The invention discloses a method for processing support steel column construction not in place in foundation pits. By arranging construction joints in a baseplate or platform, the rate of water leakage of the baseplate can be reduced. The method includes bonding water swelling strips on a column pile under a construction joint, pouring surrounding and below a concave face of the baseplate or platform, pre-embedding a steel plate of the concave face, and alternately arranging a connector and pre-reserved inserting bar, namely a horizontal steel bar, on the baseplate above the construction joint; vertically arranging a steel plate waterstop and the water swelling strips in pre-reserved positions, and chiseling; above the concave face of the construction joint of the baseplate or platform, covering a steel plate on a pre-embedded an elongated steep plate after the column pile is cut, welding the periphery of the steel plate and the elongated steep plate embedded on the concave face, and pouring the construction joint. By the aid of the method, the problems of the stability of a support system or baseplate water proofing due to the column pile construction not in place are solved; the method is simple and easy to construct and is economic.
Description
technical field [0001] The invention relates to a treatment method for a deep foundation pit support steel column, in particular to a treatment method for a deep foundation pit support steel column whose construction is not in place. Background technique [0002] With the acceleration of urbanization in our country, the development and utilization of underground space has developed rapidly, and the depth of foundation pits has become deeper and deeper, so the enclosure design and construction technology of deep foundation pits have also been continuously developed. The stability of the deep foundation pit project itself can only be guaranteed under the joint action of the three major systems of the enclosure structure, the horizontal support system and the vertical column. The use of steel columns in the design of foundation pit support has become common, but it is often encountered in engineering that the construction of steel columns is not in place due to various reasons....
