Other features and advantages of the utility model will be set forth in the following description, and, partly from manual, become apparent, or understand by implementing the utility model.The purpose of this utility model and other advantages can be realized and be obtained by specifically noted structure in manual, claims and accompanying drawing.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will do simple introduction to needed accompanying drawing in embodiment or description of the Prior Art below:
Fig. 1 is according to the structure chart of the prestressed grouting system of an embodiment of the utility model.
Detailed description of the invention
Describe embodiment of the present utility model in detail below with reference to drawings and Examples, to the utility model, how application technology means solve technical problem whereby, and the implementation procedure of reaching technique effect can fully understand and implement according to this.It should be noted that, only otherwise form conflict, each feature in each embodiment and each embodiment in the utility model can mutually combine, and the technical scheme forming is all within protection domain of the present utility model.
Meanwhile, in the following description, many details are set forth for illustrative purposes, so that the thorough understanding to the utility model embodiment to be provided.But, it will be apparent to those skilled in the art that the utility model can detail or described ad hoc fashion here implement.
Fig. 1 shows the structure chart of the prestressed grouting system that the present embodiment provides.
As shown in Figure 1, this prestressed grouting system comprises prestressed grouting equipment and prestressed girder hole.Wherein, prestressed grouting equipment comprises agitator 101, liquid level detector 103, grout pump 104, controller 105 and circulation line.
Agitator 101 is for generation of also output grouting, and it comprises the first agitator 101a and the second agitator 101b.Wherein, the mixing speed of the first agitator 101a is greater than the mixing speed of the second agitator 101b.The first agitator 101a is used for making slurries, so the first agitator 101a also can be called cement slurry preparing barrel.The second agitator 101b is used for storing slurries, so the second agitator 101b also can be called slurry storing tank.
As can be seen from Figure 1, in the present embodiment, the bottom of the first agitator 101a and the second agitator 101b adopts inverted cone-shaped structure, and the grout outlet 102 of the second agitator 101b is positioned at the lowermost end of this inverted cone-shaped structure.Inverted cone-shaped structure is conducive to the discharge of slurries and the cleaning of agitator inside, and grout outlet position 102 can ensure whole eliminatings of slurries in agitator in the lowermost end of inverted cone-shaped structure.
Liquid level detector 103 is arranged between the grout outlet 102 and grout pump 104 of the second agitator 101b, and particularly, it is arranged on the tube wall of grout outlet 102.The signal output part of liquid level detector 102 is connected with controller 105, for detection of the liquid level of slurries in the second agitator 101b, and according to detecting that liquid level produces corresponding liquid level signal.Controller 105 produces corresponding grout pump control signal according to this liquid level signal, carrys out the running status of controlled grouting pump.
In the present embodiment, liquid level detector 103 adopts capacitance type liquid level proximity transducer.When the level value that the liquid level signal detecting when capacitance type liquid level proximity transducer characterizes is less than or equal to default liquid level threshold value, this liquid level range sensor that shows the slurries in the second agitator 101b is now nearer, and the surplus of the slurries in the second agitator 101b is less.This Time Controller 105 carries out Real-Time Monitoring according to the liquid level signal receiving to liquid level of slurry, and it is out of service to carry out controlled grouting pump 104 according to current liquid level signal generation stoppage in transit signal, thereby has reached the object that prevents that grout pump 104 from dry grinding.
When the level value that the liquid level signal detecting when liquid level sensor 103 characterizes is greater than default liquid level threshold value,, there is not the risk that causes grout pump 104 to be dry grinded in the slurries abundance that this shows in the second agitator 101b now.This Time Controller 105 produces run signal to be carried out controlled grouting pump 104 and normally moves.
It should be noted that, in other embodiment of the present utility model, liquid level detector can also adopt other rational devices to carry out the detection of liquid level of slurry in agitator, such as pressure sensor etc., the fluid level condition that reflects slurries in agitator by the pressure at detecting sensor set-point place, the utility model is not limited to this.
The prestressed grouting equipment that the present embodiment provides also comprises circulation line, and this circulation line and prestressed girder hole form two circulation lines.
As shown in Figure 1, one end of the feed pipe for mortar 107 of circulation line is connected with the output of grout pump 104, and the other end is connected with the one end of the first beam hole 106a in prestressed girder hole.Slurry recovering tube 108 its one end are connected with the liquid mouth that returns of agitator 101b, and the other end is connected with the one end of the second beam hole 106b in prestressed girder hole.Tube connector 109 is communicated with the other end of the first beam hole 106a with the other end of the second beam hole 106b.Like this, in the time that grouting equipment is worked, grout pump 104 is in the milk in the first beam hole 106a by feed pipe for mortar 107, and grouting is filled with to the second beam hole 106b by tube connector 109, grout pump 104 is proceeded grouting, and now grouting will be back in the second agitator 101b by slurry recovering tube 108.The grouting way of this dual control circulation mud jacking can be guaranteed the density of slurries, thereby reaches good grouting effect.
Existing prestressed grouting equipment adopts the method for manual observation to observe the surplus of slurries in agitator, judge whether grout pump out of service with this, to prevent grout pump dry grinding, and prestressed grouting equipment provided by the utility model adopts liquid level detector to detect the surplus of slurries in agitator.So compared to existing prestressed grouting equipment, this device structure is simple, can detect liquid level real-time, quickly and accurately, this just make this equipment can be more accurately, reliably grout pump is controlled, thereby effectively prevent that grout pump from dry grinding phenomenon occurring, extend the application life of equipment, thereby greatly reduced the after-sales service cost of equipment, saved construction cost.
Meanwhile, needed human cost when this equipment adopts liquid level detector can also reduce grouting equipment operation, the running cost that this has also reduced whole equipment, the safety that has improved whole equipment.
