Introduction

This document belongs to the Class C standard specified in GB/T 15706 "General principles for safety design of machinery - Risk assessment and risk reduction": Drilling and foundation construction equipment belongs to construction machinery and equipment, and is equipment used for drilling holes in the ground or foundation construction in construction projects: GB/T 43746 "Safety requirements for drilling and foundation construction equipment" aims to specify the safety requirements for drilling and foundation construction equipment: Due to the complexity and diversity of the strata, the holes and foundations required are also diverse, so there are also many types of drilling and foundation construction equipment: Type, which mainly includes mobile drilling rigs for construction (torque less than 35kN·m), piles and other foundation construction equipment (including torque Drilling rigs with a capacity of not less than 35 kN·m), underground continuous wall equipment, interchangeable auxiliary equipment (such as impact hammers, pile pullers, vibrating hammers, vibrators, rotary Rotary impact power head, rotary drilling power head, etc:) and jetting, grouting and grouting equipment: GB/T 43746 is intended to consist of three parts: --- Part 1: General requirements; --- Part 2: Mobile drilling rigs for construction; --- Part 3: Piles and other foundation construction equipment: GB/T 43746:1 gives the general safety requirements for all types of drilling and foundation construction equipment mentioned above, and gives the general safety requirements for spraying in Chapter 8: Supplementary safety requirements for injection, grouting and grouting equipment, and in Chapter 9, supplementary safety requirements for interchangeable auxiliary equipment are given; GB/T 43746:2 gives the additional safety requirements for mobile drilling rigs used in construction; GB/T 43746:3 gives the additional safety requirements for pile and other foundation construction: Supplementary safety requirements for underground continuous wall equipment: Supplementary safety requirements for underground continuous wall equipment are expected to be given by other standards other than GB/T 43746: These additional safety requirements supplement or modify the requirements for the specific types of drilling and foundation construction equipment they cover: The general safety requirements in GB/T 43746:1 (except Chapter 8 and Chapter 9) are intended to be consistent with Chapter 8 and Chapter 9 of GB/T 43746:1, GB/T 43746:2, GB/T 43746:3, one or more of the other standards expected to be related to supplementary safety requirements for underground continuous wall equipment Used in combination: For multi-purpose machines, GB/T 43746 includes all parts of its specific functions and applications (including Chapter 8 of GB/T 43746:1 and Chapter 9) and other standards concerning additional safety requirements for underground continuous wall equipment: For example, a drill that can also be used as a pile driver Machines must comply with the relevant requirements of GB/T 43746:1, GB/T 43746:2 and GB/T 43746:3: Drilling or foundation construction equipment intended to be permanently fixed on the chassis of earth-moving machinery, agricultural machinery or cranes, the whole machine It must comply with the requirements of GB/T 43746: GB/T 43746:1~GB/T 43746:3, including Chapter 8 of GB/T 43746:1 and the expected supplementary provisions on underground continuous wall equipment Drilling and foundation construction equipment within the scope of other standards for safety requirements can be interchangeable with the accessories described in Chapter 9 of GB/T 43746:1: Equipment that is an integral part of the whole machine or can be installed interchangeably: Drilling and foundation construction equipment must meet the following requirements if it is intended to be used in potentially explosive atmospheres or where there is a risk of lightning: Other requirements not included in GB/T 43746: In order to balance the document structure, GB/T 43746:1 sets up Appendix A to Appendix L to provide additional information and text that are helpful for the use of this document: supplementary or additional terms: --- Appendix A gives a list of drilling and foundation construction equipment to guide the identification of various
