Abstract
The invention relates to a multi-layer spheroid well cover, staying on the well frame which is set on the well casing, comprising cover lay, shell and core. The edge of well cover is flat and centre portion of it is spheroid. The shell, which is high-strength concrete covered by steel, comprises external steel plate, inner steel plate and foxtails connecting external and inner steel plate. High-strength concrete is constructed between inner and external steel plate. The core is built with high-strength foamed aluminium. Low attacking ability for anti-explosion load and anti-impact wave is solved. It can resist directly hitting by kinetic energy bomb.
Description
Technical field
The present invention relates to a kind of well lid, particularly a kind of anti-bullet, antiknock well lid.
Background technology
In order to prevent that kinetic energy weapon and explosion wave from entering the civil air defense ground engineering, improve the survival ability of underground construction, satisfy the visual plant service requirement of underground construction, need well lid to be set at the underground construction oral area.
The direct hit ability of existing well lid antiknock ripple, anti-kinetic energy weapon is low.According to the interrelated data report eighties, the well lid that the U.S. reinforces research in the seventies adopts dull and stereotyped ladle and compressible concrete port plug to form, and the simulated pressure of its static loading test is up to 600MPa.But from above-mentioned document as can be seen: existing well lid also exists following deficiency and needs further improved content:
1, existing well lid explosion-proof load and tough striking capabilities are not high, and the development along with raising of nuclear weapon accuracy at target and miniaturization can't solve the well lid structural strength problem under the high-strength impact loading on the well lid that acts on.
2, along with the conventional weapon accuracy at target improves rapidly, existing well lid can't be resisted kinetic energy weapon and directly hit.
3, existing well lid uses material too much, and weight is too big, the stressed property and the less stable of well lid.
Summary of the invention
The objective of the invention is to propose a kind of novel multi-layer housing oblate spheroid well lid, solve existing well lid explosion-proof load and the not high problem of shock resistance ripple striking capabilities; And the existing well lid of solution can't be resisted the problem that kinetic energy weapon directly hits; Also solve existing well lid and use material too much, weight is too big, the stressed property of well lid and the problem of less stable.
Technical scheme of the present invention: a kind of Ablate spherical well cover with multi-layer casting, this well lid is supported on the crib, and crib is seated on the pit shaft, it is characterized in that:
Whole well lid is made up of overlay, housing and inner core, and well lid limit portion is smooth, the middle part upwards protuberance to be oblate spheroid crown;
The housing of this well lid is the ladle High Strength Concrete Structures, and its ladle shell is made up of outer layer plate, inner layer steel plate and the pin that is connected inside and outside layer steel plate, has built high-strength concrete between inside and outside layer of steel plate;
The inner core of this well lid has been built high-strength foamed aluminium.
The overlay of above-mentioned well lid is high strength glass fibre reinforced fibrage and bulletproof ceramic sheet.
Flexible cushion pad between above-mentioned well lid and the crib.
Above-mentioned crib is the ladle High Strength Concrete Structures.
Beneficial effect of the present invention: the well lid of multilayer shell of the present invention is shaped as the oblate spheroid structure, and oblate spheroid well lid stress performance is good, not only saves material, and stress performance is good, helps ricochet.Well lid is the ladle concrete structure, beat in the ladle shell and built High Strength Concrete Structures, the high-strength foamed aluminium of compacting in the ladle shell can absorb the blast wave energy, decay conventional weapon penetration is to the interior certain depth of ladle shell and the generation shock wave that explodes, the strike that helps resisting shock wave; The outer steel linear plate of well lid ladle shell surface adopts outside high temperature negative pressure technique to be bonded with high-strength glass fibre composite material and bulletproof ceramic sheet, integral rigidity is good, the high-strength glass fibre composite layer combines with the bulletproof ceramic sheet, the bulletproof ceramic sheet is cracked when making the conventional weapon penetration, thereby having reduced stress concentrates, make kinetic energy weapon behind high velocity impact, play inclined to one side bullet effect, even ricochet, blast back energy reduces rapidly, conventional weapon directly hit to become indirectly hit, high-strength foamed aluminium layer in the ladle shell can decay the conventional weapon penetration to the interior certain depth of ladle shell and the generation shock wave that explodes, the ladle shell plays the effect of fine anti-conventional weapon fragment and the associating of shock resistance ripple, the penetration that stops the blast fragment has improved well lid explosion-proof shock wave load-carrying ability and the opposing conventional weapon directly hits the blast ability.Thereby solved the anti-kinetic energy weapon of thin walled shell and directly hit the problem of exploding; High-strength cushion rubber layer material is arranged between well lid and crib contact surface, play cushioning effect, help crib is passed in wave attenuation, help the stability raising that the anti-nuclear blast wave of well lid hits, reduced the contact stiffness on well lid and the crib binding face, can resistant function to the well lid the nuclear blast positive pressure of shock wave improve nearly 10 times, and adjusted design in proper range as requested can be resisted and be used advanced kinetic energy weapon to directly hit blast under the local war condition.
