CJ/T 233-2016Building area drainage plastic inspection wells (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard instead of CJ/T 233-2006 "plastic drainage wells for construction inspection wells" this standard is CJ/T 233-2006 "building drainage plastic inspection wells" revision, compared with the CJ/T 233-2006 main Technical changes are as follows.

--- Modify the scope of inspection wells (see Chapter 1);

--- Added borehole ID code connected with ID pipe (see 4.3);

--- Modify wellhead axial load performance requirements (see 6.1.6);

--- Increase the inspection well system performance requirements (see 6.5);

--- Increasing the size of the wells of different specifications diameter Sediment chamber size requirements (see 6.1);

--- Increasing wellhead and wellbore connection socket should have 360 ° steps, the bottom of the well should be set to support the requirements of a stable structure (see 6.1);

--- Increase the borehole and ID logo buried pipeline connection socket size requirements for the diameter (see 6.1);

--- Remove the inspection wells and wellbore adhesive connection socket (see 2006 version 7.4);

--- Adjust the connection between wellbore and pipe joints without socket elastic seal the minimum length of the socket (see 6.1);

--- Increased pavement rain outlet positive, lateral socket structure (see Appendix B);

--- Increasing the inspection wells connected buried pipe socket and pipe clearance requirements (see 6.1);

--- Increasing the diameter of the plastic cover seat hole center hole diameter requirements and the same borehole, modified some of the plastic cover size parameters, at the same time Increase the requirements of the corresponding bearing mark on the manhole cover (see Appendix C);

--- Added anti-man fall device requirements (see Chapter 4);

--- Increased square covers and size requirements (see Appendix C);

--- Transition joint product map made the corresponding changes (see Appendix B);

--- Added another Minggou gutter product map (see Appendix B).

This standard proposed by the Ministry of Housing and Urban Standard and Design Institute.

This standard by the Ministry of Housing and Urban Water Supply and Drainage Standardization Technical Committee building centralized.

1 Scope

This standard specifies the construction area drainage plastic inspection well structure, classification and marking, materials, requirements, test methods, inspection rules, standard Log, packaging, transportation and storage.

This standard applies to the construction area (residential area, public building area, factory area, etc.), the bottom depth of the well is not more than 6m, the buried diameter is not more than 800mm drainage plastic inspection wells.
