Description

Technical Field

[0001] This invention belongs to the field of civil engineering construction technology, specifically relating to an intelligent construction system and method for pile group cutting construction. Background Technology

[0002] Concrete-poured pile foundations are a conventional form of foundation reinforcement structure. To ensure the quality of the pile foundations and their effective connection with the superstructure, it is usually required that the piles be over-poured to a certain height during construction, such as 0.5 to 1 meter, depending on the design drawings. Before constructing the superstructure, the pile head (i.e., the over-poured concrete portion) needs to be chiseled or cut off. Traditional pile head removal methods typically involve manual chiseling with tools such as pneumatic picks, followed by hoisting with a crane. This method has many drawbacks, including high labor and machinery costs, significant construction safety risks, and low levels of mechanization.

[0003] Currently, mobile pile cutters have been developed for cutting off the heads of individual piles. However, the foundations of modern buildings, bridges, and other engineering projects typically employ pile group reinforcement. Using a single mobile pile cutter to sequentially cut off the heads of individual piles is inefficient. Therefore, it is necessary to develop an intelligent construction system and method for pile group cutting. Summary of the Invention

[0004] To address the problem of low efficiency in the construction method of pile head removal when using pile group reinforcement for existing foundations, this invention provides an intelligent construction system and method for pile head removal construction, which can effectively improve construction efficiency.

[0005] To solve the above technical problems, the present invention includes the following technical solutions:

[0006] An intelligent construction system for pile group cutting construction includes a pile group cutting construction BIM model, a construction progress database, several mobile pile cutting machines, wireless data transmission and reception equipment, and a pile cutting machine control center.

[0007] The model data of the pile group cutting construction BIM model includes concrete cast-in-place pile design data and construction data. The pile group cutting construction BIM model is a concrete cast-in-place pile BIM model constructed with design data as the bottom layer model data and construction data as the upper layer comparison model data.

[0008] The construction progress database contains the following information: concrete cast-in-place pile design parameters, casting construction parameters, allowable pile cutting time, and pile cutting construction parameters;

[0009] The pile cutting machine control center determines the daily construction operation plan based on the construction progress database and the pile cutting construction BIM model, and sends operation instructions to the mobile pile cutting machine and monitors the pile cutting operation status and results of the mobile pile cutting machine through the data wireless transmission and reception equipment.

[0010] The mobile pile cutter can transmit data through a wireless data transmission and reception device, receive operation instructions from the pile cutter control center, carry out construction operations according to the instructions, and send feedback on the pile cutting construction operation status and effect to the pile cutter control center.

[0011] Accordingly, the present invention also provides an intelligent construction method for pile group cutting construction, which is based on the intelligent construction system for pile group cutting construction. The construction method includes the following steps:

[0012] Step 1: Obtain model data from engineering design drawings to construct a BIM model for pile group cutting construction, and construct a construction progress database based on design data;

[0013] Step 2: The pile cutting machine control center determines the daily construction operation plan based on the data information from the construction progress database and the BIM model of the pile cutting construction.

[0014] Step 3: The pile cutting machine control center sends the day's construction operation plan to each mobile pile cutting machine via wireless data transmission and reception equipment.

[0015] Step 4: The mobile pile cutter receives instructions via wireless data transmission and reception equipment and performs construction operations according to the instructions;

[0016] Step 5: After completing the cutting of each concrete pile, the mobile pile cutter sends feedback on the pile cutting operation status and effect to the pile cutter control center.

[0017] Step 6: The pile cutting machine control center synchronously sends updated data to the construction progress database and the pile cutting construction BIM model, updating the construction comparison model of the pile cutting construction BIM model and the pile cutting construction parameters of the construction progress database.

[0018] Step 7: Repeat steps 2 through 6 until all pile group cutting construction is completed.

[0019] Furthermore, in step two, the pile cutting machine control center determines the day's construction operation plan based on the data information from the construction progress database and the BIM model of the pile cutting construction, specifically including the following steps:

[0020] Step A1. Based on the construction progress database and the BIM model of pile group cutting construction, retrieve the concrete pouring pile number that is allowed to be cut before the current time.

