Abstract
Draining slip casting structure, effectively to carry out grouting and reinforcing to high-pressure water-enriched goaf.Be included in interval in goaf lay and pierced the inlet well pushed up in goaf by ground, be provided with in described inlet well and reach Grouting Pipe at the bottom of hole and gutter by its upper end extension, the outer end of Grouting Pipe, gutter is connected with grouting device, dewatering installation respectively.The perisporium of gutter lays perforate, its outer wall has wrapped permeable geotextiles.
Description
Technical field
The utility model relates to geotechnical engineering, particularly for draining slip casting structure that high-pressure water-enriched goaf grouting is reinforced.
Background technology
Grouting reinforcement technique is extensive use in engineering, but when carrying out grouting and reinforcing in high-pressure water-enriched goaf, adopt conventional grouting strengthening method then to there will be some problems, make to reinforce or grouting consolidation effect poor, such as: the water pressure on high-pressure water-enriched stratum is large, and slurries are difficult to press-in; Diluted after rich water cavity slurries flow into, be difficult to solidify and maybe can not solidify; Goaf scope is large, and injection slurry Flowing Hard is to form effective reinforcing body etc.For this reason, a kind of new slip casting structure of urgent needs solves problems.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of draining slip casting structure, effectively to carry out grouting and reinforcing to high-pressure water-enriched goaf.
The utility model solves the technical scheme that its technical problem adopts:
Draining slip casting structure of the present utility model, be included in interval in goaf lay and pierced the inlet well pushed up in goaf by ground, it is characterized in that: be provided with in described inlet well and reach Grouting Pipe at the bottom of hole and gutter by its upper end extension, the outer end of Grouting Pipe, gutter is connected with grouting device, dewatering installation respectively; The perisporium of gutter lays perforate, its outer wall has wrapped permeable geotextiles.
The beneficial effects of the utility model are, in inlet well, arrange gutter and Grouting Pipe simultaneously, utilize gutter to extract underground high-voltage water, reduce water pressure and are beneficial to mortar depositing construction, utilize Grouting Pipe to carry out stratum grouting and reinforcing.This structure has easy construction, economic dispatch feature, has wide popularizing application prospect.
Accompanying drawing explanation
This manual comprises following three width accompanying drawings:
Fig. 1 is the structural representation of the utility model draining slip casting structure.
Fig. 2 is the stereogram of gutter in the utility model draining slip casting structure.
Fig. 3 is the sectional view of gutter in the utility model draining slip casting structure.
Component name shown in figure and corresponding mark: inlet well 10, Grouting Pipe 20, gutter 30, perforate 31, permeable geotextiles 32.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1, draining slip casting structure of the present utility model, is included in interval in goaf and lays and pierced the inlet well 10 pushed up in goaf by ground.Be provided with in described inlet well 10 and reach Grouting Pipe 20 at the bottom of hole and gutter 30 by its upper end extension, the outer end of Grouting Pipe 20, gutter 30 is connected with grouting device, dewatering installation respectively.With reference to Fig. 2 and Fig. 3, the perisporium of gutter 30 is laid perforate 31, its outer wall has wrapped permeable geotextiles 32.
With reference to Fig. 1, the utility model 10 is arranging gutter 30 and Grouting Pipe 20 in inlet well simultaneously, underground high-voltage water is extracted by gutter 30, initiatively reduce water pressure and be beneficial to mortar depositing construction, stretch into the guide pipe of inlet well 10 as Grouting Pipe 20, utilizing gutter 30 groundwater abstraction particularly slurries can be avoided to be diluted after empty underground water in addition can not solidify simultaneously; Perforate 31 is beneficial to underground water and enters in gutter 30, and permeable geotextiles 32 can invariably descend earth and slurries to enter gutter 30.Grouting Pipe 20, as slurries carrier pipe, carries out stratum grouting and reinforcing from the bottom up.This structure has easy construction, economic dispatch feature, has wide popularizing application prospect.
With reference to Fig. 2 and Fig. 3, perforate 31 is that blossom type is laid along the perisporium of gutter 30.With reference to Fig. 1, described Grouting Pipe 20, gutter 30 are connected in bottom, and under grouting pressure effect, both can throw off bonding strength.Described gutter 30, after slip casting completes, adopts gravity flow slurries filling envelope.
With reference to Fig. 1, the sequence of construction that draining slip casting structure of the present utility model is used for high-pressure water-enriched stratum grouting and reinforcing is: form inlet well 10 → Grouting Pipe 20 to be connected with bottom gutter 30 → Grouting Pipe 20 and gutter 30 stretch into bottom inlet well 10 → gutter 30 continue pump drainage underground water → groundwater pressure be reduced to certain pressure grouting behind shaft or drift lining pipe 20 start the hoisting grouting pipe 20 of slip casting → slowly also lasting slip casting → slip casting complete and extract the Grouting Pipe 20 → slurries that flow automatically and clog gutter 30.
Some principles of the above the utility model draining slip casting structure that just explains through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the utility model is applied for.
