Description

Digital management system for construction progress of concrete dam based on vector graphics Technical Field The invention relates to the technical field of construction organization design tools and progress management in the process of building a hydraulic engineering dam, in particular to a vector graph-based concrete dam construction progress digital management system which is used for carrying out digital virtual binning on vector graphs of all parts of a concrete dam, assisting technicians in making construction plans, simulating the pouring process of engineering and carrying out data statistics and progress analysis on planned execution conditions. Background The concrete dam has the characteristics of huge size, special structure, complex construction process, large scale, long period, high risk, long-term influence on aging and the like. The construction period of the concrete dam of the large-scale reservoir is generally as long as a few years, and the challenges of large time span, complex external environment and multiple planning changes need to be dealt with. Therefore, the construction progress management of the concrete dam is a complex system work integrating engineering technology and resource scheduling, and is influenced by climate (such as rainy season and freezing period), geological condition change (such as new fault found in excavation), material supply (such as purchase price fluctuation of cement and steel bars and supply period of embedded parts), and the like, the construction plan needs to actively adapt to natural rules, and dynamic adjustment and optimization are timely carried out, so that construction period delay is avoided. The main content of concrete dam construction is to perform mass concrete pouring, in order to prevent excessive temperature cracks of the dam body in the construction process and adapt to the flow of pipelining operation, high-risk operation in pouring work is reduced, and technicians need to divide the dam body concrete into a plurality of independent sub-bins for sectional pouring, so that the contradiction between quality, safety and efficiency in mass concrete construction is solved. In the construction period, the concrete dam (even the arch dam with later grouting) is generally constructed and poured by each independent dam section in parallel, permanent or temporary transverse seams exist among the dam sections, and pouring of overflow surfaces, guide walls, flood gates and other parts is carried out at the later stage. The division work mainly divides the dam section or the part into a plurality of blocks from bottom to top by using horizontal construction joints with different heights, each block is a separately poured division, the thickness of the division is different according to the requirement of temperature control, the division is carried out in the strong constraint range of the bedrock at the bottom of the dam (the height range is 0.2L above the bedrock, L is the length of the length edge of the poured block), the general thickness is about 1.5-2.0 m, and the division outside the strong constraint range can be 3.0m. If the length in the upstream-downstream direction exceeds a certain limit (typically 60 m), it is also necessary to divide the block again in a direction perpendicular to the river with a longitudinal seam. It is counted that the number of sub-tanks of the large and medium concrete dams is generally more than 200. After the bin division schemes of all the parts are determined, a construction unit makes a casting plan according to the following steps of (1) calculating the volumes of all bins of a dam body and forming a sequence according to a reasonable construction sequence, (2) dividing the volumes of all bins by concrete casting strength of corresponding elevations respectively and calculating casting time of all bins, and (3) calculating the plan starting time and the plan finishing time of casting of all bins in the sequence in sequence by taking the set construction starting time as a starting point in sequence until the casting plan of all bins is finished. In the calculation process, more environmental influence factors such as annual flood requirements, downtime in severe weather conditions, rest time of legal holidays, supply plans of materials and materials, concrete production and transportation capacity, constraint conditions matched with professional equipment pre-buried conditions, quality inspection, defect treatment and the like are also required to be considered in dam body warehouse separation and pouring plans. In general, the casting plan is a linear work plan with a higher degree of time coupling, and adjusting the volume of a certain sub-bin or adding a constraint condition requires adjusting the time schedule of all subsequent sub-bins. At present, technicians can only conduct warehouse planning and casting plan making on drawings or in drawing software, a great deal of time is required to condu
