The delivery of components is not synchronized with the construction progress, which will cause resource waste and cost increase for both parties. In actual engineering projects, changes in the construction progress often occur due to many factors such as construction conditions, design changes, and weather, which in turn affects the delivery time of components.

[0061] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0062] Example 1

[0063] like Figure 1 As shown, a beam yard prefabrication plan making system based on erection working surface time includes:

[0064] The module for calculating the erection sequence of each beam is used to calculate the erection start time and erection end time of each span beam according to the deadline of the erection working surface and the erection efficiency, and then calculate the erection start time and erection end time of each beam according to the erection start time and erection end time of each span beam, and obtain the erection sequence of each beam according to the erection start time and erection end time of each beam;

[0065] The dynamic prefabrication efficiency calculation module for each beam is used to obtain the remaining prefabrication days of the beam yard according to the time relationship between the current date, the start date of prefabrication in the beam yard, and the end date of prefabrication in the beam yard, and then calculate the dynamic prefabrication efficiency of each beam according to the number of remaining unprefabricated beams, the remaining prefabrication days of the beam yard, and the standard prefabrication period of each beam;

[0066] A calculation module for the start date and end date of prefabrication of each beam, which is used to calculate the start date and end date of prefabrication of each beam according to the erection start time of each span beam, the dynamic prefabrication efficiency of each beam and the erection sequence of each beam;

[0067] The module for formulating the periodic prefabrication plan for each beam span is used to formulate the start date and end date of the periodic prefabrication plan for each beam span according to the start date and end date of prefabrication of each beam, and calculate the average prefabrication efficiency of the periodic prefabrication plan for each beam span, and then calculate the corresponding cumulative efficiency according to the start date of the periodic prefabrication plan for each beam span, and compare the average prefabrication efficiency of the periodic prefabrication plan for each beam span with the corresponding cumulative efficiency to judge the rationality of the periodic prefabrication plan for each beam span. If the periodic prefabrication plan for a certain beam span is unreasonable, the periodic plan for that beam span will be reformulated until it is judged to be reasonable.

[0068] like Figure 2 and Figure 5 As shown, it is a schematic diagram of the distribution of the spans and span beams of the bridge of the present invention. The quantity units of the beams of the entire bridge are divided into spans and beams, and one span is composed of L beams.

[0069] (1) In the module for calculating the erection sequence of each beam, the erection start time and the erection end time of each span of beams are calculated according to the deadline of the erection working surface and the erection efficiency, and then the erection start time and the erection end time of each span of beams are calculated according to the erection start time and the erection end time of each span of beams. The specific method is as follows:

[0070] First, according to the deadline of each erection work surface Calculate the X value of each beam span s Erection start time and erection end time

[0071]

[0072] In the formula, N is the cutoff number of the span, E1 is the erection efficiency of the working face, and s is the span number;

[0073] Then, according to the erection sequence and erection start time of each span beam, Calculate each beam X s,b The start time of the installation and erection end time The calculation formula is as follows:

[0074]

[0075] In the formula, L is the number of frames in each span, and b is the serial number of the frame in the sth span of the beam.

[0076] This step is to reverse the erection date of each beam according to the erection work surface node, and automatically determine the prefabrication production order of each beam according to the principle of "whoever is erected first will prefabricate first". Arranging the prefabrication production order of each beam according to the erection work surface node is the most practical order for construction, and is the basis for ensuring that the delivery of components matches the construction progress, thus making the final beam yard prefabrication plan more accurate.

