Description

Technical Field

[0001] The invention relates to the technical field of casting quality control, and in particular to a T-beam casting construction risk control method. Background Art

[0002] In bridge engineering, T-beams are widely made of concrete as load-bearing components, so their casting quality is crucial. In the casting process of T-beams, it is usually necessary to cast them in layers multiple times. After each layer of concrete is cast, a vibrator must be used to expel the bubbles in the concrete to ensure quality before the next layer can be constructed. This places strict requirements on the height of each layer of concrete: if the height is too high, the bubbles cannot be completely expelled, affecting the quality of the T-beam; if the height is too low, the number of castings will increase and the construction time will be extended.

[0003] The traditional pouring method usually involves moving a concrete mixer truck along the T-beam while pouring. However, this method has several risks and shortcomings. First, it is difficult to accurately control the speed and discharge of the mixer truck, resulting in uneven pouring. Second, there is a lack of effective monitoring methods during the construction process. Once problems such as blockage occur, it is difficult to detect and solve them in time, which in turn affects the overall construction efficiency. These problems may have an adverse impact on the quality of the T-beam and the construction progress. Summary of the invention

[0004] The present invention provides a T-beam casting construction risk control method, which can effectively solve the problems of uneven casting and lack of monitoring in the existing T-beam casting method in the background technology.

[0022] S70: Determine whether the remaining amount of concrete is sufficient for the next pouring. If so, return to S30, and the pouring direction is opposite to the previous pouring; if not, issue an alarm, and return to S10 after replacing the transport vehicle.

[0060] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0061] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0062] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] The present invention relates to a T-beam casting construction risk control method, using Figure 1~2 The risk control system for T-beam casting construction shown includes:

[0064] The mobile platform 1 moves along the pouring direction; a slope 5 can be preferably provided on the side of the mobile platform 1 for the transport vehicle to go up and down;

[0065] A bracket 2 is arranged on the mobile platform 1;

[0066] A material distribution component is fixedly arranged on the bracket 2, capable of receiving concrete output from the transport vehicle and transferring it to the outside for distribution of concrete pouring;

[0067] The first weighing device 3 is arranged on the mobile platform 1 and is used to detect the weight of the transport vehicle, and the data unit at the detection location is kg;

[0068] The second weighing device 4 is arranged on the mobile platform 1 and is used to detect the weight of the fabric assembly, and the data unit at the detection point is kg.

[0069] The working process of this system is as follows: before pouring, the transport vehicle will drive to the first weighing device 3 on the mobile platform 1, and then start to output concrete to the material distribution component; then the mobile platform 1 starts to move, and by collecting the data of the first weighing device 3 and the second weighing device 4, the control module can calculate the travel speed of the mobile platform 1 accordingly, so that the poured concrete can be more uniform and the pouring amount can be more accurate. After the pouring of each layer is completed, the remaining amount of concrete in the transport vehicle will be measured by the first weighing device 3. If the remaining amount is not enough for the next pouring, an alarm will be issued and a new transport vehicle will be replaced. At this time, new parameters need to be input through the operation display panel to ensure that the subsequent pouring process meets the construction requirements of the concrete in the new transport vehicle. During the pouring process, the data of the first weighing device 3 and the second weighing device 4 can also be used to monitor in real time whether the material distribution component is blocked, and an alarm can be issued in time when it is blocked.

[0070] Based on the above control system, the specific steps of the control method are proposed below, including:

[0071] S10: Detect the slump slu of the concrete to be poured. The slump slu is an indicator that reflects the fluidity of concrete and can be used to estimate the transportation conditions of the concrete.

[0072] S20: Divide the pouring section into three sections along the length direction, and number them one, two, and three according to the pouring direction, and record the theoretical demand of each section as ML1, ML2, and ML3, respectively, all in kg; when pouring starts, read the detection data of the first weighing device 3 as M0 (in kg), and the detection data of the second weighing device 4 as m0 (in kg), M0 is the total weight of the transport vehicle and the concrete loaded thereon when pouring starts, and m0 is the total weight of the distribution assembly and the concrete loaded thereon when pouring starts.

[0073] S30: During the pouring process, the detection data of the first weighing device 3 and the second weighing device 4 are read once every set time, and recorded as M1, M2, ..., M respectively. q (Unit: kg) and m1, m2...m q (Unit: kg); and calculate the average feeding efficiency navg through the recorded detection data, so that the average feeding efficiency navg becomes a real-time updated value; during the pouring process, every time a navg appears, it is necessary to judge whether navg is within the set range, usually whether navg is greater than a set minimum value. If it is smaller than the set minimum value, it means that a certain blockage may have occurred, resulting in its inability to discharge materials normally, and it is necessary to stop pouring and issue a blockage alarm.

[0074] S40: Calculate the theoretical feeding efficiency n0 and the theoretical travel speed S1 according to SLU, control the pouring platform to move forward according to the speed of S1, and perform the pouring of the first section.

