Abstract
The utility model discloses a mixing and sucking type air suction dredge. The mixing and sucking type air suction dredge comprises a dredge head, wherein a high pressure air duct is connected with the upper end of the dredge head; a dredge pipe which penetrates from the top to the bottom is arranged inside the inner cavity of the dredge head; sawteeth are arranged at the lower end of the dredge pipe; power equipment is connected to the outer side surface of the dredge head; the output shaft of the power equipment points downwards vertically and is connected with a power reamer; the power reamer and the sawteeth are on the same horizontal plane. The mixing and sucking type air suction dredge, provided by the utility model, is applicable to dredge operations of overlays of various geology; the overall weight of the suction dredge is reduced; the construction is convenient; the dredge effect is improved.
Description
Technical field
The utility model relates to a kind of suction dredge, refers in particular to a kind of suction airlift suction dredger that stirs.
Background technology
Double-Wall Steel Boxed Cofferdam is applied commonplace in bridge deepwater foundation construction, and its simple structure, construction technology are simple.Conventional Double-Wall Steel Boxed Cofferdam sinking mode in covering layer mostly is suck sediment subsidence, wherein air inhale mud construction because technique is simple, less input, get mud speed fast, be applicable to the advantages such as deep water foundation, in heavy steel cofferdam sinking construction, application is comparatively general.Conventional airlift suction dredger is except power-equipment air compressor machine and gasholder, and main structure is comprised of soil-suction head, dredging tube, high-pressure air hose etc., and this kind of suction dredge is because of less to covering layer disturbance, and suction mud effect is relatively not good; For accelerating to inhale mud speed, conventional method is many carries out water jetting at high pressure in a multistage pump of suction dredge outside installation, a high-pressure water pipe and a high-pressure gun, the method can improve the suction mud efficiency of suction dredge in sandy soils, but cost is relatively high, overall structure is relatively heavy, running into hardening layer, to get mud effect bad.
Utility model content
The purpose of this utility model is to provide a kind of suction airlift suction dredger that stirs, and it is applicable to inhale mud under multiple geological condition covering layer and constructs, and alleviates the whole impedimenta of suction dredge, constructs convenient, inhales mud effect and improves.
To achieve these goals, the utility model provides a kind of suction airlift suction dredger that stirs, comprise soil-suction head, described soil-suction head upper end connects high-pressure air hose, and described soil-suction head inner chamber has placed dredging tube from top to bottom, and described dredging tube lower end is provided with sawtooth, wherein said soil-suction head lateral surface is connected with power-equipment, the output shaft of described power-equipment straight down, and is connected with power reamer, and described power reamer and sawtooth are positioned at same level.
Described power-equipment is light-duty waterproof machine, and described power reamer is connected on the output shaft of light-duty waterproof machine.
Described power reamer is three leaf reamers.
Described power-equipment is bolted or is welded in soil-suction head lateral surface.
Adopt after such scheme, the utility model stirs suction airlift suction dredger by connecting power-equipment at soil-suction head lateral surface, and the output shaft lower end at power-equipment connects reamer, during use, this suction dredge is put into water and pressed close to inhale mud face, start suction dredge and power reamer, in suction dredge work, utilize power reamer to stir the soil body of suction dredge surrounding, it is applicable to inhale mud under multiple geological condition covering layer and constructs, and its construction is convenient, inhales mud effect and improve, and alleviated the whole impedimenta of suction dredge.
Accompanying drawing explanation
Fig. 1 is that the master that the utility model stirs suction airlift suction dredger looks sectional structure schematic diagram;
Fig. 2 is the schematic top plan view that the utility model stirs suction airlift suction dredger.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, so that those skilled in the art can better understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As depicted in figs. 1 and 2, the utility model stirs suction airlift suction dredger, comprise soil-suction head 1, the upper end of soil-suction head 1 is vertically connected with high-pressure air hose 2, and the inner chamber of soil-suction head 1 has vertically placed dredging tube 3 from top to bottom, and dredging tube 3 lower ends are provided with sawtooth 4, the lateral surface of soil-suction head 1 is bolted or is welded with light-duty waterproof machine 5, straight down, and these output shaft 6 lower ends are connected with power reamer 7 output shaft 6 of light-duty waterproof machine 5, and this power reamer 7 adopts three leaf reamers.Power reamer 7 is positioned at same level with sawtooth 4.
During use, the utility model is stirred to suction airlift suction dredger and put into water, soil-suction head 1 presses close to inhale mud face, the power-equipment of the suction dredge that startup is comprised of soil-suction head 1, high-pressure air hose 2 and dredging tube 3 and open light-duty waterproof machine 5, suction dredge and power reamer 7 are worked simultaneously, by power reamer 7, stir Riverbed, make mud suck smoothly dredging tube, thereby improve the operating efficiency of suction dredge.According to delivery port mud content and riverbed depth dose, control the movement of suction dredge, until inhale bricklayer's, complete, inhale mud technical requirements and process control with conventional airlift suction dredger.
The above embodiment is only the preferred embodiment for absolutely proving that the utility model is lifted, and protection domain of the present utility model is not limited to this.Being equal to that those skilled in the art do on the utility model basis substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
