Abstract
The invention discloses a dam face of a retaining dam. The dam face consists of a rectangular steel plate and concrete, wherein the steel plate faces one side with a high water level, the back side of the steel plate is provided with the concrete, reinforced ribs are arranged in the concrete, and the concrete comprises the following components in parts by weight: 10-30 parts of cement, 50-100 parts of yellow sand, 10-30 parts of cementing material, 0.2-0.6 part of antifreezing agent, 0.1-0.3 part of swelling agent and 0.1-0.3 part of water reducing agent. A steel plate and concrete combination mode is adopted, and the reinforced ribs are additionally arranged in the concrete, so that the strength of the dam face is effectively enhanced; the antifreezing agent is added in the concrete, so that the anti-freezing property of the dam face is effectively improved; the cementing agent is added into the concrete, so that the concrete can be prevented from a false set.
Description
Technical field
The present invention relates to the dam facing structure in a kind of hydraulic engineering, particularly relate to a kind of check dam dam facing.
Background technology
Concrete is adopted to make dam facing, have that intensity is high, easy construction, stability is good, excellent in durability, maintenance cost are low, be widely used in construction work, but the dam facing structure of concreting is when constructing winter, because winter temperature is lower, can easily cause bursting by freezing phenomenon or false set.
Summary of the invention
Problem to be solved by this invention is: provide a kind of check dam dam facing, and described check dam dam facing adopts concrete to make, and in the season that temperature is low, construction there will not be bursting by freezing or false set.
In order to solve the problem, technical scheme of the present invention is a kind of check dam dam facing, dam facing is movably connected on the horizontal base below dam facing, comprise rectangle steel plate and concrete, steel plate surface is towards the high side of water level, dorsal part is provided with concrete, and described concrete comprises the component of following weight proportioning: 10 ~ 30 parts of cement, 50 ~ 100 parts of yellow sands, 10 ~ 30 parts of cementitious material, 0.2 ~ 0.6 part of antifreezing agent, 0.1 ~ 0.3 part of expansion agent, 0.1 ~ 0.3 part of water reducing agent composition.
Further, described cementitious material comprises gypsum, silicon ash, breeze.
Further, the mass ratio of described cementitious material constituent gypsum, silicon ash, breeze is 1:2:3.
Further, described cementitious material also comprises stone, and the particle diameter of described stone is 5 ~ 10mm, and the quality of described stone is the same with powdered ore quality.
Further, described antifreezing agent is the compound early strength antifreezing agent of no chlorine and low alkali.
Further, described expansion agent is calcium sulphoaluminate type cement expansive material.
Further, described water reducing agent is polycarboxylic acid early-strength water reducing agent.
Beneficial effect of the present invention:
1. adopt the mode that steel plate is combined with concrete, and add reinforcing rib in concrete, effectively raise dam facing intensity.
2. in concrete, with the addition of antifreezing agent, the effective resistance to frost increasing dam facing.
3. in concrete, with the addition of gelling agent, can prevent concrete from occurring false set.
Detailed description of the invention
A kind of check dam dam facing, dam facing is actively installed on the horizontal base below dam facing, dam facing comprises rectangle steel plate and concrete, steel plate surface is towards the high side of water level, dorsal part is provided with concrete, in concrete, be provided with reinforcing rib, concrete comprises the component of following weight proportioning: 10kg cement, 50kg part yellow sand, 0.1kg gypsum, 2kg silicon ash, 3.25kg breeze, 3.25kg stone, 0.2kg antifreezing agent, 0.1kg expansion agent, 0.1kg water reducing agent composition.
Adopt the mode that steel plate is combined with concrete, and add reinforcing rib in concrete, effectively raise dam facing intensity.
In order to ensure its good freezing protection effect, in concrete, with the addition of the compound early strength antifreezing agent of no chlorine and low alkali, calcium sulphoaluminate type cement expansive material, polycarboxylic acid early-strength water reducing agent; Adopt the compound early strength antifreezing agent of no chlorine and low alkali can prevent moisture in material from freezing at low temperatures; Adopt calcium sulphoaluminate type cement expansive material not containing sodium salt, should not alkali-aggregate reaction in concrete be caused.And durability is good, expansion character is stablized, and intensity continuous rises, and substantially increases the anti-cracking waterproof ability of concrete structure; Adopt polycarboxylic acid early-strength water reducing agent can cooperatively interact with the compound early strength antifreezing agent of no chlorine and low alkali, make antifreezing effect better.
Adopt the cementitious material combined by gypsum, silicon ash, breeze, stone, and the particle diameter controlling stone is 5mm ~ 10mm, is convenient to mixed and stirs construction; Adopt above-mentioned cementitious material can effectively alleviate the false set occurred in casting process, also improve the bulk strength of dam facing simultaneously.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
