Apply to city to have stable political situation the fields such as the buried draining of building, combustion gas, blowdown and heat supply heating.
But in municipal drainage, drainage project, because tubing needs to carry out buried treatment, the ring stiffness, ring to tubing are soft
Degree proposes requirement higher.And the production consumption raw material of common polyethylene buried pipeline, particularly large diameter pipeline is more, right
Equipment requirement is high, and ring stiffness is generally relatively low.Can not expire completely for the requirement such as municipal main pipeline construction costs, buried
Foot, therefore, come into operation we have proposed a kind of enhanced helical bellows of internal-rib, to solve the above problems.
Utility model content
The purpose of this utility model is to provide a kind of enhanced helical bellows of internal-rib, with solving above-mentioned background technology
The existing helical bellows ring stiffness and the relatively low problem of ring flexibility for proposing.
To achieve the above object, the utility model provides following technical scheme：A kind of enhanced helical bellows of internal-rib, bag
Body is included, the tube surfaces are evenly arranged with the crest of hot melt molding, and the crest includes PE outer layers and PE internal layers, the PE
Waveform steel band is coated between outer layer and PE internal layers, spiral trough is provided between crest described in two groups, the crest inner chamber is vertical
Internal-rib reinforcing plate is provided with, and internal-rib reinforcing plate bottom is compounded in body top, the top of the internal-rib reinforcing plate by binder
It is connected with the top of crest by bolster, the left and right sides of the internal-rib reinforcing plate is arranged with assistant reinforcement plate, and two groups
The other end of assistant reinforcement plate is connected with the side wall of crest.
Preferably, the crest is uniformly arranged on tube surfaces, the crest and helicon at equal intervals with spiral trough
Between 0.18-1.4 millimeters, the distance between crest described in two adjacent groups is 1.8 millimeters to the distance between paddy.
Preferably, the arc fagging being adapted with crest, the bottom of the arc fagging are provided with the top of the bolster
Return springs are connected with, and return springs are located at the inner chamber of bolster.
Compared with prior art, the beneficial effects of the utility model are：The enhanced helical bellows of the internal-rib, with high-strength
The features such as degree, high rigidity and epipodium flexibility, the use of polyethylene raw material can be reduced by the hollow crest in hot melt molding inner chamber,
Compare same diameter, can significantly reduce cost with the all-plastic underground pipe of ring stiffness, while compared with traditional drainpipe, with close
The features such as envelope reliability, long service life, lightweight, convenient and quick construction, have a wide range of applications field.
