Leakage repair and pollution of underground garage in Jiujiang County Water pipe Leakage stoppage in the tunnel and leakage repair in the basement, The waterproof grade of the basement of the project is Grade II, and three layers of waterproof are adopted. The floor and exterior wall are rigid waterproof with C30S8 waterproof concrete, and two layers of 3mm thick external waterproof are applied SBS Type III modification asphalt Waterproof roll (Flexible waterproofing), the peripheral backfill adopts 2:8 lime soil three layers of waterproofing. In order to ensure that the basement waterproof is foolproof, we should take every waterproof seriously.

(2) Setting out and leveling: according to the measurement and positioning control line, set out the cushion sideline and the position line of Houjiang belt.
(3) Make elevation control points: according to the design elevation, use cement mortar to make several elevation control points in the middle.
Requirements for leak stopping materials in basement:
(1) The project adopts premixed concrete and pump pouring; When signing the concrete supply contract with the concrete company, the following technical requirements for waterproof concrete are proposed as part of the contract: a Concrete grade: C39S8b Slump: 100-140mmc Initial setting time: 4-6 h, d. Control requirements for alkali aggregate: large chloride ion content 0.2%, large alkali content 3.0 kg/m3.
(2) Before concrete mobilization, the concrete company shall provide concrete mix proportion notice, calculation sheet of chloride ion and alkali content, concrete setting curve table and other data, which can be officially poured after being reviewed by the project chief engineer and supervision engineer.
(3) Control the quality of concrete entering the site: after the concrete enters the site, check the time of concrete leaving the machine in a timely manner, make a record of the time of starting pouring and finishing pouring, and ensure that the concrete is poured before the initial setting. During pouring, the tester shall check the slump of each truck of concrete entering the site, make records, and withdraw the unqualified concrete from the site.
Quality acceptance of basement plugging
(1) Division of inspection lot: confirm the division of inspection lot and inspection quantity with the supervisor before acceptance. According to the specification requirements: spot check every 100m2 of exposed concrete area, 10m2 for each place, and no less than 3 places; Check all details.
(2) Acceptance: see the section Management Assurance System and Quality Management Measures for details.
(3) Inspection of technical data a. Concrete certificate, impermeability test report and alkali content report provided by the concrete company.
