Problems solved by technology

[0003] In the actual use process, because the pipe culvert is usually buried underground, it will be corroded by various acidic or alkaline liquids. If it is in this environment for a long time, the mechanical strength of the pipe culvert will plummet, which will lead to the occurrence of underground pipe culverts. Seepage

preparation example Construction

[0013] The invention provides a method for preparing an underground pipe culvert with high stability, the preparation method comprising:

[0014] 1) In the presence of protective gas, calcining plant straw, diatomaceous earth, argyroite and potassium oxyfluoroniobate to obtain a calcined product;

[0015] 2) In the presence of ultraviolet rays, heating and mixing asphalt, polypropylene fibers, rubber particles, sodium gluconate and calcined products to obtain activated products;

[0016] 3) Sand, cement, fly ash, water and activation products are mixed, poured and maintained to produce underground pipe culverts with high stability.

[0017] In step 1) of the present invention, the specific type of protective gas can be selected in a wide range, but considering cost and protective effect, preferably, in step 1), the protective gas is selected from nitrogen, argon and helium One or more of the air.

[0018] In step 1) of the present invention, the specific type of protective g...

Embodiment 1

[0029] 1) In the presence of argon, calcinate plant straw (rice straw), diatomaceous earth, argyroite and potassium oxyfluoroniobate at 950°C for 22 hours at a weight ratio of 100:25:9:8 A calcined product is obtained;

[0030] 2) In the presence of ultraviolet rays with a wavelength of 150nm, mix asphalt, polypropylene fibers, rubber particles, sodium gluconate and calcined products at 210°C for 7 hours at a weight ratio of 100:7:27:12:22 to obtain activation product;

[0031] 3) Sand, cement, fly ash, water and activated product were mixed according to the weight ratio of 100:110:240:380:70, poured and maintained at 32°C for 10 days (watering twice a day) to obtain a High stability underground pipe culvert A1.

Embodiment 2

[0033] 1) In the presence of nitrogen, calcinate plant stalks (corn stalks), diatomaceous earth, argyroite and potassium oxyfluoroniobate at 900°C for 20 hours at a weight ratio of 100:21:5:3 to produce Get calcined products;

[0034] 2) In the presence of ultraviolet rays with a wavelength of 100nm, mix asphalt, polypropylene fibers, rubber particles, sodium gluconate and calcined products at a weight ratio of 100:2:25:9:17 at 200°C for 5 hours to obtain activation product;

[0035] 3) Sand, cement, fly ash, water and activated product were mixed according to the weight ratio of 100:100:200:300:60, poured and maintained at 30°C for 7 days (watering twice a day) to obtain a High stability underground pipe culvert A2.

Abstract

The invention discloses a high-stability underground pipe culvert and a preparing method thereof. The preparing method comprises the steps of 1, calcinating plant straw, kieselguhr, argyrodite and potassium fluoxyniobate in the presence of shielding gas to obtain a calcination product; 2, heating and mixing pitch, polypropylene fiber, rubber particles, sodium gluconate and the calcination product in the presence of ultraviolet rays to obtain an activation product; 3, mixing, pouring and curing sand, cement, coal ash, water and the activation product to obtain the high-stability underground pipe culvert. The underground pipe culvert prepared with the method has excellent stability.

Description

technical field [0001] The invention relates to an underground pipe culvert, in particular to an underground pipe culvert with high stability and a preparation method thereof. Background technique [0002] Underground pipes and culverts refer to water pipes buried in the ground, which can be used as waterways below the ground level. Pipe culverts are structures in highway and railway engineering, and generally refer to round pipe culverts, which are culverts made of circular pipes made of reinforced concrete. [0003] In the actual use process, because the pipe culvert is usually buried underground, it will be corroded by various acidic or alkaline liquids. If it is in this environment for a long time, the mechanical strength of the pipe culvert will plummet, which will lead to the occurrence of underground pipe culverts. Seepage. Contents of the invention [0004] The object of the present invention is to provide an underground pipe culvert with high stability and a pre...
