The invention discloses a semi-slotted pipe jacking supporting and jacking device for a large-caliber municipal drainage pipe. The semi-slotted pipe jacking supporting and jacking device comprises a bottom plate, a supporting plate, a roller shaft and a sliding seat. When the semi-slotted pipe jacking supporting and jacking device for the large-caliber municipal drainage pipe is used, firstly, the device is placed into a pre-excavated pit through the cooperation of a connecting piece and a lifting hole, then a motor is controlled to start to work through a switch, the motor drives a threaded shaft to rotate, the threaded shaft drives a sliding block to slide in a contraction groove through a threaded sleeve, the sliding block drives a foot pad to abut against the ground, so that the height position of the bottom plate is adjusted; meanwhile, the bottom plate is stably placed by observing a horizontal bubble, the top surface of the roller shaft on the sliding seat is flush with the bottom surface of the pre-buried position of the drainage pipe, and thus the adjusting work of the bottom plate is completed; and then a second electric cylinder is controlled to start to work through the switch, and the inclination angle of the supporting plate is adjusted under the action of a first hinge seat, a second hinge seat and a third hinge seat.
Description
technical field [0001] The invention relates to the field of municipal engineering construction, in particular to a supporting jacking device for semi-slotted pipe jacking of large-diameter municipal drainage pipes. Background technique [0002] With the development of society, the construction environment of urban municipal projects is becoming more and more complex, and there are more and more large-diameter pipes. The construction technology of semi-grooved pipe jacking has many advantages compared with traditional construction methods, not only improving the construction progress , The quality also ensures the safety of the construction, and has been widely used in municipal engineering. Nowadays, semi-grooved pipe jacking is a common technology for laying large-diameter pipes. Working slots for easy installation and use of equipment. [0003] However, the existing semi-slotted pipe jacking equipment usually uses a suspension method to locate and jack the embedded pipel...
