| titleOfInvention | Building engineering foundation ditch precipitation is with from towards formula step -down well |
| abstract | The utility model discloses a building engineering foundation ditch precipitation is with from towards formula step -down well, including well casing and high -pressure water pipe, well casing lateral wall evenly distributed has the round hole, and the well casing wraps up 60 purpose nylon filter screens outward, and the well casing lateral wall is equipped with the opening, and the well casing lower extreme is equipped with toper portion, and toper troops under one's command end is equipped with the opening, high -pressure water inlet pipe advances water piping connection by plastics inlet tube and steel and constitutes, the opening that the subordinate end of toper was worn out downwards to well casing inside is followed to the steel inlet tube, and the steel inlet tube is worn out the toper troops under one's command and is held the partial upward welding of open -ended to have the blade. Compared with the prior art, the utility model the advantage be: being less than pressure -bearing water water level or producing the hole end when suddenly gushing when the ground elevation of digging a well before the construction, the filter material can be filled out after creeping into and reaching projected depth and clear hole to the wellhole, has saved and has pulled out drilling rod and mounting shaft plumber skill, has avoided collapsing the hole because of the wellhole and has led to the fact to install the well casing in the wellhole, simple structure, convenient to use, the practicality is very high, low cost, convenient operation, the security is good, and strong adaptability has better application prospect. |
