Geological drill hole confined water spewing water head balanced construction method

Abstract

The invention discloses a geological drill hole confined water spewing water head balanced construction method. The method comprises the following steps that S1, a construction site is prepared, specifically, before large-diameter steel tube construction, silt nearby geological drill holes is removed, the geological drill holes are not blocked, and a pile driver parking site is selected on a roadside outside a foundation pit; S2, a steel tube pile driver is transported into the site, specifically, the pile driver is selected according to the weight and length of steel tubes and then enters the set position; S3, survey setting-out is conducted, specifically, survey setting-out is conducted in steel tube driving positions, and the positions are marked; S4, the steel tubes are hoisted in place, specifically, the steel tube pile driver is used for hoisting the steel tubes to the positions over the marked positions, and correction is conducted manually and cooperatively; and S5, the steel tubes are driven in place, specifically, the steel tube pile driver is used for driving the steel tubes to the set positions, and the geological drill holes are located in the steel tubes. By adoption of the geological drill hole confined water spewing water head balanced construction method, the problem that confined water in the geological drill holes in the bottom of the foundation pit spews can be effectively solved; and the method is easy and convenient to operate, good in implement effect, and capable of effectively preventing influence of underground water on foundation pit construction.

Description

technical field [0001] The invention relates to a geological drilling, in particular to a construction method for balancing a geological drilling pressurized water gushing water head. Background technique [0002] With the continuous acceleration of urbanization and industrialization in our country, various high-rise and super high-rise buildings have been sprung up, and various large-scale underground spaces have also been more and more developed and utilized. In the process of underground engineering construction, it is inevitable to be disturbed by groundwater. If the groundwater problem is not handled properly, it will bring major risks to the excavation of the foundation pit and the surrounding building environment. [0003] In the prior art, the treatment methods for geological borehole pressurized water gushing are mainly divided into three categories: [0004] (1) Grouting plugging, through the combination of grouting and soil to form a combination of high strength...
