Garbage pool bottom plate and unloading platform frame column foundation settlement difference treatment system and method

Abstract

The invention provides a garbage pool bottom plate and unloading platform frame column foundation settlement difference treatment system and method. A garbage pool, a peripheral frame and an unloading platform are subjected to first-stage construction except the part of a connecting span of the unloading platform and the garbage pool; second-stage construction is conducted on the discharging platform and the garbage pool connecting span floor slab and the discharging platform and the garbage pool connecting span frame beam, and water injection pre-sedimentation treatment is conducted when the garbage pool is constructed to the preset height; the unloading platform and garbage pool connecting cross frame beam is supported at the top of a bracket on the side of a garbage pool frame column, and a rotating gap with a preset width is reserved between the unloading platform and garbage pool connecting cross frame beam and the garbage pool frame column; the unloading platform and the garbage pool connecting cross floor slab are supported at the tops of the lifting lugs on the side of the frame beam of the side wall of the garbage pool, and a rotating seam with a preset width is reserved between the unloading platform and the garbage pool connecting cross floor slab and the frame beam of the side wall of the garbage pool; according to the method, the construction period and cost of foundation treatment are saved, only the discharging platform is connected and spans in the second stage for construction in the water injection pre-pressing stage, continuous construction can be conducted in the garbage pool and other areas of the discharging platform, and the engineering construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of garbage power plants, in particular to a system and method for treating the settlement difference between the bottom plate of a garbage pond and a frame column foundation of an unloading platform. Background technique [0002] The statements in this section merely provide background related to the present disclosure and do not necessarily constitute prior art. [0003] The advantages of waste-to-energy plants are obvious. They can be used as waste and converted into electricity to supply electricity for people's production and life. They are also environmentally friendly and pollution-free. The unloading and garbage storage room is an important building in the garbage power plant. As an important structure for transporting and storing garbage, it is necessary to ensure that the harmful substances in the garbage pond are completely sealed and no leakage occurs, and the structural safety and applicability a...

Problems solved by technology

When the structure cannot resist the stress, it will lead to the destruction of the column, the cracking of the wall of the garbage pool, the fracture of the floor and the destruction of other connection nodes, and even cause the instability and collapse of the entire plant structure, resulting in engineering accidents

[0006] The connection node between the platform frame beam of the traditional unloading hall and the frame column of the garbage pool is rigidly connected, and the stressed steel bars of the frame beam of the unloading platform are anchored into the buttress columns of the garbage pool; The stressed steel bars are anchored into the side wall of the garbage pond, such as figure 2 and image 3 As shown, after the overall pouring is completed, the rotation capacity between the frame beam of the unloading platform and the wall of the garbage pool or the frame beam of the pool wall is limited

When there is differential settlement between the bottom plate of the garbage pool and the foundation of the unloading platform, since the connection is completely rigid, the rotational deformation capacity of the connecting node is limited, and a large additional bending moment and additional stress will be generated, which increases the wall of the garbage pool, The stress on the frame columns of the garbage pool, and the frame columns and beams of the unloading platform will cause cracks or even force damage and collapse of these structural components in severe cases, and harmful liquids and gases in the garbage pool will leak into the groundwater and air, destroying Ecological environment, will also cause harm to the health of nearby residents

[0007] The excessive settlement difference between the floor of the garbage tank and the foundation of the unloading platform will also cause cracks in non-structural components such as filling walls, suspended ceilings and other maintenance structures, affecting the use of the building and the appearance of the building

The excessive settlement difference between the bottom plate of the garbage tank and the foundation of the unloading platform will also cause cracking of the anti-corrosion layer and waterproof layer of the garbage tank wall. Leakage of toxic liquids into groundwater, or worse, overall structural damage

[0008] In order to eliminate the excessive settlement difference between the floor of the garbage pool and the foundation of the unloading platform, traditional methods generally use foundation treatment schemes such as cast-in-place piles and PHC pipe piles, such as Figure 4 As shown, the amount of pile foundation engineering required is huge, the construction time is long and the cost is high, which affects the overall construction period of the project and increases the project cost
