The bridge generally consists of an upper structure, a lower structure and an auxiliary structure, wherein the upper structure mainly refers to a bridge span structure and a support system; the lower structure comprises a bridge abutment, a bridge pier and a foundation; the auxiliary structures refer to bridge end butt straps, tapered revetments, diversion works and the like. Because the substructure often has the characteristics that the structure is hidden, the corrosive environment is complicated, and the operation risk is high, the substructure belongs to an irreplaceable component in each structure of the bridge, and is easy to become a blind area for managing and maintaining.

The steel sheet pile cofferdam is the most common sheet pile cofferdam, and a waterproof barrier is formed by inserting and beating special-shaped steel plates. Although the steel sheet pile cofferdam is simple and convenient to construct and low in manufacturing cost, the construction and maintenance history of in-service bridges is often complex, and island building materials in the construction period and throwing materials in later-stage scouring protection may remain near piers, so that the steel sheet pile cofferdam cannot be driven into the bottom of a seabed. In addition, a certain construction operation space is needed for inserting and driving the steel sheet piles, the limitation of bridge clearance is caused, and the working space of the steel sheet pile cofferdam pile driver is insufficient. Because the lower structure of the bridge is an existing structure, the traditional steel boxed cofferdam cannot adopt the construction operation procedure from bottom to top in the construction period in the construction process, and needs to adopt the step of setting up a temporary construction platform to sink the steel boxed cofferdam in sections. For a high pile cap in a deep water area, a steel sleeve box with enough height is needed to realize the effect of bottom water sealing. In addition, the interference of the pile foundations is received, and the bottom sealing concrete pouring quality in the area range between the pile foundations is difficult to guarantee.

TABLE 1 corresponding relationship table of lateral water pressure and water head height suffered by rubber belt 3.3
Due to Pw≥α*P0At this time, the parameter point in fig. 7 is located below the regression curve, and at this time, the sealing of the rubber belt 3.3 fails and a leakage phenomenon occurs, so that the lateral water pressure P of the rubber belt 3.3wStress P on initial contact surface0There is a critical relationship between:
Pw＝α*P0 (1)；
where α is a constant related to the material of the rubber belt 3.3. For example, when the material of the rubber tape 3.3 is a non-swelling elastic rubber, α is about 1.3.
Assuming a maximum head height H, the lateral water pressure P of the rubber band 3.3 is thenwComprises the following steps:
Pw＝ρ*g*H (2)；
thus, the minimum contact surface boundary stress F of the rubber belt 3.3 can be obtained according to the formula (1) and the formula (2)0：
F0＝P0*B*1＝Pw*B/α＝ρ*g*H*B/α (3)；
Wherein B is the cross-sectional width of the rubber band 3.3.
Therefore, as shown in fig. 6, the thrust T that the telescopic driving member 3.1 needs to apply to the rubber belt 3.3 can be calculated according to the force-bearing mode of the multi-point support continuous beamiWherein i is a natural number.
