Description
Technical field
The utility model relates to the technical field of the equipment hoisting of rural area small and medium-sized pumping station pump house, specifically a kind of packaged type composite material cover plate for pumping plant pump house overhaul of the equipments hole place of the middle-size and small-size row of filling, rural area and preparation method thereof.
Background technology
Pump house is the important structure in the drainage and irrigation project of rural area, plays a part to form a connecting link in irrigation and drainage process.In pump house, motor both sides are furnished with cover plate, are bearing in access hole edge, and its Main Function overhauls for convenience of staff, need to open cover plate during maintenance, do not need to utilize cover plate to be closed in aperture during maintenance.
The pump house cover plate of current use is mainly divided into wooden cover plate, reinforced concrete cover plate and steel deck-plate according to making material.But there is the problems such as perishable, movement difficulty, defening effect are poor toward contact in the cover plate of these traditional materials, for above-mentioned shortcoming, propose research and be mainly used in pump house equipment hoisting field, and meet lightweight, anticorrosion, be convenient to the general performance requirements such as mobile, can the task of general sheet material of large-scale promotion application.
One, wooden cover plate:
Wooden cover plate is made up of common wood, and compared with other building materials, timber is easy to processing, has lightweight, cheap advantage.During as structural element, timber tension and to be cut be all brittle fracture, its intensity is very large by the impact of the natural defects such as knaur, twill and crack.Timber is in air themperature, area that humidity is higher, and termite, moth, house longhorn beetle etc. are quite large to timber harm; When being in dampness, especially in drying and watering cycle frequently pump house, will be rotten by domestomycetes corrodes, there is certain safety problem.When being used as the structural element of main carrying, the often reduction due to the defect of material of its strength character, materials'use rate is not high, and waste is serious.
Two, reinforced concrete cover plate:
Reinforced concrete cover plate is made primarily of reinforcing bar and concrete, reinforcing bar bears pulling force, concrete bearing compressive force, closely knit concrete has higher intensity, simultaneously because reinforcing bar is wrapped up by concrete, not easily corrosion, maintenance cost is also little, so the durability of reinforced concrete structure is relatively good, there is firm, durable, that fireproof performance is good and anti-seismic performance is good advantage.But its shortcoming is, concrete tensile strength is low, and any perceptible tensile stress all can destroy concrete microcosmic rigid body lattice, causes concrete cracking and is separated, just easily crack after reinforced concrete cover plate reaches certain service time, and construction is by seasonal effect.Maximum shortcoming is that its deadweight is comparatively large, and the carrying in small-sized pump house and when being unfavorable for maintenance, makes troubles to service work, affect operating efficiency.
Three, steel deck-plate:
Steel deck-plate generally adopts Q235B hot rolling decorative pattern roll bending, and steel strength is higher, and modulus of elasticity is also high, compare with timber with concrete, the ratio of its density and yield strength is relatively low, and thus under same stress condition, the member section of steel work is little, from heavy and light, be convenient to transport and install.In addition, riffled iron can also play skidproof effect, and durable in use, handsome in appearance.But steel work corrosion-resistant, particularly in the pump house of moist and Korrosionsmedium, easy corrosion.Thereby increase the expense of later period maintenance.Meanwhile, because the sound insulation value of steel deck-plate is poor, steel plate can be driven to vibrate during pump running, the noise of generation is larger.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of pump house manhole composite material cover plate and preparation method thereof.
The technical solution adopted in the utility model is: a kind of pump house manhole composite material cover plate, comprises core, composite material face, skid resistant course and metal draw ring; Cloth is laid on upper and lower, forward and backward four surfaces of described core, and form composite material face Primary layer with resin solidification, the left and right side lapped layup cloth of core, and forming composite material face bonding layer with resin solidification, the upper surface of described composite material face is provided with skid resistant course and metal draw ring;
Described core material is Balsa wood, paulownia wood, China fir, oak or veneer;
The cloth of described composite material face adopts carbon fiber, glass fiber, basalt fibre, aramid fiber or hybridization fiber;
The resin of described composite material face adopts epoxy resin, vinylite, unsaturated polyester (UP) or phenolic resins.
The utility model is the anti-skidding composite material cover plate that mobility is stronger.Compared to conventional cover plate, thickness and weight greatly reduce, and performance obtains and significantly promotes simultaneously.In force, cover plate is supported on manhole place, when needing maintenance, by draw ring, cover plate one end is started, be easy to open.
A preparation method for above-mentioned pump house manhole composite material cover plate, comprises the following steps:
A. core is cut into given size;
B. core surfaces sawdust is removed;
C. cloth is laid on upper and lower, forward and backward four surfaces of core;
D. cloth bound edge is carried out to core edge;
E. lay release cloth, flow-guiding cloth successively outside cloth, mozzle, admission pipe are laid in outside, reexamine sealing condition;
F. vacuum pump air-breathing, checks sealing condition, installs resin ingress pipe, admission pipe, reexamines sealing condition;
G. open vacuum pump and resin ingress pipe, suck resin, after resin complete wetting, close vacuum pump and resin ingress pipe, wait for resin solidification quietly;
H. the demoulding carry out mold cleaning;
I. cloth is laid on core arranged on left and right sides surface, controls at 100mm with upper and lower surface cloth lap length, repeats d-h step and completes resin importing;
J. get out cylindrical draw-in groove at the upper surface of composite material face, be bolted iron draw ring base, metal draw ring is installed;
K. composite material cover plate is formed at the upper surface gold coated emery of composite material face and the nonskid coating of mixed with resin.
Beneficial effect: the utility model core all surface is laid by composite material and formed, take full advantage of the good fatigue durability of composite material and corrosion resistance, efficiently solve bearing capacity and the ductility of load-carrying members, improve its stress performance, this drying and watering cycle of pump house environment frequently can be adapted to.And the sound-proofing of core is good, from the advantage of heavy and light, be conducive to transport, handling and in-site installation, can suitability for industrialized production, overcome original common cover from shortcomings such as great, poor durability.And composite material upper surface scribbles skid resistant course and is fixed with metal draw ring, can anti-skidding again can operate time more simple and convenient.This type structure is ensureing that sandwich slab is on the basis possessing the good characteristics such as lightweight, high-strength, corrosion-resistant slide-resistant, significantly reduces its manufacturing cost, to realize the batch application of engineering field.
