Description
Technical Field
The invention belongs to the technical field of computer simulation, relates to a simulation modeling method, and particularly relates to a simulation modeling method for a two-bin combined pouring system of a high arch dam.
Background
The high arch dam is mostly positioned in the mountain and gorge region, the topography is rugged, the topography is narrow, and in addition, due to the consideration of the dam growth and construction requirements, the arrangement of the concrete mixing plant is positioned on a higher elevation platform, so that the cable machine becomes a main warehousing machine. And when the cable machine transports concrete, the hanging tank is filled on the material taking platform, and then the links such as lifting of the full tank of the trolley, translation of the trolley, descending of the full tank of the trolley, unloading of the bin surface and the like are used for realizing the concrete transportation process, and the time consumption of each link forms the time consumption of the cable machine circulation. Different cable machine distance of transport and hanging depth make cable machine circulation time different to make cable machine concrete warehouse entry intensity different.
Along with the rise of the pouring elevation of the arch dam, the number of the castable dam sections is increased, the area of the bin surface is gradually reduced, and double bins or multiple bins can be adopted for simultaneous pouring. And the movement of a cart of the cable machine is reduced during pouring, the utilization rate of the cable machine is improved, the cable machine is scientifically scheduled, the bins are reasonably arranged, and the large bin surface and the small bin surface are matched, and the far bin surface and the near bin surface are matched. When the unfavorable working conditions of simultaneous casting of adjacent or closer bin surfaces occur, unified command of staff is firstly obeyed, sequential casting is adopted, the cable machine can be relatively fixed to be responsible for casting the defined strips, the flat bin of the flat bin machine is fully utilized, and the strength of the cable machine for hoisting concrete to enter the bin is improved on the premise of ensuring the safe operation of the cable machine.
The running track of the cable machine circulates between the charging point and the discharging point of the two-to-be-poured bin noodle strips during two-bin combined pouring, is more complex than single-bin pouring, and also improves the difficulty of preparing a bin surface partition scheme. The running track and sequence of the cable machine in the two-bin combined pouring process and the single-bin pouring process are greatly different, and when the two bins are combined pouring, the interference before the adjacent cable machine is not negligible. If the interference of adjacent cable machines is not considered completely when the simulation analysis of the cabin surface partition construction scheme is carried out, the simulation result of the concrete warehousing strength of the actual cable machine for hoisting concrete is higher than the actual value, and the simulation precision is affected. Through retrieval, the simulation of the casting process of the high arch dam bin surface is not carried out by a cable machine under the working condition of combined casting of two bins in the prior art.

and carrying out statistical analysis on construction parameters of each procedure by adopting a exploratory statistical analysis method on pouring bin data.
The concrete storage strength of the cable machine depends on the single circulation time of the cable machine, and the single circulation time of the cable machine depends on the transportation distance and the transportation height of the cable machine.
Two cabin surfaces of a certain high arch dam 13# -018 and 18# -026 are poured to serve as simulation cases of simulation modeling of a two cabin combined pouring system, and a 5# cable machine is used for hoisting part of concrete quantity on the two cabin surfaces. 13-018 is sequentially laid from downstream to upstream according to strips, 18-026 is sequentially laid from upstream to downstream according to strips, after the first blank layer of the 18-026 common cable machine casting area is finished, the area cable machine is turned to 13-018 common cable machine casting area, is sequentially cast from downstream to upstream, and is circularly cast according to the sequence until the warehouse is received.

4) The regional casting simulation of the warehouse surface should follow the following assumption, including the total construction time of one casting warehouse, the concrete warehouse-in and transportation sequence between two warehouses and the concrete production quality;
the simulation of the bin face partition pouring should follow the following assumptions:
4.1 Taking the total time consumption from the first tank of concrete to the end of the vibration of all blank layer concrete as the total construction time length of one pouring bin.
4.2 When the two cabins are combined, the cable machine covering the two casting cabins simultaneously starts to put the concrete of the second cabin surface into the cabin for transportation after the first blank layer concrete of the first cabin surface is put into the cabin.
4.3 The strength of the concrete production system can be considered to fully meet the requirement, and the construction process is not influenced.
5) Setting boundary conditions of two-bin combined pouring system simulation, wherein the boundary conditions comprise limit of working range of the cable, limit of working interference of adjacent cable and concrete quality constraint;
5.1 The working range of a single cable machine is limited to the upper limit y (mi) and the lower limit y (ni) (i=1, 2, …, N) of the cable machine, and for the i-type cable machine, the casting condition of the casting bin surface a needs to meet the following conditions:
wherein:
y (mi) is the Y coordinate of the upper limit of the movement of the i-number cable machine;
y (ni) is the Y coordinate of the lower limit of the movement of the i-number cable machine;
y (a) is the Y coordinate of the center point of the casting bin surface a;
l (a) is the length of the casting bin surface a in the Y direction.
