Description

A kind of slip casting under water of cement-based material or mud jacking block ground mass foundation construction
Technical field
The invention belongs to hydraulic engineering cement sill underwater foundation construction method.
Background technology
Many hydraulic engineerings are because be difficult to draining, and engineering has to stop work.For example in recent years, weather anomaly arid, reservoir Retaining is more difficult, is often all difficult to retaining to autumn reservoir.Construction, shadow but Reservoir progress dam bank protection must discharge water The retaining to reservoir is rung, peasant opposes very much, often do expediently peasant colony and hinder construction, because discharging water to have influence on down 1 year kind.For example, carrying out reservoir dam slope protection construction, basic pin groove excavation is deeper, because peasant's shield water is difficult to be constructed.Such as Fruit can have a kind of method to realize the underwater construction technology for not discharging water or discharging water less as far as possible, then, it is possible to effectively solve this Class protects water and the contradiction of construction, reservoir is ensured retaining conscientiously, moreover it is possible to complete the reinforcement of dam.On the other hand, In northeast, autumn water temperature is relatively low, into October, and coolant-temperature gage is 7~8 or so, and underwater concrete, which condenses, to be affected.
The content of the invention
The present invention provides a kind of cement-based material slip casting under water or mud jacking block ground mass foundation construction, complete under water to realize Into cement base basis or filling class formation, for hydraulic engineering, it can be ensured that hydraulic engineering cement sill structure under water can be carried out Construction, so that reduction temporary project and effluent cost is greatly reduced, greatly improves construction speed, compared with underwater concrete construction Construction costs can be greatly reduced, is constructed for cement base class formation under reservoir water, it can be ensured that discharge water less, many retainings, it is ensured that Next year irrigation water.Quickly handle because osmotic pressure leak forms hole or rapid reinforcement submerged structure, can significantly carry for reservoir High project progress, it is ensured that problem engineering is handled in time, it is ensured that engineering safety.
The present invention is adopted the technical scheme that, is comprised the following steps:
(One)Utilize hook machine excavation foundation groove, 2.5 ~ 3.5 meters of single operation length;
(Two)According to the situation of foundation trench, selection cement-based material under water apply by slip casting method or mud jacking block stone method progress basis Work:
(1)When dug foundation trench is located under the water surface, using closed structure sizing cage, selection cement-based material is under water Slip casting method carries out foundation construction:
The closed structure sizing cage can make under water, can also by land make and be then placed in water, by steel Muscle, GSZ or batten work out gabion with steel wire, to prevent running pulp, gabion external application non-woven wraps or liner non-woven fabrics, nothing The effect for spinning cloth is the water discharged in gabion and prevents that binder materials leaks in gabion, inserts grout pipe in gabion, makes this Grout pipe is located on the water surface, is filled up with block stone after gabion, suitable for reading to be closed with non-woven fabrics and gabion top flat;
Slip casting:Slurry is injected with grouting pump low pressure, the slurry is the higher sand coarse aggregate ratio chicken girt concrete of low leaching cement base, institute Stating the higher sand coarse aggregate ratio chicken girt concrete of low leaching cement base includes the raw material of following parts by weight:
