Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Refer to attached figure 1 As shown in , a method for estimating the concrete engineering quantity of a hydroelectric power station's shore-type factory building according to the present invention divides the hydropower station's shore-type factory building into two parts: the lower part 1 of the factory building and the upper part 2 of the factory building, using the generator floor elevation reference plane 3 as a boundary area, then using the formula V x =c x h x B x L x Calculate and obtain the concrete engineering quantity V of the lower part 1 of the plant building x ; using V s =c s h s B s L s Calculate and obtain the concrete engineering quantity V of the upper part 2 of the plant building s ; while the estimation result V 总 =V x +V s ;in:

[0021] h x is the height of the lower part 1 of the plant; B x is the w...

Abstract

The invention discloses a method for estimating the concrete work amount of a shore-side workshop of a hydropower station, and belongs to the technical field of water conservancy and hydropower engineering. A method which is simple and quick, avoids the estimation of the size of a detail structure, and is suitable for estimating the concrete work amount of the shore-side workshop of the hydropowerstation is provided. The method comprises the steps that the shore-side workshop of the hydropower station is divided into a workshop lower portion area and a workshop upper portion area with a generator layer elevation datum plane as a boundary, and then the concrete work amount Vx of the workshop lower portion is calculated and obtained through the formula Vx = cxHxBxLx; Vs = csHsBsLs is adopted to calculate and obtain the concrete engineering quantity Vs of the upper part of the factory building; and the estimation result V < total > of the concrete engineering quantity of the shore-side workshop of the hydropower station is equal to Vx + Vs. According to the method, the corresponding concrete engineering quantity is estimated through a coefficient method, detail structure size estimation does not need to be conducted firstly, and the requirement for structural arrangement experience of calculation personnel is not high; accidental errors are effectively avoided by simply and quickly calculating the path; and the calculation workload is low, and the early-stage design period can be effectively shortened.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering, in particular to a method for estimating the concrete engineering quantity of a bank-type powerhouse of a hydropower station. Background technique [0002] The concrete engineering volume of the shore-type powerhouse of the hydropower station is usually added by stacking wood. First, the draft tube, volute, machine pier windshield, upstream and downstream underwater walls, floor system, frame, crane beam, and roof are completed based on experience. System, auxiliary power plant for tail water, tail water sluice piers, tail water platform and other structural layouts, and then calculate the concrete volume of each block of each structure in a list, and the concrete volume of each block is superimposed and summarized to obtain the concrete engineering quantity of each structure, and the concrete volume of each structure The engineering quantity is added to obtai...
