[0007] Preferably, connection holes are provided on the fixing frame and the supporting steel sheet piles.

[0008] Preferably, a connecting rod is provided on the fixing frame, and a pad is provided on the connecting rod.

[0009] Preferably, a connecting hole is provided on the backing plate, and the diameter of the connecting hole matches the diameter of the connecting rod.

[0010] Preferably, the fixing frame is provided with ribs for strengthening the support of the fixing frame to the platform.

[0011] A construction method for an auxiliary device for supporting the top of a steel sheet pile in trench construction:

[0012] The fixing frame is arranged on the platform, the connection holes opened on the fixing frame, the connection holes opened on the supporting steel sheet piles and the connection holes opened on the pad are aligned, and the connecting rod is passed through to connect the platform and the supporting steel sheet piles.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the auxiliary device for supporting the top of the steel sheet piles in trench construction increases the working surface during trench excavation. The crawler tracks of the excavator must all fall on the supporting steel sheet pile top device to avoid overturning of the construction machinery. The trench support width must take into account the track gauge of the machine used. When the trench width is adjusted, the model of the construction machinery is also adjusted accordingly.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-2As shown, the present invention provides a technical solution: an auxiliary device for supporting the top of steel sheet piles for trench construction, which is arranged on the supporting steel sheet piles 6, in order to expand the supporting area of ​​the excavator, ensure that the excavator can work normally, and avoid the overturning of the construction machinery, including: a platform 1 arranged on the supporting steel sheet piles 6, the platform 1 is a mechanical walking platform, made of steel plates, and sufficient strength must be guaranteed to prevent deformation. The setting of the platform 1 must take into account the track gauge of the machinery used on site, the groove width adjustment, and the construction machinery model. The platform 1 is mainly used to support the excavator, so as to facilitate the movement and normal use of the excavator. A fixing frame 2 is provided on the platform 1. The fixing frame 2 is a channel steel column with connecting holes at the bottom for fixing and supporting the steel sheet piles 6.
