Abstract
The invention relates to an inspection well and a manufacturing method thereof, and in particular relates to an SMC (sheet moulding compound) mould pressing resin finished well and a manufacturing method thereof. The SMC mould pressing resin finished well comprises a well base, a well shaft and an adapting piece. The finished well adopts an SMC sheet material, high-temperature mould pressing resins and a mixture thereof, a glass filament cloth and the like, is manufactured by adopting a high-temperature high-pressure mould pressing forming method and has the characteristics of high strength, high toughness, acid and basic corrosion resistance, high and low temperature resistance, high sealing performance, commercialization and convenience in construction.
Description
Technical field
The present invention relates to a kind of manhole and manufacturing approach thereof, be specially SMC mold pressing resin finished product well and manufacturing approach thereof.
Background technology
Manhole is the vertical shaft of on the underground utilities position, building at a certain distance.The main pipeline that supplies service conduits, removing mud to reach in order to connect different directions, differing heights uses.Be commonly called as " inspection shaft ", be located at generally that draining blow-off line intersection, turning, caliber or the gradient change, locate at a certain distance on drop place and the straight line pipeline section, be convenient to make regular check on, the draining ancillary structure of cleaning and dredging pipeline.Traditional manhole has two kinds: the one, form with brick, and efficient was low, consuming time many when this manhole was built, easy to leak; The 2nd, the plastic product well, shortcoming is to be prone to wear out, intensity is low, and is fragile.
Summary of the invention
In order to solve the problems of the technologies described above, the present invention provides a kind of SMC mold pressing resin finished product well and manufacturing approach thereof.
SMC mold pressing resin finished product well comprises well seat, pit shaft and supporting, and this product is to adopt the SMC sheet stock, and hot press moulding resin and compound thereof, continuous glass fibre cloth form through high temperature, high pressure mold pressing.
The concrete technical scheme of the method for high temperature, high pressure compression molding comprises following step:
(1) continuous glass fibre is processed the cloth shape;
(2) the mold pressing resin compound is stirred, is sprayed on the continuous glass fibre cloth, treat that it is shaped after, required according to producing, be divided into the sheet material;
(3), the multilayer sheet stock is put into mould, through press, through high temperature, high pressure and compression moulding according to the actual production requirement;
(4) semiproduct with moulding are combined into the finished product inspection well;
(5) the engagement joint of table pack outside manhole is fastening with screw, scribbles the continuous glass fibre cloth of epoxy resin again with the surface, is wrapped in the engagement joint of the outer table pack of manhole, with antiseep.
Wherein, described resin mixture comprises SMC sheet stock, hot press moulding resin, styrene, PS mould material and heavy calcium carbonate.
The ratio of SMC sheet stock, hot press moulding resin, styrene, PS mould material, heavy calcium carbonate and continuous glass fibre is 14:14:14:7:100::20 in the described resin mixture.
Described multilayer sheet stock is minimum to be no less than 6 layers.
Described compression moulding is to be pressed into semiproduct, and semicircle watt tubular, entity toroidal are arranged, and circle, and be suppressed with at its edge can intermeshing interface.
Described compression moulding is to be pressed into the semiproduct that thickness is 1.2cm.
The temperature of described compression moulding pressing process is 120 ℃ to 140 ℃, and pressure is 600 tons/square metre.
The combination of described semiproduct is that interface is meshed butt joint, and is fastening with screw, adds weather strip at interface again, after add epoxy sealing and cling.
Use the produced finished product well of this method, owing to adopt the SMC sheet stock, hot press moulding resin and compound thereof, continuous glass fibre cloth etc. make through the method for high temperature, high pressure compression molding, and melting new technology, new material, new technology is one.Therefore intensity is high, and toughness is strong, acid-alkali-corrosive-resisting, and high-low temperature resistant, sealing performance is high, and non-leakage, finished productization are easy for installation in actual use, are beneficial to later clear and coherent.
The specific embodiment

Above proportion of raw material is 14:14:14:7:100::20.
Procedure of processing:
1, processes sheet stock
Continuous glass fibre is processed the cloth shape; Other materials is stirred, is sprayed on the continuous glass fibre cloth, treat that it is shaped after, according to the production demand, be divided into sheet-shaped material.
2, compression moulding
According to the actual production requirement, the multilayer sheet stock is put into mould, through press, be pressed into semiproduct, and be suppressed with intermeshing interface at its edge through HTHP.
Pressing process is temperature required to be: 130 positive and negative 10 degrees centigrade; Pressure is 600 tons every square metre; The semiproduct thickness of press forming is 1.2CM.
3, splicing is shaped
Mesh butt joint according to staying interface, fastening with screw, add weather strip at interface again, after add epoxy sealing and cling.
4, outer wall is handled
Treated continuous glass fibre cloth (inside and outside respectively scribbles one deck epoxy resin) is fixed on the inspection shaft skin, and drying is solidified.