[0021] Step A2. Read the center coordinates of the concrete pile corresponding to the concrete pile number;

[0022] Step A3. Determine the movement path scheme based on the individual pile-cutting performance of the M mobile pile cutters; the movement path can be calculated using mathematical optimization or machine learning intelligent algorithms.

[0023] Step A4. The pile cutting machine control center sends operation instructions to each mobile pile cutting machine according to the movement path plan.

[0024] Furthermore, in step three, the pile cutting machine control center sends the day's construction operation plan to each mobile pile cutting machine via a data wireless transmission and reception device. This transmission and reception includes a route plan for the mobile pile cutting machine, which is obtained through the following steps:

[0025] Step B1. Based on the engineering plan, establish a plane rectangular coordinate system xOy, number the N concrete piles that meet the conditions for pile cutting construction, and determine their coordinate positions. The coordinates of the i-th concrete pile are marked as P. i (x i ,y i ), i = 1, 2, ..., N;

[0026] Step B2. With the goal of minimizing distance, find the overall shortest construction route for N concrete piles, and form a point set R according to the order of the concrete pile locations corresponding to the overall shortest construction route. Renumber the N points in R to obtain R{P (1) ,...,P (n) ,...,P (N)}, n = 1, 2, ..., N;

[0027] Step B3. With the objective of minimizing time, determine the optimal route for the M mobile pile cutters; including:

[0028] R{P (1) ,...,P (n) ,...,P (N) The ordered partitioning is divided into M subsets, denoted as R1, R2, ..., Rn. M Let the construction route of the j-th mobile pile cutter be denoted as R. j {R ji i = 1, 2, ..., N j}, j = 1, 2, ..., M, N j For set R j The number of elements in R ji For R j The i-th element in; then,

[0029] R{P(1) ,...P (n) ,...P (N)}=R1+R2...+R M ;

[0030]

[0031] In the formula, And K M =N, K0=0, K M =N;

[0032] Let S be the length of the construction route of the j-th mobile pile cutter. Rj ,but,

[0033] In the formula, d i(i+1) For R j The distance between the concrete piles corresponding to two adjacent elements numbered i and i+1; T R =max{T R1 ,..,T Rj ,..,T RM}

[0034] Determine the moving speed v0 of the mobile pile cutter and the pile cutting construction time T0 for each concrete pile. The construction time of the j-th mobile pile cutter is denoted as T. Rj ,but,

[0035] Find T Rj The maximum value in is denoted as T. R The distance between T and T; then, T R =max{T R1 ,..,T Rj ,..,T RM};

[0036] By adjusting R j N in j The value is obtained to determine the different construction routes of M mobile pile cutters, and the value of T is calculated for all construction routes. R Minimum value T Rmin T Rmin The corresponding construction route is the optimal construction route for M available mobile pile cutters.

[0037] This invention, by employing the above technical solutions, offers the following advantages and positive effects compared to existing technologies: The invention provides an intelligent construction system and method for pile group cutting construction. It constructs a BIM model and construction progress database for pile group cutting construction. The pile cutting machine control center transmits the daily construction work plan to the mobile pile cutting machine via wireless data transmission and reception equipment. The mobile pile cutting machine performs construction operations according to the work instructions and feeds back the construction operation status and results to the pile cutting machine control center. This ensures timely updates to the pile group cutting construction BIM model and construction progress database, thereby achieving intelligent pile cutting control and monitoring. For pile group construction, especially for large-scale pile group cutting, this invention reduces labor and machinery input, lowers construction safety risks, and offers significant advantages such as high construction efficiency and a high level of intelligence, informatization, and digitalization compared to traditional pile head processing techniques. Furthermore, the intelligent construction method for pile group cutting construction provided by this invention also includes a path planning method, offering a reasonable construction path to shorten construction time and improve construction efficiency. Attached Figure Description

[0038] Figure 1 This is a block diagram of an intelligent construction system for pile group cutting construction according to an embodiment of the present invention. Detailed Implementation

[0039] The intelligent construction system and method for pile group cutting construction provided by the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0040] Example 1

[0041] like Figure 1 As shown in the figure, the intelligent construction system for pile group cutting construction provided in this embodiment includes a pile group cutting construction BIM model, a construction progress database, a pile cutting machine control center, several mobile pile cutting machines, and data wireless transmission and reception equipment.

