Description
Technical Field
The application relates to the technical field of intelligent construction of pile foundations, in particular to a foundation pile construction method, system and storage medium based on big data.
Background
The pile foundation is a deep foundation in which the tops of a plurality of piles are connected into a whole through a bearing platform to bear dynamic and static loads together, and the piles are vertical or inclined foundation members arranged in the soil and act to pass through a soft high-compressibility soil layer or water, so that the load born by the piles is transferred to a harder, denser or less-compressibility foundation bearing layer, and the piles in the pile foundation are generally called foundation piles.
The improvement of the pile foundation on the bearing performance is mainly in two aspects of pile side friction resistance and pile end resistance, wherein the improvement of the pile end resistance is most remarkable in the improvement of the bearing performance of the pile foundation. The foundation pile is a pile type which is used for compacting a pile hole bearing layer or soil body (comprising additional filler) in the pile, and can be a rigid pile or a flexible pile. Representative pile types are carrier piles and compaction piles.
The compaction pile is to fill in pile holes and to compact the pile body in layers to form a compact pile body with high strength, and the compaction process can be applied to the pile end only or along the pile hole, so that the soil body of the hole wall is compacted further by radial expansion of compacted materials, and meanwhile, the soil between the piles and the soil of the pile body are tightly cemented together. When only tamping the pile end, the compaction pile has extremely high pile end bearing performance, and concrete can be cast in place on the compaction pile; when the pile hole is filled by long ramming, the compaction pile has both great pile end bearing performance and pile side friction resistance, so that the integral single pile bearing performance of the compaction pile can be greatly improved, and the compaction pile can be used as a composite foundation during pile group construction.
The carrier pile consists of an upper pile body and a lower composite carrier, wherein the pile body is generally of a cast-in-place concrete structure or a high-strength prestressed pipe pile, and the composite carrier is a composite body which is positioned at the bottom of the pile body and is tamped by deep filling materials, so that the stress of the pile end can be diffused and reduced layer by layer, the bearing capacity of the foundation soil body of the pile end is fully mobilized, and the bearing capacity of the pile is greatly improved.
Along with the continuous development of construction technology of building engineering, in the foundation pile construction mainly based on dynamic compaction packing, a standardized and automatic operation mode is introduced, and the construction efficiency and the construction quality are greatly improved.
For example, in chinese patent publication No. CN113322928A, an automatic pile body non-soil compaction type carrier pile multi-equipment high-efficiency construction method is disclosed, which can monitor a ramming settlement of a rammer in real time and automatically determine and execute a next process, such as filling or ramming; thus, the automatic ramming control of the rammer and the automatic quantitative feeding of the filling material can be realized, and the standardized and automatic operation of the carrier pile can be realized.
For example, in chinese patent publication No. CN113481962a, a method for automatically constructing deep dynamic compaction composite foundation is disclosed, and related parameters of compaction judgment of a rammer after compacting a filler are further refined, and even if soil compactness detection is performed in an automatic compaction process, the method can also be automatically performed, so that the automatic construction control logic of related piles like carrier piles and compaction piles is more perfect.
In the chinese patent with application number CN2023108795896, an intelligent in-pipe carrier construction method and a digital construction method are also disclosed, wherein a reference pile hole is formed at a sampling hole in the geological survey, the lifting hammer height obtained by the pile hole ramming is used as the ramming height of the rest of the implemented pile holes, and the ramming height is input into an automatic pile foundation construction device for automatic construction by combining with a preset ramming threshold value and a standard quantity of single automatic filling, so that the construction efficiency and construction quality of pile groups in the same single area can be greatly reduced; in the whole construction process, key construction parameter data are stored and uploaded to a server, so that traceability of foundation pile construction parameters can be realized, on-line monitoring of construction quality can be realized, and the automatic construction technology of the pile foundation is combined fully.
