Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a seepage prevention device for water conservancy and hydropower engineering construction. Background Technology

[0002] Hydraulic and hydropower engineering is a discipline that involves the utilization, development, and protection of water resources, as well as the construction and management of engineering facilities such as water conservancy hubs and hydropower stations. Water seepage prevention in hydraulic and hydropower engineering is a key link to ensure the safety and normal operation of the project. For hydraulic and hydropower engineering, water seepage may lead to damage to the internal structure.

[0003] The utility model application with application number 202222833411.1 discloses a seepage-proof structure for water conservancy projects. It uses a dual seepage-proof technology of precast concrete and asphalt layer to improve the seepage-proof effect of the water channel. The asphalt layer is connected to the precast concrete by pouring, which makes the operation more convenient and ensures that the thickness of the asphalt layer remains uniform. During the laying process, two L-shaped plates are sealed and connected to form a pouring channel above the joint of the two precast concretes. The joint can also be filled by pouring, which further facilitates the use of construction personnel and saves construction time.

[0004] However, when sealing the connection in the above-mentioned water conservancy engineering seepage prevention structure, the asphalt layer and precast concrete need to be connected by pouring. The cavity between the two sets of precast concrete cannot be connected, and there is still a possibility of water seepage. This means that each set of pouring holes needs to be poured when pouring asphalt, which makes the sealing connection inefficient. Therefore, this utility model proposes a water seepage prevention device for water conservancy and hydropower engineering construction to solve the problems existing in the prior art.

[0021] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0022] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown in the figure, this embodiment provides a seepage prevention device for water conservancy and hydropower engineering construction, including a precast irregular-shaped concrete slab 1, a splicing and connecting mechanism, an end sealing mechanism, and a stacking and positioning mechanism. The splicing and connecting mechanism includes a cavity 2, a pouring hole 3, an irregular splicing strip 4, an irregular splicing groove 5, a connecting hole 6, and a guide groove. The precast irregular-shaped concrete slab 1 has a cavity 2 inside, and pouring holes 3 are symmetrically opened on the front and back of the precast irregular-shaped concrete slab 1. An irregular splicing strip 4 is fixed on one side of the precast irregular-shaped concrete slab 1, and an irregular splicing groove 5 is opened on the other side of the precast irregular-shaped concrete slab 1. The irregular splicing strip 4 and the irregular splicing groove 5 are arranged at the bottom with connecting holes 6, and a corresponding connecting hole is opened above the connecting hole 6. The guide groove 7, the irregular splicing strip 4 and the irregular splicing groove 5 are spliced ​​together, and the positions of the connecting holes 6 are corresponding and fit together. During installation, the precast irregular concrete slab 1 is placed in the water channel with the ends aligned. The irregular splicing strip 4 of the latter group is inserted into the irregular splicing groove 5 of the former group, so that the precast irregular concrete slab 1 is tightly arranged. Asphalt is poured into the cavity 2 through the pouring hole 3 for filling. The poured asphalt fills and connects the cavity 2 and the gap through the connecting hole 6 and the guide groove, so that the precast irregular concrete slab 1 is connected and sealed, effectively eliminating the possibility of water seepage. The end of the precast irregular concrete slab 1 is provided with an end sealing mechanism, and a stacking positioning mechanism is provided above the precast irregular concrete slab 1.

[0023] The end sealing mechanism includes irregularly shaped sealing blocks 8, irregularly shaped sealing strips 9, and irregularly shaped sealing grooves. The end of the precast irregularly shaped concrete slab 1 is provided with an irregularly shaped sealing block 8. An irregularly shaped sealing strip 9 is fixed on one side of the irregularly shaped sealing block 8, and an irregularly shaped sealing groove 10 is opened on the other side of the irregularly shaped sealing block 8. The irregularly shaped sealing strip 9 and the irregularly shaped splicing groove 5 are spliced ​​together to seal. The irregularly shaped sealing groove 10 and the irregularly shaped splicing strip 4 are spliced ​​together to seal. After the precast irregularly shaped concrete slab 1 is arranged and spliced ​​in the water channel, the irregularly shaped sealing blocks 8 are spliced ​​to the end to seal, so asphalt will not flow out from the connecting hole 6 at the end due to lack of sealing when pouring asphalt, thus affecting the water-proof performance.

[0024] The stacking positioning mechanism includes positioning posts 11, positioning grooves 12, and stacking support bars 13. Positioning posts 11 are fixedly installed at the lower corners of the four corners of the precast irregular concrete slab 1, and positioning grooves 12 are opened at the upper corners of the four corners of the precast irregular concrete slab 1. Stacking support bars 13 are fixedly installed in the middle of the precast irregular concrete slab 1. The positioning posts 11 and positioning grooves 12 are vertically aligned. The stacking support bars 13 are attached to and support the previous set of precast irregular concrete slabs 1. When the precast irregular concrete slabs 1 are stacked and placed, the positioning posts 11 are inserted into the positioning grooves 12, which effectively prevents the precast irregular concrete slabs 1 from shifting during stacking. During stacking, the stacking support bars 13 support the upper precast irregular concrete slabs 1 to facilitate stacking and transportation.

[0025] Limiting strips 14 are symmetrically arranged and fixed on the outer side of the precast irregular concrete slab 1. Extending guard plates 15 are symmetrically fixed on one side of the precast irregular concrete slab 1. During the laying, the limiting strips 14 are inserted into the water channel to increase friction and prevent the precast irregular concrete slab 1 from shifting after splicing. The extending guard plates 15 cover the gaps after splicing and extend the service life.

[0026] During the construction of this water conservancy and hydropower project, the anti-seepage device is laid by sequentially splicing precast irregularly shaped concrete slabs into the water channel. Irregularly shaped splicing strips are inserted into irregularly shaped splicing grooves for splicing. After the splicing is completed, irregularly shaped sealing blocks are spliced ​​into the ends, and irregularly shaped sealing strips are inserted into the irregularly shaped splicing grooves at the ends. The irregularly shaped sealing grooves are inserted onto the irregularly shaped splicing strips at the ends to seal the cavity ends. After splicing, asphalt is poured into the cavity through the pouring holes, and the connecting holes are used to connect and allow the asphalt to fill the cavity, achieving an anti-seepage seal. When the precast irregularly shaped concrete slabs are stacked and transported, positioning posts are inserted into positioning grooves for limiting their position, and stacking support strips support the upper precast irregularly shaped concrete slabs, effectively preventing displacement during transportation.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