[0042] The BIM model for pile group cutting construction is based on model data obtained from engineering design drawings. The model data includes: concrete cast-in-place pile number, design pile diameter, design pile length, design concrete grade, design coordinates of pile center, design elevation of pile top, design elevation of pile cutting, pile diameter, pile length, concrete grade, pile center coordinates, pile top elevation, etc. after construction. Based on the above model data, with the concrete cast-in-place pile design data as the bottom layer model data and the construction data as the upper layer comparison model data, a 3D layout BIM model of concrete cast-in-place piles is constructed.

[0043] The construction progress database is a real-time, dynamically updated database containing information on the construction of concrete cast-in-place piles and its influencing factors. The information mainly includes: concrete cast-in-place pile design parameters, pouring construction parameters, allowable pile cutting time, and pile cutting construction parameters. It is updated in real-time based on the construction site conditions to track the progress of concrete cast-in-place pile cutting and its influencing factors. The concrete cast-in-place pile design parameters include: pile number, design pile diameter, design pile length, design concrete grade, pile center design coordinates, pile top design elevation, and pile cutting design elevation. The pouring construction parameters include: pile diameter, pile length, concrete grade, pile center coordinates, pile top elevation, and pouring time. The pile cutting construction parameters include: pile diameter, pile length, pile center coordinates, pile top elevation, and pile cutting time. The allowable time for pile cutting is determined based on the construction site conditions. For each numbered concrete cast-in-place pile, factors affecting pile cutting construction, such as concrete age, foundation pit excavation, backfilling, dewatering, and clearance height, are excluded. The earliest time for pile cutting construction can be carried out only after the conditions for pile cutting construction are met (such as completion of preliminary procedures and ground bearing capacity).

[0044] The pile cutting machine control center is a computer or other device with data processing capabilities. Based on the construction progress database and the BIM model of the pile cutting construction, it determines the daily construction operation plan and sends operation instructions to the mobile pile cutting machine via wireless data transmission and reception equipment, monitoring the pile cutting operation status and results. The operation instructions include information such as the pile number, pile diameter, concrete grade, pile center coordinates, and design elevation for pile cutting. The mobile pile cutting machine's operation status and results include pile diameter, pile length, pile center coordinates, pile top elevation, cutting time, and on-site image data.

[0045] The method by which the pile cutting machine control center determines the construction operation plan for the day is as follows: ① Based on the construction progress database and the BIM model of pile cutting construction, the concrete pile numbers with "allowed pile cutting time" before the current time are read out; ② The center coordinates of these concrete pile numbers are then read out; ③ For N mobile pile cutting machines and their respective pile cutting performance (pile diameter range, unit operation time), the movement path planning mathematical optimization or machine learning intelligent algorithm is used to calculate; ④ N corresponding pile cutting movement route plans are solved. The pile cutting machine control center will then send operation instructions (i.e., information data such as the pile number, pile diameter, concrete grade, pile center coordinates, and pile cutting design elevation) to each mobile pile cutting machine according to the plan.

[0046] The mobile pile cutter is a type of mechanical equipment that can move and cut off the concrete pile head above the design elevation of a cast-in-place concrete pile and complete the pile head treatment. It receives operation instructions from the pile cutter control center, performs construction operations according to the instructions, and sends feedback on the pile cutting construction operation status and effect to the pile cutter control center, including pile diameter, pile length, pile center coordinates, pile top elevation, pile cutting time, and on-site image data.

[0047] The wireless data transmission and reception device is installed on the pile cutting machine control center and each mobile pile cutting machine, and is a functional device for transmitting and receiving data information between the pile cutting machine control center and the mobile pile cutting machine.

[0048] Example 2

[0049] This embodiment provides an intelligent construction method for pile group cutting construction. This construction method is based on an intelligent construction system for pile group cutting construction and specifically includes the following steps:

[0050] Step 1: Obtain model data from engineering design drawings to construct a BIM model for pile group cutting construction, and construct a construction progress database based on design data;

[0051] Step 2: The pile cutting machine control center determines the daily construction operation plan based on the data information from the construction progress database and the BIM model of the pile cutting construction.

