Description

Technical Field

[0001] The invention relates to the technical field of road construction, and in particular to the technical field of construction for connecting new and old roadbeds in widening new and old roads. Background Art

[0002] With the growing national economy, the rapid growth in the number of private cars, buses and trucks has greatly increased the traffic volume on the highway. The traffic volume on many highways has reached saturation, and it is imperative to upgrade the original highways. The widening of the highway roadbed is the key to the reconstruction project, both in terms of design and construction. After years of opening to traffic, the settlement of the original roadbed (old roadbed) has been basically completed. If the junction of the new and old roadbeds is not treated, the uneven settlement of the new and old roadbeds will inevitably cause damage to the junction of the new and old roadbeds, seriously endangering the quality of the highway. For this reason, it is urgent to provide a device for controlling the uneven settlement of the junction of the new and old roadbeds to reduce the uneven settlement of the junction of the new and old roadbeds.

[0040] Example 1

[0041] The existing technology has the problem of being unable to timely and accurately control the uneven settlement of the junction between the new and old roadbeds. In order to solve the shortcomings of the existing technology, embodiment 1 provides a device 01 for controlling the uneven settlement of the junction between the new and old roadbeds, such as Figure 1-2 As shown, it includes a pumping device 1, a flow pressure valve 2, an old roadbed liquid storage box 3 and a new roadbed liquid storage box 4; the pumping device 1, the flow pressure valve 2, the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4 are connected in sequence.

[0042] use Figure 1 The schematic diagram of the planar structure of the device for controlling uneven settlement at the junction of the new and old roadbeds is shown in the figure. Figure 2 As shown:

[0043] 1. Device assembly:

[0044] The liquid extraction device 1 is installed on the old roadside 003 and can be used to extract liquid, wherein the liquid can come from the drainage ditch or evaporation pond of the old roadside 003, and can also come from a liquid storage container specially used to store liquid.

[0045] The flow pressure valve 2 can be automatically adjusted according to the pressure change to achieve a pressure balance state inside the device 01 for controlling uneven settlement at the junction of the new and old roadbeds. Specifically, when the water pressure is balanced (the internal liquid of the device 01 for controlling uneven settlement at the junction of the new and old roadbeds is in a static equilibrium state), the flow pressure valve 2 is automatically adjusted to a closed state; when the water pressure is unbalanced (the internal liquid of the device 01 for controlling uneven settlement at the junction of the new and old roadbeds is in a flowing state), the flow pressure valve 2 is automatically adjusted to an open state, thereby controlling the flow balance inside the device.

[0046] The new roadbed liquid storage box 4 is fixed on the soil of the new roadbed 002. Figure 2 The old road was excavated into three steps 004 before construction, and the old roadbed liquid storage box 3 was fixed on the soil at the third step of the old roadbed 001. Among them, the installation requires that the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4 are on the same horizontal line.

[0047] like Figure 10-13 As shown, the new roadbed liquid storage box 4 includes a box top through hole 40, a support plate 41, a floating ball 42, a floating rod 43 and a spring support 44; the support plate 41 is arranged horizontally; the floating rod 43 is arranged in the vertical direction, the top end of the floating rod 43 is fixed to the support plate 41, and the bottom end of the floating rod 43 is fixed to the floating ball 42; the rod body of the floating rod 43 can float up and down in the box top through hole 40; the spring support 44 is fixed to the bottom of the new roadbed liquid storage box 4. Among them, the fixing method of the floating ball 42 and the floating rod 43 includes but is not limited to welding consolidation, and the fixing method of the floating rod 43 and the support plate 41 includes but is not limited to welding consolidation. The height of the floating rod 43 can be designed to be the allowable lifting value of the highway engineering design + 5mm.

[0048] like Figure 2 As shown, when the assembly is completed (liquid has not been injected yet), the support plate 41 is subjected to a downward force of its own weight, a downward pulling force applied by the floating rod 43, and an upward supporting force applied by the top of the new roadbed liquid storage box 4. Under the action of the above three forces, the support plate 41 is in a force balance state, and the support plate 41 remains stationary.

