Dwatering well device with integrated pile casing and well casing and construction method of dewatering well device
The invention discloses a dewatering well device with an integrated pile casing and well casing. The dewatering well device with the integrated pile casing and well casing comprises a pile casing, a well casing, a filter, a precipitation pipe and a well shoe type drill bit, the pile casing comprises a protection wall section pile casing and a filtering section pile casing, the well casing is arranged in the filtering section pile casing and is coaxially arranged with the filtering section pile casing, and the filter is arranged between the well casing and the inner filtering section pile casing. The invention further discloses a construction method of the dewatering well device, firstly, according to stratum distribution of exploration data, dewatering well device filter joints are sequentially assembled in advance, a sedimentation pipe is arranged in the well casing, after drilling of a drilling machine is completed, the prefabricated dewatering well device sinks into a hole section by section, the dewatering well device can directly work in cooperation with a water pumping pump, after being used, the device can be recycled. The dewatering well device can be applied to general engineering precipitation and recharge engineering, and is particularly suitable for conditions such as foundation pit or tunnel leakage disaster rescue precipitation and pressure reduction. Compared with a traditional well completion technology, the well completion process is optimized, and the time for filling a filter material on site in the well completion process after drilling is saved.
本发明公开了一种护筒与井管一体化的降水井装置，包括护筒、井管、过滤器、沉淀管、井靴式钻头，护筒包括护壁段护筒和过滤段护筒，井管设置在过滤段护筒的内部并与过滤段护筒同轴布置，过滤器设置在井管与内过滤段护筒之间。本发明还公开了降水井装置的施工方法，首先在按勘察资料的地层分布，事先依次装配好降水井装置过滤节，井管内安置好沉淀管，在钻机钻孔完成后，将预制的降水井装置分节下沉至孔内，配合抽水水泵可直接工作，使用完毕后也可回收再利用。本发明可应用于一般工程降水、回灌工程，尤其适用于基坑或隧道渗漏灾害抢险降水减压等情况应用。本发明相较与传统成井技术，优化了成井工序，节省了钻孔后成井过程中现场填滤料的时间。