However, with the development of construction technologies of foundation piles with high bearing capacity such as carrier piles and compaction piles, and continuous research and improvement of automatic pile foundation construction equipment, in a large number of construction projects, a large number of key construction parameters can be and have been accumulated, and how to reasonably and fully utilize these data to promote the intelligent development of foundation pile construction is a problem to be solved.

Detailed Description
The following description of the embodiments of the present application will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the invention are shown. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
At present, in the construction of foundation piles, particularly compaction piles, carrier piles and other foundation piles with high bearing capacity, the commonality is that the original soil layer or the additional filling quantity in the pile holes is compacted into an enlarged body at the pile bottom, the compactness of the soil layer at the bearing layer of the pile bottom can be obviously increased, the bearing performance of the pile end is improved, the construction equipment is mostly conventional pile foundation equipment, the construction process is that the operator participates more in the construction process by ramming a heavy hammer in the pile holes through a high-rise portal crane, and the construction method is the current situation in the construction of the foundation piles at present.
Although some automatic pile foundation construction equipment capable of automatically lifting hammers, tamping and throwing fillers and automatically detecting relevant construction parameters in construction is disclosed in the related art, for example, in China patent with publication number of CN114991144A, the automatic construction equipment for carrier piles is disclosed, can realize the functions, realize the automatic operation of foundation pile construction, accurately control the amount of fillers and other relevant key parameters, can realize standardized operation in foundation pile construction, and has great benefits for quality control of foundation pile construction. However, the cost of such automated equipment is increased compared to conventional portal pile foundation equipment, and some relevant control parameters also need to be determined by construction experience of constructors, so that further development of further advantages of the automated pile foundation construction equipment is still required for popularization and popularization of the automated pile foundation construction equipment.
The embodiment of the application discloses a foundation pile construction method based on big data. Referring to fig. 1, the foundation pile construction method based on big data includes the steps of:
s1, acquiring historical foundation data and historical construction data of foundation pile construction, and establishing a database; specifically, when a database is built, on one hand, the data recorded by the existing pile foundation construction equipment during foundation pile construction can be uploaded manually or automatically to obtain the data, and on the other hand, the related data registered in a construction record table in the past construction project can be recorded to obtain the data.
S2, building a construction task and acquiring current basic data of the construction task; in this embodiment, the current base data and the historical base data differ only in occurrence time, and specific meanings are not different, so they are collectively referred to as base data hereinafter to facilitate explanation of the scheme of the present application. The basic data includes, but is not limited to, design parameters, soil layer property parameters, bearing layer soil moisture content and bearing layer soil load bearing performance parameters.
It should be noted that, the design parameters include, but are not limited to, pile top elevation, pile bottom elevation, site elevation, hole depth, hole diameter, pile length, single pile bearing capacity, etc., where the single pile bearing capacity is a key indicator.
The soil layer property parameters, the bearing stratum soil body moisture content and the bearing stratum soil body bearing performance parameters are collectively called as geological parameters, can be read and recorded in a geological survey report before each construction, can also be accessed into a data platform or a database comprising the related geological survey data, and can be searched and called by means of the coordinates of a target construction site.
S3, according to the current basic data, screening historical construction data corresponding to the historical basic data closest to the current basic data from a database. When the data are compared and screened in the database, the similarity weight of the historical basic data and the current basic data is sequentially from large to small as design parameters, bearing performance parameters of the bearing layer soil body, the water content of the bearing layer soil body and soil layer property parameters, wherein the design parameters mainly compare key indexes, namely the bearing capacity of the design single pile when compared.
In addition, in the present embodiment, the current construction data and the history construction data differ only in occurrence time, and specific meanings are not different, so that the construction data will be hereinafter collectively referred to as construction data for convenience in explaining the scheme of the present application. And the corresponding basic data and construction data together form a data set, and are stored in a database. The historical construction data and the current construction data comprise, but are not limited to, a compaction test threshold value, standard quantity of single automatic filling, lifting hammer height, total number of times of ramming by a heavy hammer when the filling material is compacted and reaches the standard, filling times, total filling quantity, construction duration and the like.
