Description
Technical field
The utility model relates to municipal waterproof construction field, and the hole waterproof in particularly a kind of pipe-jacking project is ended sizing device.
Background technology
Along with developing rapidly of China's municipal engineering, pipe-jacking project enters a fast-developing period.Several modes such as the job practices of domestic underground municipal engineering mainly contains that open cut, tunneling, lid are dug, shield structure and push pipe.Compare with other several worker's methods, construction by pipeline jacking method has obvious superiority, and its range of application more and more widely.Push pipe slip casting for reducing push pipe pressure, guarantees that the safety of jacking construction and surrounding enviroment has important effect as a key technology of pipe jacking method.
At present in municipal engineering and underground engineering field, particularly in the pipe jacking method engineering, the follow-up external diameter of pipe of push pipe guide external diameter of pipe is big, the outer space that exists of pipe in the push pipe process, when in weeping formation, carrying out jacking construction, underground water to walling crib mouth seepage, formed aquaporin from the space outside pipe, may cause accidents such as landslide.In order to reduce tube wall external friction resistance and filling tube wall outer void, often outside tube wall, inject bentonite slurry in the push pipe process, and bentonite slurry flows out from the push pipe outside easily, be unfavorable for that sealing ends slurry and drag reduction.
The utility model content
The purpose of this utility model provides a kind of waterproof grout-stopping device at jacking pipe entry portal, the technical problem of solve walling crib mouth sealing in the jacking construction process, ending slurry.
For achieving the above object, the utility model adopts following technical scheme.
This waterproof grout-stopping device at jacking pipe entry portal is fixedlyed connected with walling crib, it is characterized in that: be fixed with brush holder on the described walling crib, the brush holder inboard is fixed with walling crib brush and oil fuel tube; The walling crib brush ring is to being arranged between push pipe and the brush holder, the cast sandwich that the walling crib brush is made up of about two layers of thin iron plate and inner elastic wire, the brush body of walling crib brush is positioned at the well head place, brush body is adjacent to the outer wall of push pipe to push pipe bending, brush, and block space between push pipe and the country rock, and also being fixed with oil fuel tube on the brush holder, the outlet of oil fuel tube extends in the interlayer of walling crib brush, the inside pipe wall of push pipe is installed with Grouting Pipe to managing outer wall, and the outlet of Grouting Pipe extends in the space.
Described brush holder can be brushed by the bolt walling crib.
Described brush holder can be to be surrounded between cast overall structure steel plate that the push pipe periphery is provided with or each section to adopt welding or bolt connection.
Described brush holder can be steel plate or the steel bracket that segmentation is provided with.
The brush of described walling crib brush is a plagiocephaly, oblique being adjacent to of outer wall of it and push pipe, and the angle of inclination is less than 90 ° and greater than 0 °.
The utlity model has following characteristics and beneficial effect.
The utility model has been installed walling crib brush hole sealing device at the walling crib mouth in the push pipe process, and by grouting port injection colloid substance in the walling crib brush, after push pipe enters walling crib, in push pipe, inject drag reducer synchronously to the space by Grouting Pipe, compressing walling crib brush, make the walling crib brush be close to the push pipe external surface, thereby reach the purpose that the hole waterproof is ended slurry.This device has following some advantage.
(1), adopt this device can stop water from the space, to ooze out, avoid surface settlement, reduce the risk of surface collapse.
(2), in the long-distance pipe jacking process, to pipe is outer when injecting bentonite slurry, adopt this device can stop slurries from the space, to spill, raising slip casting drag-reduction effect.
(3), this device is installed after, need not manually-operated, time saving and energy saving, accelerate construction progress greatly.
(4), for big density push pipe, this device can reuse, cost is low, economic environmental protection.
