Abstract
The utility model discloses a kind of pipe jacking tool pipe turnover hole antipriming, include the active well borehole wall, the active well borehole wall is provided with pipe jacking tool pipe turnover hole, the hole part in pipe jacking tool pipe turnover hole mounts cover annular watertight rubber plate, on described watertight rubber plate, is pressed with annular fixation steel plate; Described watertight rubber plate and fixation steel plate are bolted on the active well borehole wall; The internal diameter of described watertight rubber plate is less than tool pipe external diameter.The utility model is simple in structure, reasonable in design, and the utility model, by watertight rubber plate sealing, can be realized and prevent that underground water from entering in active well, makes it meet engine request, and easy to use, stagnant water effect is good.
Description
technical field:
The utility model relates generally to technical field, relates in particular to a kind of pipe jacking tool pipe turnover hole antipriming.
background technology:
Along with the development of Process of Urbanization Construction, urban construction improves day by day to the requirement of environmental protection, and urban duct heavy excavation will be eliminated gradually.Urban duct and the construction of underground traffic traffic engineering will be carried forward vigorously jacking pipe construction process.In jacking construction process, hole sealing seems particularly important, and in pipe-jacking project construction, can jacking work complete smoothly, and strict to closing to the requirement of jacking active well, jacking active well leaks and can have a strong impact on progress and the quality of jacking.
utility model content:
The utility model object is exactly in order to make up the defect of prior art, a kind of pipe jacking tool pipe turnover hole antipriming is provided, so that working pit caisson wall and tool pipe and outer pipe wall water resistance are more stable, effective, thereby raise the efficiency, guarantee workmanship.
The utility model is achieved through the following technical solutions:
A kind of pipe jacking tool pipe turnover hole antipriming, include the active well borehole wall, the active well borehole wall is provided with pipe jacking tool pipe turnover hole, it is characterized in that: the hole part in described pipe jacking tool pipe turnover hole mounts cover annular watertight rubber plate, on described watertight rubber plate, is pressed with annular fixation steel plate; Described watertight rubber plate and fixation steel plate are bolted on the active well borehole wall; The internal diameter of described watertight rubber plate is less than tool pipe external diameter.
A pipe jacking tool pipe turnover hole antipriming, is characterized in that: the cross section of watertight rubber plate is L-type.
A pipe jacking tool pipe turnover hole antipriming, is characterized in that: the thickness of described watertight rubber plate is 18-22mm, the thickness of fixation steel plate is 8-12mm.
The utility model arranges bolt in the lap position of fixation steel plate and watertight rubber plate and is fixed on the active well borehole wall, described set bolt is mutually vertical with fixation steel plate, fixation steel plate and watertight rubber plate are parallel to each other, fixation steel plate is fixed on watertight rubber plate on the borehole wall by bolt, watertight rubber plate internal diameter is less than fixation steel plate internal diameter and tool pipe external diameter, and tool pipe enters the scope of operation by watertight rubber plate.
The utility model has the advantages that:
The utility model is simple in structure, reasonable in design, and the utility model, by watertight rubber plate sealing, can be realized and prevent that underground water from entering in active well, makes it meet engine request, and easy to use, stagnant water effect is good.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
the specific embodiment:
Referring to accompanying drawing.
A kind of pipe jacking tool pipe turnover hole antipriming, include the active well borehole wall 5, the active well borehole wall 5 is provided with pipe jacking tool pipe turnover hole, and the hole part in described pipe jacking tool pipe turnover hole mounts cover annular watertight rubber plate 1, on described watertight rubber plate 1, is pressed with annular fixation steel plate 2; Described watertight rubber plate 1 and fixation steel plate 2 are fixed on the active well borehole wall 5 by bolt 4; The internal diameter of described watertight rubber plate 1 is less than tool pipe external diameter.
The cross section of watertight rubber plate 1 is L-type.
The thickness of watertight rubber plate 1 is 20mm, and the thickness of fixation steel plate 2 is 10mm.
Bolt 4 is expansion bolt.Before installation, first watertight rubber plate 1 is pressed in to hole part, shimming on bolt 4, is loading onto fixation steel plate 2, and fixation steel plate 2 is fixed on watertight rubber plate 1 on the borehole wall by bolt 4; Watertight rubber plate internal diameter is more smaller than fixation steel plate internal diameter and tool pipe external diameter; Tool pipe enters the scope of operation by watertight rubber plate, and watertight rubber plate inner side (L) profile and tool pipe and pipeline outer wall are combined closely, and play sealing effect.
In concrete enforcement, fixation steel plate adopts the steel plate that thickness is 10mm, has enough intensity, has improved practicality.Watertight rubber plate adopts the rubber tile that thickness is 20mm, and (L) type cross section is set in inner side, increases sealing area, and this set has strengthened access times and the stagnant water effect of watertight rubber plate.
