Check the dam slope protection construction site. During the inspection, the following problems were found: (1) When the cushion screen residue was laid, it was discharged from the top of the dam to the toe of the slope, resulting in particle size separation, and large stones were concentrated at the toe of the slope, which was not conducive to the slope protection construction of concrete precast blocks; (2) The thickness of sieve residue in some cushion layers is uneven, and the compaction control is not carried out; (3) The maintenance of mortar masonry at the toe of slope is not timely; 2. There are some problems in the construction site of dam construction and spillway in river section: (1) The division of materials in dam filling is not straight enough; (2) The joint between drainage sand belt and clay impervious body is constructed with clay blocks, which are uneven; (3) During the prefabrication of spillway bridge, the formwork and concrete vibrating construction should be strengthened when bubbles and roots at the bottom of the beam escape; 2. Project acceptance 1, participated in the foundation excavation acceptance of surge shaft of water conveyance tunnel and tailrace pool of power station; 2. Participate in five acceptance tests in the second half of the year, such as foundation excavation of concrete wing wall at spillway entrance and excavation of tailwater slope; 3. 1 person participates in the cleaning and acceptance of the right bank slope of the third bid section of the dam; Three. Quality and data inspection 1 and 03.3 1 participated in the safety inspection organized by the Construction Management Bureau. 2.04. 1 1 The supervisor organizes relevant personnel to conduct self-inspection on the materials of the supervision department. 3.04. 12 participated in the quality inspection organized by the Construction Management Bureau, mainly to check the quality of the construction site and engineering entities. On 4.04. 17-04.23, the project station conducted spot checks on the construction quality evaluation and quality inspection data of eight major construction units and third-party laboratories. Iv. Attend the on-site meeting 1, 04.05438+0 Vice Minister of Water Resources Hu Siyi and his party inspected the site. 2. Attend the supervision meeting and construction technical disclosure meeting, and discuss the technical requirements of concrete precast block slope protection construction for 5 times; It was emphasized at the meeting (1) that the dam slope protection construction should be strictly checked and accepted; (3) All units should strengthen the collation and summary of completion data; (2) Strengthen the research on mandatory provisions and quality control; V. Project preparation 1. According to the progress and acceptance plan of Yanshan Reservoir project, combined with the actual situation of the project and the feedback from various units, the quality supervision work plan of Yanshan Reservoir project in 2007 was issued with the approval of the main station. 2. In 2007, the first quality supervision bulletin was compiled. This month's project quality problems are handled in 1. The problems found in the on-site inspection shall be promptly notified to the supervisor and the person in charge of the on-site construction for rectification, and oral notification shall be made at the regular production meeting. 2. Organize a quality symposium with the Construction Management Bureau and the Supervisor. (1) urge and suggest all construction units to timely file and sort out the construction quality inspection data according to Table 04 of "Sample Form Filling", and fill in the quality report according to the unified form, which is required to be submitted to the project station for verification before May 10. (2) Elaborated the compilation method of building appearance quality evaluation standard, and put forward the requirements. (3) The evaluation criteria of quality evaluation table for slope protection unit on dam surface are discussed. 3. Spot-check the construction quality evaluation and quality inspection data of eight units, and issue a notice of inspection results (Yan Quality Supervision [2007] No.02), requiring contractors to rectify in time.
