[0002] Due to the narrow valley, a large number of hydropower stations use underground power plants. With the increase of installed capacity, the scale of underground caverns is getting larger and larger, with large cross-sections, high depths, large diameters and complex structures as prominent features. The transportation and pouring of large-volume concrete is one of the most important links.

[0003] The vertical pipeline chute method uses ordinary steel pipes arranged at the top of the shaft as a chute to transport concrete from the ground to the structural parts. Existing studies often attribute pipeline impact wear to partial pipe flow. Control measures to reduce pipeline impact wear mainly include staged transportation, small-diameter transportation, and the installation of descending devices.

BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The accompanying drawings illustrate exemplary embodiments of the present invention and, together with the description thereof, are used to explain the principles of the present invention. These drawings are included to provide a further understanding of the present invention, and the accompanying drawings are included in and constitute a part of this specification and do not constitute a limitation of the embodiments of the present invention.

[0058] Figure 1 The present invention is a flowchart of a method for confirming the installation of a deep shaft concrete chute. DETAILED DESCRIPTION

[0059] To make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention 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 relevant content and are not intended to limit the present invention.

[0060] It should also be noted that for the convenience of description, Figure 1 Only the parts relevant to the present invention are shown.

[0061] In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0062] Example 1

[0063] Concrete slurry is a typical multiphase fluid, primarily composed of slurry and aggregate. The slurry envelops the aggregate as it migrates within the pipe. Coarse aggregate includes pebbles and gravel. Therefore, factors such as slurry flow velocity, pipe wall wear, and slurry segregation are influenced by the aggregate diameter, water-cement ratio, and pipe diameter. Pipeline specifications primarily focus on diameter and wall thickness. A reasonable diameter ensures efficient delivery, prevents blockage, and minimizes wear. A reasonable wall thickness ensures safety during concrete delivery, preventing hazards such as pipe breakdown and bursts.

[0064] This embodiment provides a method for confirming the installation of a deep shaft concrete chute, which can calculate the diameter, thickness, and length of the chute. The confirmation method includes the following steps:

[0065] Determine the maximum aggregate size d of the concrete to be transported m At present, the aggregate size range of hydraulic concrete is 5-30mm. When using this method, it is necessary to know the specific composition of the concrete and the maximum aggregate size.

[0066] Determine the concrete flow velocity v and flow rate Q in the chute. According to demand, estimate the flow velocity and flow rate of concrete discharged from the chute in advance to ensure the optimal pouring speed and quality during concrete pouring.

[0067] Calculate the inner diameter of the concrete chute based on the above requirements:

[0068] Determine R>4d m , meaning the diameter of the concrete delivery pipe should be no less than four times the aggregate particle size. Too small a diameter can cause pipe blockage. Furthermore, deep shaft construction requires a huge amount of concrete. Reducing the pipe diameter increases the flow rate within the concrete pipe, speeding up the erosion between the aggregate and the pipe wall, and exacerbating pipe wear. Therefore, the pipe diameter should not be too small.

[0069] If not, it proves that the flow velocity and flow rate are selected correctly, and the flow velocity and flow rate need to be re-determined; the flow velocity should usually be controlled between the critical flow velocity and the limiting flow velocity to prevent pipe blockage and segregation.

[0070] If yes, calculate the wall thickness δ of the concrete chute: Among them, T is the slip time, δ c is the average wear of the inner wall of the concrete chute within the time T (obtained from previous engineering experience), P is the impact pressure in the chute, and [σ] is the allowable stress of the pipe;

[0071] The thickness of the pipe wall has an important impact on the safe transportation of concrete. If the pipe wall is too thin, it will cause safety accidents such as pipe burst and pipe breakage due to factors such as pipe wear. If the pipe wall is too thick, it will greatly increase the cost of deep shaft construction and is not conducive to it.

[0072] If the material of the chute is a seamless steel pipe, then [σ] = 80 ~ 100 MPa; if the material of the chute is a cast iron steel pipe, then [σ] = 20 ~ 40 MPa.

[0073] The concrete entering the chute is pumped by a concrete pump and has a certain initial velocity, so it is necessary to determine the initial concrete discharge velocity v0.

