Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete transportation, and more specifically, to a high-altitude, large temperature difference, and large height difference concrete transportation chute system. Background Art
[0002] When concrete is transported down a steep slope with a large height difference without a temporary road, it is generally transported by a chute. A continuous steel circular chute is set from the starting point to the end point of the transportation. After the concrete is unloaded into the chute by the tank truck, it slides down along the pipe body until the end point completes the transportation. When using a traditional chute to transport concrete, due to the different flow rates of aggregates and mortar, it is easy to cause pipe blockage due to aggregate accumulation. After the pipe is blocked, the chute needs to be dismantled and replaced section by section, affecting the construction progress and causing certain economic losses; the concrete after transportation is prone to segregation, which affects the working performance of the concrete. It is necessary to use additional devices such as mixing tanks to mix it for secondary mixing to eliminate segregation. In addition, for the concrete transportation project with a large height difference and no temporary road in the deep canyon on the plateau, it is also faced with high altitude low pressure, large temperature difference, strong wind environment, and harsh construction environment, which puts forward higher requirements for heat preservation, moisture retention, anti-segregation, and anti-blocking pipe during the transportation of concrete chute. In view of the above problems, it is urgent to develop a chute system suitable for the transportation of concrete with large temperature difference and height difference in deep canyons at high altitude, which has the functions of heat preservation, moisture retention, anti-segregation, and anti-blocking pipe.

[0013] 1. The utility model provides a high-altitude, large temperature difference, and large height difference concrete transportation chute system. The chute is formed by splicing open segments and standard segments. The concrete transportation status can be grasped in real time through the notches on the open segments. When pipe blockage occurs, concrete transportation is stopped in time, and the concrete at the blocked pipe is manually dredged through the notches, which can effectively ensure the transportation speed of concrete and is conducive to maintaining the working performance of concrete.
[0014] 2. The utility model provides a high-altitude, large temperature difference, and large height difference concrete transportation chute system, and an insulation layer is arranged at the bottom of the chute, which can cope with the large temperature difference environment in high-altitude areas and prevent the concrete temperature from being too low to affect its performance.

[0021] like Figure 1 and Figure 2 As shown, the utility model provides a high-altitude, large temperature difference and large height difference concrete transportation chute system, which is arranged on a steep slope mountain 6, and includes: a chute 3, a feed hopper 1 and a concrete pump 5; the feed end of the concrete pump 5 is provided with a pump hopper 4, the chute 3 is arranged obliquely downward along the slope of the steep slope mountain 6, the discharge end of the feed hopper 1 is connected with the feed end of the chute 3, and the discharge end of the chute 3 is connected with the feed end of the pump hopper 4; the bottom of the chute 3 is provided with an insulation layer 8; the chute 3 is formed by alternately splicing a plurality of open segments and a plurality of standard segments, and the open segments are provided with slots.
[0022] In this technical solution, the feed hopper 1 and the pump hopper 4 are respectively placed in the relatively flat areas at the upper and lower ends of the steep slope 6, and then the feed hopper 1 and the pump hopper 4 are connected through the chute 3. After the concrete enters through the feed hopper 1, it is transported to the pump hopper 4 through the chute 3 and enters the concrete pump 5. After being stirred by the concrete pump 5, the concrete is stirred to eliminate segregation and is pumped to the pouring site for pouring. The chute 3 is formed by splicing the open segment and the standard segment. The concrete conveying status can be grasped in real time through the notch on the open segment. When the pipe is blocked, the concrete conveying can be stopped in time, and the concrete at the blocked pipe can be manually cleared through the notch. The insulation layer 8 is provided at the bottom of the chute 3 to cope with the large temperature difference environment in high altitude areas and prevent the concrete temperature from being too low to affect its performance.
[0023] In another technical solution, one opening segment is provided on the slide pipe 3 every five standard segments. The standard segment and the opening segment can adopt the same structure. In this embodiment, the standard segment and the opening segment are processed into a standard pipe segment with an upper opening of 34 cm, a lower opening of 30 cm, and a pipe body of 2 m using 5 mm steel plates. The opening segment has a 30 cm long notch on the top surface in the middle. Buckles and latches can be used to connect two adjacent standard segments, and between the standard segment and the opening segment.
[0024] In another technical solution, a transparent cover plate 7 is provided on the slot, and the transparent cover plate 7 is hinged with the opening segment to open or close the slot; on the vertical section of the opening segment, the central angle α corresponding to the slot is not greater than 90°. The transparent cover plate 7 can be a transparent PVC cover plate, which can prevent debris from falling into the chute 3 and facilitate manual observation of the flow of concrete in the chute 3. When a pipe is blocked, the corresponding transparent cover plate 7 can be opened to clear the pipe, which is convenient and quick.
[0025] In another technical solution, a discharge trough 2 is provided between the discharge end of the feed hopper 1 and the feed end of the chute 3, and between the discharge end of the chute 3 and the feed end of the pump hopper 4. The discharge trough 2 is used to smoothly connect the feed hopper 1, the chute 3 and the pump hopper 4, so as to reduce the installation requirements of the feed hopper 1 and the pump hopper 4. The concrete is introduced from the feed hopper 1 into the chute 3, and from the chute 3 into the pump hopper 4 through the discharge trough 2.
[0026] In another technical solution, on the vertical section of the chute 3, the central angle β corresponding to the thermal insulation layer 8 is not less than 180°. The thermal insulation layer 8 covers the bottom of the chute 3 as much as possible to ensure the thermal insulation effect on the concrete in the chute 3. Specifically, the thermal insulation layer 8 is an electric blanket, which is wrapped around the bottom of the chute 3 and can provide stable thermal insulation performance.
[0027] In another technical solution, a circle of heightening plates is provided along the outer edge of the top of the pump hopper. The pump hopper 4 adopts a large-volume hopper. In actual use, the pump hopper 4 can be heightened by steel plates on the basis of the original hopper to accommodate more concrete. When the concrete is transported to the end of the chute, it is unloaded into the pump hopper 4. The concrete pump 4 is directly used to perform secondary mixing on the transported concrete and pump it for pouring, eliminating concrete segregation and saving secondary mixing devices, thus saving costs. In this embodiment, the top of the pump hopper 4 is heightened by 50 cm using steel plates.
[0028] In another technical solution, a plurality of clasps are arranged at intervals on the slide pipe 3, and the clasps are fixed to the steep slope mountain body 6 by steel wire ropes. The steel wire rope can be a longer steel wire rope, which is inserted and fixed to the steep slope mountain body 6, and then the clasp is clamped on the slide pipe 3 and connected to the steel wire rope securely.

It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented.
