Description

Technical Field

[0001] This invention belongs to the field of digital construction engineering, and specifically relates to a concrete metering system and digital construction method for construction sites. Background Technology

[0002] With the emergence of smart construction sites and intelligent construction, the digitalization of building construction is of paramount importance. Digitalized concrete metering and pumping at construction sites serves as a crucial link connecting the digitalization of concrete delivery from the plant to the pumping and pouring stage, laying a foundation for the subsequent digitalization of the entire building lifecycle. Furthermore, digitalized construction effectively improves construction efficiency and management levels, and is a significant manifestation of green construction.

[0003] Currently, in the complex environment of construction sites, the measurement of concrete entering the site mainly adopts factory measurement and weighbridge measurement methods. Theoretically, this is not the final concrete pumping volume. Due to various reasons, there is a certain deviation between the factory measurement of concrete and the amount of concrete forming the project entity, resulting in inconsistencies in measurement during settlement. Moreover, concrete pumping and pouring is a process with high-density manual participation, and the measurement and statistics of volume are also manually intervened, making it difficult to trace the source of responsibility and manage. Therefore, there is an urgent need to study a digital construction method for accurate measurement and pumping at construction sites. Summary of the Invention

[0004] To more accurately measure the actual amount of concrete used on construction sites and improve the management efficiency and digitalization of pouring construction, this invention provides a concrete metering system and digital construction method for construction sites.

[0005] The technical solution of the concrete metering system for construction sites according to the present invention is as follows:

[0006] A concrete metering system for construction sites includes a computer system, several pump trucks, several metering devices, and concrete mixer trucks. The pump trucks are fixed at various pouring points on the construction site. The computer system is signal-connected to each pump truck, metering device, and concrete mixer truck. The computer system includes a pouring information database and an arrival information database. The pouring information database includes pouring records, the fields of which include pouring point number, pump truck number, metering device number, vehicle number, concrete pouring volume, and completion status. The arrival information database includes arrival records, the fields of which include vehicle number, transport volume, and current status.

[0007] This invention discloses a concrete metering system for construction sites. In use, firstly, pump trucks are deployed at various pouring points on the construction site. Then, concrete mixer trucks enter the construction site and reach the designated pouring points, connecting to the pump trucks via metering equipment. The computer system records the vehicle number and transport volume of the concrete mixer truck, forming an entry record, which is then stored in the entry information database. The current status of this entry record is then changed to "transporting". Next, the concrete in the concrete mixer truck is pumped to the pouring point, and the metering equipment calculates the concrete volume. After pumping at this pouring point is completed, the computer system records the pouring point number, pump truck number, metering equipment number, vehicle number, and concrete volume, forming a pouring record, which is then stored in the pouring information database. The completion status of this pouring record is then changed to "no". If necessary, the concrete mixer truck moves to the next pouring point, repeating the above pumping process until the concrete mixer truck completes its transport work. Finally, the computer system changes the current status of the entry record with the vehicle number of the current concrete mixer truck in the entry information database to "awaiting verification." The computer system then compares the sum of the concrete pouring volumes (V1) of the pouring records with the same vehicle number and a completion status of "No" in the pouring information database with the transport volume (V2) of the entry record with the same vehicle number and a current status of "awaiting verification." If the preset conditions are met, the completion status of the pouring record with the same vehicle number and a completion status of "No" in the pouring information database is changed to "Yes," and the current status of the entry record with the same vehicle number in the entry information database is changed to "verification normal." If the preset conditions are not met, the current status of the entry record with the same vehicle number in the entry information database is changed to "verification abnormal." Staff will then verify the concrete transport work performed in this instance.

[0008] The concrete metering system for construction sites of the present invention has the following technical effects:

[0009] First, by directly measuring the concrete delivery volume of the concrete mixer truck using metering equipment, the impact of various objective factors during concrete transportation on the measurement of concrete pouring volume is reduced, thereby improving the accuracy of concrete pouring volume measurement.

[0010] Second, because the concrete metering system at the construction site records data from the pump truck, metering equipment, and concrete mixer truck during each pumping operation, and the records can be categorized and statistically analyzed as needed, the concrete pouring process at the construction site can be managed more flexibly, thereby improving the work efficiency of the construction site.

[0011] Third, the on-site concrete metering system can save and query metering and pouring location information, which can more directly restore the actual use of concrete on site, and make responsibility traceable, thereby avoiding concrete metering disputes.