[0075] S50: At the end of the first stage of pouring, the first weighing device 3 detects data Mt1, and the second weighing device 4 detects data mt1. Mt1 is the total weight of the transport vehicle and the concrete loaded thereon at the end of the first stage of pouring, and mt1 is the total weight of the material distribution assembly and the concrete loaded thereon at the end of the first stage of pouring. At this point, the weight of the concrete poured at the end of the first stage of pouring, Me1, can be calculated:

[0076] First, calculate M0-Mt1. This value is the weight of concrete output from the transport vehicle at the end of the first pouring. Then calculate m0-mt1. This value is the weight of the concrete in the distribution component at the end of the first pouring compared to the beginning. If it is a positive value, it means that the concrete retained in the distribution component is also taken out with this pouring. If it is a negative value, it means that a part of the concrete is retained in the distribution component during this pouring. At this time, add the two together through M0-Mt1+(m0-mt1) to calculate the final weight of the concrete poured into the formwork, that is, Me1.

[0077] Then determine the difference between the first section cast weight Me1= M0-Mt1+(m0-mt1) and ML1;

[0078] If the difference is not within the set range, an alarm will be issued;

[0079] If the difference is within the set range, record the average feeding efficiency navg at this time as navg2, calculate the second section travel speed S2, and then control the pouring platform to move forward according to the speed of S2 to carry out the pouring of the second section.

[0080] S60: When the second section is poured, the detection data of the first weighing device 3 is read as Mt2, and the detection data of the second weighing device 4 is read as mt2. The weight of the second section poured Me2 can be calculated in the same way as Me1; then the weight of the second section poured Me2=the difference between M0-Mt2+(m0-mt2) and ML1+ML2 is determined;

[0081] If the difference is not within the set range, an alarm will be issued;

[0082] If the difference is within the set range, record the average feeding efficiency navg at this time as navg3, calculate the third section travel speed S3, and then control the pouring platform to move forward according to the speed of S3 to carry out the pouring of the third section.

[0083] S70: Determine whether the remaining amount of concrete is sufficient for the next pouring. If so, return to S30, and the pouring direction is opposite to that of the previous pouring, so that the mobile platform 1 can pour back and forth along the length direction of the T-beam during the entire T-beam pouring process; if not, an insufficient remainder alarm is issued, and after replacing the transport vehicle, return to S10, that is, the slump slu of the concrete to be poured in the new transport vehicle needs to be remeasured.

[0084] In the preferred step S30, the specific calculation model of the average feeding efficiency navg is:

[0085] Each time the detection data of the first weighing device 3 and the second weighing device 4 are recorded, △M is calculated once. q and △m q , △M q Used to reflect the weight of concrete delivered by the transport truck, △m q Used to reflect the weight of concrete remaining in the cloth component, specifically:

[0086] When recording the detection data of the first weighing device 3 and the second weighing device 4 for the qth time, calculate △M q =M q -M q-1 and △m q =m q-1 -m q.

[0087] Then the ratio of concrete input and output in the q segment can be regarded as the instantaneous efficiency at this time point, and the instantaneous efficiency n can be calculated. q =(△M q -△m q ) / △M q .

[0088] With the instantaneous efficiency at each time point, the overall average feeding efficiency navg can be calculated:

[0089] When q is less than 5, the pouring has just started and the amount of data is small, so we only need to simply calculate the average value, navg=(n1+n2+……+n q ) / q;

[0090] When q≥5, the amount of data increases, and there may be a large difference between the early data and the later data, which will affect the calculation of the average value. Therefore, it is necessary to remove the early data and only calculate the average value of the latest data to avoid excessive errors, that is, navg=(n q-4 +n q-3 +n q-2 +n q-1 +n q ) / 5.

[0091] In the preferred step S40, the specific calculation model of the theoretical feeding efficiency n0 is:

[0092] n0=k·slu a ;

[0093] Among them, k and a are both set empirical constants.

[0094] In the preferred step S40, the specific calculation model (including the derivation process) of the theoretical traveling speed S1 is:

[0095] First, it is assumed that when pouring this layer, the material can be fed according to the theoretical feeding efficiency n0, and the theoretical material distribution component transmission volume per unit time Md0=Mb·n0 is calculated;

[0096] It can be deduced that the theoretical output volume of the cloth component per unit time is vd0=Md0 / p=Mb·n0 / p;

[0097] By comparing the total volume to be poured with the output volume per unit time, the total time required for this pouring can be calculated theoretically. ;

[0098] The final theoretical moving speed S1 of the mobile platform 1 (in m / min) is:

[0099] ;

[0100] Among them, Mb is the output of the transport vehicle per unit time, in kg / min; p is the density of concrete, in kg / m 3 ; V is the total volume to be poured, in m 3 ; L is the total length to be poured, in m.

