Embodiment 1
[0047] see figure 1 and figure 2 , the present invention provides a chemical tank raft foundation reinforcement structure, embodiment 1 includes: concrete pier 1, anchor bars 5 and piles 2; concrete pier 1 is wrapped around the four corners of chemical tank raft foundation 3; concrete The pier 1 is connected to the raft foundation 3 of the chemical tank through anchor bars 5; pile holes are reserved on the concrete pier 1, and the piles 2 are inserted into the raft of the chemical tank through the pile holes reserved in the concrete pier 1 The preset depth of the foundation 3 fixes the concrete pier 1 on the ground so that the chemical grout is constructed in the structure formed by the raft foundation 3 of the chemical tank, the concrete pier 1 , the anchor bars 5 and the piles 2 .
[0048] Further, the present invention also provides embodiment 2.
[0049] see figure 1 and figure 2 , embodiment 2 includes: concrete pier 1, anchor reinforcement 5 and pile column 2; conc...
Embodiment 8
[0060] The present invention also provides a process for preparing the reinforcement structure of the chemical tank raft foundation, and embodiment 8 includes:
[0061] S1: Wrap the concrete piers around the four corners of the raft foundation of the chemical tank to obtain the four-corner concrete pier structure of the raft foundation of the primary chemical tank;
[0062] S2: Construct anchor bars in the four-corner concrete pier structure of the raft foundation of the primary chemical tank, so that the anchor bars connect the concrete pier with the four-corner bars of the raft foundation of the chemical tank to obtain a secondary chemical tank raft Square concrete pier structure with slab foundation;
[0063] S3: the piles are inserted into the preset depth of the raft foundation of the chemical tank through the pile holes on the square concrete pier structure of the raft foundation of the secondary chemical tank, and the concrete pier is fixed on the ground;
[0064] S4: ...
Embodiment 9
[0065] Further, the present invention also provides a process for preparing the reinforcement structure of the chemical tank raft foundation, and embodiment 9 includes:
[0066] 1. Before construction, do a good job of safety protection such as dust prevention and fire protection and the protection of equipment in the construction workshop; before grouting, the filling between the storage tank foundation and the adjacent foundation should be excavated to avoid grouting affecting other foundations and ground ;
[0067] 2. Foundation underpinning pier construction: at the four corners of the chemical tank raft foundation 3, excavate the underpinning pit to the original foundation soil layer; support formwork and pour C30 concrete, and reserve static pressure steel pipe piles 2 and steel anchors 5 for solidification Concrete piers overlap and wrap the corners of the raft foundation 3 of the chemical tank, and after concrete pouring and reinforcement anchorage 5 are constructed, t...
