Abstract

Provided is a sinking device for a water well pipe. The sinking device comprises a ratchet positioning device, a wheel shaft power mechanism, a guide pulley block, an operation platform and a steel wire rope. The operation platform is arranged right above a well hole and has an opening matching the well hole. A support is arranged on one side surface at one end of the operation platform. The wheel shaft power mechanism is arranged on the support. The ratchet positioning device is arranged on the wheel shaft power mechanism and positioned by means of the support. The sinking device for the water well pipe has following beneficial effects: due to the fact that the wheel shaft device is low in weight and gravitational effect and a lever principle are completely utilized, energy is saved and convenience and safety of construction are enhanced; due to application of the ratchet positioning device, the well pipe can be conveniently and stably positioned at any position so that safety, reliability and convenience are achieved; the wheel shaft power mechanism can easily draw the steel wire rope without mechanical coordinating operation such that construction flexibility is improved and construction cost is decreased; and the wheel shaft power mechanism is conveniently operated and helps to save manual power and decrease cost.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a method and device for sinking a well pipe. Background technique [0002] During the construction of downfall tube wells, one of the key procedures after mechanical hole forming is to place the sand-free concrete well tubes. The length of the well pipe is generally 900mm, and the diameter is 400mm. Before sinking, it is necessary to wrap the filter screen outside the well pipe and protect it with bamboo chips to improve the bending resistance of the wellbore to avoid "disconnection" of the upper and lower well pipes. During the construction of the tube well, it usually starts from the "well bottom" of the tube well, and the well tubes are connected while sinking to gradually form a "well bore". The gravel filter material is filled around the "well bore", and the tube well is formed after filling with clay near the well head to seal the well. [0003] The existing constructi...
