This invention discloses a clustered directional down-the-hole hammer drill bit for drilling large-diameter rescue wells. Further, it includes: a mounting body, multiple down-the-hole hammer units, multiple linear drive mechanisms, a monitoring mechanism, and a numerical control system. Each down-the-hole hammer unit is slidably mounted on the mounting body. The multiple down-the-hole hammer units are distributed circumferentially at intervals along the mounting body. Each linear drive mechanism is disposed on the mounting body. The output end of each linear drive mechanism drives and connects to its corresponding down-the-hole hammer unit. The monitoring mechanism is disposed on the mounting body, with its detection end facing the ground surface. The monitoring mechanism is used to detect the ground environment. The numerical control system is disposed on the mounting body, and its signals are connected to each linear drive mechanism and the monitoring mechanism. The numerical control system is used to control the operation of each linear drive mechanism based on the detection data from the monitoring mechanism, so as to adjust the working mode of each down-the-hole hammer unit according to the ground environment.

This invention relates to the field of municipal drainage technology, and more particularly to a pressure relief well and a water flow energy dissipation method. The pressure relief well includes an inlet pipe and an energy dissipation and anti-scour device; the outlet of the inlet pipe is located at the bottom of the well and faces upwards, and the anti-scour device is located at the outlet of the inlet pipe; the energy dissipation and anti-scour device includes an energy dissipation basin and an energy dissipation ring, the energy dissipation ring protruding upwards from the bottom of the well and surrounding the energy dissipation basin; the energy dissipation basin includes grid bars and at least two energy dissipation discs, the grid bars being arranged between the energy dissipation discs and between the energy dissipation discs and the bottom of the well, the diameter of the upper energy dissipation disc being larger than the diameter of the lower energy dissipation disc, and each energy dissipation disc having an energy dissipation hole. This invention solves the problem of water flow impact on drainage wells and extends the service life of drainage wells.
