The concrete warehousing and pouring system suitable for the long-distance small-hole-diameter box culvert provided by the utility model has the advantages of saving the use cost of engineering equipment, reducing the engineering energy consumption and avoiding the risk of long-distance pumping pipe blockage.
Description
Technical Field
The utility model relates to a concrete pouring system, in particular to a concrete warehouse entry pouring system suitable for long-distance small-hole-diameter box culverts.
Background
The drainage building of a large hydropower station is subjected to erosion of water flow with high sand content for a long time, the overflow surface of the drainage building is seriously damaged, and the drainage building needs to be subjected to bottom plate repair. When the hydraulic drainage building is repaired, the long-distance box culvert and the small hole diameter of the hydraulic drainage building are found, the concrete is difficult to put into a warehouse from the outlet and the inlet of the drainage building, and the quality of the concrete which is stirred on site is difficult to be ensured.
Disclosure of Invention
The technical problem to be solved by the utility model is to provide a concrete warehousing and pouring system suitable for long-distance small-hole-diameter box culverts, so that the difficult problem of concrete warehousing is successfully solved, and the risk of relay pipe blockage of a traditional pump truck is effectively avoided. Meanwhile, the number of ground pumps can be reduced, project funds are saved, the energy consumption of construction sites is reduced, good economic benefit and social benefit are obtained, and a beneficial reference is provided for concrete pouring construction of similar engineering structures in the future.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the concrete warehouse-in pouring system suitable for the long-distance small-hole-diameter box culvert comprises a connecting pipe, wherein the connecting pipe penetrates through the top of the box culvert, a feeding hole at the upper end of the connecting pipe is positioned outside the box culvert and connected with an aggregate funnel, and a discharging hole at the lower end of the connecting pipe is positioned in the box culvert and is used for receiving materials through a second concrete tank truck; and a ground pump is arranged in the box culvert, and the ground pump receives the concrete of the second concrete tank car and pours the concrete through a pump pipe.
The lower end of the ground pump is provided with a roller.
The second concrete tank car is a three-wheeled concrete tank car.
The utility model discloses a concrete warehousing and pouring system suitable for a long-distance small-hole-diameter box culvert, which adopts a concrete warehousing and pouring mode of 'tank truck relay dumping and in-hole ground pump warehousing and pumping'. The key point is that the blanking point of the concrete is arranged at the top of the drainage building, compared with the situation that a complex conveying device is not required to be set up for the storage from an inlet and an outlet, the storage difficulty of the concrete is solved. The maximum conveying distance of the ground pump is often far smaller than the length of a drainage building, and the risk of pipe blockage caused by pumping is avoided by adopting a special three-wheeled concrete tank truck to pour in a way of pouring materials back and forth in a hole in a separated manner.
Drawings
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
fig. 1 is a schematic structural view of the present utility model.
In the figure: the concrete truck comprises a first concrete tank truck 1, an aggregate funnel 2, a box culvert top covering layer 3, a box culvert top cover plate 4, a connecting pipe 5, a second concrete tank truck 6, a ground pump 7 and a pump pipe 8.
Detailed Description
As shown in fig. 1, a concrete warehouse entry pouring system suitable for a long-distance small-hole-diameter box culvert comprises a first concrete tank truck 1, an aggregate funnel 2, a connecting pipe 5, a second concrete tank truck 6, a ground pump 7 and a pump pipe 8. The connecting pipe 5 is buried at the top of the box culvert, concrete is vertically transferred from the ground to the inside of the box culvert through welding the aggregate funnel 2 on the connecting pipe 5, meanwhile, a special three-wheeled concrete tank truck (a second concrete tank truck 6) is arranged in the inside of the box culvert to be connected, and concrete is transported to a pouring position and is poured by using the ground pump 7.
Here, a group of connection pipes 5 are arranged, and concrete in other places is poured and transferred after being received by using a three-wheeled concrete tank car. The ground pump 7 and the pump pipe 8 are transported to the next bin section after one bin is used up, the ground pump 7 is provided with rollers and can be transported by using a winch, and the pump pipe is erected after manual transportation.
In the design process, technicians familiar with terrains and knowing the size of a narrow space, take the maximum safe distance of a ground pump without pipe blockage as the length of a casting bin section, and divide bins from an inlet to an outlet of a box culvert. Accounting the mounting position of the blanking pipe 5, excavating the soil covering layer 3 at the top of the box culvert to the cover plate 4 at the top of the box culvert, drilling holes on the cover plate 4 at the top of the box culvert to penetrate and fix the connecting pipe 5 in an inserted manner, and backfilling after the iron aggregate funnel 2 is welded. The engineering characteristics and the on-site actual conditions are combined to customize a small three-wheeled concrete tank car, the three-wheeled concrete tank car and the ground pump 7 are suspended in a box culvert, the three-wheeled concrete tank car is positioned right below a discharging point, the headstock faces to an outlet of the box culvert, the ground pump 7 is positioned at the tail end of a first casting bin, and a pump pipe is erected.
Pouring the concrete in the first concrete tank truck 1 to an aggregate funnel 2, conveying the aggregate funnel to a stirring cylinder of a three-wheeled concrete tank truck in a box culvert, and stopping discharging after the lower stirring cylinder is full. And the tricycle driver drives the tricycle concrete tank car to the position of the ground pump 7 in a reversing way, transfers the concrete to the ground pump 7 for pouring, and opens a discharging point after the concrete in the mixing drum is poured, so that the tricycle tank car is reciprocated until one-cabin pouring is completed.
