Embodiment Construction
[0015] figure 1 Shown is the construction flowchart of the underground continuous wall of the embodiment of the present invention.
[0016] The concrete of the underground diaphragm wall in this embodiment is made of aluminate cement. The aluminate cement is made of bauxite and limestone as raw materials, and is calcined to make calcium aluminate as the main component and an alumina content of about 50%. Clinker is a hydraulic cementitious material made by grinding.
[0017] The shelf life of the aluminate cement in this example is 45 days (from the date of leaving the factory), and it is strictly forbidden to use it after the expiration date. During transportation and storage, attention should be paid to sun protection and moisture protection.
[0018] In this example, before the aluminate cement is prepared into concrete, the mixing equipment must be rinsed clean to prevent the Portland cement and lime remaining on the equipment from reacting with it and affecting the quali...

Abstract
The invention provides an aluminate reinforced concrete underground diaphragm wall easy to break in the later period. The underground diaphragm wall (1) comprises concrete, main ribs (4) of a rectangular reinforcement cage and stirrups (5). The concrete of the underground diaphragm wall is made of aluminate cement. The stirrups (5) of the reinforcement cage are independently and annularly bound instead of spirally bound. The strength of the underground diaphragm wall can be gradually reduced to 40%-50% of the highest strength after a project is completed, the underground diaphragm wall is easyto break manually or mechanically when encountering the underground diaphragm wall in later underground project construction, and the breaking difficulty of the underground diaphragm wall is greatlyreduced.
Description
technical field [0001] The invention relates to an aluminate reinforced concrete underground continuous wall which is easy to be broken later, and belongs to the technical field of civil engineering. Background technique [0002] With the rapid development of urbanization, the shortage of land has become increasingly prominent, and the development and utilization of underground space has become an important measure to solve the shortage of ground space. problems encountered. Among them, the reinforced concrete underground diaphragm wall has been widely used in the enclosure of urban subway foundation pits due to its high work efficiency, reliable quality, low vibration and low noise during construction. When the reinforced concrete underground diaphragm wall is used as a temporary structure, it will lose its original function after the completion of the project, and if it remains underground, it will inevitably affect the future development of urban underground space, such ...