[0049] 2. Inject liquid:

[0050] After the assembly is completed, the flow pressure valve 2 is opened manually, and the pumping device 1 extracts liquid (for example, water in the drainage ditch at the edge of the old road 003), and the liquid flows through the pumping device 1 and the flow pressure valve 2 in sequence, and is finally injected into the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4. At this time, the liquid levels in the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4 rise.

[0051] When the liquid level in the new roadbed liquid storage box 4 rises to a height that interacts with the float 42, the entire structure composed of the float 42, the float rod 43 and the support plate 41 is subject to an upward buoyancy provided by the liquid, a downward gravity of the entire structure, and an upward support force exerted by the top of the new roadbed liquid storage box 4. Under the action of the above three forces, the entire structure is in a force balance state, at which time, the entire structure composed of the float 42, the float rod 43 and the support plate 41 (including the support plate 41) remains stationary.

[0052] As the liquid level rises, the volume of the floating ball 43 drainage increases, the buoyancy increases, and the support force applied by the top of the new roadbed liquid storage box 4 decreases accordingly. When the support force applied by the top of the new roadbed liquid storage box 4 is reduced to zero, that is, the top of the new roadbed liquid storage box 4 no longer applies support force to the support plate 41. The overall structure (including the support plate 41) composed of the floating ball 42, the floating rod 43 and the support plate 41 will have a movement trend with the rise of the liquid level (the support plate 41 is in a critical rising state). At this time, the flow pressure valve 2 is manually closed. With the closing of the flow pressure valve 2, the internal liquid of the device 01 for controlling the uneven settlement at the junction of the new and old roadbeds enters a static equilibrium state, and the pressure difference of the liquid between the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4 is zero. At this time, the water pressure in the new roadbed liquid storage box 4 can be measured through the box top through hole 40 of the new roadbed liquid storage box 4, and the critical water pressure of the flow pressure valve 2 is set. When the flow pressure valve 2 exceeds the critical water pressure, it will automatically open, and when the flow pressure valve 2 is less than the critical water pressure, it will automatically close. The initial setup was completed, and part of the construction of a device 01 for controlling uneven settlement at the junction of the new and old roadbeds was completed.

[0053] According to the actual situation of on-site construction, several groups of devices 01 for controlling uneven settlement at the junction of the new and old roadbeds can be set up, and the above steps can be repeated until the construction of the overall device composed of several groups of devices 01 for controlling uneven settlement at the junction of the new and old roadbeds is completed.

[0054] Then, the road is constructed normally, and the construction and maintenance are completed, and the overall device composed of several groups of devices 01 for controlling the uneven settlement at the junction of the new and old roadbeds begins to operate.

[0055] 3. Device operation

[0056] After installation, the internal liquid of the device 01 for controlling uneven settlement at the junction of the new and old roadbeds enters a static equilibrium state, at which time the pressure difference of the liquid between the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4 is zero.

[0057] If there is no uneven settlement at the junction of the new and old roadbeds, the internal liquid of the device 01 for controlling uneven settlement at the junction of the new and old roadbeds enters a static equilibrium state, there is no pressure difference between the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4, and the flow pressure valve 2 remains closed.

[0058] When the new roadbed 002 settles, and the settlement speed of the old roadbed 001 and the new roadbed 002 is greatly different, the new roadbed liquid storage box 4 sinks along with the settlement of the new roadbed 002, and a height difference is formed between the new roadbed liquid storage box 4 and the old roadbed liquid storage box 3, and the liquid in the old roadbed liquid storage box 3 automatically flows into the new roadbed liquid storage box 4. At this time, the flow pressure valve 2 detects that the critical water pressure is exceeded and opens automatically, and the pumping device 1 replenishes liquid for the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4 to provide liquid pressure. As the new roadbed liquid storage box 4 sinks, the liquid storage volume in the new roadbed liquid storage box 4 increases, the liquid level rises, and the overall structure composed of the float 42, the float rod 43 and the support plate 41 (including the support plate 41) has an upward movement trend as the liquid level rises. At this time, the support plate 41 is above the settlement soil layer, and the settlement soil layer will apply a downward pressure to the support plate 41, an upward buoyancy provided by the liquid on the overall structure composed of the float 42, the float rod 43 and the support plate 41, a downward overall structural gravity and a downward pressure applied by the settlement soil layer; when the above three forces establish a new force balance relationship, the overall structure composed of the float 42, the float rod 43 and the support plate 41 (including the support plate 41) will no longer continue to rise, and the internal liquid of the device 01 for controlling uneven settlement at the junction of the new and old roadbeds will enter a static equilibrium state again, and the flow pressure valve 2 will be closed. The supporting force provided by the support plate 41 to the settlement soil layer is equal to the pressure applied to the support plate 41 by the settlement soil layer.

