Abstract
Disclosed is an inflation changeable seal element relaying chamber, which is characterized in that a seal element cover plate is arranged on the back end of the relaying chamber oil cylinder, the cover plate is fixed by a bolt. The seal part is made of two identical seal elements, an inflation tube and an inner milling ring, the seal element withstands the inner milling ring, the seal element and the inflation tube are inflated and integrated to be one system.
Description
Technical field: the utility model relates to the pipe-jacking technology field, belongs to a kind of relay well equipment of long-distance pipe jacking work progress specifically.
Background technique: the relay well in the pipe-jacking technology is because of the damage of rubber seal or because other reasons generation poor sealing is a common phenomenon, main Sealing will be subjected to the restriction of elasticity and wear resistance, the wear resistance of rubber is good, poor flexibility, otherwise good springiness, the wearing no resistance of rubber, the push pipe relay well of distance in use have up to ten thousand time back and forth, can produce seepage, in a single day the relay well Sealing produces the seepage phenomenon, can be exactly a kind of catastrophic defect for the construction of pipe-jacking technology.At first, underground water and silt particle leak into to come in the pipe from Sealing can influence construction operation.Secondly, a large amount of silt particles and underground water loss can make surface subsidence increase, and serious meeting causes above ground structure or underground utility and structure to damage.Once more, can accelerate the wearing and tearing of Sealing after the silt particle infiltration, produce vicious circle.At last, owing to the seepage of relay well has been destroyed the anti-attrition slurry cover that is wrapped in the pipe outside, make the thrust surge, even may cause the jacking construction failure.
For this reason, Sealing in the past also has the form made from the manual tune decrement, i.e. decrement of regulating Sealing with the many screws that are located at a week in the relay well.This regulative mode has two shortcomings, and the one, the part of being regulated is spot distribution, and the place that is not adjusted to still can produce seepage.The 2nd, the relay well housing can produce distortion in jack-in process, adopt above-mentioned regulating method can't in time recognize its distortion situation, thereby extremely inconvenient.
Summary of the invention; The relay well sealed member that the purpose of this utility model provides the long distance construction process can not produce seepage, to the replaceable Sealing relay well of a kind of gas-filled type of Sealing easy accessibility.
For finishing the technological scheme that above-mentioned purpose is taked: by forward and backward housing, relay well oil cylinder, the utility model that Sealing and clamp are formed, it is characterized in that relay well oil cylinder rear end is provided with the Sealing cover plate, cover plate is by bolt, hermetic unit is made up of the identical Sealing of two covers, gas tube and interior bull ring, Sealing withstands interior bull ring, and above-mentioned Sealing and gas tube sufficient gas are for fusing.
The utlity model has firm sealing, overcome the form of the manual tune decrement of prior art, the seepage that solution relay well housing can produce in jack-in process guarantees the safety of relay well in work progress and effective.
Description of drawings:
Fig. 1 is the utility model structural drawing;
Fig. 2 is the utility model hermetic unit structural drawing.
According to illustrated in figures 1 and 2, front case 1 and rear case 8, relay well oil cylinder 2, Sealing 6 four major parts and clamp 3 are formed the utility model, relay well oil cylinder 2 rear ends are provided with Sealing cover plate 5, cover plate 5 is fixing by bolt 4, hermetic unit is made up of the identical Sealing 6 of two covers, gas tube 7 and interior bull ring 9, Sealing 6 withstands interior bull ring 9, and above-mentioned Sealing 6 and gas tube 7 sufficient gas are for fusing.Shown in jacking direction shown in Figure 1, a cover Sealing is a Sealing commonly used on the right, and the right one cover is a back-up seal.In the work, Sealing sufficient gas commonly used, wear ring is close to front case, constitutes sealing together with it, can normally use.If Sealing commonly used damages, then can allow the back-up seal sufficient gas it play seal action.Then, relay well oil cylinder retraction, reserve enough spaces.Then can twist hexagon socket head cap screw and go, the Sealing cover plate toward moving to left.So just can take out Sealing commonly used and be changed.Refill after finishing changing, continue to use by normal mode.
Because Sealing is made up of wear ring and air bag two-part, so the rubber that it is good that wear ring can adopt wear resistance is made, the then available elasticity of air bag rubber is preferably made.Owing to be filled with pressurized air in the air bag, so be worn or after the relay well housing was out of shape, Sealing can compensate above-mentioned two kinds of gaps automatically, uses under safe and reliable condition to guarantee relay well at Sealing.
Claims (2)
