Abstract
The invention relates to the shield tunnel construction technologies, particularly to a plugging device for a large-aperture hand hole in a shield tunnel. The plugging device comprises a jacking enveloping box composed of a closed enveloping frame and a jacking plate located therein, the jacking plate and an inner wall of the enveloping frame are clearance fit, and an external side of the jacking plate is provided with a jacking handle. The plugging device for the large-aperture hand hole in the shield tunnel has the following advantages: the structure is simple and rational, by jacking of the jacking plate in the enveloping frame, plugging materials in a cavity of the enveloping frame can be jacked and pushed into the hand hole at once so as to effectively plug the hand hole, so that once plugging molding of the hand hole is implemented, compactness of plugging the hand hole of the tunnel is ensured, and demands on corrosion prevention and durability of bolts are satisfied.
Description
Technical field
The present invention relates to the shield tunnel construction technology class, particularly a kind of plugging device that is used for shield tunnel large pore hand hole.
Background technology
Shield tunnel is used widely in buried underground construction.The life requirement in tunnel comprises many aspects, and wherein the bolt anti-corrosion measure is the important component part of life requirement, so need carry out shutoff for the large aperture hand hole, and to satisfy the anti-corrosive durability requirement of bolt.At present, shield tunnel is by building operation platform, adopt instruments such as common putty knife, spatula, putty knife, carrying out shutoff for the hand hole in the tunnel in the work progress of hand hole blocking.Under the bigger situation of hand hole bore, because above-mentioned instrument normally is used for building, using when fitting up at common building, its size dimension differs, but the chamber that neither one is fixing, can only utilize one face to be loaded with filler, repeatedly a hole be filled then, especially for the hand hole of tunnel top, because its position is higher, very inconvenience during construction.And under the situation of repeatedly filling, can't guarantee that the material that the constructor fills reaches enough closely knit requirement.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, a kind of plugging device that is used for shield tunnel large pore hand hole is provided, this device has the jacking outsourcing box of cavity by setting, and jacking plate that can pushing tow moves in jacking outsourcing box, remedies the deficiency of conventional art.
The object of the invention realizes being finished by following technical scheme:
A kind of plugging device that is used for shield tunnel large pore hand hole, it is characterized in that described plugging device comprises jacking outsourcing box, by the outsourcing frame that is closed and place the jacking plate of its inner end to constitute, profile forms matched in clearance in described jacking plate outline and the described outsourcing frame, described jacking plate can vertically move along outsourcing frame inwall, and described jacking plate arranged outside has a jacking handle.
The volume of the inner chamber of described jacking outsourcing box is not less than the volume of described large aperture hand hole.
Gap 2mm between the profile in described jacking plate outline and the described outsourcing frame.
Advantage of the present invention is: simple and reasonable, bigger by the ratio hand hole that the cavity with jacking outsourcing box is provided with, a pushing tow can effectively be finished the shutoff of a hand hole, not only realized a shutoff moulding of hand hole, and guarantee the density of tunnel hand hole blocking to satisfy the anti-corrosive durability requirement of bolt.
Description of drawings
Accompanying drawing 1 is user mode schematic diagram of the present invention;
Accompanying drawing 2 is apparatus of the present invention structural representation.
The specific embodiment
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Shown in Fig. 1-2, mark 1-6 is not among the figure: hand hole 1, packing material 2, jacking outsourcing box 3, jacking plate 4, jacking handle 5, outsourcing frame 6.
Referring to Fig. 1-2, plugging device comprises jacking outsourcing box 3 in the present embodiment, and outsourcing box 3 is made up of outsourcing frame 6, jacking plate 4 and jacking handle 5.
Wherein, outsourcing frame 6 is that front and back connect the sealing frame that is hollow.
Shape and size match each other between the in-profile of the appearance profile of jacking plate 4 and outsourcing frame 6.When work, jacking plate 4 places outsourcing frame 6 inner chambers one end, and the gabarit of jacking plate 4 becomes matched in clearance with the interior profile of outsourcing frame 6.Specifically, jacking plate 4 forms matched in clearance between its side profile and jacking outsourcing frame 6 inner surface contours, but it can be slided in outsourcing frame 6 in being positioned over outsourcing frame 6 in the above described manner the time.Realize this slip for ease of operation jacking plate 4, vertical fixing has a jacking handle 5 in one side center.
In construction, packing material 2 adopts aluminium sulfate to surpass early strong (microdilatancy) cement, and can be according to self filling operating time, and the aluminium sulfate that proposes to prolong time of setting to manufacturer surpasses early strong (microdilatancy) cement type requirement.For above-mentioned packing material 2, based on its viscosity, gap 2mm between the profile in jacking plate 4 outlines and the outsourcing frame 6, to realize above-mentioned matched in clearance, and in such cases, the gap is 2mm to the maximum between jacking plate 4 and the side plate 6, can not cause overflowing of packing material 2, and has guaranteed being slidingly matched between jacking plate 4 and the outsourcing frame 6.
Be 1 shutoff moulding of realization hand hole, and will guarantee the density of tunnel hand hole 1 shutoff, so the volume of the inner chamber of jacking outsourcing box 3 is not less than the volume of large aperture hand hole 1.Specifically, when jacking plate 4 is positioned at a termination of outsourcing frame 6, constitute jacking outsourcing box 3 volume should be not less than the volume of wide-aperture hand hole 1, openend with jacking outsourcing box 3 is relative with the opening port mouth of hand hole 1 afterwards, after advancing jacking plate 4, could guarantee a shutoff moulding.
Claims (3)
1. plugging device that is used for shield tunnel large pore hand hole, it is characterized in that described plugging device comprises jacking outsourcing box, by the outsourcing frame that is closed and place the jacking plate of its inner end to constitute, profile forms matched in clearance in described jacking plate outline and the described outsourcing frame, described jacking plate can vertically move along outsourcing frame inwall, and described jacking plate arranged outside has a jacking handle.
2. a kind of plugging device that is used for shield tunnel large pore hand hole according to claim 1 is characterized in that: the volume of the inner chamber of described jacking outsourcing box is not less than the volume of described large aperture hand hole.
3. a kind of plugging device that is used for shield tunnel large pore hand hole according to claim 1 is characterized in that: gap 2mm between the profile in described jacking plate outline and the described outsourcing frame.
