Anti-seep underground pipe culvert and preparation method thereof

Abstract

The invention discloses an anti-seep underground pipe culvert. The anti-seep underground pipe culvert is prepared from cement, gravels, river sands, pulverized fuel ash, dicumyl peroxide, polyisobutene, ethyl carbamate, hydroxytrimethylsilane, water, an air entraining agent and water reducer. The invention further discloses a method for preparing the anti-seep underground pipe culvert. The method comprises the following steps of (1) mixing the cement, the gravels, the river sands, the pulverized fuel ash, the dicumyl peroxide, the polyisobutene, the ethyl carbamate, the hydroxytrimethylsilane, the air entraining agent and the water reducer to prepare a mixture M1; (2) pouring the mixture M1 into a reinforcement cage to form a pipe culvert blank body; and (3) maintaining the pipe culvert blank body to obtain the anti-seep underground pipe culvert. The anti-seep underground pipe culvert prepared by the method has an excellent water seepage prevention function, and has relatively high compressive strength and splitting tensile strength.

Description

technical field [0001] The invention relates to the field of cement pipe preparation, in particular to an antibacterial underground pipe culvert 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] After the concrete is poured, there are some voids inside. Under the influence of long-term water pressure, the internal voids of the concrete will increase, and even cracks will appear. Existence, therefore, have very big requirement to the anti-seepage performance of concrete, the concrete waterproof performance prepared in the prior art is very poor, may crack or even collapse danger when subjected to water pressure for a long time.

Problems solved by technology

[0003] After the concrete is poured, there are some voids inside. Under the influence of long-term water pressure, the internal voids of the concrete will increase, and even cracks will appear. Therefore, there is a great demand for the anti-seepage performance of concrete. The waterproof performance of the concrete prepared in the prior art is very poor, and the danger of cracking or even collapse may occur when it is subjected to water pressure for a long time