[0012] Fourth, by connecting concrete mixer trucks and pump trucks through metering equipment and computer systems, digital management of the entire process of concrete from leaving the factory to being pumped to the construction site is realized, which is conducive to the supervision and control of concrete quality.

[0013] Furthermore, in the aforementioned concrete metering system at a construction site, a barcode scanner is installed on the metering equipment; the pump truck and concrete mixer truck include barcodes that can be recognized by the scanner. After the pump truck, metering equipment, and concrete mixer truck are in place, the scanner scans the barcodes on the pump truck and concrete mixer truck to associate information such as the pouring point number, pump truck number, metering equipment number, vehicle number, and concrete pouring volume during a single pumping operation. This simplifies the process of the computer system recording pouring and arrival records, improving on-site construction efficiency. Alternatively, information can be associated through manual input. The scanner can also be set up independently. The barcode on the concrete mixer truck can be carried by the driver, and the barcode information may also include the production date, manufacturing date, and pouring location. If the computer system 1 needs to access this information, the corresponding fields need to be set in the database.

[0014] Furthermore, in the aforementioned construction site concrete metering system, the computer system also includes a visual linkage model; the visual linkage model displays the pouring status of each pouring point in real time. The visual linkage model can display the location distribution and pouring status of each pouring point in real time. Based on the pouring data of each pouring point, the construction progress of concrete pouring across the entire construction site can be assessed, thereby estimating concrete demand and achieving precise procurement; it can also be used as a basis for optimizing and adjusting the distribution of pouring points, improving construction efficiency.

[0015] Furthermore, in the aforementioned concrete metering system for construction sites, the computer system also includes a report generation module. This module can generate statistical reports as needed, thereby improving material management efficiency.

[0016] Furthermore, in the aforementioned on-site concrete metering system, the metering equipment includes a conveyor belt speed sensor, a concrete weight sensor, and a concrete flow sensor. The coordination of these sensors can improve the accuracy of concrete pouring volume measurement.

[0017] Furthermore, in the aforementioned construction site concrete metering system, specifically, the fields of the pouring records in the pouring information database also include concrete temperature; and the fields of the entry records in the entry information database also include batching plant code, concrete strength grade, and pouring location.

[0018] This invention also provides a digital construction method for concrete metering at construction sites, the technical solution of which includes the following steps:

[0019] S1, pump trucks are deployed at various pouring points on the construction site;

[0020] S2. After the concrete mixer truck enters the construction site, it arrives at the preset pouring point and is connected to the pump truck through the metering equipment. The computer system records the vehicle number and transport volume of the concrete mixer truck, forming an entry record, and stores the entry record in the entry information database. Then, the current status of the entry record is changed to "transporting".

[0021] S3, pump the concrete from the concrete mixer truck to the pouring point and calculate the concrete pouring volume using the metering equipment; after the pumping of this pouring point is completed, the computer system records the pouring point number, pump truck number, metering equipment number, vehicle number, and concrete pouring volume in this pumping, forming a pouring record, and stores the pouring record in the pouring information database. Then, the completion status of the pouring record is changed to "No".

[0022] S4, the concrete mixer truck moves to the next pouring point, repeat S3, until the concrete mixer truck completes the transportation work;

[0023] S5, the computer system changes the current status of the entry record with the vehicle number of the current concrete mixer truck in the entry information database to "awaiting verification"; the computer system compares the sum of the concrete pouring volumes (V1) of the pouring records with the vehicle number of the current concrete mixer truck in the pouring information database and a completion status of "No" with the transport volume (V2) of the entry record with the vehicle number of the current concrete mixer truck in the entry information database and a current status of "awaiting verification"; if the preset conditions are met, the completion status of the pouring record with the vehicle number of the current concrete mixer truck in the pouring information database is changed to "Yes", and the current status of the entry record with the vehicle number of the current concrete mixer truck in the entry information database is changed to "verification normal"; if the preset conditions are not met, the current status of the entry record with the vehicle number of the current concrete mixer truck in the entry information database is changed to "verification abnormal".

[0024] The digital construction method for concrete metering at construction sites according to the present invention has the following technical effects:

[0025] First, by directly measuring the concrete delivery volume of the concrete mixer truck using metering equipment, the impact of various objective factors during concrete transportation on the measurement of concrete pouring volume is reduced, thereby improving the accuracy of concrete pouring volume measurement.

[0026] Second, because the concrete metering system at the construction site records data from the pump truck, metering equipment, and concrete mixer truck during each pumping operation, and the records can be categorized and statistically analyzed as needed, the concrete pouring process at the construction site can be managed more flexibly, thereby improving the work efficiency of the construction site.