[0101] In the preferred step S50, the specific calculation model (including the derivation process) of the second travel speed S2 is:

[0102] At this point, the first section of the material laying construction has been completed, and the actual feeding efficiency of the material laying component can be calculated, that is, the average feeding efficiency navg. The average feeding efficiency navg at this time is read as the feeding efficiency navg2 of the second section. Then, the actual material laying component transmission volume per unit time Md2=Mb·navg2 can be calculated when pouring the second section.

[0103] Then when pouring the second section, the actual output volume of the distribution component per unit time is vd2=Md2 / p=Mb·navg2 / p.

[0104] The theoretical time required for pouring the second section is T2:

[0105] ;

[0106] Then the basic travel speed S2 can be calculated by S2=l2 / T2. On this basis, since the feeding efficiency during the first section of pouring uses the expected value n0, the first section of the poured beam may be too much or too little compared to the expected value, so this situation needs to be taken into account, that is, it is necessary to calculate again:

[0107] Calculate the poured weight of the first section after pouring: Me1 = M0-Mt1+(m0-mt1);

[0108] Calculate the theoretical required pouring volume of the first section Mn1=l1·V / (L·p);

[0109] Then the travel speed S2 of the mobile platform 1 during pouring the second section can be calculated as:

[0110] ;

[0111] After substituting the above formula into the above formula, we get:

[0112] ;

[0113] Among them, l1 is the length of the first segment, in m; l2 is the length of the second segment, in m; b is the artificially set proportional coefficient.

[0114] l2 / T2 is the basic speed calculated according to navg2. Now we introduce To adjust it: If the first section is poured less, that is, Me1<Mt1, then will be less than 1, making the travel speed S2 slower relative to the base speed, so that more concrete can be poured in the middle section to make up for the less poured in the first section; if more concrete is poured in the first section, that is, Me1>Mt1, then It will be greater than 1, causing the travel speed S2 to increase relative to the basic speed, thereby reducing the amount of concrete poured in the middle section to balance the excess amount poured in the first section.

[0115] In step S60, the specific calculation model (including the derivation process) of the third segment travel speed S3 is:

[0116] When pouring the third section, it is necessary to determine the actual amount of pouring required, and then use this as a basis to calculate the travel speed S3, as follows:

[0117] Calculate the poured weight of the second section after pouring: Me2 = M0-Mt2+(m0-mt2);

[0118] Calculate the required pouring weight Mn3=V / p-Me2 after the second section is poured;

[0119] Through the newly obtained navg3, the actual transmission volume per unit time Md3 = Mb·navg3 during pouring of the third section can be calculated;

[0120] Then the theoretical time required for pouring the third section is T3=Mn3 / Md3;

[0121] Then we can calculate the travel speed of the mobile platform 1 during the pouring of the third section: S3 = l3·Mb·navg3 / Mn3;

[0122] Wherein, l3 is the length of the third segment, in meters.

[0123] The electrical structure in the risk control system of T beam casting construction Figure 3 As shown, it also includes:

[0124] A calculation module, used to collect detection data of the first weighing device 3 and the second weighing device 4, calculate whether a blockage problem occurs, and calculate the moving speed of the mobile platform 1;

[0125] The verification module is used to verify the feasibility of the calculation results of the calculation module to prevent the calculated results from being unrealizable or the speed change from being too large to threaten the safety of pouring. When the verification fails, an alarm needs to be issued in a timely manner;

[0126] A control module, used to control the moving speed of the mobile platform 1 according to the calculation result of the calculation module;

[0127] The operation display panel is connected to the control module and is used for personnel to input the parameters required for each pouring, and to display the control parameters, equipment status and other data calculated by the control module;

[0128] The alarm module is connected to the control module and is used to send out an alarm.

[0129] Preferably, a remote communication module is also provided in the T-beam casting construction risk control system. The remote communication module is connected to the calculation module and is used to receive remote information and send data remotely, so that the dispatching center can remotely learn about and modify the on-site construction work, or when a risk point occurs, the dispatching center can receive an alarm in the first time.

[0130] When the transport vehicle is outputting concrete, there will be differences in its output at different time points. This difference is the main reason for the uneven discharge of concrete. Therefore, the concrete output by the transport vehicle cannot be directly poured into the formwork. In this T-beam casting construction risk control system, the material distribution assembly includes two feeding screw feeders 6. This screw feeder feeds material through spiral blades, which can ensure the stability of the discharge amount, thereby solving the problem of uneven discharge. The feeding screw feeders 6 are preferably arranged symmetrically on both sides of the mobile platform 1, so that the transport vehicle can drive onto the mobile platform 1 from a more convenient direction.

[0131] In the T-beam casting construction risk control system, it is preferred that the material distribution assembly also includes a discharging screw feeder 7, which is arranged between the two loading screw feeders 6. The two loading screw feeders 6 first transport the concrete to the discharging screw feeder 7, and then the discharging screw feeder 7 outputs the concrete to the outside. The discharging screw feeder 7 is used to keep the discharging position of the material distribution assembly fixed at all times, so as to better control the casting process.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
