Description

A kind of production method of drainage pipeline

Technical field

The invention belongs to technical field of buildings, and in particular to a kind of production method of drainage pipeline.

Background technique

China paid much attention to the protection to environmental ecology in recent years, more next to the renovation dynamics of pollution sources and ecological environment It is bigger, the exploitation for banning mine, stone field is constantly shut down, thus gives us traditional concrete to supply with cement products industry former material Very big difficulty should be brought, worse and worse, cost constantly marks liter to quality, increases the cost pressure of enterprise.Will so it consider Whether suitable material substitution is had, it is exactly a kind of substitution Novel environment-friendlymaterial material well to that haydite, and haydite is classified by raw material There are many kinds of it, utilizing from waste solids mainly has biological sludge haydite, lake bed-silt haydite, garbage ceramsites, flyash ceramic Grain etc..If the production of drainage pipeline can replace stone as the aggregate of concrete using haydite, it will realize waste utilization and reduce Production cost, but with the drainage pipeline of original production method production, there are haydites to float in concrete, product structure is uneven Disadvantage.

Summary of the invention

The purpose of the present invention is to propose to a kind of production methods of drainage pipeline, stone can be replaced as concrete using haydite Aggregate produces drainage pipeline, and makes properties of product up to standard.

The technical scheme of the present invention is realized as follows: a kind of production method of drainage pipeline, comprising the following steps:

1) haydite impregnates: picking up after dry haydite is impregnated 50-70 minutes into the water；

2) ingredient (parts by weight): 40-50 parts of cement, 70-80 parts of Machine-made Sand, the haydite 50- after the middle immersion of the step 1) 56 parts, 3-6 parts of polycarboxylate water-reducer, 13-16 parts of water；

3) it stirs: the cement, Machine-made Sand, haydite and the outer polycarboxylate water-reducer that match in the step 2) is put into blender Water that is interior and being put into half proportion, stirs 50-90 seconds, places into the other half water, continue stirring 90-150 seconds；

4) it forms: the material being stirred is put into the vibration moulding of core mould vibrating molding equipment.

More preferably, vibration moulding is formed by the way of vibrating when feeding intake in the step 4).

The present invention replaces stone to produce drainage pipeline as the aggregate of concrete using haydite, and haydite is evenly distributed on concrete In structure, do not occur floating and packing phenomenon, and bring it is following the utility model has the advantages that

1, lighter than normal discharge pipeline by 31.5%, concrete bulk density 1900kg/m³, transportation cost can be reduced；

2, Ceramsite Concrete impermeability is better than ordinary concrete, and haydite rough surface has certain water absorbing capacity, so haydite and water Caking ability ability between cement mortar is stronger, thus Ceramsite Concrete impermeability with higher；

3, Ceramsite Concrete construction adaptability is strong, easy for construction simple, and Ceramsite Concrete stirring, molding haydite do not float and separate, Presentation quality is preferable；

4, the environmental protection of waste solids utilizes, and the sludge and lake sludge baking ceramsite that can be generated with sewage plant reach waste Using, save the cost, the beneficial effect of environmental protection.

Specific embodiment

Below in conjunction with the embodiment of the present invention, technical scheme in the embodiment of the invention is clearly and completely described, Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based in the present invention Embodiment, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, all Belong to the scope of protection of the invention.

Embodiment 1

A kind of production method of drainage pipeline, comprising the following steps:

1) haydite impregnates: dry haydite being impregnated into the water and is picked up after sixty minutes；

2) ingredient (parts by weight): 45 parts of cement, 75 parts of Machine-made Sand, 55 parts of haydite after the middle immersion of step 1), polycarboxylic acids subtracts 4 parts of aqua, 14 parts of water；

3) it stirs: the cement, Machine-made Sand, haydite and the outer polycarboxylate water-reducer that match in the step 2) is put into blender Water that is interior and being put into half proportion, stirs 60 seconds, places into the other half water, continue stirring 120 seconds；

4) it forms: the material being stirred being put into the vibration moulding of core mould vibrating molding equipment, using what is vibrated when feeding intake Mode forms.

To the present embodiment drainage pipeline obtained carry out external load test: according to GB/T16752-2006 " concrete and Reinforced concrete sewer pipe test method " haydite concrete age is met 28 days, bore is 800 II grades of socket joint haydite coagulations of Ф Native pipe carries out external load test, is tested using line-of-sight course, crack occurs when being pressurized to 90% with 10% cracking load, using reading Digital display micro mirror surveys its fracture width, when loading to 110% pipe outer wall two sides of cracking load while crack occurs, micro- using logarithm Mirror measurement fracture width has reached 0.2mm, sees that crack later fracture width occurs and develops comparatively fast, as shown in Figure 1 through experimental phenomena.

The drainage pipeline haydite concrete test block section and normal concrete test block section of the present embodiment compare: such as Fig. 2 institute Show, haydite concrete coarse aggregate 100% is what haydite disconnected；As shown in figure 3, normal concrete 70% is disconnected from interface, 30% is disconnected from stone.

Conclusion: haydite substitutes stone mixing into dry concrete, and is applied to drainage pipeline using core mould vibrating molding New material, make its weight saving 30%, avoid haydite during production and float and gather materials existing in concrete As being evenly distributed on haydite in concrete structure, impermeability is better than normal concrete.

The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
