Description

Adjusting device suitable for building differential settlement
Technical Field
The invention belongs to the field of buildings, and particularly relates to an adjusting device suitable for building differential settlement.
Background
At present, the damage of buildings caused by uneven settlement is quite common, and particularly in areas with poor soil quality in south China, the cracking phenomenon of the outer wall of the building caused by uneven settlement caused by insufficient rigidity of the upper part of the building or improper basic treatment is rare. In addition, the foundations of the cross-river and cross-sea bridges are mostly positioned on poor foundations, and foundation treatment is also a difficult problem.
At present, domestic buildings (including bridges) mostly adopt a structure with cooperative stress of an upper structure, a foundation and a foundation, so that the damage caused by uneven settlement is relieved by adopting methods such as indirect integral reinforcement of the upper structure, deep foundation use, foundation treatment and the like, but the relieving effect is poor, and the risk of economic loss caused by the damage still exists.
Disclosure of Invention
The invention aims to provide an adjusting device suitable for uneven settlement of a building, which aims to release additional force on an upper structure caused by uneven settlement as far as possible while ensuring that the upper structure, a foundation and a foundation are stressed together, and simultaneously protect the upper structure, the foundation or a support.
The purpose of the invention is realized by the following technical scheme:
the adjusting device comprises an inner barrel, an outer barrel, a moving column, a plurality of liquid outlet mechanisms and a plurality of liquid inlet mechanisms, wherein the outer barrel is sleeved outside the inner barrel, an inner cavity filled with a liquid is formed in the inner barrel, the moving column is vertically movably arranged in the inner cavity, an outer cavity filled with the liquid is formed between the inner barrel and the outer barrel, a plurality of inner barrel liquid outlet holes and inner barrel liquid inlet holes which are communicated with the inner cavity and the outer cavity are formed in the inner barrel along the circumferential direction, the liquid outlet mechanisms comprise liquid outlet rods which can horizontally move and are used for controlling the opening and closing of the liquid outlet holes of the inner barrel, and the liquid inlet mechanisms comprise liquid inlet rods which can horizontally move and are used for controlling the opening and closing of the liquid inlet. The bottom surface of the movable column is in contact with the liquid level of the first liquid in the inner cavity. In the invention, liquid outlet and liquid inlet are relative to the inner cylinder, an inner cavity surrounded by the inner cylinder bears the pressure brought by the moving column, and the outer cylinder stores the first liquid for liquid exchange and is directly communicated with the atmosphere in general.
The liquid outlet mechanisms comprise a main liquid outlet mechanism and at least one auxiliary liquid outlet mechanism which are communicated, the main liquid outlet mechanism and the auxiliary liquid outlet mechanism respectively comprise a first shell arranged on the outer side of the outer cylinder, a first accommodating cavity filled with No. two liquids is formed in the first shell (the No. two liquids in the first accommodating cavity are added through a first passage), the main liquid outlet mechanism further comprises a first knob penetrating through the first shell and a first partition plate movably arranged in the first accommodating cavity, the first knob is connected with the first partition plate, the first accommodating cavity is divided into a first liquid accommodating cavity with variable volume and a first cavity by the first partition plate, a plurality of outer cylinder limiting holes I communicated with the first accommodating cavity are horizontally arranged on the outer cylinder along the circumferential direction, and the liquid outlet rod comprises a liquid outlet thick rod part matched with the outer cylinder limiting holes I and a liquid outlet thin rod part matched with the inner cylinder liquid outlet holes, the liquid outlet thick rod part can be horizontally and movably arranged in a first accommodating cavity (the liquid outlet thick rod part in the main liquid outlet mechanism is positioned in the first liquid accommodating cavity), an outer barrel constraint hole I and an outer cavity in sequence, the liquid outlet thin rod part can be horizontally and movably arranged in the outer cavity, an inner barrel liquid outlet hole and the inner cavity in sequence, and the liquid outlet thin rod part is provided with a liquid outlet groove along the length direction. The liquid outlet rod is equivalent to a one-way valve, so that the inner cylinder only can discharge liquid and can not feed liquid, and the movement is realized through the pressure difference between the two ends of the liquid outlet rod (specifically, the difference between the force applied to the end part positioned in the first accommodating cavity and the force applied to the end part positioned in the inner cavity). Before the adjusting device works, the first separating plate is moved inwards or outwards through the first knob, the volume of the first liquid containing cavity is reduced or increased, so that the liquid level of the second liquid is increased or reduced, the pressure of the second liquid at a specific position (namely the position of the liquid outlet thick rod part) in the first containing cavity is increased or reduced, and the pressure is converted into a movement control threshold value of the liquid outlet rod on a stress surface of the liquid outlet thick rod part. The size of the first liquid accommodating cavity in the main liquid outlet mechanism is adjusted by changing the position of the first partition plate, so that a threshold value is set, namely the first accommodating cavities in the main liquid outlet mechanism and the auxiliary liquid outlet mechanism both provide constant liquid pressure, and the first partition plate in the main liquid outlet mechanism can achieve the purpose of setting the threshold value, so that the first partition plate does not need to be adjusted in the using process and only needs to be adjusted before being used.
