Problems solved by technology
[0004] The purpose of the present invention is to provide a unidirectional flow artificial excavation pile dewatering system in shale geology and its construction method, to solve the problem of artificial excavation pile construction in shale geological engineering, which is adjacent to the sea lake due to the construction environment. It is complex and difficult. During the construction of manual excavated pile foundations, one-way linear lake water seepage in shale geology is very likely to occur, resulting in the failure of construction of individual manual excavated piles in some single buildings. Technical problems such as tube well dewatering and other construction schemes cannot be effectively implemented

The invention relates to a precipitation system for a unidirectional flashy flow manual hole digging pile in shale geology and a construction method thereof for a project where a unidirectional flashyflow is formed in a hole as a result of underground water seepage when a basic manual hole digging pile is excavated. The system comprises a basic manual hole digging pile and an cut-off manual holedigging pile, wherein the cut-off manual hole digging pile is arranged close to the basic manual hole digging pile and is located on a flashy flow channel formed by unidirectional seepage. The construction method provided by the invention is originated from a U-shaped pipe principle in physics, and the cut-off manual hole digging pile forms three U-shaped pipes different in height with the basic manual hole digging pile and lake water simultaneously, wherein the supporting layer of the cut-off manual hole digging pile is about 500mm deeper than that of the basic manual hole digging pile; whenthe basic manual hole digging pile is constructed, seeped lake water is cut off through the cut-off manual hole digging pile, and water in the cut-off manual hole digging pile is discharged out of thehole through an immersible pump, so that the amount of seeped water in the basic manual hole digging pile to be constructed is kept minimal, and the safety of the construction environment is also guaranteed while guaranteeing the construction quality.
Description
technical field [0001] The present invention relates to the field of artificial excavation pile dewatering construction, in particular to a unidirectional gushing flow artificial excavation pile dewatering system in shale geology and its construction method, which is suitable for the situation where groundwater seepage occurs when manual excavation piles are excavated in shale layers. Engineering that causes unidirectional flow in a hole. Background technique [0002] With the development of construction engineering foundation and foundation construction technology, various types of foundation construction precipitation technologies are becoming more and more perfect, but they often cannot satisfy engineers' pursuit and exploration of new precipitation technologies. At present, the main methods to solve the problems of foundation and foundation engineering dewatering construction include light well point dewatering, jet well point dewatering, electroosmotic well point dewate...
