Description

Concrete mixing plant control method, computer device and computer readable storage medium

Technical Field

The invention relates to the field of progress control of building construction, and particularly provides a concrete mixing plant control method, a computer device for implementing the method and a computer readable storage medium.

Background

The construction needs to use a large amount of concrete, because the concrete is very easily concreted after producing, consequently need pour into in the certain time after concrete production finishes, if do not pour into for a long time, will lead to the concrete to set and can't pour into, lead to the extravagant condition of concrete. On the other hand, during the construction, since some large buildings need to be poured for a long time, for example, the pile hole has a large volume, the pouring needs to be performed for a long time, and the pouring is not allowed to be interrupted, if the pouring is interrupted, the poured concrete is caused to be solidified, and the newly poured concrete and the poured concrete cannot be combined, which easily causes the quality problem of the pile.

For the construction of pile holes, a plurality of procedures such as pile hole drilling, hole forming detection and reporting, steel reinforcement cage and pipe installation, hole cleaning and reporting, and concrete pouring are generally required, but each procedure requires a certain time, for example, pile hole drilling generally requires 8 hours, hole forming detection and reporting generally requires 1 hour, steel reinforcement cage and pipe installation generally requires 4 hours, hole cleaning and reporting generally requires 3 hours, and concrete pouring generally requires 4 hours, so the time from the beginning of drilling to concrete pouring is long, the time of each procedure is an estimated time, in the actual construction process, the time of each procedure can change according to the actual construction condition, if concrete production is carried out too early, concrete coagulation is caused, and waste is caused, and if the concrete production time is too late, the progress of pile hole pouring is influenced, for the pile hole with larger volume, if the production time of concrete is too late, the problem of discontinuous concrete pouring can be caused, and the pouring quality of the pile is influenced.

In addition, the volume of concrete actually required to be poured into the pile hole is dynamically changed, and once the volume of concrete required to be poured is insufficient, the volume of concrete needs to be supplemented, that is, the concrete needs to be supplemented and produced, but after the concrete is produced, the concrete needs to be transported to a construction site through a concrete truck, and the production and transportation of the concrete takes a certain time.

Generally, the pile hole construction waiting pouring time is too long, and the pouring continuity is poor, mainly because the waiting time and the square repairing time of concrete are both long, which directly results in poor construction quality of the pile hole. Specifically, the initiation of the concrete pouring requirement and the arrival time of commercial concrete are long, and the concrete pouring time is influenced by the initiation, production queuing, transportation and other time of the concrete pouring requirement.

Therefore, the chinese patent application with publication number CN103660034A discloses a tubular pile concrete mixing plant and a control method, the method collects the single-pile concrete requirement of each tubular pile position and the host concrete capacity of a mixing host, calculates the total amount of concrete required for all tubular pile positions according to the single-pile concrete requirement of each tubular pile position, then compares the single-pile concrete requirement of each tubular pile position with the host concrete capacity respectively to obtain a first comparison result, and compares the total amount of concrete required for all tubular pile positions with the host concrete capacity to obtain a second comparison result; and finally, determining the production mode of the tubular pile concrete mixing plant according to the first comparison result and the second comparison result, and producing according to the determined production mode.

However, the method is suitable for a scene with a clear concrete demand, and only suitable for a situation that the mixing plant is located at a working site, and does not consider the situation that the mixing plant is located at a certain distance from a construction site, namely the influence of the calculation time of the concrete on the production of the concrete. In addition, the method does not distinguish the situations of the pile hole which can be noticed immediately and the pile hole which can be poured after a period of time, and the main reason of the discontinuous concrete pouring or the waste of the concrete is that the demand of the pile hole which can be poured after a period of time is not clear enough, if the volume of the concrete for ordering is too much, the waste of the concrete is caused, if the concrete for ordering is too little, the prescription is required to be continuously supplemented, and once the prescription is supplemented, the discontinuous pouring and the hard pouring quality are caused.