Liquid outlet communicating pipes are arranged between the main liquid outlet mechanism and the auxiliary liquid outlet mechanism and between the auxiliary liquid outlet mechanism and the auxiliary liquid outlet mechanism, and the liquid level of the second liquid in the first accommodating cavity of each liquid outlet mechanism can be raised or lowered through the liquid outlet communicating pipes. According to the principle of a communicating vessel, the liquid level of the second liquid in the first containing cavity in the other auxiliary liquid outlet mechanisms is equal to the liquid level of the second liquid in the first containing cavity (specifically, the first liquid containing cavity) in the main liquid outlet mechanism in height, the second liquid in the first containing cavity is lifted in the first channel, and the liquid level of the second liquid in the first channel can be obviously lifted due to the small liquid volume of the first channel, so that the synchronous lifting of the hydraulic pressure in each first containing cavity is ensured.
The outer diameter of the thick liquid outlet rod part is larger than that of the thin liquid outlet rod part, so that the thick liquid outlet rod part cannot enter the liquid outlet hole of the inner cylinder, and therefore limiting is achieved.
And a liquid outlet rod sealing ring is arranged on one side of the liquid outlet thick rod part, which is positioned on the liquid outlet thin rod part. Under the condition that the pressures applied to the two ends of the liquid outlet rod are inconsistent, particularly the pressure applied to the thick liquid outlet rod part is greater than the pressure applied to the thin liquid outlet rod part, the liquid outlet rod moves inwards until the thick liquid outlet rod part is clamped on the liquid outlet of the inner cylinder, and the liquid outlet rod sealing ring is favorable for sealing effect. When the adjusting device is in a balanced state, the liquid outlet rod sealing ring is abutted against the outer side wall of the inner barrel body, one end of the liquid outlet thin rod part, which is far away from the outer barrel, is positioned in the inner cavity, and the liquid outlet groove is sealed, namely the liquid outlet hole of the inner barrel is closed.
The first casing is improved level and is run through and be equipped with the first auxiliary hole that is linked together with first chamber that holds, but be equipped with horizontal migration's scale indicator and first spring assembly in the first auxiliary hole, the one end and the scale indicator of first spring assembly link to each other, and the other end links to each other with the inside wall of first casing, and the internal diameter in first auxiliary hole is the step change, and the external diameter of scale indicator also is the step change. When no second liquid is injected into the first accommodating cavity (namely the scale indicating rod is not subjected to liquid pressure), the zero scale position of the scale indicating rod is just flush with the end part of the first auxiliary hole to display that the pressure is not set at the moment, when the scale indicating rod moves outwards, the scale indicating rod is subjected to the tensile force of the first spring set, and when the pressure intensity applied to the scale indicating rod is reduced, the scale indicating rod can be reset by the first spring set. The scale indicating rod can indicate the movement control threshold (pressure value) of the liquid rod, the scale on the scale indicating rod can be calibrated through tests and can also be calculated by using theoretical numerical values, and therefore the control of the threshold is more convenient and visual. The recommended theoretical calculation principle is as follows: for the liquid outlet rod which makes the movable column sink, the threshold value should be the cavity hydraulic pressure (the pressure representative value divided by the sectional area of the inner cavity) corresponding to the pressure representative value determined by dividing the limit value of the local pressure bearing of the upper structure plus the weight of the movable column or the limit value of the punching damage value plus the weight of the movable column (the pressure change generated by neglecting the change of the liquid level of the liquid in the cavity at the moment) by the proper safety factor. If the stressed areas on the two sides of the liquid outlet rod are consistent, the pressure of the inner cavity is the pressure of the first accommodating cavity when the pressure is balanced, but the stressed areas on the two sides of the liquid outlet rod in the device are not consistent, the recommended scale is the pressure value for pushing the liquid outlet rod by the inner cavity, and the calculation formula is (the end surface area S2 of the liquid outlet rod in the first accommodating cavity and the pressure in the first accommodating cavity)/the end surface area S1 of the inner cavity.
A plurality of feed liquor mechanisms are including the main feed liquor mechanism and at least one vice feed liquor mechanism that are linked together, main feed liquor mechanism and vice feed liquor mechanism are all including the second casing of locating the urceolus outside, the inside formation of second casing is filled has the second of No. two liquids to hold the chamber (the second holds No. two liquids in the chamber and is added by No. two passageways), main feed liquor mechanism is still including the second knob that runs through the second casing and movably locate the second division board that the chamber was held to the second, second knob and second division board are connected, the second division board holds the chamber with the second and divides into changeable second liquid and holds chamber and second cavity, be equipped with a plurality ofly along circumference level and hold the urceolus about aperture II that the chamber is linked together with the second, the feed liquor pole is including setting gradually and with the first feed liquor thin pole portion of urceolus about aperture II looks adaptation, second spring assembly and the second feed liquor thin pole portion of inner tube looks adaptation, the first liquid inlet thin rod part is arranged in a second containing cavity (the first liquid inlet thin rod part in the main liquid outlet mechanism is positioned in the second liquid containing cavity), an outer barrel constraint hole II and an outer cavity in a horizontal moving mode in sequence, a liquid inlet limiting ring is arranged on the first liquid inlet thin rod part along the circumferential direction, the second spring group is arranged in the outer cavity in a horizontal moving mode, the second liquid inlet thin rod part is arranged in the outer cavity, an inner barrel liquid inlet hole and an inner cavity in sequence in a horizontal moving mode, and a liquid inlet groove is formed in the second liquid inlet thin rod part along the length direction. The liquid inlet rod is equivalent to a one-way valve, so that the inner cavity only can be filled with liquid but not discharged with liquid.
Between main feed liquor mechanism and the vice feed liquor mechanism, be equipped with feed liquor communicating pipe between vice feed liquor mechanism and the vice feed liquor mechanism, according to the linker principle, the liquid level of the second liquid that the second in all the other vice feed liquor mechanisms held the chamber will be as high as the liquid level of the second liquid that the second held the chamber (specifically means the second liquid and holds the chamber) in the main feed liquor mechanism, the second holds the second liquid in the chamber and goes up and down in No. two passageways, because No. two passageways are very tiny, therefore the liquid level of No. two liquid in little liquid volume just can make No. two passageways is showing and is ascending, and guarantee that each second holds the hydraulic pressure of intracavity and rise in step.
The external diameter in the thick pole portion of feed liquor is greater than the external diameter in the thin pole portion of first feed liquor, the external diameter in the thin pole portion of first feed liquor is unanimous with the external diameter in the thin pole portion of second feed liquor, the both ends in the thin pole portion of second feed liquor are equipped with the arch for the external diameter at second feed liquor thin pole portion both ends is greater than the external diameter in the middle part in the thin pole portion of second feed liquor. When the regulating device is in a balanced state, the end part of the second liquid inlet thin rod part, which is far away from the outer cylinder, just abuts against the connecting part of the inner cavity and the liquid inlet hole of the inner cylinder, and the end part of the second liquid inlet thin rod part, which is close to the outer cylinder, is positioned in the outer cavity, so that the liquid inlet groove is blocked, namely the liquid inlet hole of the inner cylinder is closed. After second feed liquor thin rod portion moved inwards, because the existence of feed liquor spacing ring, the one end that second spring assembly and first feed liquor thin rod portion link to each other can't be along with the second feed liquor thin rod portion moves inwards, consequently second feed liquor thin rod portion can receive the pulling force from second spring assembly, and when the pressure that comes from in the exocoel that the second feed liquor thin rod portion received was less than the pressure that comes from in the inner chamber that receives, second spring assembly just can make second feed liquor thin rod portion reset.
