Revision Notes
This specification is based on the notice of the former State Construction Commission (79) Jianfa No. 168 and the former State Construction Engineering Bureau (80) No. 385, and is jointly revised by the former Sichuan Provincial Construction Commission, the former Sichuan Provincial Construction Department, the Ministry of Railways, the Ministry of Metallurgy, the Ministry of Water Resources and Electric Power, China Construction Second Engineering Bureau, China Municipal Engineering Southwest Design Institute, China Construction Southwest Survey Institute and Gansu, Hunan, Liaoning, Guizhou and other provincial construction bureaus to the national standard "Earthwork and Blasting Engineering Construction and Acceptance Specifications" GBJ4-64 (revised version).
The principles of this revision are: based on the national technical and economic policies, fully consider the current construction technology level and future development direction of our country, and strive to achieve advanced technology, reasonable economy, safety and applicability, and ensure quality. For the provisions in the original specification: those that are still applicable will be retained; those that are outdated or have great limitations will be deleted; and those that are inaccurate or unclear will be revised. New technologies or scientific research results that have been identified and promoted by the state will be supplemented, and foreign advanced technical standards that meet my country's conditions will be adopted.
During the revision process, three comprehensive investigations and studies were conducted, and opinions from the whole country were solicited twice. A preliminary review meeting and two technical seminars were held for the main issues. After the draft was revised five times, an examination meeting was held in Wuhan in October 1981, and representatives from relevant ministries and 18 provinces and cities jointly reviewed it. In June 1983, an approval meeting was held in Suzhou, Jiangsu Province to discuss the finalization of the Engineering Construction Standard Full Text Information System

Section 1 General Provisions
Article 3.1.1 Earthwork construction should be carried out with earthwork balance calculation, and the earthwork should be deployed in accordance with the shortest earthwork transportation distance, reasonable transportation distance and the construction sequence of each engineering project to reduce repeated transportation.
Earthwork deployment should be combined with local city and town planning and farmland water conservancy as much as possible.
Note: The balance calculation of earthwork should comprehensively consider various factors that change the earthwork volume, such as the looseness rate, compression rate, settlement of the soil, etc.
Article 3.1.2 When excavating earthwork, nearby existing buildings or structures, roads, pipelines, etc. should be prevented from sinking and deforming. If necessary, protective measures should be taken in consultation with the design unit or construction unit, and settlement and displacement observations should be carried out during construction.
Article 3.1.3 The surface slope of the leveled site should meet the design requirements. If there is no design requirement, a slope of not less than 2% should generally be made in the direction of the drainage ditch. The surface of the leveled site should be checked point by point, and the spacing between the inspection points should not be greater than 20m.
Article 3.1.4 During the construction of earthwork, its plane position, horizontal elevation and slope should be measured and checked frequently to see if they meet the design requirements. Plane excavation piles and leveling points should also be re-measured and checked regularly to see if they are correct. Article 3.1.5 During nighttime construction, construction projects should be arranged reasonably to prevent over-excavation or over-thickness of paving. Lighting facilities should be installed on the construction site as needed, and obvious signs should be set up in dangerous areas. Article 3.1.6 When mechanical construction is adopted, necessary slope trimming and excavation or filling of site corners and small trenches can be carried out manually or with the cooperation of small machines.
Article 3.1.7 All provisions in this chapter on backfilling and backfilling of foundation pits (trench) and pipe trenches refer to backfilling designed with compaction requirements. Section 2 Drainage and Lowering of Groundwater Level
(I) Drainage