[0074] Assuming the chute is long enough, the concrete flows downward at a certain initial velocity. As the flow velocity increases under the action of gravity, the collision loss between the concrete and the pipe wall and particles will inevitably increase. The resistance eventually generated will be equal to the gravity, and the concrete will begin to move at a constant speed. This speed is called the terminal velocity. It is assumed that the terminal velocity is equal to the chute velocity.

[0075] Determine the minimum vertical drop distance of the chute according to the initial material discharge speed and the chute flow rate. Where c is the correction coefficient determined by empirical methods, and g is the acceleration due to gravity;

[0076] Since the filling slurry moving in the vertical pipe does not move downward in a uniformly accelerated straight line under the influence of various factors according to the free-fall motion theory, but is affected by the friction of the pipe wall and air resistance, the above formula needs to be corrected. The correction coefficient is c, and the value of c is 0.7~0.8.

[0077] Determine the vertical shaft depth H0;

[0078] Judge H m <H0. If yes, the vertical drop distance of the chute is obtained (less than H0, equal to the concrete pouring height), which proves that even if the descender is not installed, the concrete has reached the sliding speed before it is slid to the bottom of the chute. Therefore, the vertical drop distance of the chute can be flexibly adjusted according to the vertical depth of the well.

[0079] If not, install a descender on the chute and obtain the vertical drop distance of the chute after the installation of the descender (less than H0, equal to the concrete pouring height). This proves that if the descender is not installed, even if the concrete is slid to the bottom of the chute, it still exceeds the sliding speed. Therefore, it is necessary to install a descender, and after the installation of the descender, ensure that the concrete speed at the chute outlet reaches the sliding speed.

[0080] Example 2

[0081] This embodiment is a further explanation of the first embodiment, that is, an explanation of the installation of a descending device.

[0082] After installing the descending device, determine the correction coefficient c after installing the descending device. x and through For H m <H0 for verification, if not, continue to reduce c x If the value is yes, then the corresponding descender installation requirement is output, 1>c>c x .

[0083] That is, by iterating c x The value of c is selected by gradually reducing x The value of H is used to change the minimum vertical drop distance of the chute until m<H0.

[0084] And, c x There is a corresponding comparison table with the installation requirements of the descender, by determining c x The need for additional installation can be determined.

[0085] Example 3

[0086] This embodiment is an explanation of the method for calculating the impact pressure in the slide pipe in the first embodiment, and the method includes:

[0087] Calculation formula: P = ρπR 2 v1(v1-v), v1 is the velocity before impact.

[0088] Before calculation, it is necessary to determine whether a descending device is installed. There are three situations.

[0089] 1. The descender is not installed.

[0090] 2. A descender is installed.

[0091] 3. At least 2 descenders are installed.

[0092] If the descender is not installed, v1 = v;

[0093] If a descending device is installed,

[0094] When the number of descenders n=1, v2=v0, H y is the vertical drop distance between the descender and the feed port. The installation position of the descender can be adjusted throughout the entire chute stroke. In general, let v1 = v to obtain H. y .

[0095] When the number of descending devices n>1, v2=0, H y H is the vertical drop distance between two adjacent descenders, y The methods of obtaining include:

[0096] Determine the shear stress on the chute when the concrete is in the critical state of blocking the chute Where K is the shear coefficient (usually 0.1), τ0 is the yield stress of the concrete in the critical state in the chute (usually 50 Pa);

[0097] Determine the critical flow rate Where ρ is the density of concrete, which is determined according to the parameters of concrete, and μ is the friction coefficient between concrete and pipe wall in the sliding state (generally 20 Pa·s).

[0098] Determine the minimum vertical drop distance between two descenders

[0099] Determine the maximum vertical drop distance between two descenders / the maximum vertical drop distance between the uppermost descender and the discharge port where v p The maximum velocity of concrete in the chute at the critical state of segregation (the maximum value is 16.1m / s, if the concrete velocity exceeds this value, segregation may occur);

[0100] Determine H y The value range of H y min <H y <H y max , that is, the installation of the descender between the slide pipes should be between the two values.