The level runs through to be equipped with the second auxiliary hole that holds the chamber and be linked together with the second on the second casing, but the thick pole portion of feed liquor thin pole portion tip is still including locating to the feed liquor thick pole portion of first feed liquor thick pole portion, but the second auxiliary hole is located to the thick pole portion horizontal migration of feed liquor in, be equipped with the scale on the thick pole portion of feed liquor. The zero scale position on the liquid inlet thick rod part is exactly level with the end part of the second auxiliary hole to display that the pressure is not set at the moment, the liquid level of the second accommodating cavity (namely the cavity for controlling the liquid inlet threshold value) should not change theoretically during working (but can be adjusted before working), because the part of the liquid inlet rod soaked in the second liquid (comprising the first liquid inlet thin rod part and the liquid inlet thick rod part) is designed into a force transmission component, when the second liquid acts on the liquid inlet thick rod part and the first liquid inlet thin rod part in the outer cavity acts on the first liquid inlet thin rod part, the liquid inlet thick rod part and the first liquid inlet thin rod part can be pushed outwards (the 'outer' refers to the outside relative to the whole device). However, the first liquid feeding thin rod part is connected with the second spring group, so that the degree of outward movement is limited, namely, when the liquid feeding thick rod part moves outwards and drives the first liquid feeding thin rod part to move outwards, the spring in the second spring group is stretched (because the pressure in the inner cavity and the outer cavity is consistent, the second liquid feeding thin rod part can be limited by the bulge on the second liquid feeding thin rod part to move outwards, namely, the joint of the second spring group and the second liquid feeding thin rod part cannot move, and the joint of the second spring group and the first liquid feeding thin rod part can move outwards), a pulling force can be generated on the first liquid feeding thin rod part, and after the pulling force of the second spring group offsets the pressure (or the pushing force) of the second liquid on the liquid feeding thick rod part, the liquid feeding thick rod part can stop being pushed outwards. The function of liquid feeding can be realized only when the inner cavity generates negative pressure relative to the outer cavity, the second liquid feeding thin rod part is attracted towards the inner cavity and successfully overcomes the elastic force of the second spring group. The scale on the liquid inlet thick rod part can be calibrated through tests and can also be calculated by using theoretical numerical values, so that the control of the threshold value is more convenient and visual. The recommended theoretical calculation principle is as follows: for the liquid inlet rod capable of lifting the moving column, the threshold value should be set as the critical tension value when the superstructure is damaged by the upward concentrated tension (the pressure change generated by neglecting the liquid level change of the liquid in the cavity at this time) divided by the cavity liquid pressure corresponding to the tension representative value obtained after the safety factor (the tension representative value is divided by the cross-sectional area of the cavity). Because the movement of the first liquid inlet thin rod part and the liquid inlet thick rod part is under the combined action of the pressure generated by the first liquid in the inner cavity, the pressure generated by the first liquid in the outer cavity, the elastic force generated by the second spring group, the pressure generated by the second liquid in the second accommodating cavity, the external pressure and other factors, and because the moving column directly connected with the building directly acts on the first liquid in the inner cavity, the pressure of the first liquid in the inner cavity can best reflect the threshold meaning of the device, the device is easier to operate, the practical operation personnel is prevented from needing to carry out conversion work, the scale on the liquid inlet thick rod part corresponds to the pressure in the inner cavity, and secondary factors such as pressure change and the like caused by the liquid level change of the second liquid in the second accommodating cavity due to the movement of the liquid inlet thick rod part are ignored in the calculation process (the ignored reason is that if the device starts to feed liquid, make the thick pole portion of second spring assembly inwards pull-in liquid, the thick pole portion of feed liquor can extrude the second and hold No. two liquids in the intracavity like this for the liquid level of No. two liquids risees slightly, and No. two liquids will be little grow to the pressure of the thick pole portion of feed liquor like this, are favorable to the thick pole portion of feed liquor to reset, therefore can ignore).

The inner diameters of the first channel and the second channel are very small, if the liquid outlet rod moves outwards a little, the liquid level of the second liquid in the first channel can be obviously raised, so that the pressure of the second liquid on the liquid outlet thick rod part is increased, and the liquid outlet of the inner cylinder can be closed by moving inwards.

