Abstract
The invention provides an immersed tunnel model test device for simulating a hydraulic compression joint mode through rubber airbags, and belongs to the technical field of tunnel engineering. The immersed tunnel model test device comprises a model casing, rigid plates, the rubber airbags, a water covering layer, a lower gravel layer, an upper gravel layer, an immersed tunnel model, valves and inflation guide pipes. The lower gravel layer is laid in the model casing, and the immersed tunnel model is arranged on the lower gravel layer. The rubber airbags are arranged at the two ends of the immersed tunnel model and fixed to the inner walls of the model casing through the rigid plates. The rubber airbags are connected with the inflation guide pipes, and controlled through the valves. The upper gravel layer is laid on the immersed tunnel model, and the water covering layer is used for simulating a real water environment. The immersed tunnel model test device has the advantages that the immersed tunnel model is always in a stressed state in the test process and is in elastic contact with the model casing rather than fixed connection or rigid contact. The immersed tunnel model can well simulate the hydraulic compression joint mode between two pipe sections of a real immersed tunnel in the test process.
Description
Technical field
The invention belongs to Tunnel Engineering technical field, relate to immersed tube tunnel model test, be related specifically to the immersed tube tunnel model test apparatus adopting rubber pneumatic bag Simulated Water to defeat the mode of connecing.
Background technology
Immersed tube tunnel model test apparatus is the universal means of carrying out immersed tube tunnel correlation test.Existing immersed tube tunnel model test apparatus, at the two ends of immersed tube tunnel model, with model casing touching position, all adopts the rigid contact being fixedly connected with or not applying any connected mode.And in the immersed tube tunnel of reality, between two pipeline sections, there is GINA rubber washer, rely on waterpower crimping, its essence is Elastic Contact.Therefore in existing immersed tube tunnel model test apparatus, in the way of contact processing immersed tube tunnel model and model casing, have very big difference with actual.
Summary of the invention
The technical problem to be solved in the present invention is the waterpower crimping mode that in immersed tube tunnel model test, real simulation Joints in Immersed Tunnel connects.
Technical scheme of the present invention:
Adopt rubber pneumatic bag Simulated Water to defeat an immersed tube tunnel model test apparatus for the mode of connecing, comprise model casing, rigid plate, rubber pneumatic bag, cover water layer, lower floor's sand stone layer, upper strata sand stone layer, immersed tube tunnel model, valve and inflating catheter;
In model casing, be covered with lower floor's sand stone layer, it arranges immersed tube tunnel model; Immersed tube tunnel model two ends arrange rubber pneumatic bag, defeat the way of contact connect for Simulated Water; Rubber pneumatic bag is fixed on model casing inwall by rigid plate; Rubber pneumatic bag is connected with inflating catheter, passes through Valve controlling; Immersed tube tunnel model is laid upper strata sand stone layer, upper strata sand stone layer is laid with and covers water layer, cover water layer for Reality simulation water environment.
Effect of the present invention and benefit are that immersed tube tunnel model is in pressured state all the time in process of the test, and the way of contact of itself and model casing is Elastic Contact, but not is fixedly connected with or rigid contact.The waterpower that immersed tube tunnel model be can be good between Reality simulation immersed tube tunnel two pipeline section in process of the test crimps mode.