Disclosure of Invention

A first object of the present invention is to provide a control method of a concrete mixing plant capable of avoiding waste of concrete and effectively ensuring continuous supply of concrete.

The second purpose of the invention is to provide a computer device for realizing the control method of the concrete mixing plant.

A third object of the present invention is to provide a computer-readable storage medium for implementing the above-mentioned concrete batching plant control method.

In order to achieve the first purpose of the invention, the concrete mixing plant control method provided by the invention comprises the steps of obtaining information of a first pile hole which can be poured currently, and calculating a first pouring amount of the first pile hole; acquiring information of a second pile hole which can be poured within the target prediction time, calculating the total pouring amount of the second pile hole, and calculating a second pouring amount of the second pile hole, wherein the second pouring amount is a preset proportion of the total pouring amount of the second pile hole; and calculating the planned production of the planned concrete according to the first pouring amount, the second pouring amount and the waiting pouring amount.

According to the scheme, the first pouring amount of the first pile hole which can be poured immediately is calculated, the total pouring amount of the second pile hole which can be poured after a period of time is calculated, and the second pouring amount is calculated according to a certain proportion, so that the current planned production amount is calculated, on one hand, the waste of concrete caused by excessive concrete volume of a next pile can be avoided, on the other hand, when the second pile hole can be poured, enough concrete can be poured, and the pouring continuity is ensured.

Preferably, the planned throughput is the first filled volume plus the second filled volume minus the waiting filled volume.

Therefore, the concrete pouring waiting amount is the volume of the produced concrete in the calculation process, and the concrete is poured after a period of time, so that the calculation method can avoid waste of the produced concrete and can calculate the demand of the concrete more accurately.

Further, the target prediction time is between 1.5 hours and 2.5 hours, and preferably, the target prediction time is 2 hours.

Because the production and transportation time of the concrete is about 2 hours generally, the supply of the concrete can be ensured to be continuous and stable by setting a reasonable target prediction time.

In a further embodiment, the second filling amount is 70% to 90% of the total filling amount of the second pile hole, and preferably, the second filling amount is 80% of the total filling amount of the second pile hole.

Because the hole cleaning time of the pile hole is influenced by various factors and cannot be finished within the preset time, the second pouring amount is calculated according to a certain proportion, and the problem of excessive concrete volume of the lower pile can be avoided. On the other hand, in order to avoid long-time waiting, the second pouring amount is set to be 80% of the total pouring amount of the second pile hole, so that the pouring of the pile hole can be started in a short time after the hole cleaning is finished, and the pouring efficiency is improved.

The further scheme is that the pouring amount of the concrete truck to the pile hole is obtained, and when the concrete truck is poured, the pouring amount of the concrete truck is subtracted from the pouring amount to obtain a new pouring amount.

Therefore, the accuracy of the finally calculated planned production can be ensured and the waste of concrete can be avoided by dynamically and real-timely updating the waiting pouring amount.

The concrete truck filling method comprises the following steps of obtaining the residual quantity of the concrete truck after the concrete truck is filled, and adding the residual quantity of the concrete truck to the waiting filling quantity to obtain a new waiting filling quantity if the residual quantity of the concrete truck exceeds a threshold value.

Therefore, if the concrete truck does not pour all the concrete into the pile hole, the residual quantity can be poured into other pile holes again, and therefore the residual quantity needs to be calculated as the pouring waiting quantity, waste of the concrete can be avoided, and calculation accuracy of the planned production quantity is also ensured.

Preferably, before calculating the planned production capacity, it is determined that the sum of the number of the first pile holes and the number of the second pile holes exceeds two.

Because only one pile hole needs to be poured, coordination does not need to be carried out, and a construction unit can determine the required amount of concrete according to the current actual situation, the planned production amount of the concrete is calculated only when the number of the pile holes to be poured is large.

In order to achieve the second object, the present invention provides a computer device comprising a processor and a memory, wherein the memory stores a computer program, and the computer program realizes the steps of the concrete mixing plant control method when being executed by the processor.