And a floating sealing ring is arranged on the liquid level of the first liquid in the outer cavity. The floating sealing ring floats on the liquid and can move up and down along with the liquid level of the liquid, the floating sealing ring has the function of preventing foreign substances such as dust and the like from immersing to pollute the liquid, and the floating sealing ring adopts the existing equipment. The top of the outer cylinder is not provided with a sealing cover, so that the first liquid can be directly added into the outer cavity for supplement.
The first liquid in the inner cavity and the first liquid in the outer cavity should be lighter liquids (such as mineral oil and light oil), because the pressure of the liquid at the one-way valve is not only related to the load transmitted by the building, but also related to the pressure generated by the self weight of the liquid, but the pressure in the building is usually MPa (10)6Pa) and the liquid pressure is typically kPa (10) without the free liquid level being too high3Pa) levelThe difference between the two is 100-1000 times, so that the liquid pressure generated by the liquid gravity can be ignored by selecting the lighter low-density oil liquid.
The liquid II in the first accommodating cavity and the liquid II in the second accommodating cavity should use liquid with higher density such as carbon tetrachloride to ensure the efficient operation of the control device. If the pressure in the oil cavity can not meet the requirement only by the self-weight pressure of the liquid, the oil pipe can be sealed by adding a bolt, and the bolt is used as a sealing element to be installed in a threaded hole for bearing pressure (the formula of the liquid pressure is p)0+ ρ gh, where p0The pressure on the free surface of the liquid, in the present invention, p0I.e. the atmospheric pressure in the first channel and the second channel, and rho gh is the hydraulic control part of the device. However, since the height of the apparatus is limited, when ρ gh reaches the limit and cannot satisfy the requirement, p needs to be increased by another member0When the first channel or the second channel is sealed by the bolt, the surface of the liquid can be extruded on the sealed bolt when the liquid rises, the free liquid level is lost, and the bolt can apply pressure to the second oil in the first channel or the second channel, so that the pressure p is enabled to be applied to the second oil in the first channel or the second channel0Can be provided by the bolt, reach higher liquid pressure), reach bigger liquid pressure, because No. two liquid in first holding chamber and the second holding chamber has lost free liquid level this moment, consequently can guarantee through the bolt pressure-bearing that the hydraulic pressure of first holding chamber and the interior specific position of second holding chamber reaches the regulation value.

The volume of the inner cavity is equal to that of the outer cavity, so that the situation that the first liquid in the inner cavity is completely pressed out of the outer cavity and the outer cavity cannot contain the first liquid or the first liquid in the outer cavity is completely pressed into the inner cavity and the inner cavity cannot contain the first liquid is avoided, and the phenomenon that the device overflows or empties in the using process is prevented. Because the top of the outer cylinder body is flush with the top of the inner cylinder body, and the outer diameter of the base of the inner cylinder is consistent with the inner diameter of the outer cylinder body, the height of the inner cavity is the same as that of the outer cavity, the thickness of the inner cylinder body is increased for arranging the liquid inlet hole of the inner cylinder and the liquid outlet hole of the inner cylinder by neglecting the bottom of the inner cylinder body, and the relation between the inner diameter R of the inner cylinder body and the inner diameter R of the outer cylinder body can be calculated to2＝R。
When the regulating device is not used, the volume of the liquid I in the inner cavity is equal to the volume of the liquid I in the outer cavity or the volume of the liquid I in the inner cavity is slightly smaller than the volume of the liquid I in the outer cavity, because the device hopes that when the volume of the inner cavity below the moving column is maximum, the liquid I in the outer cavity flows into the inner cavity completely or mostly, and when the inner cavity is compressed to the minimum, the liquid I in the outer cavity cannot overflow so much, so that according to the requirement, the volume of the liquid I in the outer cavity is slightly larger than the volume of the liquid I in the inner cavity, and the outer cavity is enough to contain the liquid I filled in by the inner cavity.
The first liquid in the inner cavity can be directly injected from the top of the inner cylinder (at the moment, the movable column limiting ring is not installed on the inner cylinder body, and the movable column is also not installed in the inner cavity), and the first liquid in the outer cavity can be directly injected from the top of the outer cylinder.
