A kind of intelligence grout sleeve is equipped with close as shown in Figure 1, including sleeve body 1 at the both ends open of sleeve body 1
Seal 2, sleeve body 1 is interior to be equipped at least two thermistor 7, and each thermistor 7 is connect with two conducting wires 11, two conducting wires
11 one end not connecting with thermistor 7 and multimeter 12 are connected, and distance of the thermistor 7 apart from left side sealing ring 2 be 3 ~
5mm, sleeve body 1 are tubular structure, and internal cavity is the chamber 10 that is in the milk, and are equipped with two sections of reinforcing bars 13 waiting in grouting chamber 10,
Sleeve body 1 is equipped with plasma discharge hole 3 and grout hole 4, and sealing ring 2 is equipped with perforation, and two conducting wires 11 pass through same wear
Hole is connected with the multimeter 12 being set to outside sleeve body 1, and conducting wire 11 is made of cast iron materials, on the inner wall of sleeve body 1
Equipped with stressed collar 5, several stressed collars 5 are arranged along 1 inner wall interval of sleeve body, and the space between adjacent stressed collar 5 is shearing
Slot 6, thermistor 7 are two, be uniformly provided close to sealing ring 2 and plasma discharge hole 3 from it is left it is several first shearing slot 6 in,
And it is mutually 180 degree, and thermistor 7 is three, it is also provided close in sealing ring 2 and first shearing slot 6 in plasma discharge hole 3, point
It is distributed on three Along ents in 1 circumference of sleeve body, middle part is equipped with reinforcing bar limited block 9, reinforcing bar in 1 internal cavity of sleeve body
9 one end of limited block is connected and fixed with 1 inner wall of sleeve body.
A kind of application method from the intelligent grout sleeve of perception, it is characterised in that：
Step 1: production sleeve body 1：Sleeve body 1 is made, has stressed collar 5, reinforcing bar limited block in sleeve body 1
9, plasma discharge hole 3 and grout hole 4；
Step 2: laying thermistor 7：Thermistor 7 through insulation processing is laid in inside sleeve body 1；
Step 3: being in the milk to sleeve body 1：Two sections of reinforcing bars 13 waiting are inserted into sleeve body 1, to sleeve body
Grouting material 8 is poured into 1；
Step 4: the monitoring that grouting is horizontal：The temperature in the perfusion of grouting material 8 and hardening process is measured using thermistor 7
Variation realizes the horizontal monitoring of the grouting of grouting material 8 according to the temperature variations of grouting material 8；When multimeter 12 registration not
When variation, grouting material 8 does not impregnate thermistor 7, and grout sleeve is not up in the milk full；When the registration of multimeter 12 occurs obviously
When variation, grouting material 8 submerges thermistor 7, and it is full that grout sleeve reaches grouting；
Step 5: temperature detection：It is in the milk full afterwards using thermistor 7 persistently to the progress temperature detection of grouting material 8, temperature-sensitive
The temperature change of resistance 7 is transferred on multimeter 12 by conducting wire 11, records the temperature change on multimeter 12, until multimeter
12 numerical value no longer change, and represent grouting material hardening and complete, remove multimeter 12, so far, a kind of intelligence grouting set of the utility model
The use of cylinder is completed.
Specific the utility model is to realize said effect by following principles：In the specific implementation, one can be arranged again
Group control, i.e., separately set a thermistor and be put into grouting material pond, and referred to as external thermistor passes through ohm of multimeter
Shelves measure the resistance value of external thermistor, and then obtain the grouting material in grouting material pond i.e. wait be filled into inside grout sleeve
Grouting material temperature；Grouting material is perfused into grout sleeve, in the thermistor when being perfused full inside grout sleeve
Portion's thermistor can be immersed in grouting material, and the resistance value of thermistor is then measured by the ohms range of multimeter, works as temperature-sensitive
When the resistance value of resistance is identical as the external resistance value of thermistor, i.e., reached it is believed that being grouted into up to corresponding position i.e. grout sleeve
It is full to being in the milk, as shown in Figure 3.
In addition, when grouting material is perfused into grout sleeve, since the hardening process of grouting material can release heat（That is aquation
Heat）, the temperature that will lead to grouting material changes, therefore can use the temperature that thermistor is gone in measurement grouting material hardening process
Degree variation, according to the temperature variations of grouting material, can be realized the monitoring of the grouting level of grouting material.In practical projects,
When the entire grout sleeve of grouting material underfill, internal thermistor will not be immersed in grouting material, the hardening process of grouting material,
It not will lead to the temperature at internal thermistor position to change, the resistance value of internal thermistor will not change, such as
Shown in Fig. 2；When grouting material is full of entire grout sleeve, the thermistor in grout sleeve can be immersed in grouting material, be in the milk
The hardening process of material releases a large amount of heat of hydration, causes the temperature at internal thermistor that significant change occurs, and then causes interior
Significant change occurs for the resistance value of portion's thermistor, if significant change occurs for the resistance value of internal thermistor, i.e., it is believed that
Grouting reaches the position of internal thermistor, i.e., it is believed that grout sleeve to reach grouting full, therefore it is internal to pass through monitoring
The resistance change situation of thermistor goes to realize the monitoring of grout sleeve grouting level.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
