Description

Technical Field

[0001] This application relates to the field of water conservancy engineering construction technology, and in particular to a sealing structure for an existing venting culvert. Background Technology

[0002] Traditional methods for sealing the bottom outlet of a dam diversion channel typically employ one of the following approaches: Cement mortar sealing: Cement mortar is piped or pumped into the bottom outlet, filling it completely. The mortar then hardens to form a seal. This method is more challenging, requiring complete filling and hardening of the mortar within the bottom outlet. Longer pipes can lead to insufficient grouting in certain sections or leakage of uncured mortar, resulting in poor sealing. Steel plate sealing: Steel plates are used to seal the bottom outlet. Typically, appropriately sized steel plates are prefabricated and installed inside the bottom outlet using hoisting or pushing methods to achieve a seal. This method is also more difficult, requiring suitable hoisting or pushing equipment and ensuring a tight seal between the steel plate and the bottom outlet.

[0003] During the sealing of the diversion bottom outlet of the dam, traditional sealing methods suffer from problems such as poor sealing effect, high construction difficulty, and low safety, affecting the progress and quality of the project. A new sealing structure is needed to improve the sealing effect, reduce construction difficulty, and enhance safety. Utility Model Content

[0004] To solve or partially solve the problems existing in the related technologies, this application provides a sealing structure for an existing venting culvert, which is divided into three sections from the outlet to the middle and then to the inlet, for backfilling and grouting to ensure that the backfill is compacted.

[0005] The first aspect of this application provides a sealing structure for an existing vented culvert, comprising: a grouting pipe, a filling pipe, an exhaust pipe, and a sealing plate. The sealing plate is installed at both ends of the culvert to form a sealed structure with the culvert pipe to prevent the grouting mortar from flowing out. The sealing plate has grouting holes and exhaust holes. The grouting holes are used to install the grouting pipe. The grouting pipe penetrates the culvert pipe laterally and has grout outlet holes to achieve grouting at both ends of the culvert. The exhaust holes are used to install the exhaust pipe. The grouting pipe is arranged corresponding to the middle of the culvert, penetrates the culvert pipe at the bottom and extends vertically to the top of the dam to achieve grouting in the middle of the culvert.

[0006] The grouting pipe is connected to the inner wall of the bottom culvert pipe by expansion bolts and fixing flat steel.

[0007] The grouting pipe has a grout discharge hole on its front and rear sides, and the grout discharge hole is sealed with double-layer kraft paper before being embedded.

[0008] The technical solution provided in this application may include the following beneficial effects:

[0009] This application provides a sealing structure for an existing vented culvert, which enables simultaneous backfilling and grouting of the culvert in three sections from the outlet to the middle and the inlet, ensuring dense backfilling. This solves the problems of poor sealing effect, high construction difficulty, and low safety in the prior art, and ensures that the mortar is filled and solidified in the bottom hole, effectively preventing the loss of cement mortar.

[0023] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0024] As shown in the figure, a sealing structure for an existing vented culvert 1 includes: a grouting pipe 6, a filling pipe 3, an vent pipe 4, and a sealing plate 5. The two ends of the culvert 1 are sealed using the sealing plate 5, which is made of 1cm steel plate, forming a sealed structure with the culvert 1 to prevent mortar leakage during grouting. The sealing plate 5 has grouting holes and vent holes. The vent holes are used to install the vent pipe 4, and the grouting holes are used to install the filling pipe 3. The filling pipe 3 horizontally penetrates the culvert 1, extending to the outlet and inlet of the culvert 1 at both ends, respectively, and is connected to the inner wall of the culvert 1 via expansion bolts 7 and fixing flat steel 8. A grout discharge hole is provided on the front and rear sides of the filling pipe 3. The grout discharge hole is used for grouting at both ends of the culvert 1, and is sealed with double-layer kraft paper before being embedded.

[0025] A grouting pipe 6 is installed in the middle of the bottom culvert 1. The bottom of the grouting pipe 6 penetrates the bottom culvert 1 and extends vertically to the top of the dam to achieve grouting in the middle of the bottom culvert 1. The bottom culvert 1 is divided into three construction sections from the outlet to the inlet: the first construction section, the second construction section, and the third construction section. The first and third construction sections are grouted through the grout outlet holes, while the second construction section is grouted through the grouting pipe 6. The mortar solidification of the three construction sections is optimized simultaneously to ensure the sealing effect.

[0026] The working process of this structure:

[0027] Both ends of the bottom culvert 1 are sealed with 1cm steel plates, with grouting holes and venting holes pre-drilled on the steel plates. Grouting pipe 3 and venting pipe 4 are installed. At the corresponding position of the bottom culvert 1 on the dam crest, a grouting hole 2 is drilled using a geological drill (a sleeve is installed inside the hole in the earth-rock dam). A grouting pipe 6 is installed inside the hole as the second grout outlet. Finally, the bottom culvert 1 is backfilled and grouted in three sections from the outlet to the middle to the inlet, forming a structure for sealing the existing bottom culvert 1 for dam upgrading and renovation.