The working principle of the liquid inlet mechanism in the device is (the upper structure supported by the movable column transmits pressure to the movable column for explanation): the inner cavity, the outer cavity, the first containing cavity and the second containing cavity are filled with liquid, when the movable column is subjected to external force from the upper part and the external force is larger, the pressure is transmitted to the first liquid in the inner cavity, the liquid outlet rod is subjected to pressure to generate a trend of moving towards the first containing cavity where the second liquid is located, when the pressure transmitted by the first liquid in the inner cavity of the liquid outlet rod completely exceeds the pressure of the second liquid in the first containing cavity, the liquid outlet rod moves outwards, the liquid outlet groove in the liquid outlet thin rod part is partially located in the outer cavity at the moment, the inner cavity and the outer cavity are communicated, the first liquid in the inner cavity can flow into the outer cavity through the liquid outlet groove, the liquid level of the first liquid in the inner cavity is reduced, the pressure relief purpose is achieved, the movable column moves downwards at the moment, and the movable column is difficult to settle when the pressure of the movable column is usually reflected by the pressure of the movable column (namely, the movable column is difficult to settle and is formed like a common foundation to support a building which tries to settle downwards Building), at this moment, because the pressure release effect, the device has shortened, therefore the settlement of building relative to the basis has been alleviated, the pressure of corresponding inner chamber has just been alleviated, the pressure that goes out liquid thin rod portion and receives from the liquid in the inner chamber reduces, and the thick pole portion that goes out liquid that is located first holding chamber receives and comes from the pressure that goes out liquid thin rod portion if the pressure that goes out liquid in the first holding chamber No. two liquid (No. two liquid is pressed into the liquid level of No. two liquid and is risen because of going out liquid rod outward in the passageway) is greater than the pressure that goes out liquid thin rod portion, goes out liquid rod this moment and moves inwards again, closes inner tube liquid outlet hole, through making a round trip at least, alright realize this adjusting device's balanced state under this exogenic action, do not feed liquid nor go out between inner chamber and the outer chamber, the mobile column is static, releases the relative displacement that. When the device is under tension or the pressure transmitted to the movable column by the liquid in the inner cavity is greater than the pressure of a building, the working state of the adjusting device is opposite to the working principle, the movable column rises and circulates at least once in a reciprocating way, so that the adjusting device can be properly extended when the upper building needs to be extended. In other cases, the adjustment device is adjusted according to the principles described above. Wherein, the concrete number of times of reciprocating cycle is according to actual conditions, because this device majority is used for the natural settling state, that is to say, need longer time just can subside a bit distance, the acceleration and the speed of removal post so can be ignored, like this, only need once feed liquor or once play liquid just can reach the purpose, generally the business turn over liquid is repeatedly because having taken place rapid settlement such as earthquake effect many times, the speed of carriage release lever this moment is not negligible, therefore when subsiding in place, the carriage release lever still has considerable kinetic energy, have to rely on the business turn over of liquid, kinetic energy is consumed so that the carriage release lever is stable as early as possible to the shrink inflation of a liquid volume in the inner chamber.

1) the force of the settlement or tension of the foundation on the building can be alleviated, the force is transferred, the common stress of the upper structure, the foundation and the foundation is ensured, the additional force caused by uneven settlement on the upper structure is released as far as possible, and the redundant force such as additional bending moment and the like is released as far as possible, so that the upper structure, the foundation or the support is protected at the same time.
2) The liquid inlet mechanism and the liquid outlet mechanism with adjustable pressure threshold values are configured in the adjusting device, so that the adjusting device is suitable for different working conditions, the flexibility of design and installation is guaranteed, the liquid is controlled to enter and exit by utilizing the one-way valve structure so as to achieve the volume change of the device and further release the relative settlement of the upper structure and the foundation, the automatic adjustment can be realized only by adjusting the parameters of the one-way valve when the device is initially arranged, the external force is not needed, and the labor and the electricity are saved.
3) The liquid inlet and outlet are controlled by hydraulic pressure, the liquid inlet rod and the liquid outlet rod, so that the lifting of the movable rod is controlled, the movable rod is automatically adjusted, external operation or energy sources such as electric power and the like are not needed, energy is saved, the environment is protected, and meanwhile, due to the liquidity of the liquid, the whole device is stressed uniformly, and the force bearing of the device is facilitated.
