The structural strengthening project of Building 4 # of Beijing Yizhuang Backup Center is located at No. 137, Jinghai 3rd Road, Beijing Economic and Technological Development Zone. It has five floors above the ground and six floors locally. After reconstruction, it will be used as a data room, with an overall elevation of 24.6m and floor height of 4.75m for the first floor, 4.2m for the second to fourth floors, 4.25m for the fifth floor and 3.3m for the sixth floor locally. Demolition shall be carried out according to the need of reinforcement. The frame column of the original floor shall be reinforced with steel, and the adjacent ground around the frame column (reinforced concrete cushion plus pea gravel concrete surface course) shall be demolished; Demolition of secondary structure wall (mixed structure) obstructed by partially reinforced frame column edge; Remove the painting layer of frame column decoration; Removal of reinforced frame column angle steel through floor slab opening; Dismantle the pipeline of central air-conditioning system and equipment (fan coil unit) fire fighting system, fire hydrant box and wire bridge obstructed by reinforced frame column; The reinforced frame column goes out of the roof insulation layer, slope making and waterproof removal of the protective layer Dismantle the construction of sticking carbon fiber cloth under the roof. Dismantle the rainwater pipe, central air-conditioning system pipeline and equipment (fan coil unit), fire control system pipeline, fire hydrant box, wire bridge under the original floor; Demolition and polishing of suspender and hanger shall be flat with the floor; Polish and repair the concrete surface under the plain floor slab; Floor opening and plugging; Remove and clean the painting layer under the original local board surface Demolition is related to the position where the frame beam of the barrier floor is bonded with steel for reinforcement, and the secondary structural wall (mixed structure) below the partially reinforced frame beam is demolished. The scope of demolition meets the beam reinforcement construction; Reinforce the edge rainwater pipe central air conditioning system pipeline, fire system pipeline and wire bridge that are obstructed under the frame beam; Reinforce the frame beam. On the fifth floor slab, stick the steel to strengthen the roof insulation layer. Slope making protective layer waterproof removal. After the removal of the stairs related to the 4-6/C-D axis of the composite floor slab, the composite floor slab construction. Due to the particularity of the construction site, the removal is to ensure construction safety, reduce construction noise, reduce dust pollution, and maximize the environmental impact in the construction area, At the same time, ensure the normal living requirements in the construction area. After study, our company has decided to adopt mechanized demolition as the main method, and the demolition will be carried out manually. The specific organization and implementation of the project are as follows:

Construction Scheme for Steel Beam Reinforcement of Clubhouse（ word Format)
(1) This project is the steel structure reinforcement project of the 30th and 31st floors of the Bund Club. As the functions and layout of each floor of the building have changed from the original building plane, it is necessary to make holes in the concrete floor and the original steel beam web. According to the design institute's new building functions, the entire structure is calculated and analyzed as a whole, and the original structural steel beams are strengthened. Stiffeners are added around the holes on both sides of the steel beam web and welded firmly with the steel beam. ⑵ Material requirements for design transformation: ① Steel: steel plate and profile steel shall be Q345 grade B low-alloy high-strength structural steel, and the connection method shall be welding. The welds manually welded on site shall meet the requirements of Class II welds. The exposed surface of steel shall be painted with antirust paint and anti-corrosion finish paint. ② Reinforcement of floor holes: 20mm thick steel plates are used around the holes to connect with the original concrete floor bolts. ③ Chemical anchor bolt: the new steel plate is connected with the original concrete structure. When the steel plate is bonded for reinforcement, the domestic M14 chemical anchor bolt is used to fix the steel plate.

Construction scheme of snow shelter steel structure （ word Format)
Changping Line of Beijing Rail Transit is a north-south high-speed passenger rail transit line connecting the central urban area and Changping New City. The line starts from the Ming Tombs Scenic Area in the north and ends at Xierqi Station of Line 13 in the south, with a total length of 31.7km, including 15.5km of overhead line, 13.2km of underground line and 3.0km of ground line. According to the relevant requirements of the construction unit that "in order to meet the needs of operation safety, it is required to install snow proof sheds at the turnout of Changping Line and other places", the project needs to set snow proof sheds in some turnout areas of the elevated line, and the design form of the snow proof sheds is consistent with the sound barrier. In addition, considering that some snow shelter locations may have the need to set up a fully enclosed sound barrier in the later period, it is required to select the partition of each part of the snow shelter at sections with noise sensitive points, which should meet the technical performance requirements of the sound barrier profession at the same time to avoid secondary replacement in the later period; For the road section without noise sensitive points, the snow proof baffle without sound insulation and absorption function can be properly selected.

Construction scheme of industrial reservoir （ word Format)
The construction coordinates of the industrial reservoir structure are the building coordinates of the power plant, ± 0.00m is equivalent to the 1985 national elevation datum of 570.40m, the elevation is in meters, and other dimensions are in millimeters. The project is located on the east side of the newly built demineralized water tank and the north side of the comprehensive water pump house. Six domestic fire and industrial reservoirs are arranged in a rectangular double row layout. The size of each reservoir is 31.225m * 29.4m, the net height is 5.0m, and the storage capacity of each reservoir is about 4000m3. The foundation of the project adopts natural foundation, and the foundation bearing stratum is strongly weathered mudstone. During earthwork excavation, the foundation soil shall be excavated 0.5m away from the elevation of the foundation base, and the natural state of the bearing stratum shall be maintained. After the excavation is completed, the strongly weathered mudstone bearing stratum exposed to the air shall be immediately sealed with 300 mm thick C20 plain concrete and padded to the base elevation. The project adopts reinforced concrete structure, the foundation cushion is C20 concrete, the pool body concrete is C40, the impermeability mark of the pool concrete is W8, the frost resistance mark is F150, the HPB3O0 first grade rebar is used when the rebar diameter is ≤ 10, and the HRB400 third grade rebar is used when the diameter is>10. The thickness of the reinforced concrete protective layer of the bottom plate and side wall of the pool is 50mm, the thickness of the reinforced concrete protective layer of the column and top plate of the pool is 35mm, and the thickness of the rest is 30mm.