[0027] Third, the on-site concrete metering system can save and query metering and pouring location information, making responsibility traceable and thus avoiding concrete metering disputes.

[0028] Fourth, by connecting the concrete mixer truck and pump truck through metering equipment and computer system 1, the entire process of concrete pumping from the factory to the construction site is digitally managed, which is conducive to the supervision and control of concrete quality.

[0029] Furthermore, in the digital construction method for concrete metering at the construction site, specifically, S1 also includes associating the pump truck number of each pump truck with the pouring point number of each corresponding pouring point in the computer system.

[0030] Furthermore, in the digital construction method for concrete metering at the construction site, specifically in S5, a confirmation button is set on the metering device. After the confirmation button is clicked, the computer system changes the current status of the entry record of the current concrete mixer truck with the vehicle number in the entry information database to "awaiting verification".

[0031] Furthermore, in the digital construction method for concrete metering at the construction site, specifically, S5 also includes the preset condition that 80%*V2<=V1<=120%*V2. Attached Figure Description

After pumping at this pouring point is completed, computer system 1 records the pouring point number, pump truck number, metering device number, vehicle number, and concrete volume, creating a pouring record, which is then stored in the pouring information database 11.

[0056] First, by directly measuring the concrete delivery volume of the concrete mixer truck 4 through the metering equipment 3, the influence of various objective factors on the measurement of concrete pouring volume during the concrete transportation process is reduced, thereby improving the accuracy of concrete pouring volume measurement.

[0057] Second, because the concrete metering system at the construction site records the data information of the pump truck 2, metering equipment 3, and concrete mixer truck 4 during each pumping operation, and the records can be classified and statistically analyzed as needed, the concrete pouring process at the construction site can be managed more flexibly, thereby improving the work efficiency of the construction site.

[0058] Third, the on-site concrete metering system can save and query metering and pouring location information, making responsibility traceable and thus avoiding concrete metering disputes.

[0063] Example 3:

[0064] This example provides a processing flow of the computer system 1:

[0065] The initial structure of the pouring information database 11 is:

[0066]

[0067] The structure of the entry information database 12 is:

[0068] serial number Vehicle number Shipping volume Current status

[0069] The pump truck numbers of each pump truck 2 are associated with the pouring point numbers of the corresponding pouring points. After the association, the associated pump truck numbers and pouring point numbers will be recorded in one pouring record.

[0070] First, after the concrete mixer truck 4 enters the construction site and arrives at the preset pouring point (Point 1), the concrete mixer truck 4 is scanned using the scanning device 5. The computer system 1 records the vehicle number (Shanghai A12345) and the delivery volume (30 tons) of the concrete mixer truck 4, forms an entry record, and stores the entry record in the entry information database 12. Then, the current status of this entry record is modified to "in transit". At this time, the entry information database 12 is updated as:

[0078] serial number Vehicle number Shipping volume Current status 1 Shanghai A12345 30 tons Waiting for verification

[0079] The computer system 1 compares the sum value (V1 = 29 tons) of the volumes of the poured concrete in the pouring records with the vehicle number of Shanghai A12345 and the completion status of "no" in the pouring information database 11 with the transportation volume (V2 = 30 tons) in the entry record with the vehicle number of Shanghai A12345 and the current status of "awaiting verification" in the entry information database 12; if it meets the preset conditions (such as V2 - V1 < 2 tons), then the completion status of the pouring records with the vehicle number of Shanghai A12345 and the completion status of "no" in the pouring information database 11 is modified to "yes". At this time, the pouring information database 11 is updated to:

[0080]

[0081] And change the current status of the entry record of the vehicle with vehicle number Shanghai A12345 in the entry information database 12 to "verification normal"; at this time, the entry information database 12 is updated to:

[0082] serial number Vehicle number Shipping volume Current status 1 Shanghai A12345 30 tons Verification successful

[0083] If the preset conditions are not met (such as V2 - V1 < 0.5 tons), then change the current status of the entry record of the vehicle with the vehicle number of the current concrete mixer truck 4 in the entry information database 12 to "verification abnormal". At this time, the entry information database 12 is updated to:

[0084] serial number Vehicle number Shipping volume Current status 1 Shanghai A12345 30 tons Verification error

[0085] The pouring information database 11 is not updated, and the staff will check the concrete transportation work with abnormal verification.

Any changes and modifications made by those of ordinary skill in the art based on the above disclosure shall fall within the scope of protection of the claims.
