Technical Field
[0001] The utility model relates to a narrow valley dam concrete pouring system, which is applicable to the field of dam concrete pouring. Background Art
[0002] Pouring dam concrete is a key process in water conservancy project construction. There are various methods for pouring dam concrete. However, for dams built on narrow river valleys, the construction is more difficult and concrete pouring is more difficult. Since the distance from the two banks of the narrow river valley to the bottom of the valley is far, if the concrete transportation and pouring methods are not properly selected, concrete segregation and concrete cold joints will occur.

[0020] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0021] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.
[0022] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.
[0023] like Figure 1 As shown, this embodiment provides a narrow valley dam concrete pouring system, including a chute, a hanging tank and a tower crane.
[0024] In this embodiment, chutes are provided on the river valley slopes on both sides of the dam. The chutes extend from the top of the slope to the bottom of the slope. The chutes are fixed to the slope below via a support body. A feeder and a belt conveyor are provided on the top of the slope. The feeder is used to receive concrete poured by a concrete transport truck, and the belt conveyor is used to transport the concrete sent by the feeder to the chute.
[0025] In this example, the tower crane is set on the valley floor, and the tower crane hook can hook the hanging pot, so as to hoist the hanging pot. The hanging pot can be used to receive concrete delivered by the chute, and the tower crane can hook the hanging pot through the tower crane hook, so that the hanging pot can move between the lower end of the chute and the warehouse surface at the bottom of the valley.
[0026] In this embodiment, a set of anti-segregation devices is installed on the chute every 4 meters of chute pipe. The anti-segregation device includes two tapered openings. The lower end openings of the upper and lower adjacent tapered openings are respectively facing the two sides of the chute axis, and the directions of the lower end openings of the two tapered openings are 90 degrees to each other.
[0027] In this example, the conical mouth is made of welded steel plates to slow down the flow rate of concrete. The two conical mouths at 90 degrees to each other are 1.2 meters apart. Since the openings at the lower ends of the two conical mouths are 90 degrees to each other, the concrete will rotate to a certain extent within the space of 1.2 meters, intertwine with each other, and mix again to achieve the effect of preventing segregation.
[0028] In this embodiment, a regulating valve is arranged at the bottom of the chute, and a hydraulic (or electric) arc door is used to control the flow rate of concrete. Closing or slightly opening the arc door allows concrete to be stored in the chute (full or half pipe) and flow out slowly to prevent the concrete from flowing too fast and causing segregation.
[0029] In this embodiment, chutes are arranged on both sides of the dam, and the number of concrete transport vehicles is reasonably configured to achieve continuous supply of concrete to the left and right banks, ensure the continuity of construction, and effectively avoid the occurrence of concrete cold joints.
[0030] The method of use of this embodiment is as follows: use a concrete transport truck to transport concrete from a mixing station to a feeder platform, put the concrete into the feeder, the concrete flows from the feeder into a belt conveyor, flows into a chute through the belt conveyor, flows into a hanging tank through the chute, and then uses the tower crane hook on the tower crane to lift the hanging tank to the warehouse surface for pouring.
[0031] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
