Abstract
The invention relates to a construction method of a sealing ring of the duct piece wall of a shield inclined shaft. The method is completed according to the following steps of 1, making the sealing ring: installing two annular air bags at the two sides of a duct piece grouting hole, forming an inflating hole communicated to the inner side of a duct piece in each annular air bag, installing two protection plates on each air bag, and overlapping the protection plates in the shield tail sealing brush sliding direction; 2, after the duct piece is dragged out from the shield tail, inflating the two air bags so that the air bags are tightly extruded with the surrounding rock, and a sealed space is formed between the two air bags; 3, injecting cement-water glass dual-liquid slurry into the sealed space between the two air bags to form the sealing ring, and exhausting air in the air bags after dual-liquid slurry solidification; and 4, installing one sealing ring at a certain distance, and then performing single-liquid slurry filling between the two sealing rings. The sealing ring can be used for the slurry backfilling of single-liquid slurry and the like under the great-slope and flowering water conditions. In addition, the construction method has the advantages that the operation is simple; the construction efficiency is high; and the cost is low, and the like.
Description
Technical field:
The invention belongs to a kind of construction techniques, particularly the construction method of shutoff ring after the wall of a kind of shield structure inclined shaft section of jurisdiction.
Background technology:
At present, shield-tunneling construction has been very general at engineering fields such as traffic, municipal administration, water power, and along with maturation and the development of shield technique, this construction method is applied to coal mine inclined shaft construction gradually.
Shield structure coal mine inclined shaft due to its gradient comparatively large, section of jurisdiction wall rear slurry very easily runs off along the gradient toward Tu Cang, and it is large to fill difficulty after wall.Common cement-sodium silicate double liquid shutoff ring is under the gradient and dynamic regimen condition, and plugging effect is undesirable.
Summary of the invention:
Object of the present invention is just to provide the construction method of shutoff ring after the wall of a kind of shield structure inclined shaft section of jurisdiction, and the method can solve slurries losing issue, for filling full providing safeguard after the wall of section of jurisdiction.
As above conceive, technical scheme of the present invention is: the construction method of shutoff ring after the wall of a kind of shield structure inclined shaft section of jurisdiction, is characterized in that: complete according to the following step:
1. shutoff ring is made: arrange bipassage ring to air bag in injected hole both sides, section of jurisdiction, hoop air bag leaves air-filled pore and lead to inside section of jurisdiction, each air bag is arranged twice guard shield, guard shield overlaps along tail sealing brush line of travel;
2., after tail shield is hauled out in section of jurisdiction, by twice airbag aeration, make it and country rock jam-packed, thus form one seal cavity between twice air bag;
3. inject cement-sodium silicate double liquid toward the seal cavity between twice air bag, form one shutoff ring, after dual slurry is solidified, by gas emptying in air bag;
4. one above-mentioned shutoff ring be set at a certain distance, between twice shutoff ring, then carry out single liquid slurry fill.
Above-mentioned guard shield is connected with section of jurisdiction connecting bolt.
The present invention has following advantage and good effect:
1, the present invention arranges bipassage ring to air bag in injected hole both sides, section of jurisdiction, forms one hoop seal cavity, in this space, inject cement-sodium silicate double liquid after inflation, forms shutoff ring.The slurries such as single liquid slurry backfill after section of jurisdiction wall under utilizing this shutoff ring can realize heavy grade and river channels, efficiently solves the problem of shutoff circulating application work difficulty under dynamic ramp shaped state under water.
2, the present invention is damaged by tail sealing brushing to prevent hoop air bag, and each air bag arranges twice guard shield, and guard shield along tail sealing brush line of travel overlap joint, thus extends the application life of shutoff ring, improves construction quality.
3, the present invention have operation simple and easy, the advantages such as efficiency of construction is high, with low cost.
Accompanying drawing illustrates:
Fig. 1 is the schematic diagram of shutoff ring of the present invention;
Fig. 2 is construction sectional drawing of the present invention.
In figure: 1, section of jurisdiction; 2, injected hole; 3, air-filled pore; 4, air bag; 5, guard shield A; 6, guard shield B; 7, connecting bolt; 8, country rock; 9, dual slurry shutoff ring slip casting space.
Detailed description of the invention:
A construction method for shutoff ring after the wall of shield structure inclined shaft section of jurisdiction, completes according to the following step:
1. shutoff ring is made: in section of jurisdiction injected hole 2 both sides, bipassage ring is set to air bag 4, leaves air-filled pore 3 on the upside of hoop air bag and lead to inside section of jurisdiction.In order to prevent hoop air bag from being damaged by tail sealing brushing, each air bag arranges twice guard shield 5,6, and guard shield is connected with section of jurisdiction connecting bolt 7, and guard shield overlaps along tail sealing brush line of travel; (as shown in Figure 1)
2., after tail shield is hauled out in section of jurisdiction, by air-filled pore 3, air bag 4 is inflated, air bag is expanded and with country rock 8 jam-packed, form one hoop seal cavity 9; (as shown in Figure 2)
3. fill cement-sodium silicate double liquid toward seal cavity 9, form shutoff ring;
4. after cement-sodium silicate shutoff ring solidifies, by air-filled pore 3 by gas emptying in air bag;
A shutoff ring (as 8 ~ 10 rings) is 5. set at a certain distance, single liquid slurry backfill carry out section of jurisdiction wall between two shutoff rings after.
The present invention utilizes air bag temporary sealing, carries out cement-sodium silicate double liquid shutoff circulating application work, effectively solves the dynamic work of a ramp shaped state shutoff circulating application under water difficult problem not easily, operates simple and easy, efficient.
