It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the utility model and not to limit the scope of the utility model.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.
As shown in figures 1, 2 and 3, a temporary door sealing structure for pipe jacking construction comprises an inner wall 10 of a pipe jacking machine, a steel sealing door 1 with the edge being in sealing connection with the inner wall 10 of the pipe jacking machine, a working hole 9 is arranged in the middle of the steel sealing door 1 and is sealed through a sealing door 2, a sealing gasket 6 is arranged between the steel sealing door 1 and the sealing door 2, and the steel sealing door and the sealing door are fixedly connected through a bolt structure.
Furthermore, a plurality of tucking angles 7 are symmetrically arranged at the junction of the steel sealing door 1 and the inner wall 10 of the push bench.
Furthermore, the tuck angle 7 is an isosceles right triangle steel plate.
Further, the bolt structure comprises bolts 4 which are vertically and symmetrically arranged on the surface of the steel sealing door 1 and bolt holes 8 which are arranged on the sealing door 2 and correspond to the bolts 4, and the bolts 4 penetrate through the bolt holes 8 and are tightly connected through nuts 3.
Further, the diameter of the bolt hole 8 is slightly larger than that of the bolt 4.
Further, the sealing door 2 and the working hole 9 are both circular, and the diameter of the sealing door 2 is larger than that of the working hole 9.