Specifically, the compaction testing threshold is used for representing the compaction degree of the standard quantity of filling material by compaction, and different setting values are provided under different soil layer properties, and the significance of setting is as follows: when the difference between the pile bottom elevation and the pile bottom elevation falls into the tamper checking threshold after the hammer strikes, the pile foundation construction equipment starts automatic filling, namely the tamper checking threshold can be used as a trigger filling threshold. For example, when compaction pile construction is carried out, the standard requirement of soil body in the compaction process is not high, and when the compression modulus of the soil layer at the periphery of the pile bottom elevation is smaller than 10Mpa, the compaction test threshold value can be-5 to-50 cm; when the compression modulus of the soil layer at the periphery of the pile bottom elevation is more than or equal to 10Mpa, the compaction testing threshold value can be 5-50 cm. When the carrier pile is constructed, the control precision requirement of the compactness of the filler in the compaction process is higher, so that when the compression modulus of the soil layer at the periphery of the pile bottom elevation is less than 10Mpa, the compaction test threshold value can be-5 cm to-20 cm; when the compression modulus of the soil layer at the periphery of the pile bottom elevation is more than or equal to 10Mpa, the compaction testing threshold value can be 5-20 cm.
On the other hand, before the automatic construction of the pile foundation construction equipment is started, the lifting hammer height needs to be determined, and when the lifting hammer height is determined in the tamping testing process, the tamping testing threshold value is also used as an important index for judging whether the lifting hammer height reaches a required value. Specifically, the elevation of the bottom of the heavy hammer after being rammed is defined as a first-click elevation, and the first-click elevation is subtracted from the elevation of the pile bottom to obtain a first-click standard difference; if the first impact standard deviation is smaller than the minimum value of the tamping threshold, increasing the lifting hammer height and then lifting the heavy hammer for tamping; if the first impact standard deviation is larger than the maximum value of the tamping threshold, reducing the lifting hammer height and lifting the heavy hammer for tamping; if the standard deviation accords with the tamper detection threshold range, the current lifting hammer height accords with the requirement. Therefore, the tamping testing threshold can influence the automatic filling time and the lifting height of the pile foundation construction equipment, and is an important index which must be clear before the automatic construction of the pile foundation construction equipment.
In specific operation, the tamper testing threshold value in the initial historical construction data in the database is formulated by the construction experience of constructors based on the value range; the tamper threshold value in the historical construction data retrieved from the database is determined from the data recorded in the database.
Similarly, the initial value of the standard quantity of the single automatic filling and the parameter of the lifting hammer height is corrected and formulated by the construction experience of constructors and the tamping inspection process, and the value of the parameter in the subsequent construction is determined by the data recorded in the database.
S4, outputting the acquired historical construction data to pile foundation construction equipment for automatic construction; the pile foundation construction equipment is required to have at least the following functions: the automatic lifting device can automatically lift the heavy hammer to a specified height and freely drop the heavy hammer, automatically convey a filling quantity of a specified quantity, detect the elevation of the bottom surface of the heavy cone or the elevation difference of the bottom of the heavy hammer when the heavy hammer falls down twice adjacently in real time, and record, store and upload construction data such as the lifting height, single feeding quantity, the penetration of the heavy hammer, the elevation of the bottom of the heavy hammer and the like.
S5, acquiring current basic data and current construction data after the construction task is completed, and updating a database, in particular adding a data set in the database.
Therefore, based on the related construction data record in the stock foundation pile construction project and the continuous operation of the automatic pile foundation construction equipment in the construction site, the historical basic data and the historical construction data stored in the database can reach a considerable level, the related data stored in the database can provide automatic construction parameter basis for foundation pile construction in each pile position as the most basic utilization of the construction data, the dependence on the construction experience of constructors in foundation pile construction is reduced as much as possible, and the construction quality is improved.
Meanwhile, the design quantity of foundation piles per 1000 square meters of the foundation reaches hundreds, along with the continuous increase of the magnitude of the database, the parameter basis provided by the historical data in the database is more accurate, and the foundation pile foundation construction method can even replace construction technicians to a certain extent, so that the specific data in foundation pile construction is utilized in a database mode, and the foundation pile construction method has a wide development prospect and good popularization advantage.
