Abstract
The utility model discloses a sand-blocking trench dike in a salt rock area, which comprises a dike with a regular trapezoid cross section and a trench arranged in parallel on one side of the dike, wherein the cross section of the trench is in an inverted trapezoid shape; the height of the dam is 3 meters, the width of the top surface of the dam is 3 meters, and the slope ratio of the two sides of the dam is 1: 1; the width of the bottom surface of the trench is 3 meters, the depth of the trench is 3 meters, and the slope rates of the two sides of the trench are 1: 1; one side slope of the dam is smoothly connected with one side slope of the trench, wherein the trench is arranged on the windward side of the main wind direction. The construction process is simple and convenient to operate, local materials can be obtained, regional resources in the salt rock area can be reasonably utilized according to local conditions, and engineering materials and construction cost are reduced.
Description
Technical Field
The utility model relates to a sand-blocking trench bank in a salt rock area.
Background
Sand is an atypical gas-solid two-phase flow, and sand particles are carried forward by wind. The gas in Xinjiang area of China is remarkable continental arid desert climate, and the main characteristic is that sand storm disasters easily occur due to frequent activities of wind and sand, so that wind erosion and sand burial are formed on railways and highways along the line, the travel of people and the local economic development are seriously influenced, and the problem to be solved urgently is formed. In the practice of sand control, various forms of sand control have been developed. According to the action principle, the sand prevention measures can be divided into four types of 'fixing, blocking, transporting and guiding', and a sand prevention system is formed by multiple combinations in practical application. The sand-blocking measures are generally positioned at the front edge of the wind sand, are important components of a sand-preventing system and have important wind-proof and sand-blocking functions. Newly building apocynum to the apocynum passing through dead sea and life forbidden area of the railway with the Qiang, and the line passes through the apocynum dry salt lake plain area, the earth surface is covered by salt shells, and the apocynum dry salt lake plain area has no vegetation, no human smoke and surface water, and presents salt desert landscape and wind erosion landform. The unfavorable geological phenomena along the line are wind sand which is mainly expressed by wind erosion, gobi wind sand flow and moving sand dunes. The plant sand prevention measures are difficult to implement, and the engineering sand prevention measures put higher requirements on the durability of the whole structure because the surface rock salt has strong corrosivity on common metal and concrete materials.
Disclosure of Invention
The utility model aims to provide a sand-blocking trench dam in a salt rock area, which is made of local materials, is economical and simple and is convenient to construct.
The technical scheme adopted by the utility model is that the sand blocking ditch dyke in the salt rock area comprises a dyke with a regular trapezoid cross section and a ditch arranged in parallel on one side of the dyke, wherein the cross section of the ditch is in an inverted trapezoid shape; the height of the dam is 3 meters, the width of the top surface of the dam is 3 meters, and the slope ratio of the two sides of the dam is 1: 1; the width of the bottom surface of the trench is 3 meters, the depth of the trench is 3 meters, and the slope rates of the two sides of the trench are 1: 1; one side slope of the dam is smoothly connected with one side slope of the trench, wherein the trench is arranged on the windward side of the main wind direction.
On the main wind direction side of a section needing sand blocking along the road, salt rocks are dug by an excavator, and the dug shape is that an inverted trapezoid with the lower bottom width of 3m, the height of 3m and the slope ratio of 1:1 on two sides forms a trench; crushing large-volume rock salt blocks into small-volume rock salt blocks by using a crushing machine; filling the crushed small-volume salt rock, wherein the filling shape is a regular trapezoid with the upper bottom width of 3m, the height of 3m and the slope rate of 1:1 at two sides, and simultaneously trimming the side slopes at two sides to form a dam; and saturated brine is sprayed to the side slopes on the two sides and the upper top surface, and when the water fully permeates the whole structure, the effect of compact salt cementation can be achieved, and the damage of wind and sand disasters can be resisted. The construction process is simple and convenient to operate, local materials can be obtained, regional resources in the salt rock area can be reasonably utilized according to local conditions, and engineering materials and construction cost are reduced. The method can prevent and control the sand storm disaster in the road building process in the salt rock area. The anti-wind and anti-sand composite material is arranged along the railway and the highway, has good economical efficiency, ensures the rapidness and convenience in construction, and can meet the requirements of wind prevention and sand prevention in a short time.

Detailed Description
As shown in fig. 1, the sand-blocking trench dyke in the salt rock area comprises a dyke 1 with a regular trapezoid cross section and a trench 2 arranged in parallel on one side of the dyke, wherein the cross section of the trench 2 is an inverted trapezoid; the height of the dam 1 is 3 meters, the width of the top surface of the dam 1 is 3 meters, and the slope ratio of the two sides of the dam is 1: 1; the width of the bottom surface of the trench is 3 meters, the depth of the trench is 3 meters, and the slope rates of the two sides of the trench are 1: 1; one side slope of the dam 1 is smoothly connected with one side slope of the trench 2, wherein the trench 2 is arranged on the windward side of the main wind direction. The trench 2 is firstly dug along the wind direction when the wind blows from any direction, and then the dam 1 is built, wherein the trench 2 and the dam 1 are vertical to the wind direction.
