Description

Technical Field

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

[0002] With the development of building information technology (BIT), the measurement of ready-mixed concrete is crucial for ensuring project quality. Currently, the measurement of ready-mixed concrete on construction sites mainly relies on indirect methods such as factory-direct measurement and weighing at the construction site. These methods often result in discrepancies between the actual volume of concrete pumped and poured, leading to disputes over which measurement result should be used and causing numerous issues in volume settlement. Furthermore, the informatization of concrete pumping is still at the stage of simply installing some video surveillance on-site, lacking a real-time location-based pumping measurement method. Therefore, it is impossible to view and control the real-time volume and pumping points of concrete pumped on-site, which is also a significant factor limiting the development of smart construction sites. Summary of the Invention

[0003] To more accurately measure the actual amount of concrete used on the construction site and improve the management efficiency and digitalization of pouring construction, this invention provides a concrete pumping metering system and construction method.

[0004] The technical solution of the concrete pumping metering system of the present invention is as follows:

[0005] A concrete pumping metering system includes a computer system and a metering trolley and a barcode scanning device connected to the computer system via signals; the metering trolley and the barcode scanning device are configured in a one-to-one correspondence; the computer system includes a database, the database includes pouring records, and the fields of the pouring records include metering trolley number, pouring volume, pump truck number, mixer truck number, transport volume, and completion status.

[0006] The present invention discloses a concrete pumping metering system. In use: First, pump trucks equipped with QR codes (each QR code containing pump truck information) are placed at various pouring points on the construction site, and a concrete pumping metering system is installed accordingly. Then, when the mixer truck enters the construction site and reaches the designated pouring point, a scanning device scans both the pump truck's QR code and the QR code carrying the mixer truck driver, which contains transport information. The pump truck number, mixer truck number, transport volume, and the metering trolley number corresponding to the scanning device are linked together to form a pouring record, which is then stored in a database. The completion status of the pouring record is changed to "Transporting". Next, the pump truck and the mixer truck are connected via a metering trolley. The pump truck is started, pumping the concrete from the mixer truck to the pouring point, and the pouring volume is recorded via the metering trolley. After the concrete pumping is completed, the pouring volume is recorded in the pouring record, and the completion status of the pouring record is changed to "Pending Verification". Finally, the transported volume and the poured volume in the pouring record are compared. If the preset conditions are met, the completion status of the pouring record is changed to "Verification Normal". If the preset conditions are not met, the completion status of the pouring record is changed to "Verification Abnormal". When the completion status is "Verification Abnormal", the staff will verify the concrete transport work.

[0007] The concrete pumping metering system of the present invention has the following technical effects:

[0008] First, by directly measuring the amount of concrete poured on-site using a metering cart, 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.

[0009] Second, by comparing the amount transported by the mixer truck with the amount directly measured by the metering trolley during the on-site material feeding process, and conducting a difference analysis, it is possible to more directly determine whether there is any leakage or shortage of concrete, thus achieving clear traceability of the responsible party.

[0010] Furthermore, the concrete pumping and metering system also includes a cloud system, with the computer systems of each concrete pumping and metering system connected to the cloud system. During the pouring process, pouring records can be uploaded to the cloud system in real time. The cloud system can centrally manage the data uploaded by each concrete pumping and metering system, thereby improving the management level of the pouring construction. The cloud system can also associate the location information of each pump truck with the pouring point, laying the foundation for realizing the digitalization and visualization of on-site concrete metering, pumping, and pouring, and improving the intelligence level of on-site concrete construction management.

[0011] Furthermore, the concrete pumping metering system also includes a human-machine interface (HMI). The HMI displays data from the database in the computer system and confirms information obtained from barcode scanning. The HMI is located on the metering cart, mobile phone, and computer. The HMI and the computer system of the metering cart are linked in real-time to achieve real-time information transmission. Additionally, the HMI's backend management allows for on-demand allocation of functions. That is, the display functions and content of the HMI on each metering cart, mobile phone, and computer can be differentiated. Some operations can be assigned to specific personnel in each project, with different permissions set according to the project management level, displaying different interfaces to adapt to different projects and improve equipment operation reliability and feasibility. For example, the HMI on the metering cart, facing the operator, can display pouring records and allow the operator to confirm information obtained from barcode scanning; while the HMIs on the mobile phone and computer only display pouring records, facilitating management personnel to view construction progress.

[0012] Furthermore, in the concrete pumping metering system, the metering trolley includes a support frame, a conveyor belt mounted on the support frame, a drive system for driving the conveyor belt, barriers on both sides of the conveyor belt, a weighing sensor at the bottom of the conveyor belt, and a discharge hopper fixed to the upper part of the conveyor belt by a funnel bracket. The drive system includes a drive motor, a drive wheel mounted on the output shaft of the drive motor, a transmission wheel coaxially rotating with the rollers of the conveyor belt, and a transmission belt connecting the drive wheel and the transmission wheel. The rollers drive the feeding belt of the conveyor belt. The mixer truck pours concrete into the discharge hopper of the metering trolley; then, the concrete is weighed on the feeding belt by the weighing sensor and simultaneously transported to the pump truck.

[0013] This invention also provides a construction method for a concrete pumping metering system, the technical solution of which includes the following steps:

[0014] S1, pump trucks with QR codes are set up at each pouring point on the construction site, and a concrete pumping metering system is also set up.

[0015] S2, after the concrete mixer truck enters the construction site and arrives at the designated pouring point, a barcode scanner is used to scan the QR code on the pump truck and the QR code carrying the concrete mixer truck driver, which contains transportation information. The pump truck number, concrete mixer truck number, transportation quantity, and the metering trolley number corresponding to the barcode scanner are linked together to form a pouring record, which is then stored in the database. The completion status of the pouring record is then changed to "transporting".

[0016] S3, connect the pump truck and the mixer truck through the metering trolley; start the pump truck to pump the concrete on the mixer truck to the pouring point, and record the pouring volume through the metering trolley; after the concrete is pumped, record the pouring volume in the pouring record, and change the completion status of the pouring record to "waiting for verification";

[0017] S4. Compare the transport volume and the pouring volume in the pouring record; if the preset conditions are met, change the completion status of the pouring record to "verification normal"; if the preset conditions are not met, change the completion status of the pouring record to "verification abnormal".

[0018] The construction method of the concrete pumping metering system of the present invention has the following technical effects:

[0019] First, by directly measuring the amount of concrete poured on-site using a metering cart, 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.

[0020] Second, by comparing the amount transported by the mixer truck with the amount directly measured by the metering trolley during the on-site material feeding process, and conducting a difference analysis, it is possible to more directly determine whether there is any leakage or shortage of concrete, thus achieving clear traceability of the responsible party.

[0021] Furthermore, the construction method of the concrete pumping metering system also includes S5, where the pouring records of each concrete pumping metering system can be uploaded to the cloud system in real time. The cloud system can uniformly manage the data uploaded by each concrete pumping metering system, thereby improving the management level of pouring construction. The cloud system can also associate the location information of each pump truck with the pouring point, laying the foundation for realizing the digitalization and visualization of on-site concrete metering, pumping, and pouring, and improving the intelligence level of on-site concrete construction management.

[0022] Furthermore, in the construction method of the concrete pumping metering system, specifically, S4 also includes the following: the preset condition is 80% * delivery volume <= pouring volume <= 120% * delivery volume. Attached Figure Description
