Embodiment Construction

[0052] Such as Figure 1 to Figure 11 Shown, a kind of overflow gap concrete of the present invention enters the warehouse type roller compacted concrete dam construction method fast, comprises the following steps:

[0053] Step 1, construction of the foundation dam section: according to the design requirements of the foundation dam section 7, construct the foundation dam section 7 of the design elevation;

[0054] In this embodiment, the foundation dam section is provided with a water inlet hole, a diversion bottom hole and a discharge bottom hole.

[0055] In actual construction, roller compacted concrete dams are built between the two banks of rivers for flood control, water storage, water supply, and power generation.

[0056] Step 2: Construction of the transitional dam section, the process is as follows:

[0057] Step 201, determining the position of the overflow gap 1 at the top of the foundation dam section 7;

[0058] Step 202, constructing a conventional dam secti...

Abstract

The invention discloses a construction method of a roller-compacted concrete dam with overflowing notch concrete quickly put into storage, comprising the steps of: 1. constructing a foundation dam section; 2. constructing a transitional dam section; and 3. constructing a capping dam section. In the present invention, the conventional dam section and the transitional dam section RCC self-adaptive dam section are layered on the foundation dam section, and the transitional dam section RCC self-adaptive dam section is reconstructed to construct the transitional dam section RCC For the stepped dam section, the multi-layered RCC stepped dam section of the transitional dam section is connected successively to form a continuous construction channel for concrete transport vehicles. The gap is filled with roller compacted concrete into the warehouse, the construction period is short, the dam construction is convenient and fast, the construction efficiency is high, the construction quality is guaranteed, and the construction cost is saved.

Description

technical field [0001] The invention belongs to the technical field of roller-compacted concrete dam construction, and in particular relates to a method for constructing a roller-compacted concrete dam of a type of roller-compacted concrete dam whose concrete is quickly put into a storage gap. Background technique [0002] During the construction of the roller compacted concrete dam, due to the need for flood discharge during the flood season, usually in the design of the diversion design, a flow gap of a set size is reserved at the dam setting position and elevation, and the flow gap can be used for auxiliary drainage during the flood season flood. After the overflow gap completes the auxiliary diversion task, a permanent building needs to be built according to the design requirements. [0003] When the diversion task of the overflow gap dam section is completed and the construction resumes, a certain height difference has formed between the overflow gap dam section and th...
