Description
Technical field
The utility model relates to shield structure applied technical field, especially a kind of shield structure ending hermetically-sealed construction.
Background technology
At present, shield machine shield tail sealing system is one of critical system of normally tunneling of shield machine, the security incident that shield method tunnel construction occurs usually occurs in shield tail instead of at shield machine head, shield tail generation seepage, mud and water balance and grouting quality will be destroyed, and pollute the work plane of shield duct piece installation, install to section of jurisdiction and bring inconvenience, have a strong impact on the normal driving of shield structure, if generation seepage, construction speed will be badly influenced, so avoid occurring that spillage is vital task in shield driving and key technology, and protect the intact of tail sealing to be the prerequisite ensureing not spillage.
Prior art can not meet the needs of people, and for making up prior art deficiency, the bearing capacity that the utility model aims to provide this structure a kind of is strong, and anchor ring is smooth, and seam is closely connected, good sealing effect, practical shield structure ending hermetically-sealed construction.
For achieving the above object, the utility model by the following technical solutions: a kind of shield structure ending hermetically-sealed construction, at least comprises shield tail, slip casting passage, shield ventral brush, water passage, section of jurisdiction, shield shell, pressing plate, seal grease, steel spring plate and bolt; Be respectively arranged with shield tail and shield ventral brush in slip casting passage top and bottom, and slip casting passage upper and lower surface respectively with shield tail and shield ventral brush compact siro spinning technology; Described shield ventral brush soffit is provided with water passage; The soffit of water passage is provided with section of jurisdiction, and the soffit of water passage and section of jurisdiction close adhesion; The external surface of section of jurisdiction is provided with shield shell, and the right-hand member of described shield shell is provided with pressing plate; Described pressing plate is bolted on shield shell on the surface; Described seal grease spreads upon pressing plate and shield shell joint touches cross-stitch place; The horizontal right-hand member of pressing plate is provided with steel spring plate, and described steel spring plate is by bolt and shield shell compact siro spinning technology.
As optimisation technique scheme of the present utility model: be provided with shield ventral brush described in shield ventral brush between described slip casting passage and water passage and closely wrap up the whole circumference in section of jurisdiction; Described shield shell soffit is provided with pressing plate and steel spring plate and is bolted.
Compared with prior art, the beneficial effects of the utility model are: this structure is provided with shield ventral brush described in shield ventral brush and closely wraps up the whole circumference in section of jurisdiction this structure bearing capacity is strengthened between slip casting passage and water passage, shield ventral brush not easily comes to harm, outside pressing plate, face scribbles seal grease, make sealing effectiveness better, seam is closely connected, and slurries can not enter Tu Cang, described structure is practical, is easy to promote the use of.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 4, in the utility model embodiment, a kind of shield structure ending hermetically-sealed construction, at least comprises shield tail 1, slip casting passage 2, shield ventral brush 3, water passage 4, section of jurisdiction 5, shield shell 6, pressing plate 7, seal grease 8, steel spring plate 9 and bolt 10; Be respectively arranged with shield tail 1 and shield ventral brush 3 in slip casting passage 2 top and bottom, and slip casting passage 2 upper and lower surface respectively with shield tail 1 and shield ventral brush 3 compact siro spinning technology; Described shield ventral brush 3 soffit is provided with water passage 4; The soffit of water passage 4 is provided with section of jurisdiction 5, and the soffit of water passage 4 and section of jurisdiction 5 close adhesion; The external surface of section of jurisdiction 5 is provided with shield shell 6, and the right-hand member of described shield shell 6 is provided with pressing plate 7; Described pressing plate 7 is fixed on shield shell 6 on the surface by bolt 10; Described seal grease 8 spreads upon pressing plate 7 and contacts cross-stitch place with shield shell 6; The horizontal right-hand member of pressing plate 7 is provided with steel spring plate 9, and described steel spring plate 9 is by bolt 10 and shield shell 6 compact siro spinning technology.
As optimisation technique scheme of the present utility model: be provided with shield ventral brush 3 between described slip casting passage 2 and water passage 4; Described shield ventral brush 3 is the whole circumference in parcel section of jurisdiction 5 closely; Described shield shell 6 soffit is provided with pressing plate 7 with steel spring plate 9 and is connected by bolt 10.
General principle of the present utility model: the mud that described structure injects suitable pressure in the muddy water cabin of support ring previous one dividing plate makes it form mud film in excavation face, the supporting front soil body, and by being arranged on the large knife cutting soil body top layer mud film in front, after mixing with muddy water, form high-density slurry, then by slush pump and pipeline slurry transportation to floor treatment, the fundamental requirement that mud and water balance is slurry shield machine driving is set up in muddy water cabin and between face, in addition due in shield tunneling process, the section of jurisdiction back of the body is adopted to fill out dual-fluid synchronous slip casting mode to fill the gap of section of jurisdiction and country rock, thus reach reduction stratum settlement, restriction Segment displacement and distortion, improve structural stability, strengthen the object of tunnel water proofing performance.
