Embodiment 1

[0051] Such as Figure 1-13 Shown a kind of loess hilly geomorphic area steep slope condition silted land terrace economic forest construction method, comprises the following steps:

[0052] Step 1: prefabricated component one, component one is the reinforced concrete pile 5 that fixed pile is used;

[0053] Step 2: Prefabricate component 2. The component 2 is formed by putting formula loess carrier 6 into mold box 4, formula loess carrier 6 is filled with formula loess, and the formula loess carrier 6 is sealed after compaction.

[0054] Step 3: Assemble and arrange component one and component two;

[0055] Ramming component one prefabricated in step one on the original slope 9, placing prefabricated component two into the gap between prefabricated component one;

[0056] Step 4: forming the terraced alluvial soil layer 8;

[0057] The installed device is assembled in step 3 to intercept the soil, silt and organic matter carried by the rainwater, and form the silted soil lay...

Embodiment 2

[0078] Such as Figure 1-3 and Figure 5-13 As shown, compared with Embodiment 1, the difference of this embodiment is that the upper section of the prefabricated component one is a cuboid and the lower section is a cone, and a hooking device is fixedly arranged on one side of the upper cuboid, and the prefabricated component The inside of one is provided with a support frame.

[0079] Preferably, the prefabricated component one is made of fine stone concrete 2 , the hooking device in the prefabricated component one is a steel bar prefabricated hook 1 , and the supporting framework inside the prefabricated component one is a threaded steel bar 3 .

[0080] In actual application, the lower section of the prefabricated component is a cone to facilitate ramming into the loess slope, and the upper section is a cuboid to facilitate overall installation and installation. The setting of the hook device makes the placement of the square loess load 6 more stable. The interior of the p...

Embodiment 3

[0082] Such as figure 1 , Figure 4-7 As shown, compared with Embodiment 1, the difference of this embodiment is that the inner dimensions of the mold box 4 are 75 cm, 30 cm, and 90 cm in length, width, and height, respectively, and the upper end of the mold box 4 is open.

[0083] It is preferred that described mold case 4 is custom-made wooden with 2cm thick plank

[0084] Preferably, the formula loess load placed in the wooden mold is a 75cm*105cm national standard sack.

[0085] During concrete implementation, 75cm*105cm national standard sack is placed in wooden mold 4, and formula loess is placed wherein to tamp in national standard sack as load-carrying object, and sews up with thread, preferably sews up with thick twine.

[0086] The present invention adopts this solution, well realizes the functions of the present invention, and is economical and practical in terms of materials.

Abstract

The invention relates to the fields of ecological environment improvement and engineering construction, in particular to a method for constructing economic forests on slit ground terraced fields undera steep slope condition in a loess geomorphy loess hill landform area. The method comprises the following seven steps: I, prefabricating a component I; II, prefabricating a component II; III, assembling the component I and the component II; IV, molding a terraced field base layer; V, laying a formula soil layer; VI, planting economic frosts; VII, laying a covering article. Aiming at a steep slopearea with the slope of 26-40 degrees in loess geomorphy of a northern Shaanxi loess plateau hilly and gully region, the invention provides a novel transformation technique which is simple and convenient in construction, low in cost and good in vegetation applicability, the purposes of water and soil loss prevention and treatment and land optimization utilization are achieved, capacity-increase adjustment on water and soil loss steep slope type 'soil water reservoirs' is achieved, ecological environments are recovered, and agricultural production efficiency is improved.

Description

technical field [0001] The invention relates to the fields of ecological environment engineering and engineering construction, in particular to a method for constructing economic forests in silted terraced fields under steep slope conditions in loess hilly landform areas. Background technique [0002] The Loess Plateau is the largest loess accumulation area in the world, with a total area of ​​640,000 square kilometers, spanning the seven provinces of Qinghai, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, and Henan. It is one of the birthplaces of ancient Chinese civilization. [0003] The Shaanxi Loess Plateau covers an area of ​​about 89,000 square kilometers, accounting for 43.2% of the total area of ​​Shaanxi Province. The main landform of the Loess Plateau in northern Shaanxi is the hilly and gully area of ​​the Loess Plateau, which is covered with thick layers of loess, with a thickness of 50-80 meters and a maximum thickness of 150-180 meters. The main body of the...
