It should be noted that, in the present application, technical features in examples and embodiments may be combined with each other without conflict, and the detailed description in the specific embodiment should be understood as an explanation of the gist of the present application and should not be construed as an improper limitation to the present application.
Before describing the embodiments of the present application, it is necessary to analyze the reason that the pressure detector is vulnerable to damage and the grouting pressure monitored in the prior art has a certain difference from the actual grouting pressure of the formation, and obtain the technical solution of the embodiments of the present application through reasonable analysis.
The pressure detector among the prior art is installed in grouting pump department, and the transport distance between grouting pump and the grouting hole is far away usually, can produce certain loss of pressure, and the position that grouting pump was located receives external environment influences such as construction, and the pressure of reading also has certain error, and the grouting pressure who consequently monitors has certain difference with the actual grouting pressure in stratum. However, when the pressure detector is arranged close to the grouting hole, the grouting pipe at the grouting hole needs to be moved repeatedly for vibration, so that the grouting pipe at the grouting hole can drive the pressure detector to move repeatedly, and in the process, the pressure detector can be collided by friction, so that the pressure detector is easily damaged.
In view of this, an embodiment of the present application provides a grouting apparatus, please refer to fig. 1, including a grouting pump 1, a first grouting pipe 2, a second grouting pipe 3, and a first pressure detecting device 4. Grouting pump 1, first slip casting pipe 2 and second slip casting pipe 3 connect gradually, and first slip casting pipe 2 is the rigid pipe, and second slip casting pipe 3 is the hose, and second slip casting pipe 3 is connected to slip casting hole 6, and first pressure measurement 4 sets up on first slip casting pipe 2. When the second grouting pipe 3 moves at the grouting hole 6, the second grouting pipe 3 transmits displacement to the first grouting pipe 2, and the second grouting pipe 3 buffers the displacement.
Because second slip casting pipe 3 is the hose, can cushion the displacement of second slip casting pipe 3 to the transmission of first slip casting pipe 2, first slip casting pipe 2 is as the rigid tube, the amplitude of the displacement that first slip casting pipe 2 and install first pressure measurement device 4 on first slip casting pipe 2 removed is less than the amplitude of the displacement that second slip casting pipe 3 removed, even first slip casting pipe 2 and install first pressure measurement device 4 on first slip casting pipe 2 can not follow the removal of second slip casting pipe 3 and remove, consequently, first pressure measurement device 4 has been reduced because remove and impaired possibility. In the moving process of the second grouting pipe 3, the second grouting pipe 3 as a hose can be deformed adaptively to play a role in buffering. Furthermore, first pressure measurement device 4 sets up on first slip casting pipe 2, and first slip casting pipe 2 is located between slip casting pump 1 and grouting hole 6, carries out pressure measurement for in the prior art in the position department of slip casting pump 1, and first pressure measurement device 4 of this application embodiment is closer to grouting hole 6, and the slip casting pressure that measures is closer to the actual slip casting pressure of stratum.
It is understood that the second grout tube 3 is more flexible than the first grout tube 2.
It will be appreciated that the hose is configured to dampen by deformation the displacement of the second injection pipe 3 transmitted to the first injection pipe 2.
The hose may be, for example, a rubber tube or a silicone tube.
It will be appreciated that the rigid pipe is configured to bear the load caused by the movement of the second grouting pipe 3 without deforming, which also alleviates to some extent the disturbance of the first pressure detection device 4 mounted on the rigid pipe due to the movement of the second grouting pipe 3, reducing the possibility of damage to the first pressure detection device 4.
Illustratively, the rigid pipe may be a steel pipe, such as a galvanized steel pipe.
In one embodiment, the first grouting pipe 2 may be fixed to the ground or the tunnel wall. In this way, after the first grouting pipe 2 is fixed as a rigid pipe, the first grouting pipe 2 is not affected by the movement of the second grouting pipe 3 at all, and the first grouting pipe 2 and the first pressure detection device 4 mounted on the first grouting pipe 2 do not move due to the movement of the second grouting pipe 3, thereby further reducing the possibility that the first pressure detection device 4 is damaged due to the movement.
