Description
Technical field
The present invention relates to a kind of anti-filter block utilizing cinder or slag to make and preparation method thereof, be applicable to side slope, roadbed and dam etc.
Background technology
In the design of building slope barricade engineering, by code requirement in barricade according to the size of the water yield, interval 2 ~ 3m, in plum blossom-shaped She Zhi ー row or arrange water vent more, its effect is used to discharge the underground water after wall in native rock, in order to reduce the active earth pressure of barricade, ensure the safety of retaining wall.Water vent is generally positioned at the middle and lower part of barricade, selects to fill the stronger filler of water-permeable after wall.Water vent and filler form the water exhaust system of barricade jointly.Under normal circumstances, be generally after wall, fill the thick sand filler of at least 0.5m as the draining inverted filter after wall, or after wall, pile up 0.50 × 0.50 × 0.50m anti-filter bag.The sand required thickness filled after wall is no less than 0.50m, by the impact of slope angle in construction, in the range of influence of a water vent, usually at least needs 3.0 ~ 6.0m
3sand, this will budget increase cost, particularly lacks area at sand, all the more so.In addition, sand is directly connected with water shoot side, has part sand and is directly taken away by wandering water, also there is a small amount of sand directly to sneak off in the water vent of flare, become the direct channel of stream soil, cause rolling earth behind retaining wall to be washed in a pan empty, slope retaining wall is out of shape, damage of even collapsing, and causes quality safety event.
Inside water drainage behind the wall pipe, anti-filter bag is piled up at scene, and the construction of this method is loaded down with trivial details, the easily deformable destruction of inclusion, and construction quality is difficult to control, and construction affects progress more slowly, and cost is also higher.
Summary of the invention
The object of this invention is to provide economical and practical, utilization of waste material, the anti-filter block utilizing cinder or slag to make of the soil-baffling structure draining of protection of the environment and method thereof.
The technical solution adopted for the present invention to solve the technical problems is:
The anti-filter block utilizing cinder or slag to make of the present invention, is made up of the raw material of following weight parts proportioning: cement 100 parts, cinder or slag 700-750 part.
A kind of preparation method utilizing cinder or slag to make anti-filter block of the present invention, is characterized in that:
A, batching: get cement 100 parts by weight, cinder or slag 700-750 part, wherein cinder or slag are broken into the clinker of 10 ~ 100mm, and the clinker content of < 10mm is less than 10 ~ 20%;
B, stirring: two kinds of raw materials after the mixing of step A batching add water and stir into mixture;
C, shaping: mixture step B obtained injects in mould, and with brick pressing machine under the pressure of 0.5 ~ 1.5Mpa, the centre be pressed into is with the square anti-filter block of patchhole;
D, by the anti-filter block demoulding after shaping, be 3 ~ 4 hours in the normal temperature environment time, cover watering maintenance after cement final set, curing time is 28-35 days, and the ultimate compression strength of obtained anti-filter block reaches 0.25 ~ 0.5Mpa.
Described anti-filter block is pressed into the anti-filter block of 500mm × 500mm × 500mm.
Advantage of the present invention is:
It is low that the anti-filter block obtained owing to have employed said ratio and preparation method of the present invention not only has density, and water-permeable, soil conservation and anti-blocking performance are good, also have certain intensity, its intensity can reach 0.25 ~ 0.5Mpa simultaneously, ensure that transport, construction and not broken damage in using; Raw materials cost is lower, and avoid slag and slag to the pollution of environment simultaneously, and need not carry out vapor cure, production technique is simple.
Use anti-filter block of the present invention to substitute inverted filter or the anti-filter bag of soil-baffling structure, jointly form the internal drainage system after side slope, barricade with water shoot.It can overcome Xian have technology Zhong ー not enough a bit, economical and practical, construction speed and construction quality can be improved, utilization of waste material, low-carbon environment-friendly, there is certain social benefit.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
As shown in Figure 1, Figure 2 and Figure 3, the anti-filter block utilizing cinder or slag to make of the present invention, be made up of the raw material of following weight parts proportioning: cement 100 parts, cinder or slag 700-750 part, wherein cinder or slag are broken into the clinker of 10 ~ 100mm, and the clinker content of < 10mm is less than 10 ~ 20%.
A kind of preparation method utilizing cinder or slag to make anti-filter block of the present invention, is characterized in that:
A, batching: get cement 100 parts by weight, cinder or slag 700-750 part, wherein cinder or slag are broken into the clinker of 10 ~ 100mm, and the clinker content of < 10mm is less than 10 ~ 20%;
Wherein: cinder is that coal or coke have cavernous scoriform thing after the molten, cooling of the rear formation of the middle burning of stove (or stove combustion chamber).
Ore dressing or the resistates after smelting are called
slag.
Cinder or slag, as aggregate, have more hole, space; These holes, space connectedness are good, permeable, have good water-permeable and water permeability; And the basic nonlinear type of these hole gaps, mostly in bending, vary in size, and there is the anti-worry performance preventing soil particle from being walked by water-band.
Due to the intensity of cement and kind more, in use, we carry out test proportioning according to the number of the intensity of cement, kind and aggregate and water ratio, mainly select ordinary Portland cement, intensity 42.5, that is: P042.5.
B, stirring: two kinds of raw materials after the mixing of step A batching add water and stir into mixture; Also as the stirring non-fine concrete, first cement and water can be stirred into grout, then add slag or slag stirs, can cement be saved like this.
C, shaping: mixture step B obtained injects in mould, and with brick pressing machine under the pressure of 0.5 ~ 1.5Mpa, the centre be pressed into is with the square anti-filter block 1 of patchhole.
D, by anti-filter block 1 demoulding after shaping, be 3 ~ 4 hours in the normal temperature environment time, cover watering maintenance after cement final set, curing time is 28 days-35 days, and the ultimate compression strength of obtained anti-filter block reaches 0.25 ~ 0.5Mpa.
Described anti-filter block 1 is pressed into the anti-filter block of 500mm × 500mm × 500mm.
During construction, first the earth filling tamping placed bottom anti-filter block 1 is reached design requirements, anti-filter block 1 is put
Put after retaining wall 2, and be connected with water vent 3 in the aperture 4 of the inner of water vent 3 insertion anti-filter block, namely form the water drainage system after barricade.
The function and effect of its anti-filter block 1 is infiltration filter soil, have certain water-permeable, its water-permeable: ensure wandering water by; Soil conservation: the sand grains after wall can be stoped to be taken away by wandering water; Anti-blocking property: the soil particle being less than silt level can by anti-filter block.
This anti-filter block is local test application in the retaining wall of Anshan iron and steel plant the Great Hermit Hill pelletizing plant engineering, respond well, has no barricade deformation and failure.
