Problems solved by technology

However, this method has the following problems: 1. When using this equipment, it is still necessary to dig a clear water pool in advance and make a cement pool. The workload in the early stage is huge and the production efficiency is low; Falling, causing serious pollution to crops, fish ponds, shrimp ponds, etc. around the air
2. If the cement pool is not used up at one time, it will cause a lot of waste
3. This method still cannot overcome the phenomenon of "reverse slurry"
4. It is not suitable for powder spraying single and two-way mixing pile machines

Embodiment 1

[0041] Such as figure 1 As shown, this embodiment provides a cement mixing pile construction system, including a cement mixing pile machine 5 and a cement conveying device.

[0042]The cement mixing pile driver 5 includes an inner drill rod 501 and an outer drill rod 502 nested with each other. The inner drill rod 501 is hollow inside, and the upper end is provided with a first sealing collar 503 for connecting the powder delivery pipe 607 . The outer drill pipe 502 is sleeved on the outer ring of the inner drill pipe 501 , and the end of the outer drill pipe 502 is provided with a second sealing collar 504 for connecting the slurry delivery pipe 606 . Bottoms of the inner drill rod 501 and the outer drill rod 502 are provided with spray ports and rotating blades. A dry humidity sensor 505 is also installed at the lower end of the outer drill rod 502 .

[0043] The cement delivery device includes a cement storage module 1 , a cement upper feeding module 2 , a liquid pump mo...

Embodiment 2

[0064] Such as image 3 As shown, the basic structure of this embodiment is the same as that of Embodiment 1, and the difference lies in:

[0065] The water outlet connection pipe 605 and the slurry delivery pipe 606 are connected through the third connection pipe 603 and the water delivery control valve 218 . The intake connecting pipe 604 is also connected to the powder delivery power unit 203 through the intake control valve 219 . A flow controller 216 is added on the slurry delivery pipe 606 .

[0066] In the construction process of this embodiment, the powder feeding power unit 203 not only controls the powder feeding through the conversion control valve 204 and the powder feeding control valve 209, but also opens the intake control valve 219 during the powder feeding process to increase the powder feeding power The pressure in the unit 203 increases the efficiency of the powder conveying power unit 203 for conveying cement powder to the powder conveying pipe 607 . Aft...

Embodiment 3

[0069] Such as Figure 4 As shown, the basic structure of this embodiment is the same as that of Embodiment 1, and the difference lies in:

[0070] The cement storage module 1 includes a storage tank 102 and a bagged cement feed tank 103 . The lower end of the storage tank 102 has a tapered structure, and is connected to the first connecting pipe 601 and the second connecting pipe 602 in the same manner as the bulk cement storage tank 101 in the first embodiment. The bagged cement feed tank 103 is connected to the storage tank 102 through a transfer pipe 104, and the transfer pipe 104 is provided with a feeding control valve 105. The air pump module 4 is connected to the upper end of the bagged cement feeding tank 103 by the air inlet connecting pipe 604, and in the air inlet connecting pipe 604, the connecting pipe part connecting the bagged cement feeding tank 103 is provided with a pressure control valve 106, and the storage Tank 102 is a container provided with a vent fi...

Abstract

The invention relates to an environment-friendly cement feeding and conveying device and a cement mixing pile construction system. The cement feeding and conveying device comprises a cement storage module, a cement feeding and conveying module, a liquid pump module and an air pump module, wherein the cement feeding and conveying module comprises a high-speed stirrer, a slurry conveying power unitand a powder conveying power unit; the high-speed stirrer is connected with the slurry conveying power unit through a slurry inlet control valve; the slurry conveying power unit is connected with a slurry conveying pipe; the powder conveying power unit is connected with a powder conveying pipe; the slurry conveying power unit and the powder conveying power unit are connected with a conversion control valve; the cement storage module is connected with the high-speed stirrer and the powder conveying power unit; the air pump module is connected with the conversion control valve and a pulse control valve; the other end of the pulse control valve is connected with the cement storage module; and the liquid pump module is connected with the high-speed stirrer. Compared with the prior art, powderspraying and slurry spraying operation can be alternately implemented in the pile forming process, and the pile forming quality is remarkably improved; and meanwhile, the environment-friendly cement feeding and conveying device has multiple purposes, the application range is wide, and the practical value is high.

Description

technical field [0001] The invention relates to the construction field of cement mixing piles, in particular to an environment-friendly cement feeding device and a cement mixing pile construction system. Background technique [0002] Cement mixing pile is an effective form of soft foundation treatment. It uses cement as the main agent of curing agent, sprays cement into the soil and mixes it fully, so that a series of physical and chemical reactions between the cement and the soil will occur, and the soft soil will harden. To increase the strength of the foundation. Existing cement mixing piles generally include powder-sprayed single- and two-way mixing pile drivers and slurry-sprayed single- and two-way mixing pile drivers. Among them, the pile body formed by the powder-sprayed single-way mixing pile machine is scattered due to insufficient water in the upper part, and the cement powder in the drill pipe will rise up along the drill pipe, and the phenomenon of "reverse ash...