[0059] That is to say, after uneven settlement occurs at the junction of the new and old roadbeds, the liquid storage box 4 of the new roadbed sinks, the liquid storage volume of the new roadbed liquid storage box 4 increases, and the liquid level rises, causing the float 42 to drive the float rod 43 and the support plate 41 to move upward. The support plate 41 provides support force for the settled soil layer, thereby reducing the settlement on the new roadbed 002 side.

[0060] Compared with the prior art, the present invention has the following beneficial effects:

[0061] (1) The device for controlling uneven settlement at the junction of the new and old roadbeds provided by the present invention can effectively reduce the uneven settlement at the junction of the new and old roadbeds, alleviate the development of cracks at the junction of the new and old roads during highway reconstruction and expansion, and improve the overall stability and durability of the highway reconstruction and expansion.

[0062] (2) The device uses water pressure to generate liquid buoyancy to offset the uneven settlement of the soil. The device controls the uneven settlement at the junction of the new and old roadbeds. The device operates efficiently, has a timely adjustment response speed, and has high sensitivity and accuracy.

[0063] (3) The materials used in the present invention are easy to obtain and low in cost. The overall installation of the device is simple and the construction process is simple. The damage to the old roadbed is small, thus saving capital investment in infrastructure projects.

[0064] (4) The device for controlling uneven settlement at the junction of new and old roadbeds provided by the present invention can be applied to the junction of new and old roadbeds and combined with traditional construction technology for reducing uneven settlement, thereby better reducing the uneven settlement at the junction of new and old roadbeds, better preventing the occurrence of cracks at the junction of new and old highway pavements, and improving the overall stability and durability of the pavement.

[0065] Specifically, Figure 3-4 As shown, the liquid pumping device 1 includes a liquid pump 10 and an electric energy supply device 11; the electric energy supply device 11 supplies electric energy to the liquid pump 10. The electric energy supply device 11 includes but is not limited to any one of a solar power supply device, a wind power supply device, and a wind-solar combined power supply device.

[0066] Since the pumping device is installed on the edge of the old road, in order to save costs, the power supply device 11 further includes a solar power supply device. For the specific application scenario of the edge of the old road, the conventional power supply device needs to lay wires and connect to the power grid, which is a large amount of work. The solar power supply device can adapt well to the surrounding environment of the road, is easy to install, and has low later operation and maintenance costs. In addition, the solar power supply device uses solar energy, a renewable energy source, to supply power. It is a green, safe, and environmentally friendly power supply device that conforms to the low-carbon and environmentally friendly construction concept.

[0067] Furthermore, if Figure 4 As shown, the power supply device 11 includes a solar cell assembly 110 and a socket 111; the solar cell assembly 110 and the socket 111 are electrically connected; Figure 3 As shown, the liquid pump 10 includes a liquid pump body 100, a liquid pump inlet pipe 101, a liquid pump outlet pipe 102, a liquid pump motor and a liquid pump power line 104; the liquid pump inlet pipe 101 and the liquid pump outlet pipe 102 are respectively connected to the liquid pump body 100; the liquid pump motor is used to drive the liquid to be transported inside the liquid pump body 100 along the direction from the liquid pump inlet pipe 101 to the liquid pump outlet pipe 102; Figure 1-2 As shown, the liquid pump motor is electrically connected to the socket 111 through the liquid pump power line 104. The liquid pump 10 includes but is not limited to a common water pump available on the market, and the model and flow rate of the liquid pump 10 can be adjusted according to the actual construction situation. The solar cell assembly 110 is arranged according to the actual construction site, and only the power of the solar cell assembly 110 is limited, and the power provided by the solar cell assembly 110 can meet the use requirements of the liquid pump 10.

