Abstract

The invention discloses a standard assembly type ladder cage for vertical shaft up-down travelling and a construction method thereof. The standard assembly type ladder cage comprises at least two unitladder cages which are stacked from bottom to top and are detachably arranged, wherein each unit ladder cage comprises a rectangular bearing framework and a group of stairs which are fixedly arrangedin the rectangular bearing framework; each rectangular bearing framework is formed by lapping steel tubes, and comprises four vertical rods and at least two layers of rectangular frameworks which arearranged on the four vertical rods; each rectangular frame is formed by connecting four horizontal rods end to end and fixedly arranging the four horizontal rods on the four vertical rods; the stairsare fixedly arranged between upper and lower adjacent rectangular frameworks; a platform plate is arranged between the two transverse horizontal rods and at the two sides of each stair; and the platform plate comprises a framework formed by welding square steel and a wooden plate which spreads on the framework. The standard assembly type ladder cage has the characteristics of safety, applicability and the like, has a very good popularization and practical value, and generates good economic benefits after being widely promoted and applied.

Description

technical field [0001] The invention relates to the technical field of non-excavation construction, in particular to an assembled ladder cage for walking up and down a standardized shaft and a construction method thereof. Background technique [0002] In the process of non-excavation construction such as shield tunneling and underground excavation in deep foundation pits, it is necessary to build down stairs for use by managers and construction personnel. Traditional downhole stairs take up a lot of space, are inconvenient to install, and are not suitable for some shafts with small design sizes, which may easily cause safety problems. Therefore, it is necessary to design a standardized prefabricated ladder cage for walking up and down shafts to meet the needs of smaller sizes. Small shaft use requirements and safety requirements, to achieve the effect of safety, applicability and convenience. Contents of the invention [0003] The purpose of the present invention is to pr...
