Abstract

A waterproof device for a finished tie bar cable at the position of an embedded pipe orifice comprises a backing ring, a sealing sleeve, sealing filler, a screw, a pressing plate and a thermal shrinkable sleeve. The sealing sleeve is sleeved on the finished tie bar cable at the position of the embedded pipe orifice and fixedly connected with the embedded pipe orifice; the backing ring is placed in the sealing sleeve; the pressing plate is connected with the sealing sleeve through the screw; the sealing filler is filled in cavity formed by the sealing sleeve, the backing ring, the pressing plate and a finished tie bar cable body; and the thermal shrinkable sleeve is mounted outside the sealing sleeve, wraps the embedded pipe orifice and closely contacts with the cable body after being heated. The sealing filler filled between the sealing sleeve and the finished tie bar cable body is organic compound and epoxy resin or polyurethane and can also be inorganic compound and sealing putty, and the pressing plate is a circular ring pressing block with a taper inclined for 15-80 degrees from the center towards the external circle. The waterproof device has fine sealing and waterproof performances and is capable of effectively preventing water from entering an embedded pipe, thereby protecting the cable body and an anchor device and prolonging the service life of the tie bar inhaul cable.

Description

Tie-rod finished product rope is at the water-tight device at pre-buried mouth of pipe place
Technical field
The utility model relates to a kind of water-tight device, and particularly a kind of tie-rod finished product rope is at the water-tight device at pre-buried mouth of pipe place
Background technology
The tie-rod drag-line of finished product rope type need be provided with water-tight device at pre-buried mouth of pipe place after stretch-draw, anti-sealing enters in the pre-pipe laying, protection cable body and ground tackle; Water-tight device is in pre-buried mouth of pipe termination, and cable body passes in water-tight device; Existing water-tight device, block rubber 23, thermal shrinkable sleeve 24 by two semicircular ring are formed, referring to accompanying drawing 3, because there is the gap in the combination between the block rubber of two semicircular ring, simultaneously in the practice of construction installation process, have after the cable body distortion circle or cable body and the situation of pipe laying off-centre in advance, block rubber can not insert between pre-pipe laying and the cable body, and traditional block rubber does not play due waterproof action; The enlarging of pre-pipe laying makes the diameter of pre-pipe laying and cable body differ increasing in addition, and thermal shrinkable sleeve is easy to crack, and waterproof effect is poorer, and water enters in the pre-pipe laying, and ground tackle is corroded, and has influenced durability and application life that the tie-rod drag-line uses widely.
Summary of the invention
The purpose of this utility model is to provide the water-tight device of a kind of tie-rod finished product rope at pre-buried mouth of pipe place, and this device can prevent effectively that sealing enters in the pre-pipe laying, thereby protection cable body and ground tackle improve the durability that the tie-rod drag-line uses; To solve the bad problem of the existing existing waterproof effect of tie-rod finished product rope water-tight device.
The technical scheme that addresses the above problem is: a kind of tie-rod finished product rope is at the water-tight device at pre-buried mouth of pipe place, comprise gasket ring, sealing shroud, sealing filler, screw, pressing plate and thermal shrinkable sleeve, sealing shroud is enclosed within on the tie-rod finished product rope that is positioned at pre-buried mouth of pipe place, fixedlys connected with the pre-buried mouth of pipe; In sealing shroud, be placed with gasket ring, pressing plate is connected by screw with sealing shroud, be filled with the sealing filler in the cavity of sealing shroud, gasket ring and pressing plate and the formation of tie-rod finished product rustling sound body, thermal shrinkable sleeve closely contacts with finished product rustling sound body after being contained in the sealing shroud outside and encasing the pre-buried mouth of pipe, heating.
The described sealing filler that is filled between sealing shroud and the tie-rod finished product rustling sound body can be an organic compound: epoxy resin or polyamine fat; Also can be the greasy fat of inorganic compound-sealing
Its further technical scheme is: described pressing plate is an annular briquetting, and this annular briquetting has the therefrom tapering α of the outer circular direction inclination of mind-set, and the span of α is: spend less than 80 greater than 15 degree.
The water-tight device of tie-rod finished product rope at pre-buried mouth of pipe place of the utility model has following characteristics:
1, have good sealing property, good springiness, compliance are strong, and be even cable body flexural deformation also can seal, practical;
2, water-tight device design have in sealing shroud 4, gasket ring 3 and pressing plate 7 and cavity that cable body forms, be filled with first floor sealing that sealing filler 5 forms and be contained in sealing shroud 4 outsides and encase the pre-buried mouth of pipe 1, heating by thermal shrinkable sleeve 8 after closely contact with cable body and the second layer that forms seals double water-proof function, sealing filler in the water-tight device and thermal shrinkable sleeve all are elastomeric materials, can hold on cable body and can swing with cable body, improved the tie-rod water resistance, made the engineering construction of tie-rod drag-line more convenient simultaneously.
3, pressing plate 7 has cone angle, can smooth-going preferably transition thermal shrinkable sleeve 8, and rational in infrastructure, prevent that thermal shrinkable sleeve from ftractureing in advance because of the unreasonable unbalance stress of transition.
Therefore, the water-tight device of tie-rod finished product rope at pre-buried mouth of pipe place of the utility model has the excellent sealing water resistance, can prevent effectively that sealing enters in the pre-pipe laying, thereby protection cable body and ground tackle have improved durability and application life that the tie-rod drag-line uses; The tie-rod finished product rope water-tight device that has solved existing employing two halves formula block rubber preferably can't seal, leakage problem; Simultaneously, also solved can't assembling because of pre-pipe laying off-centre that the tie-rod finished product rope water-tight device of existing two halves formula block rubber exists, pre-pipe laying enlarging is difficult for construction problem such as makings grade; Have practicality and good economic benefit.
Be described further at the technical characterictic of the water-tight device at pre-buried mouth of pipe place below in conjunction with the tie-rod finished product rope of drawings and Examples the utility model.