[0068] In order to connect the old roadbed liquid storage box with the new roadbed liquid storage box, further, as Figure 1-2 As shown, the device 01 for controlling uneven settlement at the junction of the new and old roadbeds further includes a third connecting pipe 50 ; the third connecting pipe 50 connects the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4 .

[0069] In order to enable the new roadbed liquid storage box to move up and down relative to the old roadbed liquid storage box and ensure that the connection between the two is well sealed, further, Fig. 9 As shown, the third connecting pipe 50 includes a soft connecting pipe 500 and a first spring 501; the first spring 501 is sleeved on the outer side of the tube body of the soft connecting pipe 500. The tube body of the soft connecting pipe 500 has a certain flexibility and can be bent to a certain extent. At the same time, the two ends of the soft connecting pipe 500 can be connected to the liquid outlet 32 ​​of the old roadbed liquid storage box (see Figure 6 and Figure 7 ), new roadbed liquid storage box inlet pipe 45 (see Fig.10 and Fig.12 ) and ensure good sealing of the connection. On the other hand, because the body of the soft connecting pipe 500 has a certain flexibility and can bend, when the surrounding of the soft connecting pipe 500 is filled with soil layers, if the liquid pressure in the soft connecting pipe 500 is not enough to offset the squeezing force of the soil layer on the body of the soft connecting pipe 500, the soft connecting pipe 500 will be flattened, so that the effective flow cross-section of the soft connecting pipe 500 is greatly reduced, thereby adversely affecting the liquid transportation efficiency between the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4. In response to this problem, by sleeve-arranging a first spring 501 on the body of the soft connecting pipe 500, the first spring 501 has good circumferential compressive strength, which can protect the soft connecting pipe 500 inside from being squeezed by the soil layer, avoid pipeline blockage, and thus ensure that the liquid transportation efficiency between the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4 is stable for a long time.

[0070] Specifically, the length of the third connecting pipe 50 can be designed to be 50 mm, the thickness of the third connecting pipe 50 is 10 mm, and the soft connecting pipe 500 can be made of a corrosion-resistant and freely bendable material.

[0071] In order to achieve reliable fixation between the old roadbed liquid storage box and the soil at the third step of the old roadbed, further, as Figure 6 and Figure 8 As shown, the old roadbed liquid storage box 3 includes a fixed support 30; the force bearing point of the fixed support 30 is welded to the bottom of the old roadbed liquid storage box 3. Through the fixed support 30, the old roadbed liquid storage box 3 can be reliably fixed to the soil at the third step of the old roadbed 001.

[0072] Specifically, Figure 2 , 6 As shown in Figure 8, the fixed support 30 includes a plurality of first rivet insertion holes 300 and a plurality of first rivets 301; the fixed support 30 can be fixed in the soil through the cooperation of the first rivet insertion holes 300 and the first rivets 301. The plurality of first rivets 301 are nailed into the soil of the old roadbed 001 in the vertical direction, and the plurality of first rivets 301 form a plurality of support points, so that the fixed support 30 and the soil of the old roadbed 001 are firmly fixed.

[0073] Specifically, the number of the first rivets 301 can be designed to be 2, the diameter of the first rivet insertion hole 300 and the diameter of the first rivet 301 are both 60 mm; and the first rivet insertion hole 300 and the first rivet 301 are both made of steel material.

[0074] Furthermore, if Figure 2 , 10 As shown in 13, the spring support 44 includes a prestressed spring 440, a plurality of second rivet holes 441 and a plurality of second rivets 442; the prestressed spring 440 is arranged in the vertical direction; the top of the prestressed spring 440 is fixed to the bottom center of the new roadbed liquid storage box 4, and the bottom of the prestressed spring 440 can fix the spring support 44 in the soil through the cooperation of the second rivet holes 441 and the second rivet 442. Among them, the force point of the prestressed spring 440 is fixed at the bottom center of the new roadbed liquid storage box 4, and the second rivet holes 441 are symmetrically fixed on both sides of the bottom end of the prestressed spring 440.

