Description

A kind of composite underground engineering main body panel and its manufacturing process
Technical field
The present invention relates to municipal underground engineering, and in particular to a kind of composite underground engineering main body panel and its manufacture work Skill.
Background technology
Underground engineering structure refers to the underground structure with certain function for being built in underground, such as basement, underground storage Pond, pipe gallery, cable duct etc..Wherein, such as pipe gallery refers to build a tunnel space in the underground in city, by discharge Several layings of the various municipal pipelines such as water, combustion gas, electric power, communication.Various pipeline centralized arrangements are facilitated pipeline to transport by this mode Row management and plant maintenance, can avoid due to embedded or maintenance pipeline and cause road surface repeat to excavate caused by trouble, and can To avoid corrosion failure of the soil to pipeline, also it is extended so as to the service life of pipeline.
Traditional underground engineering structure typically uses armored concrete box structure type, scene integral cast during construction. Because underground engineering is typically built in below the major trunk roads in city, using the construction method of live integral cast, construction speed is slow, Difficulty of construction is big, and body's structure quality is difficult to control.Also, underground engineering facility etc. is inside installation made of concrete During support etc., it is fixed on engineering structure inwall often through other fasteners, because of concrete own structural characteristics, is easily caved in Property destroy, especially support install it is more comprehensively descends job facilities, it is bigger by being influenceed.
The content of the invention
For above-mentioned problems of the prior art, the present invention proposes a kind of composite underground engineering main body panel (such as basement, pipe gallery, cistern, cable duct) and its manufacturing process, composite underground engineering master of the present invention Honorable plate, its is easy for installation, and self structure collapse resistant will not be destroyed.
Specifically, the present invention provides a kind of composite underground engineering main body panel, and it includes underground engineering main body panel And some fillers positioned at body interior, the underground engineering main body panel are to be integrally formed by SMC sheet shape moulding compound and interior Portion is provided with some reinforcing fibers and filler, several pieces main body panels connection composition underground engineering structure main body；The underground engineering Main body panel thickness is 6-20cm, 1.7~2g/cm of scope3。
Wherein, underground engineering main body panel thickness be 6-20cm not wait and it is adjustable, in addition, the underground engineering main body panel Various shapes, specification seriation.
Wherein, underground engineering main body panel is to put into the fibre-reinforced SMC sheet shape moulding compound with some fillers In mould, one-shot forming is molded under 120-175 DEG C, 3-7MPa.
In addition, the SMC sheet shape moulding compound include following weight parts it is each into：
Acrylic acid epoxy resin 50-60 parts, epoxidized polybutadiene resin 50-60 parts, bisphenol-A 30-40 parts, roving 70-80 parts, glass fiber treating compound 8-10 parts, the di-t-butyl hexane peroxide 10-15 parts of 2,5- dimethyl -2,5, peroxidating diisopropyl Benzene 5-8 parts, zinc stearate 3-5 parts, the double stearic amide 3-5 parts of vinyl, hydrated alumina 5-8 parts, molybdenum disulfide 1-2 parts.
In addition the present invention also provides a kind of manufacturing process of composite underground engineering main body panel as described above, and it is wrapped Include following step：
(1) SMC sheet shape moulding compound is covered to the diaphragm wrapped up in and removes to be placed in drawing and expects platform；(2) according to product weight and size SMC sheet shape moulding compound draw and cut out；(3) raw material pulled is placed in mould by certain distributing mode；(4) in 120- 175 DEG C, be molded one-shot forming in 3~5 minutes under 3-7MPa；(5) shaping is after standing 48-72 hours under normal temperature.
Wherein, composite underground engineering main body panel of the invention, can be used for various underground engineering facilities, not by ground Point, structure etc. limit, such as available for basement, pipe gallery, cable duct, cistern etc..
The underground engineering main body panel of the present invention is formed in one structure, for such as basement, pipe gallery, water storage During the underground engineering facility such as pond, cable duct, can arbitrarily set up the internals such as some supports inside it, internals directly by Firm part is fixed in panel body, will not be easily rupturable whole so as to destroy such as cement structures due to the less brittle fragility of SMC material Body fastness, the decorating position of internals is unrestricted, will not because stress point is single cause overall unbalance stress destroy and hold Beijing South Maxpower Technology Co. Ltd's power.In addition, the main body panel of the present invention is internally added with some fillers, the overall of main body panel is substantially increased Intensity.And the main body panel of the present invention, can be assembled, convenience in transport and installation.
