It should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" etc. indicated by the accompanying drawings are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0053] like Figures 1-13 As shown, this embodiment proposes a termite control dam structure, which features simple construction, low cost, comprehensive and thorough termite control, and can meet the needs of comprehensive termite control in dams. The dam structure includes a dam 1 and a multifunctional termite control device 2. (See diagram below.) Figure 2 As shown, the multifunctional termite control device 2 is systematically deployed within a dam infested with termites. The multifunctional termite control device 2 includes a seepage pressure monitoring pipe 21, a termite trapping device 22, a grouting device 23, a seepage pressure monitoring device 24, and a cover plate 25. The termite control device 2 can be installed either by burying it during dam construction or by drilling it into existing dam sections. The termite control device 2 can be deployed systematically or partially on the dam, but at least three devices should be installed on each dam section to better monitor water pressure changes within the dam. When abnormal water pressure changes occur within the dam, it can be promptly investigated whether the cause is termite infestation and appropriate control measures can be taken.

[0054] like Figure 3 As shown, the seepage pressure monitoring pipe 21 is embedded within the main structure of the dam 1 and includes a steel pipe 21a, a grouting hole 21b, a one-way rubber sleeve 21c (i.e., a one-way valve), a seepage inlet hole 21d, geotextile 21e, and steel wire 21f. The steel pipe 21a of the seepage pressure monitoring pipe 21 can be divided into upper, middle, and lower sections. The middle section of the steel pipe 21a has a grouting hole 21b, and the lower section has a seepage inlet hole 21d. A one-way rubber sleeve 21c is installed outside the grouting hole 21b to control the unidirectional outflow of grout. The seepage inlet hole 21d is wrapped with geotextile 21e, and the end of the geotextile 21e is bound with steel wire 21f. During dam operation, water pressure within the dam can enter the steel pipe 21a through the seepage inlet hole 21d to achieve seepage pressure monitoring.

[0055] The one-way rubber sleeve 21c of the seepage pressure monitoring pipe 21 can open outward during grouting to allow grout 23e to enter the dam. When grouting is finished, it automatically closes to prevent external impurities from entering the seepage pressure monitoring pipe 21, thus achieving the effect of one-way grouting.

[0056] The upper section of the steel pipe 21a is provided with a termite trapping device 22. The termite trapping device 22 comprises a steel shell 22a, an attracting hole 22b, a trapping bag 22c, an attracting bait wood 22d and a monitoring module 22e. The steel shell 22a is connected to the steel pipe 21a of the osmotic pressure monitoring pipe 21 by welding, and a containing space is formed between the shell 22a and the osmotic pressure monitoring pipe 21. The steel shell 22a is provided with the attracting hole 22b, and the containing space is provided with the trapping bag 22c, the attracting bait wood 22d and the monitoring module 22e. The attracting bait wood 22d is used to attract termites in the dam to the containing space through the attracting hole 22b. The trapping bag 22c is used to trap the termites in the containing space. The monitoring module 22e is used to monitor the termite infestation in the containing space in real time and alarm.

[0057] Preferably, the attracting hole 22b has a small aperture to prevent other irrelevant organisms from entering while allowing termites to enter. The top of the termite trapping device 22 is provided with a cover plate 25 to facilitate replacement of the trapping bag 22c, the attracting bait wood 22d and the monitoring module 22e. When termite infestation is found or the monitoring module 22e alarms, the cover plate 25 can be opened to spray powder on the live termites in the termite trapping device 22 for other control measures. In addition, the number of the trapping bag 22c, the attracting bait wood 22d and the monitoring module 22e in the termite trapping device 22 can be adjusted flexibly according to the actual termite infestation, and other termite trapping drugs or devices can be buried to achieve better comprehensive control effect.

The cable 24b comprises a cable segment one and a cable segment two. The cable segment one is arranged in the osmotic pressure monitoring pipe 21 and connected to the osmometer 24a at the bottom. The cable segment two is led to a power distribution equipment through the cable tube 24d. The cable segment one and the cable segment two are electrically connected through the cable joint 24c, which facilitates the implementation of grouting measures after the osmometer 24a and the cable segment one are removed.

[0059] When the termite infestation of the dam is serious or the osmotic pressure monitoring device 24 shows that the water pressure in the dam is abnormal, grouting control measures can be taken. By pulling out the cable joint 24c of the osmotic pressure monitoring device 24, the osmometer 24a and the cable segment one are removed, and then the grouting device 23 is inserted into the osmotic pressure monitoring pipe 21 to start the grouting measures. Figure 4As shown, the grouting device 23 comprises a grout inlet pipe 23a, a sealing ring 23b, a grout outlet pipe 23c and grout outlet holes 23d. One end of the grout inlet pipe 23a is connected to the grouting related equipment, and the other end extends into the osmotic pressure monitoring pipe 21 and is connected to the sealing ring 23b. The sealing ring 23b has two layers, which are arranged at the upper and lower parts of the middle section of the osmotic pressure monitoring pipe 21 respectively. The grout outlet pipe 23c is arranged between the two layers of the sealing ring 23b, and the surface of the grout outlet pipe 23c is provided with the grout outlet holes 23d. When the grouting is implemented, the grout 23e is pressed into the grout outlet pipe 23c from the grout inlet pipe 23a, and then enters the steel pipe 21a of the osmotic pressure monitoring pipe 21 from the grout outlet holes 23d on the surface of the grout outlet pipe 23c. Subsequently, the grout 23e pushes open the one-way rubber sleeve 21c and enters the dam through the grouting hole 21b, so as to realize the grouting filling of the ant nest cavity. The two layers of the sealing ring 23b of the grouting device 23 can be adjusted in height according to the construction requirements, so as to realize the grouting in different height ranges of the dam 1.

[0060] Preferably, the grout 23e of the grouting device 23 can be composed of cement, yellow clay, environmentally friendly prevention and control drugs, water and the like, and a proper amount of expanding agent, early strength agent and water reducing agent and the like is added. Under the premise of environmental protection and prevention and control, the grout 23e can penetrate into the ant nest cavity as far as possible, and the grout 23e can be solidified in time and combined well with the original dam material.

[0061] Preferably, the grouting holes 21b and the osmotic pressure inlet holes 21d of the osmotic pressure monitoring pipe 21 and the grout outlet holes 23d of the grouting device 23 should be arranged in a plum blossom shape on the surface of the pipe, so as to achieve better grouting or water seepage effect.
