Description

Technical Field

[0001] The invention belongs to the field of building materials, in particular to a self-weight assembled non-bonded retaining wall brick and a prefabrication production process thereof. Background Art

[0002] At present, the commonly used retaining walls in engineering are generally in the form of rough stone masonry structure, brick structure, reinforced concrete structure, and corresponding anchor rod reinforced support structure, sprayed anchor structure and anchor cable structure, as well as pile structure combined with the latter two. However, for retaining walls lower than 2.0m, especially banks and soil slopes of water bodies such as rivers, lakes, ditches, canals and ponds, the traditional retaining wall structure isolates groundwater from the water body, thus hindering the good circulation channel of groundwater. At the same time, there are also defects such as the inability to vertically green the slopes, high labor intensity for workers, low construction efficiency, and environmental pollution. Summary of the invention

[0006] The third side includes a third straight side parallel to and corresponding to the first straight side, a first hypotenuse, and a second boss located between the third straight side and the first hypotenuse and protruding toward the first side; the second boss has the same specifications as the first boss and is opposite to each other; the end of the third straight side away from the second boss is connected to the fourth side end; the first hypotenuse is connected to the hypotenuse of the second boss away from the third straight side and is located in the same straight line direction, and the end of the first hypotenuse away from the second boss is connected to the second side end.

[0007] As a preferred technical solution of the present invention, the first side further includes a fourth straight side located on the same straight line as the first straight side or the second straight side, and a third boss protruding toward the third side; one end of the third boss is butted against the end of the second straight side away from the first boss, and the other end of the third boss is butted against one end of the fourth straight side; the end of the fourth straight side away from the third boss is connected to the second side end;

[0008] The third side also includes a fifth straight side and a sixth straight side parallel to the third straight side, and a fourth boss located between the fifth straight side and the sixth straight side and protruding toward the first side; the fifth straight side and the sixth straight side are located in the same straight line direction; the end of the fifth straight side away from the fourth boss is connected to the end of the first oblique side away from the second boss; the end of the sixth straight side away from the fourth boss is connected to the second side end.

[0009] As a preferred technical solution of the present invention, reinforcing ribs are provided inside the wall brick body, and the cross-sectional shape of the reinforcing ribs inside the wall brick body is the same as the cross-sectional shape of the wall brick body, and the cross-sectional shape and size of the reinforcing ribs are smaller than the cross-sectional shape and size of the wall brick body. The reinforcing ribs can be made of steel bars, bamboo bars and other non-metallic bars and fibers, or no bars are required, and only plain concrete is used.

[0010] As a preferred technical solution of the present invention, the angle between the hypotenuse of all bosses and the horizontal plane is 45°.

[0011] A self-weight assembled non-bonded retaining wall brick prefabrication production process comprises the following steps:

[0012] Step 1: Make a mold according to the drawings of retaining wall bricks. The mold making method can be one of casting, stamping and welding;

[0013] Step 2: Then, the reinforcement ribs of the wall brick body are made. The metal reinforcement ribs are welded to the reinforcement rib grid of the wall brick body by using a spot welding machine; the non-metallic reinforcement materials are made by binding or resin bonding;

[0014] Step 3: According to the mix ratio of cement: fly ash: shale ceramsite: shale ceramsite sand: water = 1:0.7:0.96:1.15:0.001, weigh each sub-item material in turn, and stir it by a forced mixer in a secondary feeding manner, and the slump is required to be 60mm-80mm;

[0015] Step 4: Then put it into the mold, vibrate, and press it. Remove the mold after 24 hours. It can be stacked after curing for 3 days, but the height should not exceed 2.0m. Continue to cure for 28 days and then it can be transported.

[0016] As a preferred technical solution of the present invention, the cement strength grade is the commonly used LC20; the particle size of shale ceramsite is ≤5mm, and the particle size of shale ceramsite is ≤15mm; the shale ceramsite and shale ceramsite can be completely or partially replaced by gravel, ordinary sand or recycled coarse and fine aggregates at equal volume ratios.

[0017] The stacking method of the self-weight assembled non-bonded retaining wall bricks of the present invention:

[0018] According to the construction organization design, the stacking design can be carried out first to achieve the optimal arrangement and reduce transportation waste, with a slight margin as the principle. During the specific construction, the bricks are stacked in order according to the number of layers. The basic principle is: the bottom layer is placed with a length of 500mm, and the first brick is After that, all others are The second layer is stacked with bricks of 400mm in length. The third layer is filled with bricks with a length of 300 mm. The first two bricks are All for Stacking.

[0019] If the bottom layer is filled with 500mm long bricks, the first brick is After that, all others are The second layer is filled with bricks with a length of 400 mm. The third layer is filled with bricks with a length of 300 mm. Later, press Stacking.

[0020] According to the above stacking principle, the interlayer staggered joints and layer-by-layer stacking can be achieved. After the three layers are stacked, the soil is immediately backfilled and compacted to complete a construction layer. Through the mutual engagement between the layers of bricks and the weight of the bricks and the backfill soil, a stable whole is formed. This cycle is repeated until the designed elevation is reached. According to the specific construction situation, other combinations can also be selected for stacking.

[0021] The beneficial effects of the self-weight assembled non-bonded retaining wall brick and the prefabrication production process thereof of the present invention are as follows:

[0022] 1. The self-weight assembled non-bonded retaining wall bricks of the present invention can be laid out in order like building blocks according to the construction requirements after the foundation is excavated, and the soil can be backfilled in time at each construction layer. Therefore, it has the significant advantages of low labor intensity for workers, high construction efficiency and no environmental pollution.

[0023] 2. The self-weight assembled non-bonded retaining wall bricks of the present invention have no mortar bonding between bricks and layers, so the gaps between them can ensure that the groundwater and the water body maintain a good water circulation channel, and under the effect of a long-term humid environment, a growth environment for microorganisms, animals and plants will naturally form vertical greening. When stacking, soil containing grass seeds can also be directly sown into the gaps, so that they will quickly germinate and grow under the infiltration of groundwater, playing the role of slope greening.

[0024] 3. The self-weight assembled non-bonded retaining wall bricks of the present invention have a maximum mass of 56.4 kg and a minimum mass of 14.6 kg for a single brick, which is convenient for workers to carry and construct, reduces the labor intensity of workers and is more conducive to improving construction efficiency.

[0025] 4. The self-weight assembled non-bonded retaining wall brick prefabrication production process of the present invention is made of shale ceramsite concrete or other light aggregate concrete. The components themselves have good permeability and water storage, adsorption and other functions, so they will also play a certain role in purifying water quality. In addition, if construction waste is used as recycled aggregate, it will open up a good new way for the resource application of construction waste. BRIEF DESCRIPTION OF THE DRAWINGS
