Shanghai strong foundation typeSteel composite support technology has the advantages of short construction period, low cost and large space. Using prestressed fish belly beam structure, also known as prestressed fish bellytypeSteel support for foundation pit. At the same time, strictly control the construction quality and standardize the construction technologyIn order tosecurityandThe quality ofAs the number one, strictly monitor the deformation of foundation pit support. Foundation pit support monitoringIt mainly includes the following points :

(1)The deformation monitoring of the internal support system of tool assembly is usually carried out simultaneously with the foundation pit monitoring, and the monitoring content includes the change of the axial force of the member.

(2) component axial force monitoring:inThe main stress points of the prefabricated steel support members are directly arranged with string reaction meters or strain gauges, and the deformation stresses are integrated through conduction cables to monitor the frequency normally1 ～ 2time/Oh, my God, under unusual circumstances3 time～ 6 time/Days.

(3) The professional analysis of monitoring results shall be timely notified to all parties, and the process shall be continuously monitored until the end of foundation pit excavation and the structural concrete reaches the predetermined strength. Control the alarm value in strict accordance with the design indicators.
