Problems solved by technology

[0002] At present, most of the underground structures under construction or completed in China are cast-in-place. However, the traditional cast-in-place method has disadvantages such as long construction period, great impact on the surrounding environment of the project, and high labor intensity. The prefabricated assembled structure is produced through factory production. , Assembled construction is more and more widely used. When encountering time-limited and highly sensitive foundation pit projects, the use of modular construction can meet the timeliness requirements while ensuring safety and quality

Embodiment Construction

[0030] In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 3 As shown, the present invention provides a large base plate modular structure under time-limited conditions, including:

[0032] A plurality of prefabricated large base plates 2 arranged in the underground continuous wall 1;

[0033] The post-casting belt 3 is arranged between the prefabricated large base plates 2 of the adjacent blocks, and the overhanging steel bars of each prefabricated large base plate 2 extend into the post-casting belt 3, and the overhangs of the adjacent two prefabricated large base plates 2 extend into the post-casting belt 3. Rebars are connected to each other;

[0034] The pile body of the cast-in-place pile 4 arranged at the lower part of the post-casting zone 3, the rein...

Abstract

According to the large bottom plate modular structure under the time-limited condition and the construction method, the construction processes of pile head rapid breaking, prefabricated cushion layer close splicing, pre-paving and anti-sticking high-molecular polymer waterproof coiled material construction, pile plate waterproof joint connection design, UHPC post-pouring connection and the like are adopted; and finally, a set of efficient, stable and safe modular construction system for the large bottom plate is formed. According to the splicing structure using the prefabricated splicing bottom plate, the prefabricated splicing bottom plate of the underground structure is stably connected with the bottom pile, the structure stress is complete, and meanwhile the good waterproof effect is achieved.

Description

technical field [0001] The invention relates to a large-slab modular structure and a construction method under time-limited conditions. Background technique [0002] At present, most of the underground structures that are under construction or have been built in China are cast-in-place, but the traditional cast-in-place method has disadvantages such as long construction period, great impact on the surrounding environment of the project, and high labor intensity. , Assembly construction is more and more widely used. When encountering foundation pit projects with limited time and high sensitivity, modular construction can meet the requirements of timeliness while ensuring safety and quality. Therefore, how to use prefabricated components for the construction of the large base plate has become a difficult problem that needs to be studied and solved urgently. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a large base plate modular struct...
