[0016] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] The utility model provides a leakage collecting and draining device for grouting of fissures in grouting rock masses of caves. The device is in the shape of a groove with ears as a whole. The main body is formed by stamping of thin steel plates. When in use, the groove ears on both sides of the groove are close to the rock mass. The steel plate groove is filled with water-absorbing material, the position of the groove ears is fixed with water-stopping rubber strips, and the two ends of the groove body are fixed with nets. The thin steel plate has good plasticity and is easy to deform. The water-absorbing material is a lightweight material with stable properties. It is wrapped by geotextile and filled into the steel plate groove. The water-stopping rubber strip has a certain water absorption and expansion property and is stable in nature. The net has good flexibility and good adaptability to the deformation of the thin steel plate groove. The utility model is usually set at the cracks of the rock mass of cultural relics, and is used to absorb and collect the leakage that may be generated in the fissure grouting project, and drain it to a safe area through the bottom of the device to protect the cultural relics from pollution and damage. The utility model is a fissure leakage collecting and draining device with simple design, convenient use and strong practicality.

[0018] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a leakage collecting and draining device for grouting of rock mass fissures in caves, comprising a steel plate trough 1, groove ears 2 are arranged on both sides of the notch of the steel plate trough 1, water-stopping rubber strips 3 are arranged on the surface of the groove ears 2, the steel plate trough 1 is filled with water-absorbing material 4, the surface of the water-absorbing material 4 is covered with geotextile 6, and the geotextile 6 is wrapped tightly and then placed in the steel plate trough 1, and installation holes for installing a bag net 5 are opened at both ends of the steel plate trough 1, and the bag net 5 is fixedly installed at both ends of the steel plate trough 1 through the installation holes. The bag net 5 is a flexible material.

[0019] In the utility model, the steel plate trough 1 is provided with a trough ear 2 adapted to fit the surface of the cultural relic rock mass. The thickness and size of the steel plate trough 1 are adaptively adjusted according to the crack occurrence and leakage situation. The length of the water-stop rubber strip 3 is set to adapt to the length of the steel plate trough 1, and the thickness is adaptively adjusted according to the flatness of the cultural relic rock mass. The water-absorbent material 4 is a lightweight, stacked material with stable properties, which is wrapped by a geotextile 6 and filled into the steel plate trough 1. The volume of the water-absorbent material 4 is adaptively adjusted according to the size of the steel plate trough 1. The net 5 is a flexible material, which adapts to the deformation of the steel plate trough 1, is fixed at both ends of the steel plate trough 1, and constrains the water-absorbent material 4 in the steel plate trough 1.

[0020] The specific features are as follows:

[0021] In order to achieve a good adaptability to the cracks in the cultural relic rock mass, the steel plate trough 1 provided by the utility model is integrally formed by stamping of thin steel plates, and the thickness is adaptively adjusted according to the length of the steel plate trough, taking into account the larger structural deflection and adapting to the occurrence of rock mass cracks.

[0022] In order to achieve a good fitting effect on the cultural relics rock mass on both sides of the crack, the waterproof rubber strip 3 provided by the utility model has the characteristic of water absorption and expansion, and the thickness selection should be adapted to the flatness of the rock mass surface.

[0023] In order to achieve better absorption and collection of leaked liquid and prevent the leaked liquid from flowing by gravity and contaminating cultural relics, the steel plate trough 1 is filled with absorbent material and tightly wrapped with geotextile to improve the fit with the rock mass cracks. For large leaks, it plays a role of storage and buffering. The absorbent material is loose and stacked material, which adapts to the adjustment and deformation of the steel plate trough 1. The filling amount is adaptively adjusted according to the size of the steel plate trough 1 and the degree of crack leakage.

[0024] In order to fix the water-absorbing material in the steel plate trough, a bag net 5 is fixed at both ends of the trough. The bag net 5 is made of flexible material and can adapt to the deformation of the steel plate trough 1. The bag net 5 is semi-closed and does not affect the drainage path of the liquid leakage at the bottom of the steel plate trough.

[0025] The material selection of the waterproof rubber strip 3, the water-absorbing material 4 and the net 5 should take into account the stability of the property, and should not react with the contact materials such as the cultural relic rock mass and slurry, so as to protect the cultural relics from pollution and damage.

[0026] In the specific implementation process, after the steel plate trough 1 is stamped, installation holes for the net 5 are reserved at both ends. According to the size of the trough ear 2, the waterproof rubber strip 3 of appropriate size is cut, and the waterproof rubber strip 3 is located on the surface of the trough ear 2 and is tightly pasted along the inner edge of the steel plate trough 1. According to the net size of the steel plate trough 1, the geotextile 6 of appropriate size is cut, and the dense water-absorbing material 4 is wrapped and placed in the steel plate trough 1. The net 5 is adjusted and fixed through the installation holes reserved at both ends of the steel plate trough 1.

[0027] When the device is in use, the groove ears 2 are close to the rock masses on both sides of the crack, and the axis of the steel plate groove 1 is aligned with the crack as much as possible. According to the occurrence characteristics of the crack, the placement of the device is adjusted so that the leakage generated during the crack grouting project falls into the steel plate groove 1, is absorbed and buffered by the water-absorbing material 4, and is drained to a safe area through the drainage holes at both ends of the bottom of the steel plate groove 1, protecting the cultural relics from pollution and damage.

[0028] The utility model provides a leakage collecting and draining device for grouting of cracks in grouting of grouting rock mass, which is usually arranged at the cracks of cultural relics rock mass, and is used to absorb and collect leakage that may be generated in the crack grouting project, and drain it to a safe area through the bottom of the device, so as to protect the cultural relics from pollution and damage. The utility model is a leakage collecting and draining device for cracks, which is simple in design, easy to use and highly practical.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be considered as the protection scope of the present invention.
