Abstract
Disclosed is a duct piece infiltration detector for shields. A support is arranged below an arc plate which is provided with a water inlet hole. The water inlet hole is connected with a water pump, and a duct piece to be detected is disposed above the arc plate. A sealing frame is arranged between the arc plate and the duct piece to be detected and made of rubber. The water pump is provided with a pressure gauge. Infiltration of the duct piece can be detected by the duct piece infiltration detector, and quality thereof can be evaluated reasonably. The problem that infiltration of the duct piece during shield construction is not easy to be measured is effectively solved. In addition, the duct piece infiltration detector for shields is simple in structure, convenient to operate and easy to be popularized in shield construction.
Description
Technical field
The utility model relates to the shield-tunneling construction field, relates in particular to a kind of shield duct piece infiltration detector.
Background technology
Continuous development along with China's subway, large-scale seepage tunnel; Shield-tunneling construction has become a kind of trend, the safety of the relationship between quality shield-tunneling construction of section of jurisdiction wherein, and the section of jurisdiction perviousness detects and does not have reference instrument at present; Can't accurately check the perviousness of section of jurisdiction, easily construction caused adverse effect.
Summary of the invention
The utility model technical matters to be solved provides a kind of shield duct piece infiltration detector, and is simple in structure, easy to use.
In order to solve the problems of the technologies described above, the technical scheme of the utility model is: a kind of shield duct piece infiltration detector, and the arc below is provided with bracing frame, and arc is provided with the inlet opening, and the place, inlet opening connects water pump, and section of jurisdiction to be measured places the top of arc.
Also be provided with the sealing frame between arc and the section of jurisdiction to be measured.
Said sealing frame is selected the rubber material for use.
Said water pump is provided with tensimeter.
A kind of shield duct piece that the utility model provides permeates detector, can detect the perviousness of shield duct piece, and its quality is carried out reasonable assessment, and is workable, effectively guarantees carrying out smoothly of construction.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, arc 1 below of the utility model is provided with bracing frame 2, and arc is provided with inlet opening 3, and 3 places, inlet opening connect water pump 4, and section of jurisdiction 5 to be measured places the top of arc 1.
Also be provided with sealing frame 6 between arc 1 and the section of jurisdiction to be measured 5.
Said sealing frame 6 is selected the rubber material for use.
Said water pump 4 is provided with tensimeter 7.
When using the utility model, curved plate 1, sealing frame 6 and section of jurisdiction to be measured 5 are surrounded an obturator, use water pump 4 in inlet opening 3, to inject the water of certain pressure, continue a period of time, sighting tube lamella water the infiltration situation, the perviousness of judgement section of jurisdiction.
