Description

Technical Field

[0001] The utility model relates to cast-in-place pile construction equipment, in particular to a pouring tool for cast-in-place piles. Background Art

[0002] In the construction of new energy photovoltaic projects, micro-cast-in-place concrete piles serve as an effective foundation treatment solution, providing excellent support and stability in complex terrains such as Gobi, mountains, and deserts. Through proper design and construction, micro-cast-in-place piles can meet the high foundation requirements of photovoltaic projects while reducing environmental impact.

[0003] Concrete micro-bored pile construction is characterized by a small volume (approximately 0.05 m³ per pile) and a large number of piles (approximately 21,204 piles for a 19MW power plant). Conventional concrete pump trucks or tanker chutes are not ideal for micro-bored pile construction. This is because the high output of concrete pump trucks or tankers can easily lead to excessive concrete being poured at once, overflowing the pile holes and causing significant concrete waste. Furthermore, concrete pump trucks or tankers are large and lack maneuverability, making them difficult to construct on closely spaced micro-bored piles. They also struggle to reach steeper terrain. Utility Model Content

[0004] In order to solve the above deficiencies in the prior art, the present invention aims to provide a pouring tool for bored piles, so as to achieve the purpose of reducing waste and improving construction efficiency.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a pouring tool for cast-in-place piles, comprising a mobile body and a hopper detachably provided on the mobile body;

[0006] The mobile vehicle is an electric tricycle or an electric four-wheel vehicle;

[0007] A discharge pipe for discharging concrete from the hopper is provided at the bottom of the hopper, a vibration motor is installed on the side of the hopper, and a discharge valve is provided on the discharge pipe.

[0008] As a limitation of the present invention, the discharge valve includes a barrier plate inserted into the discharge pipe and a handle fixedly connected to the barrier plate;

[0009] The barrier sheet is hinged on the outer side wall of the discharge pipe.

[0010] As a further limitation of the present invention, the hopper is connected to the mobile vehicle body by a pin shaft.

[0011] As a further limitation of the present invention, the top of the hopper is provided with a lifting lug for lifting.

[0012] As another limitation of the present invention, the rear end of the mobile body is provided with at least one telescopic leg.

[0013] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0014] (1) The utility model uses an electric tricycle or electric four-wheel vehicle as a mobile vehicle for transportation, which has strong traffic capacity and good maneuverability. It can quickly move to each micro bored pile hole for pouring construction, which can ensure high construction efficiency. In addition, the utility model adds a discharge pipe adapted to the micro bored pile hole on the hopper and is equipped with a discharge valve, so that the staff can control the single pouring volume of concrete to be almost equal to the capacity of the micro bored pile hole, thereby effectively avoiding the waste of concrete.

[0015] (2) The hopper of the present invention is connected to the mobile vehicle body by a pin shaft, which is convenient for disassembly or assembly. In addition, the hopper is provided with a lifting lug. When the construction terrain is steep and difficult for vehicles to reach, the hopper can be disassembled and poured using the lifting lug and a crane. The present invention has higher flexibility and can adapt to a variety of different terrains.

[0016] (3) The hopper of the utility model is also provided with a vibration motor, which can prevent the concrete from agglomerating in the hopper, ensure the fluidity and uniformity of the concrete, and provide vibration to improve the density and strength of the concrete; on the other hand, it can accelerate the flow of concrete, speed up the feeding speed, reduce the waiting time for pouring, and thus improve the construction efficiency.

[0017] In summary, the utility model has a simple structure and is easy to use, can improve construction efficiency and reduce concrete waste, and is suitable for use in the construction of concrete micro-cast-in-place piles in photovoltaic projects. BRIEF DESCRIPTION OF THE DRAWINGS
