevation at the pile point position;
[0055] b is the sum of the horizontal distances from each probe hole to the pile point position;
[0056] a_i is the horizontal distance from the i-th probe hole to the pile point position.
[0057] In some embodiments, based on the relative distance between the known probe hole position and the pile point position of the precast pile, the bearing stratum elevation at the pile point position is automatically calculated by an Excel table, which specifically includes the following steps:
[0058] Referring to Figure 2 , an Excel table is established, a "pile position elevation calculation table" is drawn from the top left corner, and a start button is added; then the software program is input to the "start button" through the Excel VB editor.
[0059] The probe hole elevation value (up to 3) is input in the white box on the top left, then the probe hole number (such as A, B, C) and the pile position number (such as 1, 2, 3, etc.) are input in the yellow and pink boxes according to the relative positions of each position, and finally the red start button is pressed, and the calculation result will be directly displayed in the white box on the left.
[0060] The "pile position elevation calculation table" can calculate up to 16 pile point elevations at a time. Although this calculation table only roughly estimates the pile position elevation, since the actual pile length is generally an integer in meters, such as 9m, 11m, 13m, 15m, etc., the calculation error caused by estimation is still within an acceptable range.
[0061] When determining the elevation Hx (i.e. the pile position elevation) of any hole position on the line connecting two probe holes, then:
[0062]
[0063] wherein Ha is the elevation of probe hole a;
[0064] Hb is the elevation of probe hole b;
[0065] a is the straight-line distance from probe hole a to any hole position;
[0066] b is the straight-line distance from probe hole b to any hole position.
[0067] When there are N probe holes at the pile position, the pile position elevation is calculated using the following formula:
[0068]
[0069] wherein N>1;
[0070] ai is the straight-line distance (horizontal distance) from the i-th sounding hole to the pile position;
[0071] b=a1+a2+···.+ai.
[0072] The pile position elevation calculation table is automatically calculated using the above formula.
[0073] S2, according to the design requirements and the test pile results, determine the pile tip elevation.
[0074] Specifically, according to the design requirements and the test pile results, determine the pile tip into the bearing stratum depth, and the result is added to the pile position elevation.
[0075] S3, construct a pipe pile pile parameter summary Excel table (such as Figure 4 As shown), by inputting the bearing stratum layer elevation, the pile top design elevation, the reserved pile length, the natural ground elevation, the pile head surplus height and the correction value to automatically calculate the construction control parameters using the pipe pile pile parameter summary Excel table, the construction control parameters include the pile length and the pile top into the soil depth.
[0076] The pipe pile pile parameter summary Excel table is in the form of an Excel table, which can be directly opened and edited with a mobile phone or a tablet computer on the construction site. When using:
[0077] 1) The white area is the manual data input area, and the green area is the automatically generated construction site control parameter area, among which the pile length and the pile top into the soil depth are the most important, which should be reported to the supervision for review before piling.
[0078] 2) The natural ground elevation is taken as the average elevation value in the construction drawing when input for the first time, and is modified in real time according to the pile point elevation measurement results on site.
[0079] 3) The correction value is generally zero or blank. When the piling operation result deviates greatly, the pile length correction value of the next pile adjacent to it is the (actual pile length-pile length) of the previous pile when the pile needs to be cut or connected.
[0080] 4) The number 2 appearing in the green area is valued according to (pile tip into bearing stratum depth 1.5m+ calculation error correction 0.5m), which can be directly modified in the Excel table according to the actual situation.
[0081] S4, field setting out and measuring ground elevation, and inputting the ground elevation as the natural ground elevation into the pipe pile pile parameter summary Excel table to obtain the corrected pile length.
[0082] 1) Measurement benchmarks or control lines for the pile locations should be laid out according to the pile location plan. The benchmarks (lines) should be laid out with good visibility, not easily moved, and properly protected.
[0083] 2) Change the original conventional planar pile point layout mode to implement the (planar pile point layout + pile point ground elevation) measurement mode. While laying out the pile points, measure the ground elevation of the pile points and directly input the results into the "Pipe Pile Matching Parameter Summary Excel Table".
[0084] 3) After the pile locations are laid out, conduct a self-inspection first. After the self-inspection is qualified, conduct a re-inspection. The relevant deviation requirements are shown in Table 1 below.
[0085] 4) After passing the re-inspection, report to the supervision unit for inspection, acceptance and confirmation, and prepare a written document for future reference.
[0086] Table 1, Allowable deviations for stakeout Difference
[0087] No. Item Allowable deviation (mm) 1 Grouped piles 20 2 Single row piles 10
[0088] S5. Dynamic pile layout and pile driving based on the revised construction control parameters.
[0089] Combination Figure 3 As shown, the entire piling operation should be carried out in strict accordance with the requirements of relevant national operating procedures.
[0090] S6. When there is a large deviation in the piling operation results and the current precast pipe pile needs to be cut or spliced, the pile length of the previous precast pipe pile is used as the correction value for the pile length of the next precast pipe pile and entered into the pile pile parameter summary Excel table to obtain the corrected pile length of the next precast pipe pile.
[0091] After the piling operation is completed, the operators should promptly input the piling adjustment values into the "Summary Excel Table of Pipe Pile Piling Parameters" according to the operation situation and as needed.
[0092] This invention provides an information-based construction method for precast pipe piles in complex environments. It automatically outputs the bearing stratum elevation of the pile location using an Excel spreadsheet, eliminating errors from manual calculations, by providing the absolute or relative positions of borehole locations and pile points. A summary Excel spreadsheet of pipe pile configuration parameters automatically integrates parameters such as pile elevation, site elevation, pile top design elevation, and bearing stratum depth, generating construction control parameters such as pile length and pile top penetration depth. The method employs a "plane coordinate layout + ground elevation measurement" mode to obtain ground elevation measurement data for the pile locations. On-site technicians input this data in real-time using tablets or mobile phones to automatically correct the pile length. After a single pile is constructed, the correction values for adjacent pile configurations are entered, automatically backtracking and correcting historical calculation results to continuously improve pile configuration accuracy.
[0093] The precast pipe pile information construction method under the complex environment of the application controls the pile length calculation error within the allowable range (because the pile length is selected by integer meters), reduces the pile cutting and splicing phenomenon, and improves the construction precision.
[0094] The precast pipe pile information construction method under the complex environment of the application reduces the pipe pile loss rate from 3% to 4% to about 1.3%, and significantly saves material cost.
[0095] The construction control parameter automatic calculation and real-time correction of the precast pipe pile information construction method under the complex environment of the application reduces the manual operation time, and the construction efficiency is improved by more than 20%, thereby improving the construction efficiency.
[0096] The precast pipe pile information construction method under the complex environment of the application realizes the digital transmission and dynamic adjustment of construction parameters, reduces human errors, is convenient for quality tracing, and realizes information management.
[0097] In the prior art, part of the construction method attempts to assist calculation through an Excel table or manual measurement correction, but lacks a systematic information integration scheme, does not realize closed-loop control of automatic calculation, real-time feedback and dynamic correction, and is difficult to adapt to the high-precision construction demand under complex environment.
[0098] The above description is only the preferred embodiment of the application and the explanation of the applied technical principles. It should be understood by those skilled in the art that the application range involved in the application is not limited to the technical solutions formed by the specific combination of the above technical features, and also covers other technical solutions formed by any combination of the above technical features or equivalent features without departing from the inventive concept. For example, the technical solutions formed by replacing the above features with the technical features disclosed in the application (but not limited to) having similar functions.
