According to the requirements of the exposure draft, the construction unit shall organize the investigation of underground pipelines before construction, provide the construction unit with underground pipeline data at the construction site and adjacent areas, and ensure the authenticity, accuracy and integrity of the data.
In order to ensure the normal operation of construction and the safety of underground pipelines, and further strengthen the prevention of accidents of construction damaging underground pipelines, the Municipal Urban Management Committee drafted the measures of Beijing Municipality for the protection of underground pipelines during construction (Draft for comments), and recently solicited opinions from the society.
During on-site operation, the construction shall be carried out in strict accordance with the established construction scheme and special protective measures for underground pipelines.
If there are underground pipeline accidents caused by construction failure of relevant units or personnel in one year, they shall not be included in the selection scope of excellence evaluation, bidding and so on…
The draft proposed that all relevant implementation entities should carry out and implement the construction operation, protect underground pipelines, and consciously accept relevant supervision and management.
Administrative organs at all levels, enterprises and institutions shall consult the Beijing underground pipeline accident information database during the organization of excellence evaluation, bidding and other work.
Clarify the responsibilities of the main body for the implementation of construction operations.
The construction unit shall log in or go to the sub District Office (Township People’s Government) of the construction site by itself at least 7 days before the construction of the construction project (except emergency repair project) on the basis of fully considering the needs of docking with the pipeline unit in the preliminary work of project site selection, survey and design, capital budget and other aspects Log in to Beijing underground pipeline safety protection information system (hereinafter referred to as “pipeline protection system”) at the designated place, release the construction operation information as required, and do a good job in the follow-up operation and information filling in the system.
The draft for comments drafted this time is applicable to the demolition and construction of houses, the construction, reconstruction and expansion of roads and bridges, the construction, maintenance and reconstruction of underground pipelines or underground structures, as well as drilling, piling, well drilling, ramming, pit excavation, soil borrowing, rod embedding, blasting, jacking, stacking and other types of damaged roads Protection of underground pipelines and related supervision and management activities during soil construction.
Relevant units involved in the accident will be jointly punished.
Beijing plans to establish an underground pipeline construction notification system.
The exposure draft makes it clear that if the construction unit, construction unit, supervision unit and pipeline unit fail to comply with relevant regulations, resulting in the accident of damaging underground pipelines or causing losses, they shall be investigated for compensation according to law.
The competent authorities shall, in accordance with their functions and powers and relevant laws and regulations, stop production and business for rectification, revoke the administrative license, reduce the qualification level Joint punishment shall be implemented by measures such as revocation of qualification certificate, suspension or cancellation of bidding qualification, suspension of practice, revocation of practice qualification certificate, etc.
Mechanical excavation is prohibited within the safe clear distance of existing underground pipelines (not less than 1m, within 5m on both sides of the central line of oil and gas pipelines); Before mechanical excavation, conduct manual pit (ditch) exploration.
Before entering the construction site, the construction unit shall organize the survey and design unit to connect with the pipeline unit on matters related to the protection of underground pipelines, indicate the key parts and links related to the protection of underground pipelines in the survey and design documents, put forward measures and suggestions, and carry out special design if necessary; During operation on the construction site, once the underground pipeline whose actual situation is inconsistent with the data is found, the construction shall be suspended immediately, the relevant pipeline unit shall be notified to verify and confirm on site, cooperate with the pipeline unit to organize exploration and supplementary survey, and the construction can be continued only after the data and relevant underground pipeline protection measures are improved.
The construction operation information shall be released at least 7 days in advance.
In recent years, accidents of underground pipelines damaged by construction in the city have occurred frequently, which has seriously affected the safety and stability of the capital city and the production and life of citizens.
Before entering the site, the construction unit shall carry out construction activities with high risks such as earth excavation (where the depth exceeds 3M, the depth does not exceed 3M but the underground pipeline is complex), underground concealed excavation (mining method, shield method, pipe jacking method or box culvert jacking method), blasting, pile foundation and open fire, as well as oil and gas pipelines, urban gas high-pressure pipelines For the construction section of the underground comprehensive pipe gallery, a special construction scheme shall be prepared, which shall be approved by the pipeline unit and submitted for approval in accordance with the national and municipal safety management regulations on divisional and subdivisional works with high risk.
For all construction operations that may endanger the safety of underground pipelines, the construction unit shall log in to the Beijing underground pipeline safety protection information system before construction to inform the project location, excavation method, construction time and other information.
It is proposed in the exposure draft that mechanical excavation is prohibited within the safe clear distance.
After the construction unit releases the construction operation information, the pipeline unit shall feed back whether the pipeline is involved in the pipeline protection system within 2 days.
According to the content of the exposure draft, underground pipelines include municipal infrastructure such as gas supply, heating, water supply, rainwater, sewage, reclaimed water, power, lighting, communication information, radio and television, public security and transportation, underground pipelines and ancillary facilities, hazardous chemical transmission pipelines, oil and gas long-distance transmission pipelines, water transmission pipe culverts of South-to-North Water Transfer Underground comprehensive pipe gallery and ancillary facilities.
The municipal urban management department shall collect the accidents of underground pipelines damaged by construction in the whole city, regularly expose the case information to the public through the news media and the Internet, and report it to the relevant competent authorities.
The municipal urban administrative department shall establish an information database of accidents of construction damage to underground pipelines in the whole city, and record the performance of the construction unit, construction unit, supervision unit and pipeline unit to protect underground pipelines during construction.