[0075] Through the spring support 44, the new roadbed liquid storage box 4 can be reliably fixed to the soil at the base of the new roadbed 002. A plurality of second rivets 442 are nailed into the soil of the base of the new roadbed 002 in the vertical direction. At this time, a plurality of second rivets 442 form a plurality of support points, so that the spring support 44 and the soil of the base of the new roadbed 002 are firmly fixed. The spring support 44 enables the new roadbed liquid storage box 4 to move up and down within a certain range relative to the soil of the new roadbed 002 to which it is fixed. At the same time, since the prestressed spring 440 is elastic, when the soil layer on the side of the new roadbed 002 settles, the new roadbed liquid storage box 4 is driven to sink, and the length of the prestressed spring 440 is compressed and shortened. The prestressed spring 440 can provide a greater supporting force to the soil layer above it, which is conducive to delaying the settlement speed of the new roadbed side. The sinking of the new roadbed liquid storage box 4 also forms a height difference between the new roadbed liquid storage box 4 and the old roadbed liquid storage box 3 , and the liquid in the old roadbed liquid storage box 3 automatically flows into the new roadbed liquid storage box 4 .

[0076] Specifically, the prestressed spring 440 may have the following specifications: the diameter of the prestressed spring 440 is 100 mm, the original length of the prestressed spring 440 is 20 mm, and the maximum stretching amount of the prestressed spring 440 is 10 mm.

[0077] To achieve the connection between the pumping device and the flow pressure valve, further, as Figure 1-2 As shown, the device 01 for controlling uneven settlement at the junction of the new and old roadbeds also includes a first connecting pipe 51; Figure 5 As shown, the flow pressure valve 2 includes a flow pressure valve liquid inlet 20; the first connecting pipe 51 connects the pumping device 1 with the flow pressure valve liquid inlet 20. The first connecting pipe 51 connects the pumping device 1 with the flow pressure valve 2.

[0078] In order to provide a corrosion-resistant first connecting pipe, further, the first connecting pipe 51 is a PVC pipe. The PVC pipe is light, cheap, has good tensile and compressive strength, good water tightness, small fluid resistance, and excellent corrosion resistance and chemical resistance. Therefore, the PVC pipe does not require any anti-corrosion treatment when it is laid, and is therefore very suitable for connecting the pumping device 1 and the flow pressure valve 2.

[0079] Specifically, the PVC pipe can use the following specifications: 300 mm in length, 80 mm in diameter, and 10 mm in thickness.

[0080] To achieve the communication between the flow pressure valve and the old roadbed liquid storage box, further, as Figure 1-2 As shown, the device 01 for controlling uneven settlement at the junction of the new and old roadbeds also includes a second connecting pipe 52; the flow pressure valve 2 includes a flow pressure valve outlet 21 (see Figure 5); the second connecting pipe 52 connects the flow pressure valve outlet 21 with the old roadbed liquid storage box inlet pipe 31 (see Figure 6 and Figure 7 ) connected.

[0081] In order to provide a corrosion-resistant second connecting pipe, further, the second connecting pipe 52 is a PVC hose. The flow pressure valve liquid outlet 21 is connected to the liquid inlet of the PVC hose by pyrolysis. The PVC hose is light, cheap, has good tensile and compressive strength, good water tightness, small fluid resistance, and excellent corrosion resistance and chemical resistance. Therefore, the PVC hose pipeline does not require any anti-corrosion treatment when it is laid, and is therefore very suitable for connecting the flow pressure valve 2 and the old roadbed liquid storage box 3.

[0082] Specifically, the PVC hose can be used in the following specifications: 3000 mm in length, 70 mm in diameter, and 10 mm in thickness. Taking the midpoint of the PVC hose as the boundary, on one side of the boundary, the pumping device 1, the first connecting pipe 51, the flow pressure valve 2, and a part of the PVC hose 52 are arranged beside the ground road; on the other side of the boundary, another part of the PVC hose 52, the old roadbed liquid storage box 3, the third connecting pipe 50, and the new roadbed liquid storage box 4 are arranged on the roadbed.

