Abstract
The utility model discloses a device for reducing aggregate segregation of high-head roller compacted concrete, which comprises a regulating hopper (1), a box-type full bobbin tank body (2) and a supporting structure, wherein the height difference from the top of the regulating hopper (1) to the bottom of a discharge port of the box-type full bobbin tank body (2) is greater than or equal to 90m. The device is characterized in that at least two hydraulic valves (3) for controlling the filling degree of the concrete in the box-type full bobbin tank body (2) are arranged at intervals in the box-type full bobbin tank body (2) from top to bottom. The hydraulic valves controlled by a computer are additionally arranged at fixed points on the basis of a box-type full bobbin used in the conventional engineering and the filling degree of the roller compacted concrete in the box-type full bobbin tank body can be regulated, so that the aggregate segregation phenomenon of the roller compacted concrete is reduced, the construction progress of the roller compacted concrete can be quickened and construction quality of the concrete is improved.
Description
Technical field
The utility model relates to a kind of device that reduces high drop roller compacted concrete Segregation, belongs to Hydraulic and Hydro-Power Engineering concrete construction technology field.
Background technology
The many areas especially a lot of Dam dam site in Southwest Mountainous Areas river valley are in the shape of the letter V more, two sides side slope is precipitous, during this class dam construction, orographic factor is larger on the concrete impact of putting in storage, although concrete warehousing can fill path link by downstream river course and crossed dump truck and put in storage early stage, but the layout of road may affect the construction period of downstream apron, bank protection, and arrange that traffic may have certain difficulty.For addressing this problem, in engineering in the past, adopted box full packages to carry out roller compacted concrete vertical transport, by the method for putting in storage of transporting in tipping truck storehouse, but in the design of box full packages, it regulates the discrepancy in elevation of hopper and storehouse face to cross conference the situation of roller compacted concrete Segregation is increased the weight of, according to the engineering experience of having implemented at present, the maximum discrepancy in elevation that box full packages puts in storage can reach 90m.Because roller compacted concrete is a kind of concrete of poor cementitious material, this has increased the weight of the phenomenon of the concrete aggregate separation that causes because the discrepancy in elevation is excessive, according to related specifications requirement, rolled concrete cylinder surface does not allow the phenomenon that occurs that large aggregate is concentrated, therefore, existing full packages vertical transport technique needs to improve.
Summary of the invention
The purpose of this utility model is as overcoming the Segregation phenomenon of roller compacted concrete aggregate in vertical transport process, a kind of device that reduces roller compacted concrete Segregation is provided, regulate the discrepancy in elevation and the fullness degree of aggregate in full packages that under aggregate, unload, thereby reduce roller compacted concrete aggregate, arrive the Segregation phenomenon after the face of storehouse.
To achieve these goals, the technical solution adopted in the utility model is a kind of device that reduces high drop roller compacted concrete Segregation, its structural feature is that it comprises adjusting hopper and box full packages groove body and braced structures, regulate hopper, box full packages groove body and feed opening to be linked in sequence from the top down, braced structures is used for supporting whole device, and braced structures adopts conventional prior art.That is to say that the utility model is used in regulates the top of hopper to the discrepancy in elevation of the discharging opening bottom of box full packages groove body, to be more than or equal to the situation of 90m, the utility model is avoided Segregation in order to overcome in so large discrepancy in elevation situation, and in box full packages groove body, from up to down interval arranges at least two for controlling the hydraulic valve of box full packages groove body inner concrete fullness degree.This hydraulic valve is controlled by computer.Because the utility model has installed this hydraulic valve of being controlled by computer additional, can in concrete warehousing process, regulate the fullness degree of concrete in box full packages groove body, thereby avoid concrete Segregation.
Certainly, the discrepancy in elevation between upper and lower two adjacent hydraulic valves is also a technical essential of the present utility model, and the utility model is design like this: the discrepancy in elevation in box full packages groove body between upper and lower two adjacent hydraulic valves is 30～40m.
In addition, this box full packages groove body of the present utility model is that the standard component feed pipe by fixed length is formed by connecting, and the versatility of this standard component is good, manufactures processing also convenient.Connected mode is mainly that flange connects.When the total length of full packages groove body is not the feed pipe integral multiple of fixed length, also can splice by the feed pipe of random length.
The utility model has the advantage of: in engineering in the past, on the basis of box full packages used, fixed point has installed the hydraulic valve of being controlled by computer additional, can regulate the fullness degree of roller compacted concrete in box full packages groove body, thereby reduce the Segregation phenomenon of roller compacted concrete, can accelerate grinding concrete construction progress, improve concrete construction quality.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Description of reference numerals: 1-regulates hopper, the box full packages groove of 2-body, 3-hydraulic valve.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the utility model is to adopt a kind of construction equipment dump truck transportation roller compacted concrete, then by dump truck discharging to regulating hopper 1, roller compacted concrete aggregate unloads for 2 times to construction storehouse face by box full packages groove body, wherein in box full packages groove body 2, fixed point has been installed the hydraulic valve 3 of being controlled by computer, its direct object is to have reduced the height that unloads under aggregate is disposable, roller compacted concrete aggregate is riddled in box full packages groove body 2, after the height simultaneously unloading under disposable due to aggregate reduces, can effectively weaken the Segregation phenomenon of unloading under roller compacted concrete to after the face of storehouse, for guaranteeing engineering grinding concrete construction quality and accelerating grinding concrete construction progress and established technical foundation.
Certainly, be more than concrete exemplary applications of the present utility model, the utility model also has other embodiment, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the desired protection domain of the utility model.
