Description
Technical field
The present invention relates to underground construction frozen construction equipment, be specifically related to a kind of freezing pipe slip casting check device.
Background technology
Underground construction adopts construction freezing method, annular space between freezing borehole and freezing pipe forms the conduit pipe with hydraulic connection, operation field generation gushing water can be caused on the one hand, have a strong impact on construction safety, the water of another aspect shallow water flow and the easy conducting of sand are to deep, cause superficial part water resource utility model, therefore need to carry out solid pipe water shutoff process to freezing hole.At present, the solid pipe water shutoff process of freezing hole is divided into the solid pipe water shutoff process of slip casting in advance and the solid pipe water shutoff process of later stage slip casting, the solid pipe water shutoff process of slip casting is in advance under freezing pipe before pipe, drilling slurry within the scope of certain altitude above at the bottom of hole is replaced into the cement grout with certain slow setting time, by the solidification of cement grout, realize the cementing of freezing pipe and stratum, block conduit pipe, this kind of solid pipe water shutoff process construction has strict requirement to the performance of cement grout and the lower pipe time of freezing pipe, complex process, efficiency of construction is low, and easily causes hole wall collapse; The solid pipe water shutoff process of later stage slip casting uses more generally perforation, bored grouting technology, namely after frozen construction terminates, freezing pipe open-work is carried out grouting filling to freezing pipe outer ring space, complete solid pipe water shutoff process, no matter be freezing pipe perforation or boring, all need very difficult complex operations, have higher requirement to construction equipment and construction technology, construction cost is also relatively high.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of freezing pipe slip casting check device is provided, this device is used for the solid pipe water shutoff process of freezing hole, solid pipe water shutoff process construction technology can be simplified, reduce the requirement to construction equipment and construction technology, improve efficiency of construction, save operating expenses, ensure construction quality.
The technical scheme realizing above-mentioned purpose is: a kind of freezing pipe slip casting check device, it has outer tube and is placed in the interior pipe in this outer tube, the lower end-plate simultaneously forming this outer tube and interior pipe lower end closed is provided with in the lower end of described outer tube and interior pipe, be provided with spring in described interior pipe and be placed in the spheroid above this spring, the upper end of described outer tube is provided with upper-end closing plate, the center of this upper-end closing plate is provided with the grout outlet coordinated with described spheroid, described outer tube is provided with extravasating hole and the rubber sleeve for this extravasating hole of shutoff, the top and bottom of this rubber sleeve arrange rubber sleeve retainer ring respectively.
Technical scheme of the present invention also comprises: be provided with freezing pipe in the upper end of described outer tube and connect correcting iron hoop.
This freezing pipe slip casting check device, structure is simple, facilitates processing and fabricating.
This freezing pipe slip casting check device is used for the solid pipe water shutoff process of freezing hole, can ensure carrying out smoothly and effective mutual flowing stoping slurries inside and outside freezing pipe under non-Construction State of slip casting, ensure solid pipe water shutoff process construction quality.
This freezing pipe slip casting check device is used for the solid pipe water shutoff process of freezing hole, can simplify solid pipe water shutoff process construction technology, reduce the requirement to construction equipment and construction technology, improve efficiency of construction, save operating expenses.
Accompanying drawing explanation
Accompanying drawing is this freezing pipe slip casting check device structural representation.
Detailed description of the invention
The invention will be further described with embodiment by reference to the accompanying drawings.
As accompanying drawing, this freezing pipe slip casting check device has outer tube 1, and this outer tube 1 adopts and the Inner of the freezing pipe 11 of use, body that external diameter is identical.In outer tube 1, arrange interior pipe 2, interior pipe 2 is placed in the center of outer tube 1, and the length of interior pipe 2 is less than the length of outer tube 1.The lower end-plate 3 simultaneously forming this outer tube 1 and interior pipe 2 lower end closed is provided with in the lower end of outer tube 1 and interior pipe 2.During concrete enforcement, lower end-plate 3 also can be arranged to convex cone plate downwards, to facilitate lower pipe.The spheroid 5 being provided with spring 4 in interior pipe 2 and being placed in above this spring, the diameter of spheroid 5 and the internal diameter of interior pipe 2 are slidably matched.Be provided with upper-end closing plate 6 on the top of outer tube 1, the center of this upper-end closing plate 6 is provided with the grout outlet coordinated with spheroid 5.As accompanying drawing embodiment, the grout outlet coordinated with spheroid 5 is arranged to taper seat, to ensure the good fit of spheroid 5 and grout outlet; Upper-end closing plate 6 can adopt a upper plate body and a lower body assembly welding shaping, to facilitate processing, save material.One section of tube wall of outer tube 1 circumferentially with is axially uniformly distributed extravasating hole 7, and this extravasating hole 7 is circular port.Outer tube 1 is positioned at the rubber sleeve 8 be provided with outside the body with extravasating hole 7 position for shutoff extravasating hole 7, and the top and bottom of this rubber sleeve 8 arrange rubber sleeve retainer ring 9 respectively, and retainer ring 9 is square-section torus, is weldingly fixed on outer tube 1.
The lower end that this freezing pipe slip casting check device is welded on freezing pipe 11 uses, and during welding, the upper end of outer tube 1 is docked with the lower end of freezing pipe 11.
As accompanying drawing embodiment, this freezing pipe slip casting check device arranges freezing pipe and connects correcting iron hoop 10 in the upper end of outer tube 1, and the internal diameter of this correcting iron hoop 10 and the external diameter of freezing pipe 11 and outer tube 1 coincide, and by being welded to connect.
This freezing pipe slip casting check device is used for after frozen construction terminates, and carries out grouting filling before frost wall thaws to freezing pipe outer ring space.In slip casting process, the pressure that in freezing pipe, slurries act on spheroid 5 is greater than the pressure that spring 4 acts on spheroid 5, slurries press spheroid 5 and move down, grout outlet is opened, slurry is made to enter in outer tube 1, be stressed effect simultaneously, enters slurries in outer tube 1 and wash rubber sleeve 8 open by extravasating hole 7 and enter annular space between freezing pipe and freezing borehole, carry out the solid pipe water shutoff construction of slip casting of freezing hole.When the slip casting grouting behind shaft or drift lining equipment completing annular space is out of service, pressure inside and outside freezing pipe may be uneven, but now spheroid 5 and rubber sleeve 8 reset, the slurries in the slurries in freezing pipe and freezing pipe outer ring space are kept apart, thus ensure completing smoothly of the solid pipe water shutoff of freezing hole.
This freezing pipe slip casting check device is double blocking to the blocking-up of slurries inside and outside freezing pipe, has higher security reliability.
