Abstract

The utility model discloses an H-shaped plain concrete brick. The H-shaped plain concrete brick is wholly rectangular, the cross section of the rectangle is H-shaped, and the whole H-shaped plain concrete brick is inclined. The utility model further discloses a soil-blocking wall bricked by the H-shaped plain concrete bricks, and the soil-blocking wall further comprises top-pressing bricks and bottom bricks. The shape of the section of the H-shaped plain concrete brick is modified, so that after a main wall body is bricked by the H-shaped plain concrete bricks, an upper embedding foot and a lower embedding foot are better embedded and combined, sliding is prevented, and shearing resistance is improved. Due to an inclined matching surface, the inclination of the wall body is more reasonable, and stress is effectively dispersed. The H-shaped plain concrete brick is simple in structure, easy to manufacture, low in cost, fast in production, and capable of being widely applied to the soil-blocking wall of geotechnical engineering and embankment construction of hydraulic engineering.

Step 6: the leveling of retaining wall end face and green grass.
This programme has following advantage:
1, takes full advantage of the shear resistance principle of the soil body self, particularly to the utilization of compacted backfill shallow-layer cohesion, saved heavy wall-retaining structure, namely saved investment.
2, building block is tiltedly " H " shape, form facing upward of 1:0.2, the moving safety factor of antiskid has been improved 0.15 again, in addition the enhancing of toe rubble and plain concrete bed course antagonism slip and anti-shear ability, further improved safety factor again, ensured that the moving safety factor of retaining wall antiskid satisfies code requirement.
3, be different from other building blocks or panel reinforced earth retaining wall, this programme is orientated small-sized retaining wall as at the body of wall characteristic, and reinforcement materials such as geo-grid need be set, and therefore, excavation and backfill width reduce significantly.
4, the deadweight of this programme retaining wall is about 1/2~1/3 of close height stone masonry retaining wall, barricade is light, low to the ground requirement for bearing capacity, characteristic value of foundation bearing capacity can meet the demands greater than 80kPa, except mud, muddy soft soil layer, general soil layer does not need specially treated to meet the demands, and has further saved investment.
5, this programme retaining wall utilizes geotextiles, rubble and blockhouse slit, forms complete smooth suitable drainage system, has effectively reduced water pressure behind the wall, does not need to arrange separately spilled water hole again.
6, the surface area of the plain concrete building block of H type retaining wall is big, the surface area of single standard block is 0.67 ㎡, is example with the high retaining wall of 2.5m, and surface area reaches 20.9 ㎡/linear meter(lin.m.), its area is 4 times of traditional retaining wall, for microorganism and small-sized animals and plants provide the habitat.
7, block wall is removed or during displacement, building block is reusable.
8, the prefabricated plain concrete building block of H type is for porous ecological brick material, shape succinctly, easily prefabricated, block is fine and close, intensity is high, good endurance.
9, block wall elevation appearance lines are clean and tidy, and are uneven, assemble like the rectangular slab of stone and long brick to form.
When 10, the building block retaining wall is used for water shore protection space, shore, is beneficial to persons falling in water and saves oneself.
More than preferred embodiments of the present utility model is specified, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite of the utility model spirit, the modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
