Embodiment Construction
[0029] The specific technical solution is: provide a method for laying the hangar floor on soft soil foundation, including the steps of laying the hangar floor at the gate section and the hangar floor at the fence section: and laying the hangar floor at the gate section and the hangar floor at the fence section The floor is laid at the same time or time-sharing;
[0030] Laying of the hangar floor at the gate section
[0031] Build support piles on the soft ground, cast cap beams on the support piles, and lay gate tracks on the cap beams. The width of the bearing surface of the cap beams is greater than the width of the gate tracks, so that the cap beams and gate tracks A step structure is formed in the width direction; a layer of polyvinyl fluoride is laid on the step surface of the step structure, and a steel mesh is laid from the polyvinyl fluoride layer, and the steel mesh includes upper and lower layers, and then concrete is cast, Forming the reinforced concrete hangar f...

The invention relates to a novel making method for an aircraft hanger floor structure with a soft soil foundation, namely a paving method for an aircraft hanger floor with a soft soil foundation. Compared with the traditional making method, the paving method can be used for solving or eliminating the problems caused by consolidation settlement of the soft soil foundation, and the problems are as follows: (1) hanger entering or exiting of an aircraft is seriously influenced by a step formed between the aircraft hanger floor and a door ground rail; (2) underground pipelines for enclosing a structural wall and traversing the wall are destroyed and cracked; and (3) the using function such as drainage of the aircraft hanger floor is influenced because the aircraft hanger floor is shaped like a pan bottom. The floor is designed to be supported on an aircraft hanger door ground rail beam and a foundation beam in a hinged way; the floor is properly thickened within a certain range, and a double-layer two-way reinforcement fabric is configured to reinforce the floor; temperature expansion joints are arranged between the aircraft hanger floor and the aircraft hanger door ground rail beam and between the aircraft hanger floor and the foundation beam, and discrete materials such as pitch and hemp are filled between the joints; and the aircraft hanger floor is provided with a 0.2-0.5% gentle slope from the central point to the circumference.
Description
[0001] Technical field: [0002] The present invention relates to a new type of hangar floor construction method on soft soil foundation, that is, a method for laying hangar floor on soft soil foundation. Compared with the traditional method, it can solve or eliminate settlement due to consolidation of soft soil foundation, 1) The steps formed between the hangar floor and the ground rail of the gate seriously affect the aircraft entering and leaving the warehouse; 2) The wall of the enclosure structure and the damage and cracking of the underground pipeline passing through the wall; 3) The hangar floor forms a pot bottom shape , thus affecting the use functions such as hangar floor drainage. [0003] Background technique: [0004] Coastal cities such as Shanghai, Tianjin, and Xiamen are important civil aviation aircraft manufacturing bases and maintenance bases in my country. Large civil aviation aircraft manufacturing and maintenance hangars have heavy ground loads and strict...