5.2 When a single cable machine cannot meet the requirement of a warehouse surface pouring task, a plurality of cable machines are required to be used for joint pouring. The adjacent two cable machines are allowed to have a certain overlapping construction range, but in order to consider the safe construction, the adjacent two cable machines must keep a sufficient safe distance, so when the joint casting is carried out, the casting conditions of the casting bin surface a and the casting bin surface c need to meet the following conditions:
wherein:
y (a) is the Y coordinate of the center point of the casting bin surface a;
y (c) is the Y coordinate of the center point of the casting bin surface c;
l (a) is the length of the casting bin surface a in the Y direction;
l (c) is the length of the casting bin surface c in the Y direction;
s is the minimum safety distance between adjacent cable machines.
5.3 When dam concrete is poured by adopting a tiling method, in a high-temperature season or in a high-temperature period, and when the area of a bin number is large, the concrete is put into the bin and then is leveled in time and vibrated, and the upper blank layer concrete is timely covered, so that the covering time is ensured to be 3-4 hours.
6) Constructing simulation models of the casting construction systems of adjacent strips of the same blank layer, adjacent blank layers of the same strip and the full blank layer in a partition mode under the condition of two-bin combined casting by using a model component of simulation software EZstrobe according to casting bin information, as shown in figures 3-10;
and when the two cabins are combined for casting, a single cable machine is responsible for casting a cabin surface fixing area, namely, the cable machine firstly carries out concrete transportation of one cabin surface blank layer and two strips, then carries out concrete transportation of two cabin surface blank layers and one strip and sequentially carries out blank layer coverage. And each link and time parameters thereof in the concrete pouring process are shown in the simulation model diagram, and simultaneously, the resource flow direction in the construction system is shown. The concrete pouring process of the adjacent strips of the same blank layer comprises concrete transportation links, inter-strip cable machine circulation and inter-strip flat bin vibration circulation.
7) Considering the three aspects of the comprehensive cable machine, the cabin surface construction machine and the cabin surface partition scheme, and combining a construction system simulation model to draw a partition construction scheme with balanced distribution and unbalanced distribution, wherein the scheme comprises a scheme similar to a control area of the cable machine and a scheme similar to a control area of the warehousing capacity of the cable machine, as shown in fig. 11-14; and when the two cabins are combined, whether the position of the cabin surface has a superposition area or not is also considered, so that different cable machine pouring schemes are adopted. The control area of each cable machine is kept as consistent as possible on the basis of considering the shape of the bin surface according to the scheme that the control areas of the cable machines are similar. When the casting scheme of the cabin surface cable machine is determined, not only the number of the cable machines but also the serial number of the cable machines adopted by casting of the two cabin surfaces are determined. When the two-cabin combined pouring relates to a public cable machine, the setting of the partition scheme needs to comprehensively consider the circulation time and the concrete pouring amount of the cable machine on the two cabin surfaces so as to shorten the total pouring time of the cabin surface partition. The control area scheme of the cable machine warehouse entry capability is known by the person skilled in the art, is a conventional technical means, and needs to consider whether the working cable machine can cover the areas of the two casting warehouses and the area of the cable machine warehouse entry capable of adjusting and controlling when determining whether the two casting warehouses can be cast in a combined mode.
8) And (3) performing simulation calculation by using simulation software EZstrobe, and calculating the pouring time of all blank layers in each partition with balanced distribution and unbalanced distribution and the concrete warehousing strength of the cable machine, thereby optimizing the partition construction scheme. Because the single cycle time of the cable machine running on the bin surface is different, simulation calculation is needed by adopting the time parameters corresponding to the cable machine, and the calculation result comprises the partition pouring time length and the bin-in strength of the cable machine.
According to the selected two-bin combined pouring bin surface related information, the bin surface zone pouring is shown in a table 6 as a two-bin combined pouring cable machine warehousing time parameter table, simulation parameters are substituted into a simulation model to calculate, a table 7 as a two-bin combined pouring cable machine control area similar scheme simulation calculation result table of each zone of the cable-containing machine hanging part, and a table 8 as a two-bin combined pouring cable machine warehousing capacity control area scheme cable-containing machine hanging part simulation calculation result table.
