Abstract
The utility model relates to the improvement of a wall-building machine using a water-jetting method to build underground continuous anti-seepage walls, comprising a hole building machine, a concrete casting machine and a concrete stirring machine, and meanwhile, the utility model is added with a slag discharging machine. The center of the lower part of a former is provided with a slag sucking pipe which is connected with the slag discharging machine. Water and slag mixture is continually sucked out by the slag discharging machine through the slag sucking pipe to form an integrally underground thin groove hole, and then underground concrete is cast. Compared with the original wall-building machine using the water-jetting method, the utility model has wide application for stratums and geologies and can build the anti-seepage walls in rubble and gravel soil whose grain diameter is less than 80 mm, the effective anti-seepage thickness of the utility model reaches 100%, and meanwhile, the utility model has simple construction and fast speed and has the actions of reducing the labor intensity and raising the work efficiency.
Description
The utility model belongs to engineering construction field of mechanical technique such as water conservancy, civil engineering, relates to a kind of wall telephone of making that is used to build underground concrete, specifically a kind of improvement of water injection process for building wall machine.
Existing domestic and international impervious wall to the dyke seepage control project generally adopts Churn drill, dashes the methods such as awl, sheet pile, perfusion of grabbing, the shortcoming that these facility ubiquity speed are slow, construction is complicated, cost is high.Fujian Inst. of Water Conservancy and Hydroelectric Sciences is through long-term scientific research and development, succeeded in developing " water jetting is built underground concrete continuous impervious wall technology " in 1986, and declare " water injection process for building wall machine " patent to Patent Office of the People's Republic of China, in 1992 power of patenting (patent No. ZL89213927.7).But, this adopts the direct circulation method of slagging tap because making wall telephone, promptly the soil layer formation water and soil mixture by water under high pressure and former destruction overflows, so this machine only is applicable to stratum such as closely knit clay, lam, mud, sand and medium coarse sand, be not suitable for the levee foundation absorbent formation that contains big particle diameter cobble, gravel, therefore its suitable geological conditions is narrow, and the scope of application is limited.
The purpose of this utility model is to be suitable for the problem that geological conditions is narrow, the scope of application is limited and the water injection process for building wall machine that provides a kind of anti-circulation to slag tap at existing water injection process for building wall machine.It is applicable to building the underground concrete continuous impervious wall of thin-walled (more than the 22cm) in the various geo-logical terrain structures that contain cobble, gravel below the 80mm.
The main mechanical of water injection process for building wall machine includes borer, concrete casting machine, concrete mixer etc., and shaping device is installed on the borer, makes freely falling body after being mentioned by hoist engine, pounds into ground damage layer soil property.The strong stream of going out by the water-blaster on the shaping device impacts soil layer, destroys its structure, and ground is overflowed in the water and soil mixing, so constantly move at thin-walled slotted eye of underground formation, and then by concrete casting machine perfusion concrete, thus the formation underground impervious wall.
The anti-circulation water injection process for building wall machine of slagging tap is to improve to form on the basis of original water injection process for building wall machine, it also includes borer, concrete casting machine, concrete mixer, shaping device is installed on the borer, increase a slag extractor simultaneously, the centre of shaping device bottom is equipped with dreg inhaling pipe, and this dreg inhaling pipe links to each other with described slag extractor.After ruined like this soil layer and water under high pressure form the grain slag mixture, by the continuous sucking-off of dreg inhaling pipe, by shaping device edge of a knife finishing border, can form a complete underground thin slotted eye, and then build underground concrete again by slag extractor.
Characteristics of the present utility model are to use jetting pore-creating, slag tap and the slurry strengthened wall pore-forming with anti-circulation in thin-walled (more than the 22cm) slotted eye.Owing on original basis of making wall telephone, increased slag extractor and dreg inhaling pipe, can the following cobble of sucking-off diameter 80mm, the slag that mixes of gravel and water, therefore this machine is compared with original water injection process for building wall machine, and it is wide to adapt to stratum geology scope, and effectively antiseepage thickness reaches 100%.Construction simultaneously is simple, speed is fast, the effect that has reducing labor intensity and improve work efficiency.
Describe structure of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the slag tap structural representation of water injection process for building wall machine of this anti-circulation.
Fig. 2 is the structure sectional view of shaping device.
Fig. 3 is the lateral view of shaping device.

As shown in Figure 1, borer 201, concrete casting machine 202, concrete mixer 203 places on the same walking track with slag extractor 204, and the press water of being supplied with by water pump arrives shaping device 205 on the borer by hydraulic pipeline, forms the water jets under high pressure jet and destroys earth formation.Water and soil mixes in slotted eye.The water and soil mixed liquor by slag extractor by the dreg inhaling pipe sucking-off on the shaping device.Shaping device pumps under hoist engine is handled, and further destroys the stratum and repairs hole wall, and drilling depth gradually causes the rectangle slotted eye of specification.Subsequent by concrete casting machine and concrete mixer carry out straight pipe type under water concrete build.Owing to adopt two preface methods constructions, make 1# earlier, 3#, the single sequence number concrete of 5#...... frid after concrete initial set in one to two day hole, reproduces 2#, 4#, the two sequence number concrete frids of 6#.......Single, double thus sequence number concrete frid links into an integrated entity securely, forms underground concrete continuous impervious wall.