[0052] Step 3: The pile cutting machine control center sends the day's construction operation plan to each mobile pile cutting machine via wireless data transmission and reception equipment.

[0053] Step 4: The mobile pile cutter receives instructions via wireless data transmission and reception equipment and performs construction operations according to the instructions;

[0054] Step 5: After completing the cutting of each concrete pile, the mobile pile cutter sends feedback on the pile cutting operation status and effect to the pile cutter control center.

[0055] Step 6: The pile cutting machine control center synchronously sends updated data to the construction progress database and the pile cutting construction BIM model, updating the construction comparison model of the pile cutting construction BIM model and the pile cutting construction parameters of the construction progress database.

[0056] Step 7: Repeat steps 2 through 6 until all pile group cutting construction is completed.

[0057] The BIM model for pile group cutting construction can intuitively display all pile group cutting construction tasks, the progress and effects of completed pile foundations, and construction anomalies in a 3D visualization model.

[0058] In step two, the pile cutting machine control center determines the day's construction operation plan based on the data information from the construction progress database and the BIM model of the pile cutting construction. This includes the following steps:

[0059] Step A1. Based on the construction progress database and the BIM model of pile group cutting construction, retrieve the concrete pouring pile number that is allowed to be cut before the current time.

[0060] Step A2. Read the center coordinates of the concrete pile corresponding to the concrete pile number;

[0061] Step A3. Determine the movement path scheme based on the individual pile-cutting performance of the M mobile pile cutters; the movement path can be calculated using mathematical optimization or machine learning intelligent algorithms.

[0062] Step A4. The pile cutting machine control center sends operation instructions to each mobile pile cutting machine according to the movement path plan.

[0063] In step three, the pile cutter control center sends the day's construction work plan to each mobile pile cutter via wireless data transmission and reception equipment. The instructions include the mobile pile cutter's route, and different route schemes can be set based on optimal time, optimal distance, or minimum power consumption. This embodiment provides a mobile pile cutter route planning method, including the following steps:

[0064] Step B1. Determine the coordinate position of each concrete pile; specifically, based on the engineering plan, establish a plane rectangular coordinate system xOy, number the N concrete piles that meet the conditions for pile cutting construction, and determine their coordinate positions. The coordinates of the i-th concrete pile are marked as P. i (x i ,y i ), i = 1, 2, ..., N.

[0065] Step B2. With the goal of minimizing distance, find the overall shortest construction route for N concrete piles, and form a point set R according to the order of the concrete pile locations corresponding to the overall shortest construction route. Renumber the N points in R to obtain R{P (1) ,...,P (n) ,...,P (N)}, n=1,2,…,N.

[0066] In mathematics, there are many algorithms for finding the shortest construction route, such as the Floyd-Warshall algorithm, Dijkstra's algorithm, and Bellman-Ford algorithm.

[0067] The set R is a sequence of points corresponding to the overall shortest construction route for N concrete piles, containing N elements, each representing the coordinates of one of the N concrete piles. Since the overall shortest construction route is one of many construction routes, the indices of the elements in R corresponding to the overall shortest construction route may not be R{P}. i (x i ,y i The order and numbering of elements in R, i = 1, 2, ..., N, are likely irregular and inconvenient to describe. Therefore, the elements in R corresponding to the overall shortest construction route are renumbered and represented in superscript form, i.e., R{P (1) ,...,P (n) ,...,P (N)}, n=1,2,…,N.

[0068] Step B3. With the objective of minimizing time, determine the optimal route for the M mobile pile cutters; including:

[0069] (1) Establish a construction route model for M mobile pile cutters, specifically as follows:

[0070] R{P (1) ,...,P (n) ,...,P (N) The ordered partitioning is divided into M subsets, denoted as R1, R2, ..., Rn. M When splitting, no elements in R are omitted and the element numbers of the M subsets are consecutive, with the element numbers of each subsequent subset being greater than the element numbers of the preceding subset; R is then split. j As the construction route for the jth mobile pile cutter, R j {R ji i = 1, 2, ..., N j}, j = 1, 2, ..., M, N j For a subset R j The number of elements in R ji For R j The i-th element in, 1≤N j If ≤NM, then it satisfies the following condition.

