Abstract
The utility model relates to a connecting device of a plastic tubular product and inspection chamber. The utility model is mainly applied in the connection of the plastic tubular product and the inspection chamber and comprises a plastic short pipe 2 which is connected with the bell mouth 1-1 of the side wall of the inspection well 1 and an inspection well 1. The utility model is characterized in that: the bell mouth 1-1 of the side wall of the inspection well 1 is provided with a water swellable rubber sealing ring 3. A mediation layer 4 is arranged between the water swellable rubber sealing ring 3 and the bell mouth 1-1 of the side wall 1. Due to the arrangement, the utility model can prevent water leakage due to invalid sealing caused by temperature changes or geology sedimentation which replaces the pipe sheet.
Description
Technical field:
The utility model relates to a kind of connection set.Be specifically related to a kind of plastic tube and inspection shaft connection set.Be mainly used in being connected of plastic tube and inspection shaft.Metal conduit connection set technical field.
Background technique:
Traditional plastic tube and the Placement between the inspection shaft normally adopt tubing and inspection shaft to build altogether, tamp the leakproof effect that reaches with slush.Yet because there is very big difference in the expansion coefficient of plastics and cement, in the process of variation of ambient temperature or geology sedimentation, plastic tube produces displacement easily in the inspection shaft borehole wall, cause seal failure, and generation is oozed, water leakage phenomenon.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and the plastic tube and the inspection shaft connection set of favorable sealing property between a kind of plastic tube and inspection shaft is provided.
The purpose of this utility model realizes by following proposal: a kind of plastic tube and inspection shaft connection set, comprise plastic tubulature and inspection shaft, plastic tubulature is connected in inspection shaft borehole wall bellmouth, be characterized in being provided with the hydro-expansive rubber seal ring in the inspection shaft borehole wall bellmouth, be equipped with intermediary layer between hydro-expansive rubber seal ring and inspection shaft borehole wall bellmouth.
Compare with existing connection set, meet water self-expanding rubber seal owing to be provided with in the inspection shaft bellmouth of the present utility model, can avoid effectively because the plastic tube that variation of ambient temperature or geology sedimentation cause produces displacement in the inspection shaft borehole wall, cause seal failure, generation is oozed, water leakage phenomenon.
Description of drawings:
Fig. 1 is embodiment's 1 linkage structure schematic representation of the present utility model.
Fig. 2 is embodiment's 2 linkage structure schematic representation of the present utility model.
Embodiment:
As Fig. 1～2, the utility model is a kind of plastic tube and inspection shaft connection set.By inspection shaft 1, plastic tubulature 2 (generally adopt 0.5～0.8m), hydro-expansive rubber seal ring 3 and intermediary layer 4 form.Plastic tubulature 2 is connected in inspection shaft 1 borehole wall bellmouth 1-1, is characterized in the inspection shaft borehole wall bellmouth hydro-expansive rubber seal ring 3 being set, and is equipped with intermediary layer 4 between hydro-expansive rubber seal ring 3 and the inspection shaft borehole wall bellmouth 1-1.Intermediary layer 4 has two kinds of structural types, respectively referring to embodiment 1 and 2.
Embodiment 1:
As Fig. 1, intermediary layer 4 adopts the self-stressing concretes collar tie beam among Fig. 1, horn mouth or taper mouth 4-1 are made in self-stressing concretes collar tie beam 4 front portions, and step-like seam 4-2 is made at the rear portion, and hydro-expansive rubber seal ring 3 places in the step-like seam 4-2 at self-stressing concretes collar tie beam 4 rear portions.Hydro-expansive rubber seal ring 3 is enclosed within plastic tubulature 2 pipe ends earlier in plastic tubulature 2 is inserted to the seam 4-2 of the borehole wall bellmouth during installation, tamps with slush 5 in the horn mouth of self-stressing concretes collar tie beam 4 front portions or taper mouth 4-1 again.
Embodiment 2:
As Fig. 2, intermediary layer 4 adopts slush among Fig. 2.Hydro-expansive rubber seal ring 3 is enclosed within plastic tubulature 2 pipe ends earlier and is inserted to borehole wall bellmouth 1-1 with plastic tubulature 2 during installation, and tamp to reach the effect that is tightly connected with slush 4 in the space between plastic tubulature 2 and the bellmouth 1-1.