[0083] The flow pressure valve 2 and the pumping device 1 are installed on the edge of the old road 003, and the old roadbed liquid storage box 3 is fixed on the soil at the third step of the old roadbed 001. There is usually a certain height difference between the flow pressure valve 2 and the old roadbed liquid storage box 3, and they are not located on the same horizontal plane. The use of a longer PVC hose can meet its basic strength requirements. Compared with the second connecting pipe formed by connecting multiple pipes, it simplifies the pipeline structure, saves the assembly time of the second connecting pipe, and reduces the risk of liquid leakage at the pipeline connection.

[0084] In order to protect the inherent shapes of the old roadbed liquid storage box and the new roadbed liquid storage box from being squeezed and deformed by the soil layer, the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4 are further made of hard materials. The old roadbed liquid storage box 3 and the new roadbed liquid storage box 4 made of hard materials have good mechanical strength and are not easily deformed by external forces. When the overall height of the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4 remains unchanged, it is beneficial to maintain the constant water pressure inside them.

[0085] In order to prevent the old roadbed liquid storage box and the new roadbed liquid storage box from corrosion, further, the inner and outer surfaces of the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4 are provided with anti-rust coatings. The anti-rust coatings can protect the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4 from corrosion by liquid or soil, reduce leakage or blockage of the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4 caused by corrosion, and thus help to extend the service life of the old roadbed liquid storage box 3 and the new roadbed liquid storage box 4.

[0086] The old roadbed liquid storage box 3 and the new roadbed liquid storage box 4 can be cut and welded by steel plates with an anti-rust coating on the surface. The old roadbed liquid storage box 3 must ensure that there is an old roadbed liquid storage box liquid inlet and an old roadbed liquid storage box liquid outlet at the bottom of the side of the old roadbed liquid storage box, and other parts remain sealed. The old roadbed liquid storage box liquid inlet and the old roadbed liquid storage box liquid outlet are used to insert the old roadbed liquid storage box liquid inlet pipe 31 and the old roadbed liquid storage box liquid outlet pipe 32 respectively. The new roadbed liquid storage box 4 must ensure that there is a new roadbed liquid storage box liquid inlet, and the new roadbed liquid storage box liquid inlet is used to insert the new roadbed liquid storage box liquid inlet pipe 45. A top through hole 40 is opened at the top of the new roadbed liquid storage box 4, and a float ball 42 is welded with a float rod 43. The float ball 42 is inside the new roadbed liquid storage box 4, and the float rod 43 passes through the top through hole 40 and is welded with a support plate 41 to keep other parts of the new roadbed liquid storage box 4 in a sealed state.

[0087] Specifically, the old roadbed liquid storage box 3 can be designed to have the following specifications: length, width and height are 400 mm respectively, and thickness is 25 mm. The old roadbed liquid storage box liquid inlet pipe 31 and the old roadbed liquid storage box liquid outlet pipe 32 are symmetrically distributed at the bottom of the side of the liquid storage box, the length of the old roadbed liquid storage box liquid inlet pipe 31 and the old roadbed liquid storage box liquid outlet pipe 32 are both 100 mm, and the diameter of the old roadbed liquid storage box liquid outlet pipe 32 is the same as the diameter of the old roadbed liquid storage box liquid inlet pipe 31. The old roadbed liquid storage box 3 is connected to the new roadbed liquid storage box 4. The old roadbed liquid storage box 3 mainly serves to transport liquid to the new roadbed liquid storage box 4 to balance the liquid pressure in the device.

[0088] The new roadbed liquid storage box 4 has the same size and material as the old roadbed liquid storage box 3. A new roadbed liquid storage box liquid inlet pipe 45 is arranged on one side of the new roadbed liquid storage box 4, and the length of the new roadbed liquid storage box liquid inlet pipe 45 is 100mm.

[0089] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
