Problems solved by technology

However, the slope protection bricks cannot effectively resist the external force in the horizontal direction. Once serious precipitation, slope vibration and other conditions occur, they are very vulnerable to the impact of the slope, resulting in large-scale landslides.

Embodiment 1

[0022] Self-locking slope protection bricks are made of the following raw materials by weight: 46.5 parts of crushed stone, 23 parts of cement, 8.5 parts of silicomanganese slag, 1.6 parts of modifier, 0.8 parts of polycarboxylic acid water reducer, and ethylenediamine tetramethylidene 1.3 parts of sodium phosphonate and 5 parts of water. The modifier consists of potassium hydroxyethylene diphosphonate, polyamino polyether methylene phosphonic acid, sodium ethylenediamine tetramethylene phosphonate and sodium tolyltriazole according to 1:2.5:0.3 : 0.9 weight ratio mixing system. The particle size of the crushed stone is 5-25mm.

[0023] When making, first mix the silico-manganese slag and modifier uniformly to obtain modified silico-manganese slag; then mix the modified silico-manganese slag with the rest of the raw materials uniformly to obtain a mixture; finally place the mixture in the mold to vibrate and pressurize Molding, the pressure is 8MPa, and air dry after demolding....

Embodiment 2

[0025] Self-locking slope protection brick, made of the following raw materials by weight: 40 parts of gravel, 25 parts of cement, 5 parts of silico-manganese slag, 2 parts of modifier, 0.5 parts of polycarboxylic acid water reducing agent, ethylenediamine tetramethylene 2 parts of sodium phosphonate and 2.8 parts of water. The modifier consists of potassium hydroxyethylene diphosphonate, polyamino polyether methylene phosphonic acid, sodium ethylenediamine tetramethylene phosphonate and sodium tolyltriazole according to 1:3:0.1 : The weight ratio of 1.2 is mixed. The particle size of the crushed stone is 5-25mm.

[0026] When making, first mix the silico-manganese slag and modifier uniformly to obtain modified silico-manganese slag; then mix the modified silico-manganese slag with the rest of the raw materials uniformly to obtain a mixture; finally place the mixture in the mold to vibrate and pressurize Molding, the pressure is 8MPa, and air dry after demolding.

Embodiment 3

[0028] Self-locking slope protection brick, made of the following raw materials by weight: 50 parts of crushed stone, 20 parts of cement, 13 parts of silicomanganese slag, 1 part of modifier, 1 part of polycarboxylic acid water reducing agent, ethylenediamine tetramethylidene 1 part of sodium phosphonate and 6 parts of water. The modifier consists of potassium hydroxyethylene diphosphonate, polyamino polyether methylene phosphonic acid, sodium ethylenediamine tetramethylene phosphonate and sodium tolyltriazole according to 1:2:0.4 : 0.6 weight ratio mixing system. The particle size of the crushed stone is 5-25mm.

[0029] When making, first mix the silico-manganese slag and modifier uniformly to obtain modified silico-manganese slag; then mix the modified silico-manganese slag with the rest of the raw materials uniformly to obtain a mixture; finally place the mixture in the mold to vibrate and pressurize Molding, the pressure is 9MPa, and it can be air-dried after demolding.

Abstract

The invention relates to a self-locking slope protection brick. The self-locking slope protection brick comprises a bottom plate and lock hooks symmetrically arranged at the two ends of the bottom plate. The cross sections of the lock hooks are of right trapezoid structures. The short bottom edges of the right trapezoid structures are fixedly connected with the bottom plate, and an inserting slotis formed between each long side edge and the bottom plate. The center of the bottom plate is further provided with a protruding baffle, and the baffle and slots in the two sides form spaces for storing lock hooks of another self-locking slope-protection brick in a matched manner correspondingly. The self-locking slope protection brick is fabricated by the raw materials of, in weight, 40-50 partsof broken stones, 20-25 parts of cement, 5-13 parts of siliconmanganese slag, 1-2 parts of a modifying agent, 0.5-1 part of a polycarboxylate water-reducer, 1-2 parts of ethylene diamine tetra methylene phosphonic sodium and 2.8-6 parts of water. The self-locking slope protection brick is simple and reasonable in structure, convenient and fast to prepare, mutual self-locking can be achieved, impact of a slope body can also be resisted effectively, and large-area landslide is avoided.

Description

Technical field [0001] The invention relates to the technical field of building materials, and relates to a self-locking slope protection brick. Background technique [0002] Slope protection brick is a kind of brick with a certain specific shape built on slopes, river banks and other places. The use of slope protection bricks can effectively prevent soil erosion and help protect the environment on both sides of roads, railways and rivers. In the prior art, such as CN203049594U, a slope protection brick is disclosed. The brick body is hollow. The upper and lower ends of the brick body are provided with slots corresponding to each other. Locking hooks are arranged on both sides of the slot. The slots and the locking hooks form a self-locking structure. . The slope protection brick and its deformation disclosed in this patent are the most common slope protection brick on the market. The slope protection brick has good self-locking effect, simple structure and convenient processi...
