Abstract
The invention discloses a novel electric transmission line foundation poured by coal gangue aggregate concrete, and relates to the technical field of high-tension transmission line foundations. The novel electric transmission line foundation comprises a concrete foundation which is poured by coal gangue concrete with the C25 strength grade, and the coal gangue concrete is prepared by water, concrete, sand, crushed stones, coal gangue and a water reducing agent according to the mix proportion of 1: 2.36: 2.98:2.83: 3.05: 0.01. According to the novel electric transmission line foundation, stones are convenient to take, the engineering construction period is effectively shortened, the cost is low, the cost of concrete coarse aggregate materials can be saved by about 40% by replacing ordinary crushed stones with the coal gangue, the construction cost is effectively reduced, and the novel electric transmission line foundation is environment-friendly and has good environmental and social effects.
Description
Technical field:
Patent of the present invention relates to ultra-high-tension power transmission line foundation works technical field.
Background technology:
The concrete coarse aggregate that existing transmission line foundation uses is generally common rubble, but in the time that engineering construction region belongs to Plain landforms or producing region, colliery, affect the construction speed of transmission line foundation because common rubble is difficult to obtain, and carry out rubble from outer transport stone and cause the problem that construction cost significantly rises to be arisen at the historic moment.
Patent of invention content:
The object of patent of the present invention is to provide a kind of transmission line foundation that can effectively solve the employing coal gangue aggregate concrete cast of Plain landforms or producing region, colliery getting stone difficulty, a rubble difficult problem on the high side.
Existing in order to solve in background technology, the present invention is by the following technical solutions: it comprises concrete foundation, and described concrete foundation is by according to water: cement: sand: rubble: coal gangue: water reducer=1: 2.36: 2.98: 2.83: the coal gangue concrete cast that the proportioning of 3.05: 0.01 makes C25 strength grade forms.
The present invention has the following advantages compared with normal concrete transmission line foundation:
1, get stone convenient, effectively shorten the engineering construction cycle;
2, cheap, use coal gangue to substitute common rubble and can save nearly 40% concrete coarse aggregate Master Cost, effectively reduce construction costs;
3, environmental friendliness, has good environment and social effect.
Embodiment:
Take North Huaihe River Area of Anhui Province as example, coal gangue discarded producing region, colliery, Northern Area of Huaihe River is first carried out to physics and chemistry performance test, recording main chemical compositions is table 1:
Table 1
| Oxide compound | SiO 2 | Al 2O 3 | Fe 2O 3 | CaO | MgO | SO 3 | Loss on ignition |
| Massfraction/% | 62.16 | 16.34 | 5.32 | 4.11 | 2.78 | 0.43 | 0.79 |
Recording Main physical and mechanical technology index is table 2:
Table 2
Then by above-mentioned coal gangue according to water: cement: sand: rubble: coal gangue: water reducer=1: 2.36: 2.98: 2.83: the proportioning of 3.05: 0.01 makes C25 strength grade coal gangue coarse aggregate concrete, wherein the alternative rubble of coal gangue is 51.9% as the best substitution rate of coarse aggregate, after following relevant code regulation the aspects such as this concrete workability, intensity, distortion and weather resistance are detected, concrete casting is formed to transmission line foundation.
Patent of the present invention adopts coal gangue aggregate to replace common rubble, under the prerequisite of guaranteeing engineering safety, solved mining area and get a difficult problem for stone difficulty, has considerable economic benefit, long-range society and environmental effect simultaneously.
Claims (3)
