Abstract
The invention relates to consolidation grouting constructions in the processing of steep base surfaces of hydraulic and hydro-power engineering and other large-volume concrete structures. The method comprises the following steps: previously casting a reinforced concrete plate with a certain thickness on the steep base surface; pre-burying all consolidation grouting conduits in the plate; after theconcrete plate cast previously reaches a certain thickness, drilling holes and grouting so as to finish the consolidation grouting of the base surface at one time; and meanwhile, pre-burying a normaljoint grouting apparatus on the surface of the concrete plate cast previously, and carrying out the joint grouting after finishing the construction of the concrete structure cast afterwards. The method carries out the basic treatment of the base surface and the concrete construction of the structure separately, and the basic treatment of the base surface does not interfere with the concrete construction of the structure, thereby greatly increasing the construction speed, reducing the equipment tie-up, the transportation cost and the cost for clearing and treating the sites used for consolidation grouting and achieving obvious economic benefit.
Description
Technical field
The technology of the present invention relates to the consolidation grouting construction that is used for Hydraulic and Hydro-Power Engineering and other large volume concrete structural steep dip foundation plane based process, is particularly useful for the consolidation grouting construction of the steep dip dam foundation of high dam.
Background technology
Traditional steep dip foundation plane consolidation grouting construction generally needs the branch multilayer, divides a plurality of periods to carry out.Generally be to locate pre-buried conduit, after treating the concreting certain altitude, reaching certain intensity,, carry out the consolidation grouting construction along pre-buried conduit boring in position, foundation plane consolidation grouting hole.After the consolidation grouting acceptance(check), locate pre-buried conduit, concreting, boring, grouting and examination in position, follow-up consolidation grouting hole again, carry out next working cycles.Circulation successively is until finishing the whole consolidation groutings of building foundation plane.This method exists repeatedly grouting, repeatedly equipment turnover, influences the concreting progress.
Summary of the invention
The technical problem that the technology of the present invention will solve is, at the repeatedly grouting of existing foundation plane consolidation grouting method existence, repeatedly equipment turnover, influence the deficiency of concreting progress, provide a kind of and can effectively guarantee construction quality, the job practices of accelerating construction progress.
The solution of the technology of the present invention is, build certain thickness armored concrete slab on steep dip foundation plane surface in advance, pre-buried whole consolidation grouting conduits in the plate, treat that first pouring concrete plate arrives certain intensity after, hole, be in the milk, once finish the consolidation grouting of foundation plane; While is the pre-buried conventional joint grouting facility in pouring concrete plate surface formerly, treats to carry out joint grouting after back pouring concrete structure construction is finished.
For highly bigger building steep dip foundation plane, can adopt segmentation to implement the consolidation grouting that said method is finished whole foundation plane.
The process conditions of consolidation grouting and equipment all adopt disclosed technology of prior art and equipment.
The beneficial effect of the technology of the present invention is, by building armored concrete slab earlier, once finish the consolidation grouting work of foundation plane, the concreting of having avoided consolidation grouting to cause is slowed down, grouting equipment is repeatedly transferred in, access in the architecture construction field, has reduced the treatment project amount that place after the consolidation grouting repeats to clear up and concrete long intermittently increases.This method can guarantee building concrete evenly construction continuously, and is convenient and simple for operation, practical.Adopt this method that the steep dip foundation plane is carried out consolidation grouting, the construction of foundation plane based process and building concrete separated carry out, the former does not disturb the latter to construct, accelerating construction progress greatly, minimizing equipment accounts for the cleaning and the disposal cost in place behind pressure, freight and the consolidation grouting, and economic benefit is obvious.
Description of drawings
Fig. 1 is the structural representation after the construction of steep dip foundation plane consolidation grouting;
Fig. 2 is that elevation is arranged in adverse grade consolidation grouting hole, embodiment of the invention dam.
Fig. 3 is that sectional drawing is arranged in adverse grade consolidation grouting hole, embodiment of the invention dam
Wherein: 1-waters armored concrete slab earlier; 2-top layer steel mesh reinforcement; 3-bottom layer of the reinforcing steel net; The 4-foundation plane; 5-rock foundation; 6-connects anchor pole; 7-waters pre-buried consolidation grouting hole conduit in the armored concrete slab earlier; 8-consolidation grouting hole; The 9-concrete structure; The 10-prestress anchorage cable; The 11-diversion tunnel that generates electricity.
The specific embodiment
Fig. 1 adopts the inventive method that high steep dip foundation plane is carried out structural representation after the consolidation grouting construction.Behind the foundation plane excavation, directly on one section foundation plane 4, water armored concrete slab 1 earlier.Before building, on rock foundation, insert the connection anchor pole earlier, re-lay bottom layer of the reinforcing steel net and top layer steel mesh reinforcement.Formerly water pre-buried consolidation grouting hole conduit in the armored concrete slab, on rock foundation, beat the consolidation grouting hole, after foundation plane being finished the consolidation grouting construction, water reinforced concrete construction after carrying out.
Fig. 2, Fig. 3 adopt the inventive method certain engineering dam adverse grade to be carried out the working design detail drawing of consolidation grouting.After dam foundation face 4 excavations are finished, in dam adverse grade body 5 internal drillings, insert and connect anchor pole 6, on dam adverse grade body 5, bore consolidation grouting hole 8 simultaneously, the 8 pre-buried consolidation grouting conduits 7 along the consolidation grouting hole on the dam adverse grade body 5, the upright template of watering armored concrete slab 1 earlier of frame again, installing bottom layer steel mesh reinforcement 3, top layer steel mesh reinforcement 2 in the plate, after treating to water earlier armored concrete slab 1 and reaching intensity, dam 9 constructions are carried out in the disposable consolidation grouting work of finishing the dam adverse grade then.
Claims (2)
1. consolidation grouting method of steep base surfaces of marine structures, it is characterized in that, build certain thickness armored concrete slab on steep dip foundation plane surface in advance, pre-buried whole consolidation grouting conduits in the plate, after treating that first pouring concrete plate arrives certain intensity, hole, be in the milk, once finish the consolidation grouting of foundation plane; While is the pre-buried conventional joint grouting facility in pouring concrete plate surface formerly, treats to carry out joint grouting after back pouring concrete structure construction is finished.
2. consolidation grouting method of steep base surfaces of marine structures according to claim 1 is characterized in that for highly bigger building steep dip foundation plane, adopts segmentation to implement the consolidation grouting that the described method of claim 1 is finished whole foundation plane.
