Embodiment Construction

[0052] The following is attached Figure 1-8 The application is described in further detail.

[0053] The embodiment of the present application discloses a kind of anti-seepage and reinforcement construction technology of the dam foundation of the water conservancy project. figure 1 , which mainly includes the following steps:

[0054] S1. Excavate the foundation trenches on the ground below the gate of the dam 1. The foundation trenches from upstream to downstream are the first construction foundation trench 2, the gentle support foundation trench 3 and the second construction foundation trench 4. structure reference figure 2 ;

[0055] In this step, the excavator is used to excavate the foundation trenches, the size of each foundation trench is determined according to the construction drawings, and the bottom of the foundation trenches is best supported by rock structures;

[0056] Wherein, the bottom side of the second construction foundation groove 4 is designed as an...

Abstract

The invention relates to the field of water conservancy project dam construction, and particularly discloses a water conservancy project dam foundation anti-seepage reinforcement construction technology which comprises the following steps that S1, a foundation trench is excavated in the ground below a gate of a dam; S2, the bottom of the foundation trench is tamped through mechanical equipment; S3, a fixing pile is driven into the bottom of the compacted foundation trench, and a plurality of tensile fixing plates are arranged on the circumferential surface of the fixing pile; S4, building formworks are built above the foundation trench according to the actual construction shape of the dam foundation at the gate, and the fixing piles and the tensile fixing plates are located in a construction cavity defined by the building formworks; S5, concrete and cement paste are injected into the construction cavity, and a gate dam foundation is formed; and S6, an anti-seepage sealing plate is fixedly installed at the joint of the gate dam foundation and the water area ground, and the back face of the anti-seepage sealing plate is filled with waterproof sealant and cement paste. Through the process, the problem that the bottom of the gate dam foundation is damaged due to the fact that the bottom is scoured by flood flow is solved.

Description

technical field [0001] The application relates to the field of construction of hydraulic engineering dams, in particular to an anti-seepage reinforcement construction technology for hydraulic engineering dam foundations. Background technique [0002] Water conservancy project dams refer to dikes and dams that intercept rivers and retain water, such as reservoirs and rivers, etc. The bottom of the water conservancy project dam or the location of the flood gate are equipped with dam foundations, and the dam foundations play a role in strengthening the support at the bottom of the dam. . [0003] Taking the dam foundation at the flood discharge gate as an example, the dam foundation bears a relatively large pressure of water flow, and the dam foundation is located at the bottom of the water area of ​​the flood discharge area, and the water pressure it bears is also very high. Therefore, the strength of the gate dam foundation itself and the connection between the gate dam found...
