Abstract
The invention relates to an intermediate jacking station mud and sand prevention device which comprises two intermediate jacking station fixing sealing rings. Four grease oils are formed between the two intermediate jacking station fixing sealing rings and are connected with a grease pump. The four grease oils are distributed along the circumference of an intermediate jacking station. After the intermediate jacking station mud and sand prevention device is adopted, mud can be effectively prevented from entering the intermediate jacking station, the technical problem of friction losses of water stop sealing rubber rings is solved, and using safety of the intermediate jacking station is ensured.
Description
Technical field
The present invention relates to a kind of pipe jacking equipment of construction, especially a kind of for the anti-device for silt of layer of sand driving relay well.
Background technique
In sandy soil layer, relay well is carried out dynamic analog test, find after the relay well of seepage is removed, the relay well bottom has sand to enter seal ring, causes the relay well seepage.
By analysis, relay well is to rely on that between the male and female head, sealing rubber ring comes sealing, and push pipe is in sandy soil layer during jacking, quicksand can constantly enter between relay well activity male and female gaps, that is to say, quicksand directly and seal ring produce and rub, sand grains is very easily drawn and is split and the abrasion watertight rubber.
Summary of the invention
The present invention will provide a kind of relay well to prevent device for silt, is used for solving the technical problem that the abrasion of waterstop sealing rubber ring causes the relay well seepage.
For achieving the above object, technological scheme of the present invention is: a kind of relay well is prevented device for silt, comprises relay well twice fixed seal ring, is characterized in: four grease holes are set between relay well twice fixed seal ring, and four grease holes are connected with grease pump.
Four grease holes are along the relay well circumference uniform distribution.
The invention has the beneficial effects as follows: after adopting this device, can prevent effectively that mud from entering relay well, solve the technical problem of waterstop sealing rubber ring abrasion, guarantee the use safety of relay well.
Description of drawings
Fig. 1 is structure sectional view of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1, relay well of the present invention is prevented device for silt, comprises relay well twice fixed seal ring 1.Four grease holes 2 are set between relay well twice fixed seal ring 1, and four grease holes 2 are connected with grease pump.Four grease holes 2 are along the relay well circumference uniform distribution.
The present invention adopts and concentrates automatic discontinuous formula for the fat formula.Have discontinuously the grease of certain pressure with pump to pressure injection between relay well twice fixed seal ring 2 through distributing valve, can regulate delivery volume by timer and pressure.The pattern of this device employing time and pressure co-controlling is under normal conditions by the time lag greasing that sets.If but the pressure of sealing place is during less than the low pressure limit that sets, pressure is controlled preferential, and the beginning greasing is until the upper pressure limit that sets.
Claims (2)
1. the anti-device for silt of relay well, comprise relay well twice fixed seal ring (1), it is characterized in that: four grease holes (2) are set between described relay well twice fixed seal ring (1)), and four grease holes (2) are connected with grease pump.
2. the anti-device for silt of relay well according to claim 1, is characterized in that; Described four grease holes (2) are along the relay well circumference uniform distribution.