[0071] R{P (1) ,...P (n) ,...P (N)}=R1+R2...+R j ...+R M ;

[0072]

[0073] In the formula, And K0 = 0, K M=N; N i N j Let R1 and R2 represent the number of concrete piles constructed by the i-th and j-th mobile pile cutters, respectively, which are also the number of elements in the corresponding subset; for example, for the 1st mobile pile cutter, corresponding to j=1, the construction route R1={P} (1) ,P (2) ,...,P (N1)}, the second mobile pile cutter, corresponding to j=2, construction route R1={P (N1+1) ,P (N1+2) ,...,P (N1+N2)}, and so on for the others;

[0074] (2) Calculate the construction route length S in the construction route model for each mobile pile cutter. Rj Specifically:

[0075] R j N in j Each element corresponds to N j There are N ordered concrete pile locations, corresponding to N j -1 pile spacing, the construction route length of the j-th mobile pile cutter is denoted as S. Rj ,but,

[0076] In the formula, d i(i+1) Let P be the distance between the concrete piles corresponding to two adjacent points i and i+1; the coordinates of the concrete piles corresponding to points i and i+1 are P. i (x i ,y i ), P i+1 (x i+1 ,y i+1 ),available,

[0077]

[0078] (3) Calculate the construction time T in the construction route model for each mobile pile cutter. Rj And find the maximum value T. R Specifically:

[0079] Assuming the construction time of the mobile pile cutter includes the time for moving between concrete piles and the time for cutting the pile head, determine the moving speed v0 of the mobile pile cutter, the pile cutting time T0 for each concrete pile, and denot the construction time of the j-th mobile pile cutter as T. Rj ,but,

[0080] Find T Rj The maximum value in is denoted as T. R ,but,

[0081] T R =max{T R1 ,..,T Rj ,..,T RM};

[0082] (4) Solve for T R Minimum value T Rmin Specifically:

[0083] By adjusting R j N in j The value is obtained to determine the different construction routes of M mobile pile cutters, and the value of T is calculated for all construction routes. R Minimum value T Rmin T Rmin The corresponding construction route is the optimal construction route for M available mobile pile cutters.

[0084] Furthermore, by adjusting R j N in j The value is obtained to determine the different construction routes of M mobile pile cutters, and the value of T is calculated for all construction routes. R Minimum value T Rmin Specifically, it includes the following steps:

[0085] Step C1. Calculate the average value N0 and the remainder ΔN, where N0 = N / M and ΔN = N%M;

[0086] Step C2. For R j The number of elements N j Assign a value if N is less than or equal to j. j =N0+1, otherwise, N j =N0; where a is the number of cycles and T is the maximum construction time. R Assignment, a = 0, T R =+∞;

[0087] Step C3. Let N[M] represent the set of the number of elements, then N[M] = [N1, N2, ..., N] j ,...,N M ];at this time,

[0088] R{P (1) ,...P (n) ,...P (N)}=R1+R2...+R j ...+R M ; And K0 = 0, K M =N;

[0089] Step C4. Solve for the construction route length of the j-th mobile pile cutter, denoted as S. Rj and construction time T Rj ;

[0090] In the formula, d i(i+1) Let P be the distance between the concrete piles corresponding to two adjacent points i and i+1; the coordinates of the concrete piles corresponding to points i and i+1 are P. i (x i ,y i ), P i+1 (x i+1 ,y i+1 ),available,

[0091]

[0092] Step C5. Solve for the maximum value T Rmax and minimum value T Rmin , and T Rmax and minimum value T Rmin The corresponding subset numbers k max k min ;

[0093] T Rmax =max{T R1 ,..,T Rj ,..,T RM},k max ={k:T Rk ≥T Rj j = 1, 2, ..., M, k ∈ [1, M]};

[0094] T Rmin =min{T R1 ,..,T Rj ,..,T RM},k min ={k:T Rk ≤T Rj j = 1, 2, ..., M, k ∈ [1, M]};

[0095] Step C6. If T Rmax <T R Then let T R =T Rmax Proceed to step B6, if T Rmax ≥T R Then proceed directly to step C7;

[0096] Step C7. If Let a = a + 1, Proceed to step C3; if Proceed to step C8;

[0097] Step C8. Output T R N[M] = [N1, N2, ..., N M ]、
