Description
Technical field
The present invention relates to the analytical approach of cable machine work efficiency in the concrete construction of water conservancy and hydropower industry.
Background technology
In Hydraulic and Hydro-Power Engineering, checkdam concrete construction is the key that affects construction quality, progress and cost.Checkdam concrete construction comprises the series of processes such as concrete mixing, horizontal transport, vertical transport, storehouse face are closed a position, concrete vibrating, temperature control, relates to a series of working sources such as device of concrete mixing system, concrete horizontal haulage vehicle, vertical transport equipment, the machine of closing a position, concrete vibrating chassis, the artificial vibrating spear of concrete.Whether whether the quantity of all kinds of working sources and the model collocation between sufficient, equipment reasonable, is directly connected to operating efficiency, progress and the construction cost of engineering, even affects concrete construction quality.
In Practical Project, the configuration of working sources mainly relies on technician's engineering experience, according to the empirical parameter of all kinds of working sources operational efficiency, estimates required number of devices.But because the actual operating efficiency of working sources is subject to the impact (as operating personnel's skill level, the position of storehouse face, the distance of concrete transportation, storehouse surface current water job design etc.) of factors, the resource allocation proposal obtaining according to estimation often easily causes the unmatched phenomenon of working sources, causes the problems such as part resources idle, operating efficiency be low.Simultaneously owing to lacking the actual operating data of working sources, the general service condition that adopts the index coarse analysis working sources such as placing intensity (side's of building amount/build the time), be difficult to analyze the main cause of restriction operating efficiency, be difficult to improve resource allocation proposal and improve operating efficiency.
In prior art, resource distribution and the matching analysis be the construction experience based on engineering technical personnel mostly, and the construction experience parameter according to all kinds of working sources in similar engineering designs resource allocation proposal.There is following problem in prior art:
(1) generally take and build storehouse as analytic target, with the average placing intensity in single storehouse (the face side of building, storehouse amount/build the time), analyze the operating efficiency of each working sources in a whole set of construction.Average placing intensity is the result of each working sources combined action in a whole set of construction, is difficult to analyze the keystone resources of the total operating efficiency of restriction.
(2) owing to lacking the detailed construction data of working sources, the efficiency, utilization factor, vacancy rate etc. that are difficult to analyze respectively each working sources are index in detail, lack quantitative analytical approach, be difficult to the situation of utilizing of accurate analysis working sources, find the problem in working sources use procedure.
(3) when existing resource allocation plan designs, generally with reference to industry universal experimental formula estimations such as Construction for Hydroelectric Project handbooks.The mean parameter that numerous empirical parameters in estimation equation are numerous similar engineerings, parameter is chosen with technician's experience and is closely related, and is difficult to accurately reflect the practice of construction level of current engineering, affects the rationality of resource allocation proposal.
(4) cable machine is the key equipment of mass concrete construction, and the efficiency of cable machine is generated electricity most important to Hydropower Project on time or in advance.The operational efficiency of cable machine is comprised of numerous links, owing to lacking, cable machine is moved to the system of each link data, complete monitoring in the past, cannot targetedly each Link Efficiency be monitored, be analyzed and improve.
Rule of thumb parameter configuration working sources, easily causes resource distribution unreasonable.The operational efficiency of working sources is relevant to the self-characteristic of engineering (as the position of equipment operator's skill level, concrete transportation range, means of transportation, storehouse face and line production design etc.).In the past owing to lacking detailed practice of construction data, be difficult to the feature correction empirical parameter according to concrete engineering, the resource allocation proposal that can only estimate at the empirical value of similar engineering according to working sources, often easily cause inadequate resource, resources idle or resource matched irrational phenomenon, affect construction speed.
