Abstract
The invention discloses a hydraulic base adjusting device capable of eliminating deviation of a shield from a design axis during shield in and out of a tunnel. A hydraulic mechanism is formed by the following arrangement: a pedestal of the device is connected with a moveable part; the upper end of the moveable part is connected with a vibration pad; a cylindrical protrusion at the lower end of the moveable part is positioned in a hydraulic cavity of the pedestal; a hydraulic channel at the lower end in the hydraulic cavity is connected with a hydraulic cylinder; and a hydraulic valve is arranged between the hydraulic channel and the hydraulic cylinder. The lower part of the pedestal is connected with the vibration pad; the adjusting device is arranged between the base and the concrete floor; and the shield is placed on the base. The device has the advantages of high accuracy of adjusting the base, lifting capability, capacity of reducing or lifting the height of the base conveniently to make the shield accord with the design axis and meet the design requirement, guarantee of the construction quality of the shield, high integral balance and coordination, simple structure, easy production and operation, and low cost.
Description
Technical field
The hydraulic regulating device of off-design axis when the present invention relates to a kind of solution and eliminating shield structure turnover hole.
Technical background
Adopt shield method to build tunnel or various underground pipeline, generally be installation, debugging and the test running of in building good active well in advance, carrying out the shield structure, and it is shelved on exactly meets on the pedestal that designs axis, after treating that all preparation of construction work are ready, beginning is along design axis tunneling construction in the stratum, when the shield structure will be reached home, should accurately measure the present situation position of shield structure, and adjust and control its attitude, the shield structure is correctly entered build in advance on the pedestal in the mounted received well.But very easily depart from original design route during shield structure turnover hole, for example, when shield structure turnover hole, shield structure pedestal deforms, and makes shield driving axis runout design axis, and this has had a strong impact on the normal turnover hole of shield structure.
The problem of off-design axis relies on shield structure turnover hole construction technology to realize mostly when solving shield structure turnover hole at present, comprise the method (mainly containing well-points dewatering method, high-pressure rotary jet grouting pile, deep-mixed pile, freezing process and SMW worker's method) that adopts rational soil mass consolidation, rational operation etc.Off-design axis problem when but these methods can not fundamentally solve shield structure turnover hole, and can only reduce this deviation to a certain extent.How when shield-tunneling construction, particularly adjust this deviation accurately during shield structure turnover hole is the problem that the researcher explored always.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned defective, and design provides a kind of hydraulic base adjusting device of diasporometer axis when eliminating shield structure turnover hole.
A kind of hydraulic base adjusting device of off-design axis when eliminating shield structure turnover hole, there is a columned hydraulic cavities 4 in base 3 central authorities that it is characterized in that this device, one side lower part in chamber has hydraulic channel 5, be connected on the hydraulic cylinder 7, between hydraulic cylinder 7 and hydraulic channel 5, be provided with hydraulic valve 6, above the movable part 2 is vibration isolator 1, lower central has a columniform projection, be placed in the columned hydraulic cavities 4, and mate mutually, base 3 bottoms connect vibration isolator 1, this adjusting device 8 is placed between pedestal 9 and the concrete floor 10, pedestal 9 places on the vibration isolator 1 on top, and the vibration isolator 1 and the concrete floor 10 of bottom join, and shield structure 11 places on the pedestal 9.
When being higher than the design axis when shield structure turnover hole, as long as open hydraulic valve 6, carry out step-down, the projection of movable part 2 lower ends is in being lowered into hydraulic cavities 4, and base height reduces, and the shield structure also descends thereupon, and it is consistent with the design axis that decline backing structure should keep; When being lower than the design axis when shield structure turnover hole, can boost by hydraulic mechanism rises movable part 2, and base height increases, and the shield structure also rises thereupon, and it is consistent with the design axis that rising backing structure should keep.

Reference numeral: hydraulic base adjusting device, 9-pedestal, 10-concrete floor, the 11-shield structure of off-design axis when 1-vibration isolator, 2-movable part, 3-base, 4-hydraulic cavities, 5-hydraulic channel, 6-hydraulic valve, 7-hydraulic cylinder, 8-eliminate shield structure turnover hole.
The specific embodiment
As shown in Figure 1: base 3 lower surfaces are connected with vibration isolator 1, and base 3 adopts cast iron materials, and specification is 800mm * 600mm * 1000mm; Vibration isolator 1 usefulness elastomeric material is made, and specification is 800mm * 600mm * 150mm, and top vibration isolator 1 is fixedlyed connected with movable part 2, and movable part 2 adopts steel; In the lower end of movable part 2 are projections, and cylindrical, its diameter is 300mm; Be a hydraulic cavities 4 in the middle of the high 750mm of cylinder, base 3, also cylindrical, be complementary with the cylindrical projection of movable part 2 lower ends, its chamber diameter is 305mm, the dark 800mm in chamber, this projection is in hydraulic cavities 4; A side has hydraulic channel 5 in the bottom of hydraulic cavities 4, is connected on the hydraulic cylinder 7, and a hydraulic valve 6 is set between hydraulic channel 5 and hydraulic cylinder 7; Above-mentioned movable part 2, hydraulic cavities 4, hydraulic channel 5, hydraulic valve 6 constitute hydraulic mechanism with hydraulic cylinder 7.
During application, as shown in Figure 1, 2: this adjusting device 8 is placed on the pedestal 9 and between the concrete floor 10, top vibration isolator 1 is connected with the contact of pedestal 9 lower surfaces, and following vibration isolator 1 is connected with concrete floor 10 contacts.When shield structure 11 passes in and out hole off-design axis (being mainly vertical direction), just need suitably reduction or raising base height to meet the design axis to guarantee the shield structure.When needs reduce base height,, carry out step-down as long as open hydraulic valve 6, the projection of movable part 2 lower ends is in being lowered into hydraulic cavities 4, and base height reduces, and the shield structure also descends thereupon, the height that descends is millimetre-sized, and it is consistent with the design axis that decline backing structure should keep; Otherwise also can boost by hydraulic mechanism rises movable part 2, and base height increases, and the shield structure also rises thereupon.
Owing to a plurality of adjusting devices 8 need be placed between pedestal 9 and concrete floor 10, so integrated system of each hydraulic mechanism, automatically adjusting is fallen or is risen, average out or coordinate, base height is evenly risen or decline, thereby the shield structure is also evenly risen or decline, reach consistent with the design axis.