To achieve the third objective, the present invention provides a computer readable storage medium having a computer program stored thereon, where the computer program is executed by a processor to implement the steps of the control method for a concrete mixing plant.

The invention is further explained with reference to the drawings and the embodiments.

Detailed Description

The control method of the concrete mixing plant is applied to the mixing plant for producing the concrete, the mixing plant is arranged at a position with a certain distance from a pile hole construction site, and the concrete produced by the mixing plant needs to be transported to the pile hole construction site through a concrete truck. In particular, the invention is applied to a control server of a mixing plant, the server is provided with a processor and a memory, and the memory is stored with a computer readable storage medium, and when the processor executes the computer readable storage medium, the concrete mixing plant control method can be realized.

The concrete mixing plant control method comprises the following steps:

the embodiment is applied to a mixing plant for controlling the production of concrete in the mixing plant, and particularly, the planned production capacity of the mixing plant can be calculated by applying the control method for the mixing plant, so that the waste of concrete caused by excessive production capacity of concrete is avoided, and the overlong waiting time for filling pile holes caused by too little production capacity of concrete is also avoided.

In the pile hole construction process, a construction unit sends an instruction for producing concrete to a concrete mixing plant according to the requirement of an actual construction progress, for example, placing orders to the concrete mixing plant, wherein each order contains the square amount of the concrete to be produced. For more accurate required concrete volume of calculation, this embodiment divides the stake hole into two types of stake holes according to the construction progress in stake hole, and first type stake hole is the stake hole that can carry out the pouring at once, and second type stake hole is the stake hole that can just carry out the pouring after needing to wait for a period of time.

The construction of the pile hole involves multiple processes of pile hole drilling, hole forming detection and reporting, steel reinforcement cage and conduit installation, hole cleaning and reporting, concrete pouring and the like, and each process needs a certain time, for example, the pile hole drilling usually needs 8 hours, the hole forming detection and reporting usually needs 1 hour, the steel reinforcement cage and conduit installation usually needs 4 hours, the hole cleaning and reporting usually needs 3 hours, the concrete pouring usually needs 4 hours, and the concrete mixing plant usually needs 2 hours from receiving an order and producing the concrete to transporting to a construction site, so according to the construction progress, the first type of pile hole is the pile hole which is cleaned or is about to be cleaned, the second type of pile hole is the pile hole which is started to be cleaned, and the hole cleaning time is about 1 hour. It will be appreciated that the second pile hole is a pile hole that can be grouted within a target predicted time, which may be 1.5 hours to 2.5 hours, preferably 2 hours.

In this embodiment, the first type of pile hole is referred to as a first pile hole, the second type of pile hole is referred to as a second pile hole, and generally, the number of the first pile hole and the second pile hole is multiple, that is, a construction unit generally needs to pour a plurality of pile holes to form a plurality of pipe piles.

The operation of the present embodiment will be described with reference to fig. 1. Firstly, step S11 is executed to determine whether the number of pile holes to be poured exceeds 2, that is, whether the sum of the number of first pile holes and the number of second pile holes exceeds 2, if the number of pile holes to be poured is small, the planned production amount of concrete is not directly calculated in a manual calculation manner, that is, step S12 is executed, the construction unit directly calculates the currently required concrete volume according to the construction requirement, and the concrete mixing plant directly produces the required concrete according to the next volume.

If the number of the pile holes to be poured currently exceeds two, step S13 is executed to obtain the information of the first pile hole and count the number of the first pile hole. Specifically, after the number of the first pile holes is counted, the pouring amount of the first pile holes is calculated. Since the first pile hole is determined, the volume of concrete needed by each pile hole is also determined, so that the volume of concrete needed by a plurality of first pile holes can be calculated, that is, the first pouring volume is obtained through calculation.

