And the end parts of the supporting steel bar units of the supporting steel bars are respectively fixed on the section line of the longitudinal section of the steel cylinder.
The supporting steel bars comprise oblique steel bars, and the oblique steel bars and the right angle of the section line of the longitudinal section of the steel cylinder form a triangular structure.
The outer diameter of the compression spring is smaller than the inner diameter of the steel cylinder.
A construction method of a steel plate and steel cylinder connecting component containing a spring comprises the following steps:

s4: and (3) putting the horizontal part of the steel cylinder in the direction of the inclined steel support, and connecting the inclined steel support and the steel cylinder by using steel plate adhesive.
The invention has the beneficial effects that:
1. the invention increases the stress and the axial force bearing strength of the joint through the compression spring, and the steel cylinder for placing the compression spring and the supporting steel bars inside ensure that the tension of the compression spring does not act on the inclined steel support so as to damage the inclined steel support; an inclined steel bar is arranged at the right-angle support of the steel cylinder to form a triangular structure, so that the stability in the member is further improved; when the supporting system is subjected to a large stress load, the upward tension of the compression spring provides extra support; when the supporting system is subjected to a large axial force load, the outward tension of the compression spring provides extra support, so that the bearing capacity of the whole foundation pit supporting system is improved. In addition, the compression spring is not connected with the steel cylinder, so that the compression spring has certain degree of freedom in the steel cylinder, and the compression spring can play a role more flexibly; and the size of the steel cylinder also limits the unconstrained movement of the compression spring, so that the normal function of the compression spring is ensured.
