Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
It is noted that following detailed description is all exemplary, be intended to provide further instruction to the application.Unless otherwise, all technology used herein and scientific terminology have the identical meanings usually understood with the application person of an ordinary skill in the technical field.
In the utility model, when not doing contrary explanation, the noun of locality of use if " upper and lower, top, the end " is normally for direction shown in the drawings, or for vertically, on vertical or gravity direction; Similarly, for ease of understanding and describing, " inside and outside " refers to profile inside and outside relative to each parts itself, but the above-mentioned noun of locality is not limited to the utility model.
Not good in order to solve electric power tunnel structurally waterproof performance of the prior art, and easily with the problem of the easy adhesion of periphery framework also together sedimentation, the utility model provides a kind of tunnel structure.Here tunnel structure is applied in electric power tunnel especially.
As shown in Figure 1, tunnel structure comprises main body 10 and for fire-retardant protection portion 30; Main body 10 has the tunnel structure chamber 40 that the length direction along main body 10 extends, on the inner surface that protection portion 30 covers main body 10 and/or external surface.
Because main body 10 has the tunnel structure chamber 40 extended along its length, thus ensure that cable has space of extending fully in tunnel structure, be not easily squeezed or collide with thus cause cable bad.On the inner surface covering main body 10 due to protection portion 30 and/or external surface; thus tunnel structure chamber 40 and the external world are isolated effectively; avoid extraneous water permeation inner to tunnel structure chamber 40; ensure that the dependability of tunnel structure; and the main body 10 of tunnel structure is not directly contacted with periphery framework; thus prevent tunnel structure and the adhesion of periphery framework from sinking, improve the stability that tunnel structure uses.
Alternatively, protection portion 30 is that polyethylene foams is made.Protection portion 30 is made to have good extension property and tensile strength like this; various ground lower surface camber and labyrinth can be adapted to; the intensity of protection portion 30 can also be improved; make its can not local broken and come off; moreover, make protection portion 30 have excellent fireproof performance and fire resistance, running into fire can self-extinguish; thus ensure that the safety of cable work, and the feature of environmental protection of protection portion 30 is good, construction is clean and tidy efficiently, perception is better, meet environmental requirement.
Alternatively, any one in the cross section semicircular in shape of the length direction perpendicular to main body 10, ellipse, rectangle or triangle of tunnel structure chamber 40.
As shown in Figure 1, in a kind of embodiment of the present utility model, tunnel structure also comprises overcoat 20, and overcoat 20 covers on the surface of protection portion 30, is folded between main body 10 and overcoat 20 to make protection portion 30.Like this, overcoat 20 extends the time that protection portion 30 is made moist or corroded, and improves the protective value of protection portion 30 pairs of tunnel structures.
Alternatively, overcoat 20 is any one in sponge, rubber pad, magazine or glass fiber reinforced plastic.
Alternatively, protection portion 30 comprises multiple guard members 31 that the length direction along main body 10 arranges in turn, and the intersection of adjacent two guard members 31 is stacked.Like this, multiple guard member 31 can be dismantled respectively, can carry out Replacement and Repair one by one to the guard member 31 of breakage, improves the convenience that protection portion 30 uses.
Can imagine; the length direction of the main body 10 of the tunnel structure in Fig. 1 along tunnel structure chamber 40 is constantly extended; and the length direction of guard member 31 along tunnel structure chamber 40 is arranged in turn, protection portion 30 entirety formed to make guard member 31 covers on the external surface of main body 10.
Alternatively, adjacent two guard members 31 by bonding, riveted joint or welding in a kind of mode connect.
As shown in Figure 3, guard member 31 has the first protection section 311 covered on the first external surface 11 and the second protection section 312 covered on the second external surface 12.Like this; because guard member 31 is provided with the first protection section 311 covered on the first external surface 11 and the second protection section 312 covered on the second external surface 12; first protection section 311 and the second protection section 312 have the structure matched with the structure of main body 10; thus can for a full due main body covered 10 external surface, improve the practicality of protection portion 30.
Alternatively, protection portion 30 has independent two-way chemical cross-linked structure.Like this, enhance the ability that protection portion 30 adapts to complicated underground environment, and make protection portion 30 under the cooperation of bonding adhesive can with coiled material secure bond, formed closed protective.
As depicted in figs. 1 and 2; main body 10 is in arch; the external surface of the main body 10 in arch comprises the first external surface 11 and to be connected with the both sides of the first external surface 11 and respectively to downward-extension and the second external surface 12 be oppositely arranged, protection portion 30 covers on the external surface of main body 10.Because main body 10 is in arch, thus tunnel structure is had minimum construct stressed effect, add the service time of tunnel structure.Because protection portion 30 covers on the external surface of main body 10; thus make protection portion 30 can directly go deep into tunnel main body 10 by anti-sealing; can be formed simultaneously and the waterproofing course of tunnel structure is protected for a long time and isolated, improve the stability of tunnel structure chamber 40 inside cable work.
As shown in Figure 2, the first external surface 11 is plane or cambered surface, and when the first external surface 11 is plane, the first external surface 11 is in horizontal plane.Like this, protection portion 30 and overcoat 20 can be facilitated to lay conveniently at the inner surface of main body 10 and/or external surface, make protection portion 30 and overcoat 20 directly lay bottom to main body 10 from the top of main body 10.
