Description

A vibration aid irrigation device

Technical field:

The invention belongs to the perfusion field, and in particular relates to a vibration-assisted perfusion device.

Background technique:

Bridge projects such as highways, railways, and municipal bridges are generally built in my country. Due to the influence of geological conditions, bridges are built in areas with poor geological conditions. In order to meet the requirements of the bearing capacity of the foundation, it is often necessary to design deep pile foundations. In the process of underwater concrete pouring of deep pile foundation, problems such as pipe plugging and concrete not going down due to reasons such as low concrete slump, etc. The reasons for the failure of conventional methods are:

1. The concrete slump is small, the concrete is difficult to flow and disperse at the pipe, and the pipe outlet is piled up, causing the pressure of the pipe mouth to increase, and the concrete in the pipe cannot flow out;

2. Partial siltation of concrete in the pipe makes it difficult for the concrete to block the pipe;

3. When replacing the concrete tank truck, the concrete is poured intermittently and then poured again in a large amount quickly. The air entering after the interruption produces high-pressure air pockets under the action of the concrete falling, making it difficult for the concrete to fall.

Therefore, it is necessary to provide a concrete pouring aid device to overcome the difficulty that the concrete caused by the above reasons is difficult to fall, and to help the concrete pouring smoothly.

Invention content:

The object of the present invention is to provide a vibrating grouting aid device, aiming to solve the problem that the concrete is difficult to fall in the conduit when the deep pile foundation is poured underwater, which makes the concrete pouring of the pile foundation difficult.

The present invention is achieved in this way. The present invention relates to a vibrating irrigation aiding device, which includes a vibrating device, a catheter connector, and a plug-in thread connector; the catheter connector and the vibrating device are detachably connected to the Together, the plug-in threaded connector is at the lower end of the catheter connector, and the threaded button is the same as the catheter threaded button and can be screwed into the catheter to be fixed on the catheter connector, thereby forming an integral body with the vibration device.

Further, the vibrating device is a vibrating hammer.

Further, the conduit connector and the vibrating device are connected to each other using a flange.

Further, the lower end of the plug-in threaded connector is also provided with a limiting device.

A vibrating irrigation aid device provided by the present invention is installed on the top of the conduit when the concrete is difficult to pour and fall. Through the vibration of the vibrating hammer, the concrete at the bottom of the conduit can flow and disperse rapidly under the action of vibration, reducing the concrete pressure at the nozzle. Simultaneously, the coagulation accumulated in the pipe is scattered and scattered. When there is a high-pressure air bag in the duct, the strong vibration can make the concrete quickly split the air bag, and the air will be discharged from the duct and the concrete will be poured smoothly. The concrete vibration aiding filling device can effectively solve the problem that the concrete is difficult to pour and fall due to some reasons by using vibration, and ensures the smooth progress of the underwater concrete pouring of the deep pile foundation.

Compared with the prior art, the present invention has the advantages of reducing the concrete pressure at the nozzle, and the smooth pouring of the concrete in the air discharge duct, ensuring the smooth progress of the underwater concrete pouring of the deep pile foundation, and making the pouring material more compact.

detailed description:

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Fig. 1 shows the structure of a vibration-assisted irrigation device provided by an embodiment of the present invention. For ease of description, only parts related to the embodiments of the present invention are shown.

The device includes 1. a vibrating device, 2. a conduit connector, and 3. a plug-in threaded connector; 3. At the lower end of the conduit connector, the threaded thread is the same as the conduit threaded thread and can be screwed into the conduit to fix it on the conduit connector, thereby forming an integral body with the vibrating hammer.

As shown in Figure 2, the diameter of the limiting device 4 of the plug-in threaded connector 3 changes suddenly, which is larger than the diameter of the upper opening of the plug-in threaded connector 3, so that the threaded connector 3 is restricted on the catheter connector, making it a Integral, and the plug-in threaded connector 3 can move up and down freely, so that it can be rotated like a threaded mouth at the end of a catheter. Simultaneously, the diameter of the limiting device 4 is larger than the outer diameter of the conduit, so that the mouth of the conduit can be closely attached to the lower surface of the limiting device 4, which is convenient for vibration force transmission.

The application principle of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the device includes a vibration device, a catheter connector, and a plug-in threaded connector. When in use, lift the plug-in threaded connector 3 to expose the stop device 4 of the plug-in thread connector, and fit the lower surface of the stop device of the plug-in thread connector tightly to the end of the conduit port , and then the plug-in threaded connector 3 is put down, screwed into the wire port at the end of the catheter, and the catheter and the catheter connector are tightly fixed together to form a whole.

When in use, the vibrating device 1 is turned on to vibrate the hammer, and the vibration of the vibrating hammer is transmitted to the end of the catheter through the catheter connector 2 . Under the action of the plug-in threaded connector 3, the catheter connector 2 is tightly connected with the catheter, and the vibration of the catheter connector 2 is transmitted to the catheter, thereby driving the vibration of the catheter.

The concrete piled up at the nozzle flows and disperses rapidly under the action of vibration, the pressure at the nozzle decreases, and the concrete in the pipe can fall smoothly; the concrete deposited in the pipe can also be scattered under the action of vibration; The frequency vibration can make the concrete enter the air bag, split the air bag, and let the air out.

The concrete vibration aiding filling device can effectively solve the problem that the concrete is difficult to flow and gather at the outlet of the conduit due to the small slump of the concrete during the pouring process by driving the concrete conduit to vibrate, so that the pressure at the end of the conduit is greater than the concrete pressure in the conduit, and high-pressure air pockets are generated in the conduit. Concrete It is difficult to pour concrete due to reasons such as siltation and blockage in the conduit. Ensure the smooth progress of deep pile foundation underwater concrete pouring.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention.
