Abstract
The invention discloses a concrete grouting construction method and a device for implementing the same. The device comprise a plurality of tremies of which one ends extend into underwater concrete in a grouting slot; a blanking hopper is arranged at the top end of each tremie; a slag pumping pipe is arranged in the grouting slot; and the bottom end of the slag pumping pipe is positioned at a position which is 1-2 meters away from the surface of the underwater concrete. According to the concrete grouting construction method and the construction device, slurry above the surface of the underwater concrete is pumped through the slag pumping pipe in a concrete pouring process, and concrete is poured in the pumping process, so that the quality of underwater concrete is prevented from being damaged by the slurry above the surface of the underwater concrete, and the piling quality of the underwater concrete is effectively ensured; and the method and the device can be applied to the field of building construction.
Description
Technical field
The present invention relates to the realm of building construction, particularly relate to the device of a kind of filling concrete construction method and enforcement the method.
Background technology
After general construction pile body or diaphragm wall pore-forming, start pouring underwater concrete through clear hole, in this filling process, only removed conduit and controlled pipe laying depth, and mud has not been carried out to circular treatment, easily cause the pile defect after pile.
Summary of the invention
For addressing the above problem, the invention provides a kind of can effective guarantee pile quality filling concrete construction method and implement the device of the method.
The technical solution adopted for the present invention to solve the technical problems is:
Filling concrete construction method, is characterized in that, comprises the following steps:
1), in filling concrete slotted eye, pour into a mould one section of underwater concrete;
2), detect the hyperscaling of described underwater concrete raised floor mud index;
3), extract the body refuse apart from underwater concrete face 1～2m place by dreg-drawing pipe, mend slurry simultaneously, then continue to build underwater concrete;
4), promote dreg-drawing pipe, make dreg-drawing pipe be positioned at gradually on the underwater concrete surface of rising 1～2m place until concreting is complete always.
Be further used as the improvement of technical solution of the present invention, the mud amount extracting by dreg-drawing pipe in step 3) equates with benefit slurry amount.
Being further used as the improvement of technical solution of the present invention, step 2) front underwater concrete height of having built is 10m～20m.
Implement the filling concrete construction equipment of said method, comprise that in perfusion slotted eye, the some tremies in underwater concrete are stretched in one end, the top of each tremie is equipped with lower funnel, in perfusion slotted eye, be also provided with dreg-drawing pipe, the bottom of dreg-drawing pipe is positioned at the position of 1～2m on underwater concrete surface.
Be further used as the improvement of technical solution of the present invention, in perfusion slotted eye, be also provided with and mend slurry pipe, the grout outlet of mending slurry pipe is positioned under slurry face.
Beneficial effect of the present invention: this filling concrete construction method and construction equipment are carrying out in concreting process, by dreg-drawing pipe, mud more than underwater concrete surface is extracted, and carry out concrete cast in the process extracting, can prevent the quality of the mud infringement underwater concrete of underwater concrete face top, thus the pile quality of effective guarantee underwater concrete.
Brief description of the drawings
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is embodiment of the present invention overall structure schematic diagram.
Detailed description of the invention
With reference to Fig. 1, the present invention is a kind of filling concrete construction method, it is characterized in that, comprises the following steps:
1), in filling concrete slotted eye, pour into a mould one section of underwater concrete;
2), detect the hyperscaling of described underwater concrete raised floor mud index;
3), extract the body refuse apart from underwater concrete face 1～2m place by dreg-drawing pipe, mend slurry simultaneously, then continue to build underwater concrete;
4), promote dreg-drawing pipe, make dreg-drawing pipe be positioned at gradually on the underwater concrete surface of rising 1～2m place until concreting is complete always.
Implement the filling concrete construction equipment of said method, comprise that in perfusion slotted eye, the some tremies 1 in underwater concrete are stretched in one end, the top of each tremie 1 is equipped with lower funnel 2, in perfusion slotted eye, be also provided with dreg-drawing pipe 3, the bottom of dreg-drawing pipe 3 is positioned at the position of 1～2m on underwater concrete surface.
This filling concrete construction method and construction equipment are carrying out in concreting process, by dreg-drawing pipe 3, mud more than underwater concrete surface is extracted, and carry out concrete cast by tremie 1 in the process extracting, can prevent the quality of the mud infringement underwater concrete of underwater concrete face top, thus the pile quality of effective guarantee underwater concrete.
As the preferred embodiment of the present invention, the mud amount extracting by dreg-drawing pipe in step 3) equates with benefit slurry amount.
As the preferred embodiment of the present invention, step 2) front underwater concrete height of having built is 10m～20m.
As the preferred embodiment of the present invention, when underwater concrete difference in height 10m that underwater concrete identity distance is built from needs, stop step 4).
As the preferred embodiment of the present invention, in perfusion slotted eye, be also provided with and mend slurry pipe 4, the grout outlet of mending slurry pipe 4 is positioned under slurry face.
Mend slurry pipe 4 and in work progress, constantly supplement solidifying slurry, so that perfusion slotted eye is carried out to retaining wall, prevent from pouring into slotted eye and cave in, ensure construction safety.
For super deeply, in the drilled pile or construction of diaphragm wall process that dark or geological conditions is poor, along with the continuous uphill process of pouring underwater concrete slurry face, in perfusion slotted eye with several meters, underwater concrete raised floor place within the scope of mud index can produce obvious variation.The indexs such as the proportion of mud, sand factor, viscosity have larger variation can start to build than just time, affect the quality of underwater concrete.In pouring underwater concrete process, by anti-circular treatment mode, the above mud of underwater concrete raised floor is carried out to continuous circular treatment, make the indices of mud substantially meet technological requirement, can effectively ensure underwater concrete construction quality.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and the modification that these are equal to or replacement are all included in the application's claim limited range.