In one embodiment, the first grouting pipe 2 may be fixed by a bracket mounted on the ground or on the tunnel wall, i.e. the first grouting pipe 2 is fixed on the ground or on the tunnel by a bracket. In this way, the first grout pipe 2 can be fixed to a more suitable position by the bracket.
In an embodiment, referring to fig. 1, the first pressure detecting device 4 includes a first pressure gauge 41 and a pressure sensor 42, and the first grouting pipe 2 is connected to the first pressure gauge 41 and the pressure sensor 42, respectively. So, measure the slip casting pressure in first slip casting pipe 2 respectively through first manometer 41 and pressure sensor 42, first manometer 41 shows pressure in first slip casting pipe 2 department and monitors slip casting pressure in order to supply on-the-spot operating personnel, and pressure sensor 42 converts the pressure in first slip casting pipe 2 into the signal of telecommunication and supplies monitoring system to gather the monitoring, carries out centralized monitoring to data.
In one embodiment, the first pressure gauge 41 may be a mechanical pressure gauge.
It is understood that during the grouting process of the tunnel, the slurry entering the corresponding first pressure gauge 41 and the pressure sensor 42 may cause blockage of the corresponding first pressure gauge 41 and the pressure sensor 42, and damage to the corresponding first pressure gauge 41 and the pressure sensor 42. In view of this, in an embodiment, referring to fig. 1, the first pressure detecting device 4 further includes a first slurry isolator 43 and a second slurry isolator 44, the first pressure gauge 41 is connected to the first grouting pipe 2 through the first slurry isolator 43, and the pressure sensor 42 is connected to the first grouting pipe 2 through the second slurry isolator 44. So, keep apart thick liquid and first manometer 41 through first oil thick liquid isolator 43, the slip casting pressure in the first slip casting pipe 2 can transmit first manometer 41 through fluid in the first oil thick liquid isolator 43 for the slip casting pressure in the first slip casting pipe 2 can be measured to first manometer 41, and the thick liquid in the first slip casting pipe 2 can not enter into first manometer 41 again, therefore first manometer 41 can not block up the damage because the thick liquid gets into. Isolate thick liquid and pressure sensor 42 through second oil thick liquid isolator 44, pressure sensor 42 can be transmitted to fluid in the first slip casting pipe 2 through the second oil thick liquid isolator 44 to grouting pressure for pressure sensor 42 can measure the grouting pressure in first slip casting pipe 2 and convert the signal of telecommunication into and supply monitoring system to monitor the collection, and the thick liquid in first slip casting pipe 2 can not enter into pressure sensor 42, and pressure sensor 42 can not block up the damage because the thick liquid gets into.
In an embodiment, referring to fig. 1, the grouting apparatus further includes a flow rate detection device 5, and the flow rate detection device 5 is disposed on the first grouting pipe 2. Therefore, the first grouting pipe 2 is a rigid pipe, the second grouting pipe 3 is a hose, and the flow detection device 5 is arranged on the first grouting pipe 2, so that the flow of the first grouting pipe 2 can be monitored; on the other hand, the possibility of damage to the flow rate detection device 5 due to movement can be reduced to some extent.
In one embodiment, the flow rate detection device 5 is a flow meter that converts the flow rate of the fluid in the first grouting pipe 2 into an electrical signal. So, the flowmeter converts the flow in the first slip casting pipe 2 into the signal of telecommunication, and the monitoring system of being convenient for monitors the collection, carries out centralized monitoring to data.
In one embodiment, the flow detecting device 5 may also be a mechanical flow meter. The flow data is typically indicated using a pointer, and the measured flow is displayed to the operator at the first grout pipe 2 by the indication of the pointer.
It is understood that the flow rate detection device 5 generally has a certain detection direction, and if the flow rate detection device 5 is installed reversely, the flow rate may not be detected. Accordingly, the detection direction of the flow rate detection device 5 coincides with the flow direction of the slurry. The flow direction of the slurry in the embodiment of the present application is from the grouting pump 1 to the grouting hole 6.
