Open caisson construction device capable of rapidly discharging sewage
The invention relates to the field of sand foundation precipitation engineering, and particularly discloses a rapid pollution discharge open caisson construction device which comprises an open caisson pipe sleeve, a steel pipe is installed in the open caisson pipe sleeve, a gas injection pipe is arranged on the inner side of the steel pipe, the lower end of the gas injection pipe is connected with an exhaust pipe, and gas distribution exhaust pipes are installed on the outer side wall of the exhaust pipe in an array mode. A sand discharging pipe is installed on one side of the steel pipe, a water discharging pipe opening is formed in the position, located in the open caisson pipe sleeve, of one side of the steel pipe, and an upper sealing cover is installed at the position, located at the upper end of the steel pipe, of the outer side of the gas injection pipe. After gas injected by the gas injection pipe enters the interior of the exhaust pipe, the gas can more widely enter the interior of the steel pipe under the action of the gas distribution exhaust pipes arranged on the outer side of the exhaust pipe in an array mode, and the sand-water mixture is disturbed under the action of the air, so that sand-water in the steel pipe is in a boiling state; and sand is discharged from the sand discharging pipe outside the steel pipe.
本发明涉及砂基础降水工程领域，具体公开了一种快速排污的沉井施工装置，包括沉井管套，沉井管套的内部安装有钢管，钢管的内侧设置有注气管，注气管的下端连接有排气管，排气管的外侧壁阵列安装有分气排管，分气排管的内部安装有瓣膜，钢管的一侧安装有排砂管，钢管的一侧位于沉井管套的内部设置有排水管口，注气管的外侧位于钢管的上端安装有上封盖。注气管注入的气体进入到排气管的内部后，在排气管外侧阵列设置的分气排管的作用下保证了气体可以更加广泛的入到钢管的内部，空气的作用将砂水混合物进行扰动，使得在钢管内部的砂水处于“沸腾”状，使得砂从钢管外侧的排砂管排出。
