The features of the present invention and other related features are described in further detail below by way of example in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:
as shown in fig. 1, the symbols 1-13 in the figure are respectively expressed as: the tunnel water-stop pipe comprises a tunnel pipe joint 1, a tunnel pipe joint 2, an existing OMEGA water-stop belt 3, an existing GINA rubber water-stop belt 4, an end steel shell 5, a UHPC bracket 6, a bracket end face steel structure 7, an inflatable air bag 8, an elastic filling body 9, a built-in OMEGA water-stop belt 10, a planting bar 11, a water-swelling water-stop glue 12 and a pre-embedded grouting pipe 13.
Example (b): the built-in combined waterproof connector with the elastic filling body in the embodiment is arranged at the position of the tunnel connector. As shown in fig. 1, the whole structure of the tunnel is formed by splicing a plurality of pipe sections, and the tunnel joint shown in fig. 1 is the connection position of the tunnel pipe section 1 and the tunnel pipe section 2. As shown in fig. 1, the tunnel pipe joint 1 and the tunnel pipe joint 2 are connected and fixed to form a whole, so as to ensure the stress and stability of the whole structure of the tunnel. A water stop structure formed by two waterproof combinations of an existing OMEGA water stop belt 3 and an existing GINA rubber water stop belt 4 is arranged at the joint position of the tunnel pipe joint 1 and the tunnel pipe joint 2, so that water seepage and water leakage at the joint position of the tunnel pipe joint 1 and the tunnel pipe joint 2 are avoided. Wherein, the existing GINA rubber waterstop 4 is positioned at the outer side of the existing OMEGA waterstop 3 along the longitudinal section direction of the tunnel, and two sides of the existing GINA rubber waterstop 4 are respectively provided with an end steel shell 5 for fixing.
As shown in fig. 1, the built-in combined waterproof joint with the elastic filling body in this embodiment includes UHPC brackets 6 respectively fixedly disposed on the tunnel pipe joint 1 and the tunnel pipe joint 2, and the two UHPC brackets 6 are respectively connected and fixed with the corresponding tunnel pipe joint 1 and the tunnel joint 2 through the embedded steel bars 11, so as to realize the function of bearing horizontal load of the UHPC brackets 6 and ensure the structural firmness thereof. The end surfaces of the two opposite sides of the UHPC brackets 6 are respectively provided with a bracket end surface steel structure 7, the shape and the size of the bracket end surface steel structure 7 are matched with those of the end surfaces of the opposite sides of the UHPC brackets 6, and the two are connected and fixed. The UHPC bracket 6 and the bracket end face steel structure 7 are used as a component main body of the waterproof joint, so that the thickness of the component is reduced, and the installation and construction are completed by utilizing the vacant boundary limits of the original building on the premise of not influencing the functions of the tunnel building.
As shown in fig. 1, a water-swelling waterproof adhesive 12 and a pre-embedded grouting pipe 13 are respectively arranged between the UHPC corbels 6 on the two sides and the corresponding tunnel pipe joints 1 or tunnel pipe joints 2, so as to realize water stopping at the connection part of the UHPC corbels 6 and the main body structures of the tunnel pipe joints 1 or tunnel pipe joints 2.
As shown in fig. 1, inflatable airbags 8 are respectively and fixedly arranged on the inner sides of the two corbel end face steel structures 7, and the filling ports of the inflatable airbags 8 can extend out of the corbel end face steel structures 7 to be arranged, so that technicians can conveniently inflate the inflatable airbags 8 or fill the elastic filling bodies 9 through the filling ports. As shown in fig. 1, an elastic filling body 9 is filled in the fillable air bag 9 on one side (i.e. the left side in fig. 1), and as the elastic filling body 9 is filled, the fillable air bag 8 gradually expands until it is tightly pressed against the fillable air bag 8 on the other side (i.e. the right side in fig. 1), thereby forming a waterproof function of the GINA-like water stop.
In some embodiments, as shown in fig. 1, the opposite side ends of the two bracket end face steel structures 7 are in a wedge-shaped seam-shaped structure, so that the squeezing effect of the GINA-like water stop band formed by the inflatable air bag 8 and the elastic filling body 9 under the action of water pressure is realized, and the waterproof water stop effect is further improved.
As shown in fig. 1, a built-in OMEGA water stop 10 is further disposed between the two corbel end face steel structures 7, and both ends of the built-in OMEGA water stop 10 are respectively fixedly connected to the two corbel end face steel structures 7. Along the longitudinal section direction of the tunnel pipe joint, the built-in OMEGA water stop 10 is positioned on the inner side of a GINA-like water stop formed by the inflatable air bag 8 and the elastic filling body 9 to form a second waterproof layer, so that the water stop effect is further ensured.
All components of the built-in combined waterproof connector with the elastic filling bodies in the embodiment are looped around the cross section of the tunnel pipe joint so as to realize complete water stop of the tunnel pipe joint.
The application method of the built-in combined waterproof joint with the elastic filling body in the embodiment refers to that the built-in combined waterproof joint is applied to water stopping repair of a tunnel joint after an existing water stopping structure fails, that is, as shown in fig. 1, when the existing OMEGA water stopping strips 3 and the existing GINA rubber water stopping strips 4 of the tunnel pipe joint 1 and the tunnel pipe joint 2 cannot realize a water stopping function, the tunnel pipe joint 1 and the tunnel pipe joint 2 need to be repaired with the water stopping function, and the built-in combined waterproof joint with the elastic filling body in the embodiment can be adopted.
Specifically, the built-in waterproof joint is installed at the joint position between the tunnel pipe joint 1 and the tunnel pipe joint 2 by the construction of the installation structure as described above. At this time, the similar GINA water stop composed of the inflatable air bag 8 and the elastic filling body 9 is used as a waterproof layer; meanwhile, the built-in OMEGA water stop 10 is used for two-way water prevention. Therefore, under the condition that the existing OMEGA water stop belt 3 and the existing GINA rubber water stop belt 4 are completely damaged, the two waterproof layers jointly realize the water stop function at the joint position of the tunnel pipe joint, and the water stop effect is ensured.
When the elastic filling body 9 in the inflatable air bag 8 at one side fails, the inflatable air bag 8 at the other side is inflated to serve as a temporary water stopping measure for repairing the built-in OMEGA water stop 10. That is, when the tunnel pipe joint 1 and the tunnel pipe joint 2 are subject to water seepage and water leakage after the built-in combined waterproof joint in the embodiment is installed for a period of time, it is described that both the elastic filling body 9 and the built-in OMEGA water stop strip 10 are failed, at this time, the inflatable air bag 8 on the other side is inflated to realize rapid temporary water stop, and then a technician can replace the built-in OMEGA water stop strip 10 under the condition that the temporary water stop takes effect, so that the water stop effect at the joint position of the tunnel pipe joint is ensured.
Although the conception and the embodiments of the present invention have been described in detail with reference to the drawings, those skilled in the art will recognize that various changes and modifications can be made therein without departing from the scope of the appended claims, and therefore, the description thereof is not repeated herein.
