TECHNICAL FIELD
[0001] The utility model belongs to deep hole drainage technical field relates to the small aperture deep hole water pumping tool. BACKGROUND
[0002] In geological exploration, mining and foundation treatment and many other engineering fields, the problem of water accumulation in small-diameter deep holes often occurs during construction, which is universal in actual operation and has a potential negative impact on the smooth progress and final quality of the project. For example, in geological exploration, when drilling equipment drills a small-diameter deep hole in the rock layer, groundwater may flow into the hole, especially when it approaches the aquifer, the water accumulation phenomenon is more serious. If the water is not removed in time and effectively, it will be difficult to accurately obtain the geological information of the rock sample, and thus affect the judgment of the underground geological structure. In mining, deep hole blasting is a common technical means, but after the drilling of the blast hole is completed and before the explosive is put into the hole, the water in the hole will seriously affect the drilling and charging construction. For foundation treatment projects, when deep foundation reinforcement is carried out in soft soil foundation or filled soil foundation, water accumulation in small-diameter deep holes will hinder the correct injection and distribution of reinforcing materials, affect the bearing capacity and stability of the foundation, and thus affect the safety and service life of the building.
[0003] At present, for the pumping of water accumulation in small-diameter deep holes, traditional methods such as small submersible pumps and simple siphon devices are mainly used. However, these methods have many shortcomings. Due to the size limitation of the small submersible pump, it is difficult to adapt to small-diameter deep holes of different diameters, and there are also difficulties in installing the submersible pump and pump pipe, which may cause the pump body to be stuck, the submersible pump to be clogged by mud and stones, resulting in low pumping efficiency, and even the submersible pump to be frequently burned out. The simple siphon device requires that the elevation of its drainage outlet end must be lower than that of the water body to be pumped, and its application range is extremely limited, for example, for the water pumping conditions at the bottom of a foundation pit, the elevation of the drainage outlet end of the siphon device is usually higher than that of the water body to be pumped, and the siphon cannot be formed, so its application range is greatly limited. In addition, the existing pumping tools perform poorly in complex deep hole conditions. When the water in the hole contains impurities, mud or particulate matter, these tools are prone to clogging, such as the water inlet of the submersible pump being clogged by debris, and the accumulation of impurities in the siphon pipe causing poor water flow. Once clogging occurs, a lot of time and manpower is needed for cleaning and maintenance, and the progress of the entire project may be affected due to tool damage, increasing construction costs.
[0004] In summary, the development of a tool with simple structure, convenient operation, strong adaptability and high efficiency for pumping water in small-diameter deep holes has important practical significance for solving the problem of water accumulation in small-diameter deep holes which is common in the current engineering field, and can effectively improve the construction efficiency, ensure the engineering quality, and reduce the engineering risk and cost.
