Abstract
The invention discloses a casing pipe defroster. The casing pipe defroster is designed by abandoning a casing pipe freeze protection method of injecting butter into a casing pipe and manufacturing the casing pipe into a through hole, breaking a traditional design philosophy of water plugging and water discharging, and adopting a brand new philosophy of deformation pressure relief. The casing pipe defroster comprises an anti-freezing block, wherein the anti-freezing block has the properties of being elastic and having no water absorption, when under pressure, the volume of the anti-freezing block shrinks, and the anti-freezing block absorbs the pressure, and when the pressure disappears, the volume of the anti-freezing block recovers to the original state, and furthermore when works under low outdoor temperature, the anti-freezing block still has the properties of being elastic and having no water absorption. The anti-freezing block firstly occupies a part of space inside the casing pipe after being placed at the bottom of the interior of the casing pipe, and volume expansion generated due to icing of water is counteracted through volume shrinkage deformation generated when the anti-freezing block is under the pressure, and accordingly the casing pipe is free of functions of frost heaving pressure, and furthermore when ice blocks thaw, volume deformation of the anti-freezing block can timely disappear, and the anti-freezing block still has a good freeze protection function even under the circumstance of repeated freezing and thawing.
Description
Technical field
The present invention relates to a kind of anti-icer, be specifically related to a kind of sleeve pipe anti-icer.
Background technique
It is a Frequently Asked Questions in engineering that bolt is installed with cover water inlet tube or water, and after water inlet, be difficult to water to clear up away from sleeve pipe, the water capacity when temperature reduces in sleeve pipe is easily frozen, and after freezing, volume will increase, in the space of a sealing, volumetric expansion power during water freezing will directly act on casing wall, if pressure is excessive, will cause the engineering diseases such as sleeve pipe bursting by freezing, at railway territory, due to the outdoor use of railway, the service sleeve of fastener is easy to into water and by bursting by freezing.
In order to solve the problem of cover water inlet tube frost heave, conventional means are functions that the method for employing sleeve pipe oiling realizes its water blockoff, in sleeve pipe, inject appropriate butter, during construction, injecting a certain amount of butter fills up the micro gap between bolt and sleeve pipe and occupies the space in sleeve pipe, entering and retaining of anti-sealing, realizes the effect of water blockoff, thereby prevents the frost heaving failure of sleeve pipe;
Also have a kind of processing method that sleeve pipe is made to through hole, sleeve body is Open architecture, once there be water to enter sleeve pipe, can immediately discharge, and its design concept is " draining ";
But all there is defect in existing antifreeze means:
(1) butter injection amount is difficult to guarantee, too much causes waste, cross the effect that does not have at least water blockoff, and butter cost is relatively high;
(2) butter belongs to organic substance, within the spreadable life of long period, is difficult to guarantee stability and the reliability of use;
(3) sleeve pipe is made to the way that through hole carrys out draining, sacrificed to a certain extent the structure of sleeve pipe, its stress performance will be greatly affected; And the structure that sleeve pipe is imbedded must be also through-hole structure, increase this structure area of stress concentration, easily recurring structure destroys.
(4) another shortcoming of sleeve pipe being made to through hole is sleeve bottom cavity, in the installation process of some structures, for avoiding concrete or other foreign material to enter, still needs through hole to take certain close measure.
Due to the existence of the problems referred to above, the inventor conducts in-depth research the antifreeze theory of existing sleeve pipe and method structure, to design simple to operately, reliability is high, the sleeve pipe anti-icer that cost is low.
