Abstract
The utility model relates to a simple device for controlling a grouting reinforcement pressure of an existing subgrade to effectively detect and control a grouting reinforcement pressure. The simple device comprises detection pipes (3) longitudinally arranged below an embankment subgrade bed surface layer (2) at intervals along a road, wherein detachable geotechnical cloth plugs (4) are arranged at two ports of the detection pipes (3); and through holes (3a) are longitudinally formed at intervals at the lower parts of the detection pipes (3) along a pipe body.
Description
Technical field
The utility model relates to railway, highway subgrade, particularly a kind of existing roadbed grouting and reinforcing pressure control easy device.
Background technology
Railway, subgrade settlement is modal a kind of in the subgrade defects such as highway, adopting grouting and reinforcing is present the most frequently used method, but grouting and reinforcing sinking roadbed requires to satisfy to pollute top structure such as railroad ballast usually, can not cause roadbed arch impact to use such as the non-fragment orbit Line for Passenger Transportation, this brings a difficult problem for the design of sinking roadbed grouting and reinforcing and construction, because because filling roadbed material difference and the compactness uncertainty of first-class factor not, want by theoretical calculative determination grouting pressure and slip casting radius very difficult, if insufficient pressure then can not reach grouting consolidation effect, pressure is crossed conference and is caused the roadbed arch and pollute superstructure, is badly in need of a kind of effective existing roadbed grouting and reinforcing pressure control device for this reason.
The utility model content
Technical problem to be solved in the utility model provides a kind of existing roadbed grouting and reinforcing pressure control easy device, effectively to detect and to control grouting and reinforcing pressure.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
Existing roadbed grouting and reinforcing pressure control easy device of the present utility model, it is characterized in that: it comprises along circuit longitudinal separation and is arranged at detector tube under the embankment surface layer of subgrade bed, the two-port of detector tube is provided with detachable geotextiles plug, and the detector tube Lower Half is offered through hole along body longitudinal separation.
The beneficial effects of the utility model are, can effectively detect and control grouting and reinforcing pressure by this device, are very easy to construction, and are simple to operate, with low cost.
Description of drawings
This manual comprises following two width of cloth accompanying drawings:
Fig. 1 is the use view of the existing roadbed grouting and reinforcing of the utility model pressure control easy device;
Fig. 2 is the longitudinal plane structure signal of the existing roadbed grouting and reinforcing of the utility model pressure control easy device.
Member shown in the figure, toponym and corresponding mark: existing embankment 1, embankment surface layer of subgrade bed 2, detector tube 3, through hole 3a, geotextiles plug 4.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, the existing roadbed grouting and reinforcing of the utility model pressure control easy device, comprise along circuit longitudinal separation and be arranged at detector tube 3 under the embankment surface layer of subgrade bed 2, the two-port of detector tube 3 is provided with detachable geotextiles plug 4, and detector tube 3 Lower Halves are offered through hole 3a along body longitudinal separation.The spacing distance of each detector tube 3 on circuit is vertical is generally 0.3～0.4m.This device utilizes detector tube 3 to check that existing embankment 1 slip casting effects and pressure is whether enough and transfinite, and geotextiles plug 4 sealing detector tubes 3 mouths of pipe guarantee that grouting pressure keeps balance, can effectively detect and control grouting and reinforcing pressure, be very easy to construction, simple to operate, with low cost.
With reference to Fig. 2 and Fig. 3, described detector tube 3 diameters are 0.1～0.15m, and through hole 3a diameter is 0.05～0.08m, and spacing 0.1～0.2m is the blossom type setting.Be reducing construction cost farthest, the detector tube 3 preferred pvc pipe materials that adopt are made.
The concrete using method of the existing roadbed grouting and reinforcing of the utility model pressure control easy device is as follows: detector tube 3 is put in boring under the subgrade bed top layer, and through hole 3a part is downward, mouth of pipe geotextiles plug 4 sealings.The slip casting of in 3 times existing embankments 1 of detector tube, holing, strengthen step by step grouting pressure, use reinforcing bar with hairbrush to stretch into detector tube 3 interior inspections under every stage pressure whether object with injection slurry is arranged, as without then adding the one-level grouting pressure until can detect the slip casting object time, suitably reduce grouting pressure and carry out grouting and reinforcing.If for coming to nothing under come to nothing under the ruggedized construction thing grouting and reinforcing such as the high-speed railway subgrade stake plated construction etc., around then only the need sealing is come to nothing, adopt short detector tube 3 to be communicated with the part of coming to nothing in the both sides of coming to nothing, the mouth of pipe seals with geotextiles plug 4, to the part slip casting of coming to nothing, when the injection slurry bulging appears in detector tube 3 mouth of pipe geotextiles plugs 4, then stop the grouting pressure rising and carry out grouting and reinforcing, when entering, slip casting stops at need slip casting.
Some principles of the above the existing roadbed grouting and reinforcing of the utility model pressure control easy device that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every corresponding modify that might be utilized and equivalent all belong to the claim that the utility model is applied for.
