Description
Technical field
The present invention relates to open caisson construction fields, more particularly to a kind of caisson cutting edge with sealing brush.
Background technique
When carrying out open caisson construction on rear side of some walls in the biggish ground place of resistance, sink to make open caisson meet self weight
It is required that frictional resistance auxiliary is sunk after reducing wall using the method for support with backfilling mud lubrication, in practice of construction, due to blade foot
Can not be completely closely connected with periphery Rock And Soil, mud can penetrate into well from blade foot bottom after wall, influence open caisson construction；In addition, adopting
It also needs to fill the water when carrying out shaft sinking with some road heading machineries, in well and carries out mud circulation deslagging, inside and outside the borehole wall after intercommunication also
Meeting so that interior outside slurry liquid face height change, influence construction or retaining wall effect, cause larger engineering accident, therefore, need
A kind of caisson cutting edge with sealing function is designed, the connection of outside mud in caisson wall is blocked.
Summary of the invention
In order to solve the technical problem in background technique, the present invention discloses a kind of caisson cutting edge with sealing brush, in open caisson
Blade foot step surface sealing brush arranged below blocks the connection of outside mud in caisson wall.
In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions:
A kind of caisson cutting edge with sealing brush, including mud ditch after Rock And Soil, wall after caisson cutting edge, wall, further include sealing brush, are sunk
Rock And Soil side is step structure after well blade foot Lin Bi, ground body side surface and ground after wall after the above caisson cutting edge Lin Bi of step surface
It is mud ditch after wall between body, it is close being equipped between Rock And Soil after ground body side surface after the following caisson cutting edge Lin Bi of step surface and wall
Envelope brush, sealing brush include brush teeth and fixed bottom plate, and fixed bottom plate one side is connect with ground body side surface after caisson cutting edge Lin Bi, solid
Determine to be equipped at intervals with several brush teeths on the another side of bottom plate, brush teeth includes several bristles, bristle intermediate plate, and bristle one end is by bristle intermediate plate
It grips, bristle intermediate plate is fixed on fixed bottom plate, and bristle exposes outside bristle intermediate plate far from one end of bristle intermediate plate.
A kind of caisson cutting edge with sealing brush, is pasted on ground body side surface after Lin Bi below caisson cutting edge step surface
It closes and is equipped with pre-buried fixation steel plate.
A kind of caisson cutting edge with sealing brush, fixed bottom plate are welded on pre-buried fixation steel plate or by fixed spiral shells
Bolt is fixed on pre-buried fixation steel plate.
A kind of caisson cutting edge with sealing brush, the length of bristle are greater than rock after caisson cutting edge step surface or less Lin Bi
The distance between Rock And Soil behind soil body side and wall.
A kind of caisson cutting edge with sealing brush, bristle and bristle intermediate plate are made of metal material.
Due to the adoption of the above technical scheme, the present invention have it is following the utility model has the advantages that
1. the present invention arranges the sealing steel brush of certain altitude below caisson cutting edge step surface, prevent after wall mud from blade foot bottom
Penetrating into influences construction in well, meanwhile, it also prevents because mud leaks the mud off caused failure, the deformation of periphery ground after wall,
And the frictional resistance after sealing steel brush and open caisson wall between ground is smaller, will not impact to well sinking in open caisson construction；
It is needed to fill the water in well when carrying out mud circulation deslagging shaft sinking 2. the present invention is applied, not intercommunication inside and outside the borehole wall avoids
Because intercommunication causes in the borehole wall outside slurry liquid face height to change influence construction or retaining wall effect inside and outside the borehole wall.
Detailed description of the invention

Specific embodiment
By the following examples can the detailed explanation present invention, the open purpose of the present invention is intended to protect model of the present invention
Enclose all interior technological improvements.
A kind of caisson cutting edge with sealing brush in conjunction with described in attached drawing 1-2, including after caisson cutting edge 2, wall after Rock And Soil 5, wall
Mud ditch 3 further includes sealing brush 1, and 5 side of Rock And Soil is step structure, 4 or more open caisson sword of step surface after 2 Lin Bi of caisson cutting edge
It after 5 side of Rock And Soil and wall between Rock And Soil 5 is mud ditch 3 after wall after 2 Lin Bi of foot, in 4 or less caisson cutting edge of step surface, 2 Lin Bi
It is equipped with sealing brush 1 after 5 side of Rock And Soil and wall between Rock And Soil 5 afterwards, sealing brush 1 includes brush teeth and fixed bottom plate 9, fixed bottom plate
9 one sides are connect with 5 side of Rock And Soil after 2 Lin Bi of caisson cutting edge, are equipped at intervals with several brush teeths on the another side of fixed bottom plate 9,
Brush teeth includes several bristles 7, bristle intermediate plate 8, and 7 one end of bristle is gripped by bristle intermediate plate 8, and bristle intermediate plate 8 is fixed on fixation
On bottom plate 9, bristle 7 exposes outside bristle intermediate plate 8 far from one end of bristle intermediate plate 8, exposes the bristle 7 other than bristle intermediate plate 8
With certain flexibility.
A kind of caisson cutting edge with sealing brush, 5 side of Rock And Soil after 2 step surface of caisson cutting edge, 4 or less Lin Bi
On be fitted with pre-buried fixation steel plate 6.
A kind of caisson cutting edge with sealing brush, fixed bottom plate 9 are welded on pre-buried fixation steel plate 6 or pass through fixation
Bolt is fixed on pre-buried fixation steel plate 6, and sealing brush 1 passes through fixed bottom plate 9 and is fixed on the pre-embedded steel slab 6 of caisson cutting edge 2.
A kind of caisson cutting edge with sealing brush, bristle 7 and bristle intermediate plate 8 are made of metal material.
When implementing the present invention: first gripping several 7 one end of bristle by bristle intermediate plate 8, bristle intermediate plate 8 is fixed on fixation
On bottom plate 9, bristle 7 exposes outside bristle intermediate plate 8 far from one end of bristle intermediate plate 8, and sealing brush 1 passes through fixed bottom plate 9 and is fixed on
On the pre-embedded steel slab 6 of caisson cutting edge 2, in open caisson construction, during caisson cutting edge 2 declines, infused in mud ditch 3 after wall
Enter MUD LUBRICANTS, the frictional resistance after sealing brush 1 and wall between Rock And Soil 5 is smaller, will not make to well sinking in open caisson construction
At influence, the caisson cutting edge provided with sealing brush 1 has thoroughly blocked mud ditch 3 and the connection in well after wall, effectively prevents wall
Mud flows into well afterwards, needs to fill the water not intercommunication inside and outside borehole wall when carrying out mud circulation deslagging shaft sinking in well, avoid because
Intercommunication, which causes the interior outside slurry liquid face height of the borehole wall to change, inside and outside the borehole wall influences construction or retaining wall effect.
Part not in the detailed description of the invention is the prior art.
The embodiment selected herein to disclose goal of the invention of the invention, is presently considered to be suitable, still,
It is to be understood that the present invention is intended to include all changes and improvement that all belong to the embodiment in this design and invention scope.
