Buried butt joint device for sewage pipeline

Abstract

The invention discloses a buried butt joint device for a sewage pipeline, and relates to the field of civil engineering equipment. The buried butt joint device for the sewage pipeline comprises a rotating base, a horizontal movement mechanism, a vertical movement mechanism, a linear movement mechanism and an inner supporting mechanism, the inner supporting mechanism is provided with a plurality of contact heads arranged in the circumferential direction and a power unit for driving the contact heads to do expansion and contraction movement, the inner supporting mechanism is installed on the linear movement mechanism, and the power unit drives the contact heads to do expansion and contraction movement. The linear motion mechanism is installed on the horizontal motion mechanism, the horizontal motion mechanism is installed on the vertical motion mechanism, and the vertical motion mechanism is installed on the rotating base. Compared with a method for directly butting the sewage pipe to the sewage well by operating hoisting equipment in the prior art, the method has the advantages that a guiding effect is added, and the sewage pipe can be butted with the sewage well more quickly and accurately.

Description

technical field [0001] The invention relates to a buried butt joint device for sewage pipes, which relates to the field of civil engineering equipment. Background technique [0002] In the construction of urban sewage treatment system, the sewage well adopts floor-to-ceiling brick structure in the conventional construction process. The construction sequence is to lay the sand cushion at the bottom of the foundation trench after excavating the foundation trench. Pouring; then use machinery to hang the sewage pipes, and then build sewage wells to connect the sewage pipes on both sides. The advantage of this process is that the construction area is small and the restrictions of the surrounding conditions are less, but the disadvantage is that the construction period is long. Therefore, the sewage wells gradually adopt prefabricated concrete sewage wells, that is, after the sewage wells are poured in the factory as a whole, the construction site directly lifts the sewage wells i...

[0002] In the construction of urban sewage treatment system, the sewage well adopts floor-to-ceiling brick structure in the conventional construction process. The construction sequence is to lay the sand cushion at the bottom of the foundation trench after excavating the foundation trench. Pouring; then use machinery to hang the sewage pipes, and then build sewage wells to connect the sewage pipes on both sides. The advantages of this process are that the construction area is small and the surrounding conditions are less restricted, but the disadvantage is that the construction period is long

Therefore, the sewage wells gradually adopt prefabricated concrete sewage wells, that is, after the sewage wells are poured in the factory as a whole, the construction site directly lifts the sewage wells into the foundation pit, then lifts the sewage pipes and controls the sewage pipes to connect to the sewage wells through the lifting equipment The advantage of this construction technology is that the construction period is short, and the disadvantage is that it is difficult to connect the sewage pipes and sewage wells.
