Abstract
The invention discloses a sealed box culvert, which is a hollow box body structure with two opened ends and comprises two ports, and at least two sealing structures are respectively arranged at the joints of the two ports. By adopting multi-layer sealing structures, the sealing effect of the joints of the box culvert is remarkably improved, as a result, the service life of the box culvert is prolonged; and in addition, preformed holes are formed in the joints of the ports of the box culvert and can be used for measuring the pressure of the joints, and cement slurry can be filled via the preformed holes after the box culver is used for a long term and sealing rings perish, so that the service life of the box culvert is further prolonged.
Description
[technical field]
The present invention relates to a kind of box culvert, particularly relate to a kind of sealing box culvert.
[background technology]
The walkway of city box-type section and electric power, the reasonable mode of cable passage are to adopt to lay prefabricated box culvert now, duration can be saved like this, guarantee easily workmanship, reduce the labour, simultaneously to urban traffic and the citizen unlikely too much influence that causes of living.
Because it is underground that box culvert generally is embedded in, if seal badly, underground water is easy to infilter box culvert, destroys the environment in the box culvert passage, and especially electric power box culvert waterproof seems extremely important.
Existing box culvert generally is in the tongue and groove junction of box culvert a sealing ring to be installed, but box culvert is concrete structure, and its surface itself is just more coarse, and construction environment is poor, and silt is easy to be clipped between sealing ring and the box culvert, is easy to make seal failure.This single sealing ring sealing effectiveness is bad, the reliability deficiency.And sealing ring is plastic material, and the life-span of plastic material is shorter, rots easily to lose efficacy.
[summary of the invention]
Bad for overcoming the prior art sealing effectiveness, technical problems such as reliability deficiency the invention provides the preferable sealing box culvert of a kind of sealing effectiveness.
The technical scheme that the present invention solves the prior art problem is: a kind of sealing box culvert is provided, and it is the hollow box body structure of both ends open, and the sealing box culvert comprises two ports, and the junction of this two port is respectively provided to few two seal structures.
Preferably, this two port has first projection, second projection respectively, and first projection is corresponding with second projection, and the close box culvert inboard of first projection, and second projection is near the box culvert outside, and first projection arranges a preformed hole, and preformed hole runs through first projection.
Preferably, this preformed hole is arranged between two seal structures at least.
Preferably, the sealing box culvert comprises at least two sealing rings, the sealing ring cross sectional shape is circular, wedge shape or polygon, and the lateral surface of sealing box culvert first projection has at least two grooves that arrange at interval, and this at least two sealing ring is placed in respectively in this two groove at least.
Preferably, the sealing box culvert comprises at least two sealing rings, lateral surface setting at least two steps of first projection, the medial surface of second projection also has at least two steps corresponding with first projection, and this at least two sealing ring is positioned the endface position of at least two steps of this first protruding lateral surface respectively.
Preferably, this at least two seal structures is a bull sealing ring, and the shape of cross section of this bull sealing ring is zigzag, and its sawtooth contacts with the second protruding medial surface of the sealing box culvert that is connected.
Preferably, this at least two seal structures is a double end sealing ring, and it comprises two zigzag projectioies, this two zigzags bulge clearance certain distance, and its top arranges a round end respectively.
Preferably, the sealing box culvert comprises at least two sealing rings, and the sealing circle has a base and a head, and the base of sealing circle is implanted in first projection of sealing box culvert, and its head contacts with the second protruding medial surface of the sealing box culvert that is connected.
Preferably, this at least two seal structures keeps at a certain distance away in the horizontal direction, and it is poor to have certain altitude in the vertical direction.
Sealing box culvert of the present invention obviously strengthens the sealing effectiveness of box culvert junction by multi-layer sealed leakage preventing structure is provided, thereby has prolonged the application life of box culvert.In addition, by in box culvert port junction one preformed hole being set, can measure the pressure of junction by preformed hole, and box culvert through long-term use sealing ring to rot after, can also be from the preformed hole grout injection, thus further prolong application life of box culvert.
