Deep foundation pit elevator shaft and sump nest support forming construction process

This invention relates to the field of deep foundation pit support construction technology, specifically a nested support construction process for deep foundation pit elevator shafts and sump pits. It solves the problem that traditional caisson waterproofing technology is prone to failure due to pit wall collapse in highly permeable gravel strata, making it difficult to create stable construction conditions. The process includes a steel caisson support structure, within which a steel caisson waterproofing structure is nested. This steel caisson waterproofing structure is used in conjunction with the steel caisson support structure for nested construction. This invention, through the nested cooperation of the steel caisson support structure and the steel caisson waterproofing structure, and the injection of a self-compacting concrete filling layer, achieves an integrated support and waterproofing effect during construction. It creates a stable, dry, and enclosed working space in easily collapsible, highly permeable strata, solving the problem of failure of traditional single waterproofing technology and creating safe and reliable conditions for subsequent structural construction.

An assembled steel corrugated plate retaining wall

This invention belongs to the field of road construction technology and discloses a prefabricated corrugated steel retaining wall. It includes anchor rods inserted into the corrugated sheet and soil layer to fix the corrugated sheet in place. A push rod passes through the anchor rod, which has a storage groove for storing concrete. A discharge port is located on the outside of the anchor rod; movement of the push rod causes the concrete in the storage groove to be discharged from the discharge port. A support part is slidably hinged to the push rod, allowing the push rod to move and expand the support part. The discharge port is located on the side of the support part near the corrugated sheet, allowing the discharged concrete to abut against the support part. The support part includes a slider and an anchor plate. The slider slides within a groove and can rotate freely. One end of the anchor plate is hinged to the slider. A support rod is connected to the side of the push rod near the groove, and one end of the support rod slides with the end of the anchor plate near the groove. This invention solves the problem in existing technologies where soft soil causes the corrugated sheet to easily loosen after installation, resulting in poor adhesion to the soil layer and subsequent collapse.