Then, step S14 is executed to obtain information of the second hole and count the number of the second stake holes. Specifically, after the number of the second pile holes is counted, the total pouring amount of the second pile holes is calculated. Since the second pile hole is determined, the concrete volume required for each pile hole is also determined, so that the concrete volume required for a plurality of second pile holes can be calculated. However, since the second pile hole is not cleaned and the hole cleaning time is uncertain, if the concrete volume required by the second pile hole is produced completely, the concrete is wasted, and therefore, the total pouring amount of the second pile hole needs to be multiplied by a preset coefficient to obtain the second pouring amount of the second pile hole for concrete production. In this embodiment, the second filling amount is 80% of the total filling amount of the second pile hole, that is, step S15 is performed. Ordering in this manner ensures that there is an adequate supply of concrete for a period of time, for example 2 hours, that there are continuous concrete cars at the pile hole construction site and that the waiting time for each car does not exceed the setting time of the concrete.

Then, step S16 is performed to calculate the planned production volume based on the first perfusion volume, the second perfusion volume, and the waiting perfusion volume. In this embodiment, the amount to be poured is also referred to as an amount in transit, and is the amount to be poured after the concrete mixing plant produces concrete and transports the concrete to the construction site after the planning of the construction unit, and the amount of concrete leaving the mixing plant but not poured into the pile hole is the amount to be poured. And as the pouring of the pile hole is completed, the waiting pouring amount is reduced.

In step S16, the calculated planned production amount is the first pouring amount plus the second pouring amount minus the waiting pouring amount, that is, the planned production amount is the first pouring amount plus the second pouring amount minus the waiting pouring amount, and after the planned production amount is determined, the concrete mixing plant will produce the required concrete according to the planned production amount. It should be noted that, if a certain pile hole is completely poured, the pile hole is no longer the first pile hole, and the corresponding first pouring amount is also changed. Of course, as the hole cleaning work is performed, the number of the second pile holes is also changed, for example, after the hole cleaning of the second pile holes is completed, the second pile holes become the first pile holes, and if a new pile hole is cleaned for 1 hour, the second pile holes become new second pile holes. Therefore, it is necessary to dynamically update the planned production amount by calculating the first and second pouring amounts from the conditions of the first and second pile holes.

In the process of pile hole construction, concrete is continuously poured into the pile hole, so that the waiting pouring amount is dynamically updated, the waiting pouring amount needs to be dynamically updated, step S17 needs to be executed to judge whether the waiting pouring amount is updated, if yes, step S18 is executed to calculate the planned production amount by using the updated waiting pouring amount.

Referring to fig. 2, when the filling amount waiting is updated, step S21 is first executed to obtain the current filling amount waiting, and step S22 is executed to determine whether there is a concrete truck waiting to be filled, for example, a concrete truck is performing a weighing operation. Specifically, after the concrete truck arrives at a construction site, the pouring amount of concrete of the concrete truck which is available immediately can be determined, after the pouring is completed, namely, the concrete carried by the concrete truck is poured into the designated pile hole, and meanwhile, the pouring amount is reduced, and the corresponding first pouring amount is also reduced. Therefore, when the concrete truck is over weight, that is, the concrete truck is considered to be ready to pour concrete into the designated pile hole, step S23 is executed to wait for the poured amount to be subtracted by the square amount of concrete carried by the concrete truck.

Of course, if the concrete truck does not fill all the concrete trucks into the designated pile holes, for example, the remaining amount is large and called back weight, the step S24 needs to be executed to determine whether the remaining amount of the concrete truck exceeds the threshold, if not, the concrete truck is considered to have very little concrete remaining, the back weight square amount may not be calculated, if the threshold is exceeded, the step S25 is executed to add the waiting filling amount to the remaining amount of the concrete truck to obtain a new waiting filling amount, that is, the step S26 is executed to obtain an updated waiting filling amount.

This embodiment divides into first stake hole and second stake hole according to the construction progress in stake hole to calculate required concrete square volume according to the certain proportion in second stake hole, can let the mixing plant produce certain concrete in advance on the one hand, ensure going on in succession that the stake hole is bored concrete, on the other hand avoids again leading to the extravagant condition of concrete to take place because of the required whole concretes of whole production second stake holes.
