Description
Technical field
The present invention relates to a kind of duct pieces of shield tunnel architecture prototyping test unit, particularly relate to a kind of push mode shield tunneling structure prototype experiment test water pressure applying device.
Background technology
To the applying of shield tunnel prototype segment structure hydraulic pressure, usually adopt and realize from the device of anchor hoop tuype, it is overlooked partial structurtes schematic diagram and sees Fig. 3.Its formation is: shield tunnel construction prototype 2 be placed vertically in ground (its central axis is perpendicular to the ground), outer peripheral face longitudinally arranges two hoop beams 3, hoop beam 3 side is provided with lifting jack 4, the top of hoop anchor cable 5 is through the top anchor cable hole on hoop beam 3, after rounding in shield tunnel construction prototype 2, its end is connected with the push rod of lifting jack 4 through the end anchor cable hole on hoop beam 3 again.Wherein, hoop beam 3 provides pressure to simulate and control structure water pressure by hoop anchor cable 5.But there is problem and the hidden danger of following two aspects in the charger of this self-anchored type hoop tuype:
First, due to lifting jack tonnage and size larger, when hoop beam both sides hoop anchor cable enters hoop beam from the section of jurisdiction outside surface of arc, because anchor cable hole is straight, its left and right sides is identical with the distance of shield tunnel construction prototypic surface, in addition, lifting jack tonnage and size larger, its top will cause the stretch-draw angle (α) inevitably producing about 14 ° ~ 17 ° with the distance of side, and the symmetrical anchor cable other end installed also certainly leads to the stretch-draw angle (β) of 14 ° ~ 17 °.Make hoop beam left and right near zone there is larger stretch-draw space, and produce additional concentrated force at hoop Liang Chu, when institute's simulated water pressure is larger, the impact that hoop Liang Chu adds concentrated force is very remarkable, has a strong impact on test effect.
Secondly, hoop anchor cable forms flex point at the edge A of anchor cable hole, and during stretch-draw, stress concentrates on herein, hoop anchor cable will be caused easily to rupture herein, there is potential safety hazard.
Summary of the invention
Object of the present invention is just to provide a kind of push mode shield tunneling structure prototype experiment test water pressure applying device, this device adopts push mode hoop loading method, to eliminate in self-anchored type hoop method hoop Liang Chu because the existence of additional concentrated force is to the interference of structure hydraulic analogue, and the potential safety hazard existed during hoop beam hoop anchorage cable stretching.Test findings is true and accurate more; Thus simulate the role and influence of environment hydraulic pressure to prototype tunnel structure more realistically, to provide more accurately the design of underwater shield tunneling structure and construction, test basis reliably, to ensure construction and the operation safety in tunnel; And the reliability of device is high, security is good.
The technical solution adopted for the present invention to solve the technical problems is: a kind of push mode shield tunneling structure prototype experiment test water pressure applying device, its composition is: axis parallel is provided with the plural lifting jack of circumference in the top of the tunnel structure prototype on ground, the two ends of lifting jack are respectively equipped with longitudinal left and right thrust beam body; Hoop anchor yoke intersects at the tunnel structure prototype top surface between left and right thrust beam body around tunnel structure prototypic surface after one week, the two ends after intersection are connected with left and right thrust beam body respectively.
Compared with prior art, the invention has the beneficial effects as follows:
Vertical tunnel structure prototype is changed into horizontal, even if the axis parallel of tunnel structure prototype is in ground, then on its surface around laying hoop anchor cable, hoop anchor cable to intersect at after the top surface of tunnel structure prototype stretch-draw anchor on the thrust beam of left and right again, lifting jack outside (both sides) applied thrusts in the middle of two thrust beams.Because hoop anchor cable forms a complete circle at tunnel structure prototypic surface, its stretch-draw angle is 0, there is not any stretch-draw space therebetween, therefore, any additional concentrated force can not be produced, completely eliminate hoop beam and add the adverse effect of concentrated force to constitution water pressure simulation; Make the simulation of constitution water pressure more true and reliable.Thus make test simulate the role and influence of environment hydraulic pressure to tunnel structure prototype more truly, to provide more scientific reliable test basis, to ensure construction and the operation safety in tunnel to the design of underwater shield tunneling structure and construction.
The side that above-mentioned left and right thrust beam body is relative installs pushing tow force transfer body respectively, arranges lifting jack between pushing tow force transfer body.
Lifting jack promotes force transfer body, by force transfer body, the jacking force of lifting jack is delivered to two beam bodies, avoids the stress raisers of lifting jack and beam body contact position.
Above-mentioned left and right thrust beam body has anchor cable hole, and hoop anchor cable is anchored on the lateral surface of left and right thrust beam body through after anchor cable hole; Anchor cable hole tilts, and its angle tilted makes not form flex point through the hoop anchor cable of left and right thrust beam body at peritreme place.
Like this, can make further hoop anchor cable thrust beam through and connecting place do not form flex point, do not produce stress in any position of thrust beam and concentrate, make hoop anchor cable firm, not easy fracture, come off, use safety.
Below in conjunction with accompanying drawing and concrete embodiment, the present invention is further described.
