Example Embodiment

[0026] Embodiment one

[0027] like figure 1 , figure 2 The structure of the ladder-climbing device used for manual digging piles shown in the present application is composed of an upper frame, a lower frame, a support rod and a cable buckle, and the upper frame is welded by Φ14 HRB400 steel bar connecting rods, And there are two cable buckles welded in the middle position, the skeleton diameter is determined according to the hole diameters of the different depth positions of the manual digging piles, and the diameter of each level of support device is 5-10cm smaller than the hole diameter of the position; the lower skeleton and the upper The frame structure and materials are the same; the support rods are welded to the upper and lower frames with Φ14 HRB400 steel bars, and the length of the support rods is 20cm; Bind the soft climbing ladder to the support device through the cable buckle.

[0028] The specific use process is as follows:

[0029] 1. Install the wellhead s...

Abstract

The invention discloses a crawling ladder device used for a manual hole digging pile and a method for going up and down a wellhole of the crawling ladder device, and belongs to the technical field ofcapital construction auxiliary equipment design and manufacturing. The crawling ladder device used for the manual hole digging pile and the method for going up and down the wellhole of the crawling ladder device are safe in use and large in working space, can be used circularly, and is low in cost. The crawling ladder device includes a soft crawling ladder, a limiting supporting system and a crawling ladder supporting frame. The crawling ladder device is limited by the limiting supporting system at the arrangement position in the radial direction in a pile hole through the crawling ladder supporting frame and the soft crawling ladder detachably hanged in the pile hole. The method for going up and down the wellhole is based on the crawling ladder device. Firstly the soft crawling ladder isput into the pile hole to be well supported; then a worker goes down into the pile hole; after the worker finishes, the soft crawling ladder and the limit supporting system are taken away to clear a space; and when the worker needs to go up, the soft crawling ladder and the limit supporting system are put down. The method for going up and down the wellhole not only overcomes the problem that people is prone to step empty on the soft crawling ladder, but also overcomes the problem that a rigid crawling ladder occupies the space so that unearthing is affected.

Description

technical field [0001] The invention relates to a ladder climbing device, in particular to a ladder climbing device for manual hole-digging piles, and belongs to the technical field of design and manufacture of infrastructure construction auxiliary equipment. The invention also relates to a method for going up and down a shaft using the ladder climbing device. Background technique [0002] In engineering construction, especially in suburban or mountainous areas, some deep foundation conditions such as backfill, miscellaneous fill or floating soil are often encountered. However, the built structures require a large load above the foundation and are subject to large mechanical equipment Due to the limitation of construction, it is necessary to use manual excavation pile foundation at this time. [0003] According to the "Technical Specifications for Building Pile Foundations" (JGJ94-2008) and the safety operation regulations for manual excavated piles, during the excavation p...