[0077] (2) In the dynamic prefabrication efficiency calculation module for each beam, the remaining prefabrication days of the beam yard are obtained according to the time relationship between the current date, the start date of prefabrication at the beam yard, and the end date of prefabrication at the beam yard. Then, according to the number of remaining unprefabricated beams, the remaining prefabrication days of the beam yard, and the standard prefabrication period of each beam, the specific method for calculating the dynamic prefabrication efficiency of each beam is as follows:

[0078] According to the current date T 当 , Beam prefabrication start date Beam prefabrication end date Calculate the remaining prefabrication days T in the beam yard X , the calculation formula is as follows:

[0079]

[0080] Then according to the number of remaining unprefabricated beams B N , The remaining prefabrication days in the beam yard T X , Standard prefabrication period for each beam T 榀,标 , the dynamic prefabrication efficiency E2 of each beam is calculated, and the calculation formula is as follows:

[0081] E2=(B N ) / (T X -T 榀,标 +1).

[0082] The dynamic prefabrication efficiency of each beam is calculated based on the number of remaining unprefabricated beams, and the prefabrication plan can be adjusted dynamically, ensuring the flexibility of the prefabrication plan at the beam yard.

[0083] (3) Figure 3 As shown, in the calculation module for the start date and end date of prefabrication of each beam, the specific method for calculating the start date and end date of prefabrication of each beam is as follows according to the erection start time of each span beam, the dynamic prefabrication efficiency of each beam and the erection sequence of each beam:

[0084] The precast start date of the bth frame of the sth span of the beam is T s,b,预制开始 The calculation formula is as follows:

[0085]

[0086] Among them, [] means round down, T s s X for each span beam s Erection start time;

[0087] The precast completion date of the bth frame of the sth span of the beam is T s,b,预制结束 The calculation formula is as follows:

[0088] T s,b,预制结束 (X s,b )=T s,b,预制开始 (X s,b )+T 榀,标

[0089] The prefabrication start event and prefabrication end time of each beam are calculated based on the dynamic prefabrication efficiency of each beam, which ensures the flexibility of the prefabrication start event and prefabrication end time of each beam.

[0090] (4) Figure 4As shown, in the per-span beam period prefabrication plan formulation module, the start date and end date of the per-span beam period prefabrication plan are formulated according to the start date and end date of prefabrication of each beam, and the average prefabrication efficiency of the per-span beam period prefabrication plan is calculated, and then the corresponding cumulative efficiency is calculated according to the start date of the per-span beam period prefabrication plan, and the average prefabrication efficiency of the per-span beam period prefabrication plan is compared with the corresponding cumulative efficiency. The specific method for judging the rationality of the per-span beam period prefabrication plan is as follows:

[0091] The start and end dates of each periodic prefabrication plan are determined according to the start date and end date of each prefabrication of each beam, and the average efficiency of each periodic prefabrication plan is compared with the cumulative efficiency. If the average efficiency E5 of the periodic prefabrication plan is less than or equal to the cumulative efficiency E6, the periodic prefabrication plan is considered reasonable, otherwise it is considered unreasonable. The formula is as follows:

[0092] E5=B1 / (T 周期,结束 -T 周期,开始 )

[0093]

[0094]

[0095] T 周期,开始 Pre-plan the start date for the cycle, T 周期,结束 is the end date of the periodic prefabrication plan, B1 is the number of prefabricated beams planned in the periodic prefabrication plan, and B N is the number of remaining unprefabricated beams, M is the starting number of the span, N is the ending number of the span, L is the number of beams in each span, and (NM)*L is the total number of beams.

[0096] The start and end dates of each period prefabrication plan are formulated according to the start date and end date of prefabrication of each beam. Therefore, the formulated prefabrication plan for each period must match the prefabrication time of each beam. In theory, this avoids the situation where the plan cannot be completed during the actual prefabrication process due to the plan being formulated in advance.

[0098] In addition to the contents included in Example 1, the dynamic prefabrication efficiency calculation module for each beam is also used to calculate the prefabrication efficiency of the beam when production constraints occur; the prefabrication start date and end date calculation module for each beam is also used to calculate the prefabrication start date and end date of each beam when production constraints occur based on the erection start time of each span of beams, the prefabrication efficiency of the beam when production constraints occur, and the erection order of each beam.