Specifically, for example, when the carrier pile is constructed, according to the design requirement of the current basic data, the historical construction data corresponding to the historical basic data of one pile hole with the highest similarity of the current basic data is screened out from the database, and the automatic pile foundation construction equipment can download the historical construction data from the machine as the current construction data and match the current basic data to form a new data set.
When the automatic pile foundation construction equipment executes an operation instruction generated based on the current construction data, the initial height of a hoisting hammer of a winch module of the automatic pile foundation construction equipment can be obtained through the parameter of the lifting hammer height; the initial lifting hammer height can be accurately corrected and the starting of an automatic filling module can be controlled through the judgment of the tamping testing threshold value; the amount of material fed to each automatic filling module can be set by the parameters of the standard amount of single automatic filling. Therefore, the preparation work of the tamping testing stage can be greatly reduced, the tamping testing time is shortened, the tamping testing precision can be greatly improved by means of the related parameters provided by big data, the number of times of manual correction of automatic pile foundation construction equipment in the process of automatically executing operation instructions is reduced as much as possible, and the construction efficiency is improved.
The total number of times of ramming the heavy hammer and the number of times of filling when the filling material is compacted and reaches the standard in the historical construction data are used as data references in the construction process; the reason is that the basis of the judgment of the piling of the carrier pile is three-click penetration detection, and the three data can represent the time when the compacted filling material in the pile hole can reach the detection of the three-click penetration; when the automatic pile foundation construction equipment reaches any parameter index in the automatic operation process, the three-stroke penetration degree detection can be performed, the condition that uninterrupted tamper test is needed in the past construction to judge the accurate time of the three-stroke penetration degree detection is effectively improved, and the construction efficiency can be remarkably improved.
Moreover, the data set stored in the database is a combination of the foundation data and the construction data which are strongly corresponding, namely, the construction control requirements corresponding to the foundation data are matched according to objective requirements such as design parameters, geological parameters and the like, so that the construction method is not only limited to the construction of known pile types such as carrier piles, compaction piles (including deep dynamic compaction composite foundations) and rammed and expanded piles, but also can provide construction basis for foundation pile construction similar to soil compaction or foundation construction, even if the construction method does not need piling and only needs to meet the set bearing requirements.
In addition, pile forming spot check is generally performed after pile group construction to determine whether the constructed pile foundation meets the design requirement, so that a data set corresponding to the pile foundation with qualified quality after spot check has more representative significance.
Therefore, in other possible embodiments, if pile foundation bearing performance detection is performed on the pile foundation after the construction task is completed, generally, pile foundation static load experiments and low strain detection are adopted, then the current basic data further includes pile foundation detection parameters, such as load weight, settlement amount in unit time and low strain waveform judgment conclusion; when the historical construction data is screened in the database, the historical basic data containing the detection parameters are preferentially compared, and only the relevant historical basic data with qualified pile foundation bearing performance detection is screened, so that the value of a data set screened in the database can be ensured as much as possible, and more accurate construction basis is provided for the construction of the later pile foundation.
Similarly, in the process that the automatic pile foundation construction equipment receives an operation instruction generated based on current construction data to perform automatic construction, if abnormal conditions such as broken soil, rubber soil and the like occur in the tamping process of the heavy hammer, the abnormal conditions are difficult to effectively solve only through the determination of the tamping threshold value and the determination of the control of the tamping of the heavy hammer in the related construction method, and at the moment, manual intervention such as remote control equipment of technicians or field debugging equipment of constructors is needed.
Thus, in other possible embodiments, the historical construction data and the current construction data also each include the weight deflection and correction parameters for manually correcting the construction equipment when the deflection is abnormal; the correction parameters include, but are not limited to, several shots of the device subside before the device is implanted with the correction parameters, correction of the height of the jack, correction of the number of fills of the automatic filling module.
