Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following instance for illustration of the utility model, but is not used for limiting scope of the present utility model.
With reference to shown in Fig. 1 and 2, slip casing by pressure structure of the present utility model, comprising: container 1, Grouting Pipe 3 and stack 2.Container 1 is pipe fitting or hole, container 1 level, inclination or vertically place, and in the present embodiment, container 1 horizontal positioned, the side of container 1 has a hole, and hole is provided with hush panel 4.Preferably, hush panel 4 and container 1 are bolted or are welded to connect, and make hush panel 4 close hole.Hush panel 4 is provided with slip casting through hole 42 and exhaust hole 41, and in the present embodiment, the height of slip casting through hole 42 is lower than exhaust hole 41.One end of Grouting Pipe 3 is connected with slip casting through hole 42, and the other end of Grouting Pipe 3 is for connecting slip casting machinery.One end of stack 2 is connected with exhaust hole 41, and the other end of stack 2 is provided with reading ball valve 8.The body of stack 2 is provided with holds pressure ball valve 6, holds between pressure ball valve 6 and reading ball valve 8 and is provided with pressure meter 7.Wherein, the downstream end of stack 2 is higher than container 1, and namely the outlet of reading ball valve 8 is higher than container 1.
Further, Grouting Pipe 3 is provided with slip casting ball valve 5.After slip casting completes, close slip casting ball valve, to ensure that in container, grouting pressure remains unchanged.Be convenient to the telephone-moving after slip casting completes of slip casting machinery and treat that slip casting container carries out slip casting to the next one, do not need the curing compound solidification treated in container.
Further, one end that stack 2 is connected with exhaust hole 41 is provided with elbow 21, and elbow 21 stretches in container 1, and the port of elbow 21 is near the inside wall top of container 1.According to the mechanics law of fluid, the pressure in stack is identical with the pressure of entrance location, and the port of elbow comparatively accurately can record the force value of container side wall position near the sidewall of container.Being full of by slurries for ensureing to complete in slip casting container, reducing the container inside aperture that in container, residual air causes as far as possible, part should as far as possible near container inner wall highest point within container for stack, stay gap need ensure the normal discharge of gas in container.
Slip casing by pressure method of the present utility model, comprises the following steps:
Step S1: open slip casting machinery and inject curing compound in container, holds pressure ball valve simultaneously and reading ball valve is held open.Grouting Pipe and slip casting are mechanically connected, open reading ball valve and hold pressure ball valve, open slip casting machinery and inject curing compound in container, observed reading ball valve simultaneously.
Step S2: after reading ball valve starts plasma discharge, closes reading ball valve, continues to inject curing compound, observes pressure meter simultaneously, when the grouting pressure of pressure meter display reaches designing requirement, closes and holds pressure ball valve and slip casting machinery.
Step S3, closes slip casting ball valve, is separated slip casting machinery and Grouting Pipe, removes slip casting machinery.
Slip casing by pressure structure of the present utility model and grouting method thereof, use pressure meter can grouting pressure in Measurement accuracy container, accurately control the pressure in container, avoid pressure excessive damage container or pressure too small, eliminate container inner pore comparatively large, full problem cannot be filled.
Curing compound described in the utility model can adopt cement paste or other sealing materials.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
