Description

A kind of dredging from steel pipe pile inside got the device of mud

Technical field

The utility model relates to a kind of dredging and gets mud dress, in particular, the utility model relate to a kind of be applicable to dredge from steel pipe pile inside get the device of mud.

Background technology

Along with the fast development of ocean engineering, the structure waterborne that match with it are also because the lifting of its ability need change, extends and remove; In addition, cause influence for the structure of avoiding some to produce not needed or finish using waterborne take navigation channel or waters after discarded, also need these water obstacles and insert steel pipe pile in the ground etc. deeply and remove boats and ships such as water transportation transportations.

Traditional method for dismounting is to adopt earlier construction equipment such as dredge boat mud and soil to be removed around it, and then carries out the cutting of steel pipe pile from the outside and pull out.But there is following defective in this method:

(1), and dredges and also can cause pollution the marine site because construction equipment such as dredge boat can not directly arrive between the steel pipe pile, and it is a lot of that difficulty that earth removes and engineering quantity are increased.

(2) mud around the steel pipe pile also can back-silt fast and cause difficulty, the expense of steel pipe pile dismounting because of the influence of factors such as morning and evening tides, thereby the duration is increased.

The utility model content

The purpose of this utility model, just provide a kind of dredging and get the device of mud from steel pipe pile inside, solve using that the present existing outside of the steel pipe pile method for dismounting amount of dredging is big, the work period is long, expense is high and to cause problem such as environment pollution, thereby conveniently finish the last work of pulling out by the cutting of inner steel pipe pile.

In order to realize above purpose, the utility model adopts following technical scheme:

A kind of dredging from steel pipe pile inside got the device of mud, comprise dispenser, described dispenser is for connecting as one and two separation structures of boring by lapping plate, the one end connects the movable sealing hyoplastron by hinge, the rear and front end of its side is respectively arranged with guide strip and guide ring, its front portion is set to conduit, the front end of conduit is provided with cone, its center of gravity position is provided with the lifting hanger, the left and right sides of described lifting hanger is provided with the first haulage cable directive wheel and the second wire rope directive wheel respectively, described first, also be provided with the tensioned bearing that gathering sill and telescopic spring slide plate are installed in it on the dispenser of the second wire rope directive wheel offside, end from described movable sealing hyoplastron crosses described first, the second wire rope directive wheel is provided with the traction seal wire rope, crosses the hinged hinge of itself and described dispenser to the telescopic spring slide plate in the described tensioned bearing from the other end of described movable sealing hyoplastron and is provided with haulage cable.

The utility model adds the suspender that is provided with hanger in use.

The utility model is compared with existing silt dredging device, and its beneficial effect is:

(1) can transfer and insert in the earth of steel pipe pile by crane and vibrating hammer, not only can take out the earth in the straight shaped steel pile tube, also can take out the earth in the taper pile, so, make things convenient for construction equipments such as dredge boat can not directly arrive the interior field working conditions of steel pipe pile, thereby reduced difficulty and the engineering quantity that earth is removed.

(2) earth in the dispenser can be opened movable sealing hyoplastron wherein voluntarily under the deadweight and the control of mechanical mechanism for opening/closing, is placed on assigned address thereby the earth that takes out unloaded, and has avoided mud diging working to cause the possibility of maritime environment pollution.

(3) rational in infrastructure, easy to operate, solved and used present big, the problems such as the work period is long, expense is high, easy contaminated environment of the existing outside of the steel pipe pile method for dismounting amount of dredging, finished the last work of pulling out for the cutting of steel pipe pile internally and created advantage.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done to describe in detail.

As Fig. 1, Fig. 1-1, Fig. 1-2, Fig. 2, Fig. 3, shown in Figure 4, the utility model is dredged from steel pipe pile inside and is got the device of mud, comprise dispenser 3, described dispenser 3 for connect as one by lapping plate 5 and boring two separation structures, so the lap-joint of described two separation structures leaves the slit that enters and leave in its inner space with earth.One end of described dispenser 3 connects movable sealing hyoplastron 1 by hinge, the rear and front end of its side is respectively arranged with guide strip 2 and guide ring 10, the front central of described dispenser 3 is a conduit 11, the front end of described conduit 11 is provided with cone 13, the center of gravity position of described dispenser 3 is provided with lifting hanger 8, the left and right sides of described lifting hanger 8 is respectively arranged with the first haulage cable directive wheel 6 and the second wire rope directive wheel 9, on the dispenser 3 of described first haulage cable directive wheel 6 and the second wire rope directive wheel, 9 offsides, also be provided with tensioned bearing 17, described tensioned bearing 17 is by bearing and be arranged on the gathering sill 15 in the bearing and the telescopic spring slide plate 16 that is installed in the gathering sill 15 is formed, cross the described first haulage cable directive wheel 6 and the second wire rope directive wheel 9 is provided with traction seal wire rope 4 from an end of described movable sealing hyoplastron 1, cross itself and described dispenser 3 hinged hinge to the telescopic spring slide plates 16 in the described tensioned bearing 17 from the other end of described movable sealing hyoplastron 1 and be provided with haulage cable 7.The utility model in use, also additional have a suspender 14, described suspender 14 can be mounted on the auxiliary hook of turned crane by the hanger 12 of setting it on.

The course of work of the present utility model is such:
