Description
Technical Field
The utility model relates to a hydrogeology monitoring facilities field especially relates to a pore opening closing means.
Background
In engineering investigation and drilling, the groundwater in a drill hole is often required to be observed for a long time, parameters such as the temperature and the water pressure of the groundwater with low pressure are generally observed, the groundwater does not flow out of an orifice of the drill hole, and a groundwater temperature and water pressure monitoring device adopts a monitoring instrument to be lowered into the drill hole to implement long-term monitoring. However, when the water temperature and the water pressure of the confined water need to be monitored in some special parts or areas with large orifice pressure and large water inflow, a monitoring instrument is difficult to drop into a hole, and when water inflow in a drill hole is not closed, only the water temperature and the water pressure of the orifice part can be monitored, the accuracy of monitored data is poor, and the purpose of effective monitoring cannot be achieved.
SUMMERY OF THE UTILITY MODEL
The utility model provides a technical problem provide a can realize carrying out long-term monitoring's drill way closing device to temperature, the water pressure of the confined water in gushing water drilling.
The utility model provides a technical scheme that its technical problem adopted is: the orifice closing device comprises an orifice pipe arranged on a drilling orifice and a sealing cover body, wherein the sealing cover body can be arranged at the end part of the orifice pipe in a sealing mode, a monitor is fixedly arranged inside the sealing cover body and is connected with external monitoring equipment through a wire penetrating through the sealing cover body in a sealing mode, a three-way pipe is arranged on the sealing cover body, and a valve capable of being adjusted in an opening and closing mode is arranged on the three-way pipe.
Further, the method comprises the following steps: the sealing cover body is in threaded connection and matching with the orifice pipe.
Further, the method comprises the following steps: the monitor comprises a water temperature monitor and a water pressure monitor.
Further, the method comprises the following steps: and a sealing rubber plug is arranged at the part of the lead penetrating through the sealing cover body and sleeved on the lead.
The utility model has the advantages that: through setting up drill way closing device after, can be very convenient realization carry out the shutoff to the drill way of gushing water drilling to can realize the long-term monitoring to the inside confined water of drilling in the shutoff, and can monitor the shutoff and the temperature of the drilling that have the confined water, water pressure effectively, guarantee monitoring data's validity. The utility model has the advantages of simple structure, convenient installation and low cost.
Drawings
Fig. 1 is a schematic structural view of an orifice closing device according to the present invention;
labeled as: the device comprises an orifice pipe 1, a sealing cover body 2, a monitor 3, a lead 4, a three-way pipe 5, a valve 6, a sealing rubber plug 7, an internal thread 8 and an external thread 9.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1, drill way closing means, including installing in the drill way pipe 1, still include sealed lid 2, sealed lid 2 can install on the tip of drill way pipe 1 sealedly, is provided with monitor 3 at sealed lid 2 inside fixed, monitor 3 is connected with outside monitoring facilities through sealed wire 4 that passes sealed lid 2, is provided with three-way pipe 5 on sealed lid 2, is provided with valve 6 that can on-off regulation on three-way pipe 5.
The orifice pipe 1 is generally a pipe body structure installed at the orifice of a drill hole during drilling construction, and the upper end of the orifice pipe 1 penetrates out of the ground surface corresponding to the drill hole to form a corresponding end. The utility model provides a sealed lid 2 is for being used for installing on the above-mentioned tip of orifice pipe 1 to the realization is to the closure of orifice pipe 1. Meanwhile, after the corresponding monitor 3 is arranged in the sealing cover body 2, after the sealing cover body 2 is installed on the orifice pipe 1, corresponding parameters of the confined water in the drill hole, such as the water temperature, the water pressure and other parameters of the confined water in the drill hole, can be monitored through the monitor 3; of course, without loss of generality, the corresponding monitor 3 may include two parts, a water temperature monitor and a water pressure monitor.
More specifically, in order to facilitate the disassembly and assembly connection of the sealing cover body 2 and the end part of the orifice pipe 1, the sealing cover body 2 and the orifice pipe 1 can be matched in a threaded connection way; as shown in fig. 1, a corresponding internal thread 8 can be provided at the end of the orifice tube 1, while a corresponding external thread 9 is provided on the closure body 2, by means of which internal thread 8 and external thread 9 a detachable screw connection is realized.
In the utility model, the sealing cover body 2 is provided with the corresponding three-way pipe 5 in a communicating way, which aims to continuously flush water from the end part of the orifice pipe 1 when the sealing cover body 2 is installed on the orifice pipe 1 due to the water flushing phenomenon of drilling, and after the three-way pipe 5 is arranged, the water flushing can be drained and decompressed through the three-way pipe 5 when the sealing cover body 2 is installed, thereby facilitating the installation of the sealing cover body 2; of course, without loss of generality, when the gland 2 is installed, the corresponding valve 6 on the three-way pipe 5 should be in an open state to allow the three-way pipe 5 to effectively discharge gushing water; and when the installation of the sealing cover body 2 is completed and parameters such as water temperature and water pressure of water in the drill hole need to be measured, the valve 6 should be closed to seal the orifice pipe 1, so that the accuracy of the monitored data such as the water temperature and the water pressure is ensured.
Additionally, the utility model provides a monitor 3 accessible corresponding wire 4 is connected with outside monitoring facilities to obtain the corresponding data that monitor 3 monitored. In order to ensure the sealing effect of the lead 4 passing through the sealing cover body 2, referring to fig. 1, the utility model is further provided with a sealing rubber plug 7 at the position where the lead 4 passes through the sealing cover body 2, and the sealing rubber plug is sleeved on the lead 4, and the lead 4 passes through the middle part of the sealing rubber plug 7; and the sealing rubber plug 7 is pressed and hermetically installed on the installation through hole arranged on the sealing cover body 2.