It can be understood that the flow rate detection device 5 needs to detect the amount of the slurry passing through the first grouting pipe 2, and needs to continuously pass through the flow meter, and normally, the flow rate detection device 5 is connected in series with the first grouting pipe 2. The pressure detection is different, as long as the first pressure detection device 4 is acted by the grout, the grouting pressure is fed back through the first pressure detection device 4, usually, a branch pipe can be formed on the first grouting pipe 2, and the first pressure detection device 4 is installed on the branch pipe of the first grouting pipe 2. Therefore, along the radial direction of the first grouting pipe 2, the first pressure detecting device 4 protrudes from the first grouting pipe 2 more than the flow detecting device 5, and when the distance from the first pressure detecting device 4 to the second grouting pipe 3 is smaller than or equal to the distance from the flow detecting device 5 to the second grouting pipe 3, the first pressure detecting device 4 is more likely to be damaged by the movement of the second grouting pipe 3. In view of the above, in one embodiment, referring to fig. 1, the flow rate detecting device 5 is located between the first pressure detecting device 4 and the second grouting pipe 3. So, first pressure measurement device 4 is located flow measurement device 5 and keeps away from the one end of second slip casting pipe 3, can weaken first pressure measurement device 4 to a certain extent and receive the impaired possibility of second slip casting pipe 3 removal in flow measurement device 5 relatively, though flow measurement device 5 is more close to second slip casting pipe 3, is more easily received the influence that second slip casting pipe 3 removed, but flow measurement device 5 installs and rises the degree of first slip casting pipe 2 on first slip casting pipe 2 and can not be so big like the degree of first pressure measurement device 4 protrusion in first slip casting pipe 2, can weaken flow measurement device 5 to a certain extent because the impaired possibility of second slip casting pipe 3 removal. Therefore, the position arrangement of the flow detection device 5 and the first pressure detection device 4 balances the influence of the movement of the second grouting pipe 3 on the possibility of damage to the flow detection device 5 and the first pressure detection device 4 respectively, and avoids the problem that damage factors of the flow detection device 5 and the first pressure detection device 4 are mutually superposed to cause the high possibility that one of the flow detection device 5 and the first pressure detection device 4 is damaged by the movement of the second grouting pipe 3.
In one embodiment, the grouting apparatus further comprises a second pressure detecting device, and the second pressure detecting device is disposed on the second grouting pipe 3. Thus, the second pressure detecting means is closer to the injection hole 6 and the measured injection pressure is closer to the actual formation pressure. Moreover, the second pressure detection device is closer to the grouting hole 6, the possibility that the second pressure detection device is damaged by the movement of the second grouting pipe 3 compared with the first pressure detection device 4 is higher, the service life of the second pressure detection device is generally unequal to that of the first pressure detection device 4, and the second pressure detection device and the first pressure detection device are staggered, so that the possibility that the second pressure detection device and the first pressure detection device 4 are damaged at the same time is lower, and in a complete grouting process, at least one of the first pressure detection device 4 and the second pressure detection device is normally in a normal working state and is not damaged, and the real-time monitoring of grouting pressure is facilitated.
In an embodiment, the second pressure detecting device includes a second pressure gauge and a third slurry isolator, and the second pressure gauge is connected to the second grouting pipe 3 through the third slurry isolator. So, keep apart second manometer and second slip casting pipe 3 through third oil slurry isolator, the slip casting pressure of thick liquid passes through fluid in the third oil slurry isolator in the second slip casting pipe 3 and transmits the second manometer, makes the slip casting pressure of thick liquid in the second slip casting pipe 3 can be measured to the second manometer, and fluid in the third oil slurry isolator can prevent the thick liquid to get into the second manometer, avoids causing the second manometer to block up the damage.
In one embodiment, the second pressure gauge is a mechanical pressure gauge.
In one embodiment, the grouting apparatus further includes a third grouting pipe connected between the first grouting pipe 2 and the grouting pump 1, and the third grouting pipe may be a hose. Therefore, the flexibility of pipeline layout is better, and the pipeline can be better arranged in a tunnel in a suitable mode.
