Description
Technical field
The utility model belongs to the Construction of Civil Engineering technical field, is specifically related to a kind of square jet formula perforating device.
Background technology
Civil engineerings such as water conservancy, building, highway are carried out the engineering construction of pile sinking or pile pulling through regular meeting, and this engineering construction all will use perforating device.During operation, under the effect of lifting force, perforating device is sling, and does the movement of falling object then, in moving downward process, reaches the purpose of pore-forming.At present, the perforating device that is used for pile sinking or pile pulling engineering construction generally is divided into hydraulic, hydrostatic profile and oscillating mode, the perforating device of these types generally all is to design at the pile foundation of cross section for circle, use this circular perforating device also can use when the pore-creating for side stake, but use very inconvenient, dismounting is loaded down with trivial details, be easy to damage, inefficiency, the Kong Yufang stake of producing does not match and strengthen construction costs, and exist at certain geological conditions, the form of structure of stake or the weak point on the size.
The utility model content
The utility model is in order to solve weak point of the prior art, provide a kind of simple in structure, be easy to dismounting, with low cost, pore-forming efficiency is high, be specially adapted to the sink square jet formula perforating device of the side of a pulling out engineering of multiple geological conditions.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: square jet formula perforating device, comprise the perforating device body, the perforating device body is provided with suspension ring and water inlet pipe, perforating device body lower end is provided with the pore-forming blade, water inlet pipe is provided with shower nozzle, and the endoporus cross section of described perforating device body is a square structure.
A side in the middle of four sides of described perforating device body offers breach at vertical direction, and this notch length is consistent with the perforating device body height, and width is consistent with the interior square hole width of perforating device body.
Described perforating device body is that square interior body and outer body formed by cross section, and water inlet pipe is provided with two, two water inlet pipes vertically and symmetry be located in the cavity of body and outer body formation.
Described two equal levels in water inlet pipe lower end are provided with a jet pipe, and shower nozzle vertically is located at the jet pipe bottom.
Vertically be provided with drinking-water pipe in the cavity that body and outer body form in described.
Adopt said structure, the endoporus cross section of perforating device body is a square structure, and the pile sinking or the pile pulling of its side of being, pile foundation hole that produces stake are used, and specific aim is stronger, operating efficiency is higher; On the perforating device body breach is set, has both considered the situation of inclined degree between stake and the stake, also consider at the pore-forming blade rapidlyer during at the shearing soil layer, reduced manufactured materials and reduced cost, improved the operating efficiency of pore-forming; Water inlet pipe is provided with two and be symmetrical arranged, and can keep the gravity balance of perforating device body; When operation, the shower nozzle on the jet pipe is mapped to bottom cutting soil layer with high pressure water jets, destroys soil layer construction, water and soil mixes in slotted eye, because constantly feedwater constantly destroys soil layer, alleviate the friction of pore-forming blade and soil layer, avoid the quick damage of pore-forming blade, improved speed of fulfiling hole; Drinking-water pipe is used for mud is extracted into ground, avoids being full of mud in the hole and the work that has influence on perforating device; The utility model is reasonable in design, simple in structure, with low cost, durable, long service life, pore-forming efficiency height, is applicable to multiple geological conditions, and the stake hole of plastic various ways, multiple size especially is fit to the pile sinking or the pile pulling engineering of side's stake.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the left view of Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, square jet formula perforating device of the present utility model, comprise perforating device body 1, perforating device body 1 lower end is provided with pore-forming blade 9, endoporus 5 cross sections of perforating device body 1 are square structure, a side in the middle of 1 four sides of perforating device body offers breach 10 at vertical direction, and these breach 10 length are highly consistent with perforating device body 1, and width is consistent with endoporus 5 width of perforating device body 1.Perforating device body 1 is that square interior body 3 and outer body 4 formed by cross section, outer body 4 bilateral symmetry are provided with two suspension ring 2, symmetry and vertically be provided with water inlet pipe 7 and water inlet pipe 8 in the cavity 6 that interior body 3 and outer body 4 form, water inlet pipe 7 and water inlet pipe 8 lower ends level respectively are provided with jet pipe 11 and jet pipe 12, jet pipe 11 and jet pipe 12 bottoms evenly vertically are provided with several shower nozzles 13, also vertically are provided with drinking-water pipe 14 in the cavity 6 that interior body 3 and outer body 4 form.
When work is used, earlier water inlet pipe 7 is connected with ground water system (pressure flow of 0.35～0.5Mpa is provided) with water inlet pipe 8, suspension ring 2 are connected with lifting means (hoist engine of crane or band frame) by wire rope, are needing about 0.5 meter dark groove of excavation on the ground of pore-forming then.During the pile sinking pore-forming, open several shower nozzles 13 on jet pipe 11 and the jet pipe 12, lifting means is mentioned certain altitude with perforating device body 1, appoint 1 free-falling of perforating device body, gravitional force is converted into impact force, pore-forming blade 9 is energetically to the down cut soil layer, shower nozzle 13 is sprayed water straight down simultaneously, when hydraulic pressure during greater than the anti-shearing force of soil layer, the water destruct that soil layer is then sprayed by shower nozzle 10, the mud that forms can be used by the reservoir post precipitation that drinking-water pipe 14 is extracted into ground again, and perforating device body 1 ceaselessly moves up and down like this, reaches into the purpose of square hole.
