Abstract

This application involves the MJS stake machines that one kind can prevent spoil disposal suction inlet from blocking, including stake owner's body, it is characterized by: the stake owner body includes a vertically disposed column, column bottom end is equipped with mud nozzle, inserted with dredging tube on column, dredging tube is connected with mud pit, dredging tube bottom end has mud suction mouth, the bottom end of the column is equipped with a high pressure water spray nozzle at mud suction mouth position, high pressure water spray nozzle sprays high pressure water, mud density around mud suction mouth is diluted by the effect of high pressure water or breaks up big soil block, and spoil disposal is made to reach optimum efficiency.

Description

A kind of MJS stake machine for preventing spoil disposal suction inlet from blocking

Technical field

The utility model relates to a kind of MJS machines, are especially a kind of MJS stake machine that can prevent spoil disposal suction inlet from blocking.

Background technique

MJS Construction Technology of Jet Grouting Piles, since it can solve conventional high-pressure rotary churning pile, cement mixing pile, SMW engineering method stake Deng generating biggish extrusion stress to periphery, land upheaval, earth surface cracks etc. can be led to the problem of, and having can be comprehensive Slip casting, pile quality is good, expanded diameter is big, surrounding enviroment are influenced with small, mud contamination is few, occupied ground is small, and it is excellent that headroom is low etc. Point, main application type includes that shield export & import is reinforced, soil stabilization, water-stop curtain, protection are tight in foundation pit enclosure and hole at present Important construction of structures (subway during such as ancient building, operation), the underground space structure construction of neighbour.At present in Shanghai, Zhejiang It is more Deng area application.

Although the more conventional engineering method of MJS has greater advantage, in the actual construction process, there is one for MJS machines itself Larger defect: spoil disposal suction inlet easily blocks.Spoil disposal suction inlet is easy to be blocked by biggish soil block, also holds sometimes due to mud density is larger It easily causes mud suction mouth to block, causes spoil disposal unsmooth, influence construction quality and construction speed.

Utility model content

In view of the defect of the above-mentioned prior art, the purpose of this utility model is that: providing one kind can prevent spoil disposal suction inlet stifled The MJS stake machine of plug.

The technical solution of the utility model is: the MJS stake machine that one kind can prevent spoil disposal suction inlet from blocking, including stake owner Body, the stake owner body include a vertically disposed column, and column bottom end is equipped with mud nozzle, inserted with dredging tube on column, Dredging tube is connected with mud pit, and dredging tube bottom end has mud suction mouth, and the bottom end of the column is equipped with one at mud suction mouth position High pressure water spray nozzle.

Further, the bottom end of the column is equipped with pressure sensor.

Further, dredging tube connects dredge pump, and dredge pump is arranged in mud pit.

Further, high pressure water spray nozzle connects water pipe, and water pipe leads to tap water.

Further, the pile area that mud nozzle passes through pipe conveying mud to underground.

Using the MJS stake machine that one kind provided by the utility model can prevent spoil disposal suction inlet from blocking, the beneficial effect is that: it is high It presses water jet to spray high pressure water, mud density around mud suction mouth is diluted by the effect of high pressure water or breaks up big soil block, make to arrange Mud reaches optimum efficiency.

Detailed description of the invention

Fig. 1 is the overall structure diagram of the utility model.

It is as shown in the figure: A-stake owner's body, B-pile area, 1-column, 2-mud nozzles, 3-dredging tubes, 4-mud Pond, 5-mud suction mouths, 6-high pressure water spray nozzles, 7-control hosts, 8-pressure sensors.

Specific embodiment

For it is relatively intuitive, be fully understood by the technical solution of the utility model, now just combine the progress of the utility model attached drawing Unrestricted feature description is as follows:

As shown in Figure 1, a kind of MJS stake machine that can prevent spoil disposal suction inlet from blocking, including stake machine main body A, stake machine main body A include One vertically disposed column 1,1 bottom end of column are equipped with mud nozzle 2, and inserted with dredging tube 3 on column 1, dredging tube 3 is connected with mud Stock tank 4,3 bottom end of dredging tube have mud suction mouth 5, and the bottom end of column 1 is equipped with a high pressure water spray nozzle 6 at 5 position of mud suction mouth.

Dredging tube 3 connects dredge pump (not shown), and dredge pump is arranged in mud pit 4.High pressure water spray nozzle 6 connects water Pipe, water pipe lead to tap water.The pile area B that mud nozzle 2 passes through pipe conveying mud to underground.

Stake machine main body A further includes the control host 7 resting on the ground, and control host 7 controls dredge pump and inhales mud, and also control is high It presses water jet 6 to spray water, also controls mud nozzle 2 and spray mud.The bottom end of column 1 is equipped with pressure sensor 8, as the pile area B of underground After mud is more can pressure increase, the pressure of underground also will increase when mud row does not go out, pressure sensor 8 will at this time The pressure data measured passes to control host 7, and control host 7 controls dredge pump and inhales mud, can prevent from causing because pressure is excessive The case where land upheaval, occurs.

The MJS stake machine that one kind provided by the utility model can prevent spoil disposal suction inlet from blocking, high pressure water spray nozzle 6 spray high pressure Water dilutes 5 surrounding mud density of mud suction mouth by the effect of high pressure water or breaks up big soil block, spoil disposal is made to reach optimum efficiency.

Certainly, the above is only the preferred embodiments of the present utility model only, and therefore, it does not limit the patents of the utility model Range, all with the utility model specification and schema content institute, simply modification and equivalent structure change for it, should all similarly wrap Within scope of patent protection contained in the utility model.

Claims

1. the MJS stake machine that one kind can prevent spoil disposal suction inlet from blocking, including stake owner's body, it is characterised in that: the stake owner body packet Include a vertically disposed column, column bottom end is equipped with mud nozzle, and inserted with dredging tube on column, dredging tube is connected with mud Pond, dredging tube bottom end have mud suction mouth, and the bottom end of the column is equipped with a high pressure water spray nozzle at mud suction mouth position.
