Problems solved by technology

[0004] Some research institutes or specialized testing companies may have conducted related experiments, but no institution or individual has proposed a complete and systematic set of methods specially used to simulate the quality of tunnel lining to obtain corresponding ground radar response characteristics. However, there are still great deficiencies in pertinence, comprehensiveness and reusability

Embodiment 1

[0047] The present invention will be further elaborated below through specific examples and accompanying drawings. It should be pointed out that what is disclosed below is only a preferred embodiment of the present invention, and certainly cannot limit the scope of rights of the present invention with this. Under the premise of departing from the principle of the present invention, those skilled in the art can also make some improvements and modifications, and these improvements and modifications should also be regarded as the protection scope of the present invention.

[0048] The simulation test device for the response characteristics of tunnel lining geological radar includes: a main body model 1 with a plurality of rectangular slots 10 penetrating the model reserved, rectangular concrete parts corresponding to the size of the slots 10 (including simulated steel bars, steel arches, cavities, cracked concrete columns, and concrete slabs to simulate voids), and the filling and...

Embodiment 2

[0073] here Figure 1 to Figure 15 The content is the same as that of Embodiment 1, only the type of concrete parts inserted in the slot is changed to simulate another lining quality situation.

[0074] Figure 17 It is the front view of the overall model of Example 2 of the present invention. Note that this is only one possible combination, and other combinations are possible. Here, the lining with poor quality is simulated, the upper reinforcement 2 is incomplete, pure concrete columns are inserted into the 5th slot, and reinforced concrete columns are inserted into the other 5 slots; there is a hollow in the middle, and a hollow concrete slab is inserted into the rectangular slot ;The lower part of the steel arch frame is complete, the steel arch concrete columns are inserted into the 1st, 3rd, and 5th slots, and the pure concrete columns are inserted into the 2nd and 4th slots; there is no cavity in the middle, and all square slots are inserted Pure concrete columns.

Abstract

The invention provides a simulation test device for a response characteristic of a tunnel lining geological radar and a test method thereof. The simulation test device comprises a main body model made from concrete, wherein a plurality of clamping slots are formed in the main body model; concrete simulation components which are matched with the clamping slots and are used for simulating different lining structure types or different geological defects are arranged in the clamping slots; the concrete simulation components and the main body model are combined to form an integrated model; the geological radar is used for detecting the position above the integrated model to obtain the response characteristics of different lining structures in the geological radar. The simulation test device can be used for simulating the structures of tunnel lining concrete, reinforcement fabrics and steel arches and defects that the untightness of the lining is not matched with disengagement, cracks, caves, ponding and steel bar distribution and the like and can comprehensively simulate various situations in detection of the actual lining quality. The simulation test device can simulate various different situations only by changing the types of the concrete simulation components inserted into the clamping slots and is extremely high in reusability.

Description

technical field [0001] The invention relates to a test device for detecting the quality of tunnel lining, in particular to a test device and method for detecting the response characteristics of tunnel lining in geological radar. Background technique [0002] With the development of my country's economy, tunnels have been greatly developed as an important way to relieve traffic pressure across complex terrain. However, there are many unforeseen factors in tunnel construction, which are likely to cause quality problems such as lack of compactness and voids in the tunnel lining, internal cracks in the lining, water accumulation in cavities and loose areas of backfill, and reinforcement distribution that does not conform to the design. In order to ensure the quality of the lining and ensure the safety of the tunnel, the quality inspection of the tunnel lining is very important. The main part of the tunnel is a hidden project, and it is difficult to inspect the quality of the pr...
