Abstract
The invention discloses a method for preventing sand gushing in shield tunneling construction. A water stop arch plate formed by compounding rubber and a steel plate is clamped and pressed between the lower part of the front end of a last ring duct piece and a shield tunneling jack, so that the circumferential and radial sealing of the inner lower part of a shield tunneling machine is realized; and a sponge strip is filled between the lower part of the last ring duct piece and a case of the shield tunneling machine for filtering silt and slurry aggregate. The method has the advantages that the silt can be filtered and blocked; the adverse influence of sand gushing and slurry leakage on the shield tunneling construction is prevented; the cleanness of work environment at the shield tail is maintained; the labor and the materials used for mud cleaning at the shield tail are further reduced; the construction cost is reduced; meanwhile, the shield tunneling is enabled to be performed on schedule; and the construction period is not influenced.
Description
Technical field
The present invention relates to a kind of method for shield-tunneling construction, particularly a kind of method preventing shield-tunneling construction from gushing sand.
Background technology
Along with economic development, Underground Rail Transit engineering is more and more many.When adopting shield machine construction subway tunnel, there will be the problem that shield ventral brush damages, after shield ventral brush damages, being difficult to avoid having gush sand or the generation of spillage phenomenon on a small quantity at shield machine shield tail.If do not take corresponding measure, gush sand or spillage can be built up at shield tail place, affect shield-tunneling construction environment, severe patient can affect the shield structure duration, causes normally tunneling.Timely cleaning shield tail silt needs a large amount of man power and materials, and then can cause the increase of construction cost.
Summary of the invention
The present invention provides a kind of method preventing shield-tunneling construction from gushing sand for solving in known technology the technical problem that exists.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is: a kind of method preventing shield-tunneling construction from gushing sand, adopt the sealing arc plate in the end clamping rubber and steel plate compound between an endless tube sheet front lower portion and shield structure jack, realize circumference and the radial seal of bottom in shield machine, adopt filling sponge bar between the bottom of an in the end endless tube sheet and the shell of shield machine, filter silt and slurries aggregate.
Described sealing arc plate is by billet and rubber mat plate is bonding forms, described billet contacts with described shield structure jack, described rubber mat plate contacts with last endless tube sheet described, the groove turned over before the outer rim place of described rubber mat plate is formed, the groove of described rubber mat plate is wrapped in the outer rim place of described billet; Described composite water-stop arc plate contacts with being formed inside the shell of shield machine to seal.
Described composite water-stop arc plate is formed by multiple assembled unit spliced, and the billet inner edge of each assembled unit is equipped with manpower handle.
Angle corresponding to described composite water-stop arc plate is 120 °.
The advantage that the present invention has and good effect are: composite water-stop arc plate adopts rubber bound edge to be sealed in inside the outer casing underpart of shield machine, realize the circumferential seal of bottom in shield machine, the front end of a composite water-stop arc plate compacting in the end endless tube sheet is made by the pressure of jack in tunneling process, realize the radial seal of bottom in shield machine, adopt structured filter silt and the slurries aggregate of filling sponge bar, in sum, the present invention can filter and intercept silt, prevent gushing hourglass and starch the harmful effect that shield-tunneling construction is caused, shield tail working environment is kept to clean, and then the man power and material that the clear mud of saving shield tail uses, save construction cost, ensure that shield structure can tunnel as scheduled, the duration is unaffected simultaneously.

Detailed description of the invention
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 ~ Fig. 4, a kind of method preventing shield-tunneling construction from gushing sand, adopt the sealing arc plate 1 in the end clamping rubber and steel plate compound between endless tube sheet 3 front lower portion and shield structure jack 4, realize circumference and the radial seal of bottom in shield machine, adopt filling sponge bar 2 between the bottom of an in the end endless tube sheet 3 and the shell 5 of shield machine, filter silt and slurries aggregate.
In the present embodiment, described sealing arc plate 1 is by billet 1-1 and rubber mat plate 1-2 is bonding forms, described billet 1-1 contacts with described shield structure jack 4, described rubber mat plate 1-2 contacts with last endless tube sheet 4 described, the groove turned over before the outer rim place of described rubber mat plate 1-2 is formed, the groove of described rubber mat plate 1-2 is wrapped in the outer rim place of described billet 1-1; Described composite water-stop arc plate 1 contacts with being formed to seal inside the shell 5 of shield machine.Conveniently install, described composite water-stop arc plate 1 is formed by multiple assembled unit spliced, and the billet inner edge of each assembled unit is equipped with manpower handle 1-3.Angle corresponding to described composite water-stop arc plate 1 is 120 °.Above-mentioned billet 1-1 adopts the thick steel plate for 10mm to be formed, and above-mentioned rubber mat plate 1-2 adopts the thick rubber tile for 12mm to be formed.
Although be described the preferred embodiments of the present invention by reference to the accompanying drawings above; but the present invention is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, can also make a lot of form, these all belong within protection scope of the present invention.