[0099] The dynamic prefabrication efficiency calculation module for each beam is also used to calculate the prefabrication efficiency of the beam when production restriction conditions occur. The specific method is as follows:

[0100]

[0101] E4=(B N -(T 限终 -T 限起 )*E3) / (T X -T 榀,标 -(T 限终 -T 限起 )+1)

[0102] Among them, E4 represents the prefabrication efficiency of each beam during the erection period of each span, excluding the production restriction period, and E3 represents the prefabrication efficiency of each beam during the production restriction period. E3 is calculated in real time based on the actual situation. 限起 is the start time of the production restriction period, T 限终 is the end time of the production restriction period, is the start time of erection of the s-span beam, The erection completion time of the sth span beam.

[0103] The module for calculating the start date and end date of prefabrication of each beam is also used to calculate the start date and end date of prefabrication of each beam when production restriction conditions occur according to the erection start time of each span beam, the prefabrication efficiency of the beam when production restriction conditions occur, and the erection sequence of each beam. The specific method is as follows:

[0104] Considering the influence of the actual prefabrication production restriction period, calculate the prefabrication start date T of the sth span and the bth frame of the beam when the production is restricted s,b,预制开始,限制 :

[0105]

[0106] Among them, [] means round down, T 限制,开始 Indicates the start time of the production restriction period, T 限制,结束 N1 represents the time from the start of the erection of the s-th span beam to the start of the production restriction period T 限制,开始 N2 represents the number of prefabricated beams at the time of production restriction. 限制,开始 Until the end time of the production restriction period T 限制,结束 N3 is the number of prefabricated beams, and N4 is the time when the erection of each span of the beam is completed. Number of prefabricated beams;

[0107] The prefabrication completion date T of the bth frame of the sth span of the beam under production constraints s,b,预制结束,限制 The calculation formula is as follows:

[0108] T s,b,预制结束,限制 (X s,b )=T s,b预制开始,限制(X s,b )+T 榀,标 .

[0109] This step takes into account the constraints that may arise during the actual production process, such as holidays, machine failures, etc., which may result in the inability to operate at full capacity, thereby improving the adaptability of the prefabrication plan.

[0110] Example 3

[0113] According to the time relationship between the current date, the start date of beam yard prefabrication, and the end date of beam yard prefabrication, the remaining days for prefabrication in the beam yard are obtained. Then, according to the number of remaining unprefabricated beams, the remaining days for prefabrication in the beam yard, and the standard prefabrication period of each beam, the dynamic prefabrication efficiency of each beam is calculated.

[0124] This step is to reverse the erection date of each beam according to the erection work surface node, and automatically determine the prefabrication production order of each beam according to the principle of "whoever is erected first will prefabricate first". Arranging the prefabrication production order of each beam according to the erection work surface node is the most practical order for construction, and is the basis for ensuring that the delivery of components matches the construction progress, thus making the final beam yard prefabrication plan more accurate.

[0135] The precast completion date of the bth frame of the sth span of the beam is T s,b,预制结束 The calculation formula is as follows:

[0136] T s,b,预制结束 (X s,b )=T s,b,预制开始 (X s,b )+T 榀,标

[0144] The start and end dates of each period prefabrication plan are formulated according to the start date and end date of prefabrication of each beam. Therefore, the formulated prefabrication plan for each period must match the prefabrication time of each beam. In theory, this avoids the situation where the plan cannot be completed during the actual prefabrication process due to the plan being formulated in advance.

E3 is calculated in real time based on the actual situation. 限起 is the start time of the production restriction period, T 限终 is the end time of the production restriction period, is the start time of erection of the s-span beam, The erection completion time of the sth span beam.

[0151] The specific method for calculating the start date and end date of prefabrication of each beam when production restriction conditions occur is as follows based on the erection start time of each span beam, the prefabrication efficiency of the beams when production restriction conditions occur, and the erection order of each beam:

[0152] Considering the influence of the actual prefabrication production restriction period, calculate the prefabrication start date T of the sth span and the bth frame of the beam when the production is restricted s,b,预制开始,限制 :
