Problems solved by technology

Lime and cement are mostly used in the existing cement. Although the strength required by the design can be achieved, its water resistance, anti-seepage, and corrosion resistance are poor, the curing is slow, the early strength is low, and it needs to consume a lot of cement resources.
There are also multi-model high-strength and high water-resistant soil consolidation agents that use sand as fine aggregate and stones as coarse aggregate, which can be applied to different consolidation objects. Although the effect is good, the production cost is high
[0003] In the Huayuankou section of the Yellow River Basin, the water flow is slow, and mud and sand are deposited on the riverbed, causing the riverbed to rise and affecting flood control safety

Embodiment 1

[0016] Example 1 Preparation of hexagonal hollow brick for ecological slope protection

[0017] Ecological slope protection hexagonal hollow bricks are mostly used as materials for high-speed railways, highways and water conservancy dams, and the roots of plants growing in the hollow parts of the bricks stabilize the slope. The specific method is:

[0018] 1. Preparation of consolidating agent

[0019] The first step is to test the muddy silt and fine sand raw materials obtained from the river bed to determine that the quartz content is 55% and the clay particle content is 13%, which proves that the muddy silt and fine sand raw materials meet the requirements for use; then the muddy silt and fine sand The raw materials are preheated and dried in the drying furnace, then sent to the calciner, calcined at a high temperature of 1050~1150°C for two hours, and then cooled to room temperature within 1 hour, then sent to a grinder to grind to 200~300 mesh fine powder for later use ...

Embodiment 2

[0023] Example 2 Preparation of drain diversion groove

[0024] Drain diversion grooves are suitable for drainage ditches in embankment projects and river ecological management projects, and are mainly used to discharge surface water such as rainwater.

[0025] 1. Preparation of consolidating agent

[0026] The first step is to test the muddy silt and fine sand raw materials obtained from the river bed to determine that the quartz content is 50% and the clay particle content is 11%, which proves that the muddy silt and fine sand raw materials meet the requirements for use; then the muddy silt and fine sand The raw materials are preheated and dried in the drying furnace, then sent to the calciner, calcined at a high temperature of 1050~1150°C for two hours, and then cooled to room temperature within 1 hour, then sent to a grinder to grind to 200~300 mesh fine powder for later use ;

[0027] In the second step, the calcined argillaceous silt fine sand fine powder and mineral p...

Embodiment 3

[0030] Example 3 Preparation of ecological slope protection hexagonal block

[0031] The ecological slope protection hexagonal block is suitable for the protection of the embankment of the river ecological management project, and enhances the flood control capacity of the embankment.

[0032] 1. Preparation of consolidating agent

[0033] The first step is to test the muddy silt and fine sand raw materials obtained from the river bed first, and determine that the quartz content is 48% and the clay particle content is 17%, which proves that the muddy silt fine sand raw materials meet the requirements for use; then the muddy silt fine sand The raw materials are preheated and dried in the drying furnace, then sent to the calciner, calcined at a high temperature of 1050~1150°C for two hours, and then cooled to room temperature within 1 hour, then sent to a grinder to grind to 200~300 mesh fine powder for later use ;

Abstract

The invention discloses a preparing method for a sandy soil solidification agent. The preparing method includes the steps that argillaceous silty-fine sand is preheated and dried to be put into a calcining furnace, and the obtained product is calcined for 2 hours at the high temperature of 1,050 DEG C to 1,150 DEG C, then is rapidly cooled (time when the obtained product is cooled to the room temperature is not more than 1 hour), and then is ground to 200 mesh to 300 mesh ready for use; the prepared calcined-argillaceous-silty-fine-sand fine powder, mineral powder and cement are weighed according to the weight percentage of the calcined-argillaceous-silty-fine-sand fine powder to the mineral powder to the cement of (70%-80%):(5%-10%):(10%-25%) to be mixed evenly, and the sandy-soil-solidification-agent finished product is obtained. The preparing method for the sandy soil solidification agent has the advantages that a raw material can be obtained locally, the transportation cost is saved, the argillaceous silty-fine sand of the middle and lower reaches of the Yellow River is reasonably used, and sedimentation of the middle and lower reaches is also be slowed down; the preparing method is simple, green, capable of saving energy and environmentally friendly; the solidification agent prepared with the method and medium fine sand in sedimentation mud sand can also be blended in proportion to be made into a prefabricated product, and good social benefits and economic benefits can be generated through comprehensive utilization of the raw material.

Description

technical field [0001] The invention relates to the technical fields of water conservancy engineering and building materials, in particular to a method for manufacturing sandy soil consolidation agent. Background technique [0002] Sand consolidation agent is widely used in cave filling and reinforcement in mining areas, building foundation pit filling, dam body and slope protection reinforcement filling in water conservancy projects, freight yard foundation, road foundation and other infrastructure construction. Lime and cement are mostly used in existing cements. Although they can achieve the strength required by the design, they have poor water resistance, anti-seepage, and corrosion resistance, slow curing, low early strength, and consume a large amount of cement resources. There are also multi-model high-strength and high water-resistant soil consolidation agents that use sand as fine aggregate and stones as coarse aggregate, which are suitable for different consolidati...
