Abstract
The invention discloses grouting mixed cement slurry and a pipe structure. The grouting mixed cement slurry comprises the following components in parts by weight: 700 parts of water, 150 parts of bentonite, 75 parts of 425# general silicate cement, 74 parts of talcum powder, 0.5 part of polyacrylamide additive and 0.5 part of carboxymethylcellulose additive. The pipe structure comprises a PE core pipe, an outer pipe sleeve and a cement slurry filling layer, wherein the PE core pipe is inserted in the outer pipe sleeve; and the grouting mixed cement slurry according to claim 1 is cast in the cement slurry filling layer formed between the PE core pipe and the outer pipe sleeve. The grouting mixed cement slurry and the pipe structure can preferably satisfy the mounting, use and maintenance requirements of the PE core pipe. The mixed cement slurry is high in fluidity, and is convenient to be installed; and a cured coagulation adopts a crisp block structure, and has the advantages of proper hardness, good fixing effect, capability of easy stripping and convenience for use and maintenance.
Description
Technical field
The present invention relates to the technical field of injecting paste material and pipeline configuration, particularly relate to a kind of grouting blended cement slurries and pipeline configuration.
Background technique
Existing PE(polyethylene) insert in sleeve pipe in core pipe, between sleeve pipe and PE core pipe, adopt cement grout to fill, the coagulative hardness level of cement grout can cause larger impact to the mounting, commissioning and maintenance of PE core pipe.Cement grout is coagulative too hard, and PE core pipe is easily aging, and later period maintenance construction inconvenience.Cement grout is coagulative too soft, and the fixed effect of PE core pipe in sleeve pipe is poor.
Therefore, the applicant is devoted to develop a kind of grouting blended cement slurries and pipeline configuration, meets PE installation of core pipe, operation and maintenance demand preferably.
Summary of the invention
Because the above-mentioned deficiency of prior art, the present invention proposes a kind ofly to meet PE installation of core pipe, the grouting blended cement slurries of operation and maintenance demand and pipeline configuration preferably.
For achieving the above object, the present invention proposes a kind of grouting blended cement slurries, comprise following component, each component by weight: 700 parts, water, bentonite clay 150 parts, No. 425 ordinary Portland cements 75 parts, French chalk 74 parts, polyacrylamide additive 0.5 part and carboxymethyl cellulose additive 0.5 part.
The invention allows for a kind of pipeline configuration, comprise PE core pipe, outer tube sleeve and cement slurry packed layer, described PE core pipe is plugged in outer tube sleeve, adopts above-mentioned grouting blended cement slurries to be filled between described PE core pipe and described outer tube sleeve and forms described cement slurry packed layer.
Further, described outer tube sleeve is cast iron pipe box.
Grouting blended cement slurries of the present invention and pipeline configuration, can meet PE installation of core pipe, operation and maintenance demand preferably.The pH value of blended cement slurries is about 8-9, the slurries presetting time is 4-5 hour, good fluidity, be convenient to install, the coagulant after solidification is crisp block structure, and hardness is moderate, good fixing effect, can peel off easily again, easy to use and maintenance, use is filled in the slip casting being used as packed layer when the very applicable PE of being applied in core pipe is plugged in outer tube sleeve.
Be described further below with reference to the technique effect of accompanying drawing to design of the present invention, concrete structure and generation, to understand object of the present invention, characteristic sum effect fully.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment two pipeline configuration.
Embodiment
Embodiment one:
The present embodiment proposes a kind of grouting blended cement slurries, comprise following component, each component by weight: 700 parts, water, bentonite clay 150 parts, No. 425 ordinary Portland cements 75 parts, French chalk 74 parts, polyacrylamide additive 0.5 part and carboxymethyl cellulose additive 0.5 part.
Exemplary, 700 kilograms, water, bentonite clay 150 kilograms, No. 425 ordinary Portland cements 75 kilograms, French chalk 74 kilograms, polyacrylamide additive 0.5 kilogram and carboxymethyl cellulose additive 0.5 kilogram can be adopted to carry out the blended cement slurries of proportioning mixed configuration one ton, this slurries presetting time is 4-5 hour, good fluidity, very easy to use, and these blended cement slurries condensation after coagulant hardness moderate, in crisp block structure, namely fixing needs are met, be convenient to again later stage stripping needs, be especially suitable as pipeline and fill.
Of course, in other specific embodiments, according to the blended cement slurries of the required weight of above-mentioned weight configuration, can also repeat no more herein.
Embodiment two:
Fig. 1 is the structural representation of embodiment two pipeline configuration.As shown in Figure 1, the present embodiment also proposed a kind of pipeline configuration, comprise PE core pipe 100, outer tube sleeve 200 and cement slurry packed layer 300, PE core pipe 100 is plugged in outer tube sleeve 200, adopts grouting blended cement slurries described in embodiment one to be filled between PE core pipe 100 and outer tube sleeve 200 and forms described cement slurry packed layer 300.Exemplary, outer tube sleeve 200 adopts cast iron pipe box.
Adopt grouting blended cement slurries and the pipeline configuration of the present embodiment, PE installation of core pipe, operation and maintenance demand can be met preferably.The pH value of blended cement slurries is about 8-9, the slurries presetting time is 4-5 hour, good fluidity, be convenient to install, the coagulant after solidification is crisp block structure, and hardness is moderate, good fixing effect, can peel off easily again, easy to use and maintenance, use is filled in the slip casting being used as packed layer when the very applicable PE of being applied in core pipe is plugged in outer tube sleeve.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technician in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment.
