Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline structures, and in particular relates to an auxiliary reinforcement device for a soft soil foundation drainage network. Background Art

[0002] Soft soil foundation refers to a weak soil layer with low supporting strength and high compression. It generally contains a large amount of organic matter and often appears in coastal areas, lakes, valleys, and river beaches.

[0003] When constructing roads and bridges on soft soil, the soft soil must first be reinforced. Otherwise, the soft soil will not provide sufficient support strength, and the road and bridge structures will easily collapse. The above reinforcement methods mainly include: replacement filling, dense pile method, vibroflotation method, and grouting method.

[0004] However, all of the aforementioned reinforcement methods for laying drainage pipe networks in soft soil are costly and difficult to implement. Generally, to prevent significant settlement of the drainage network, reinforcement devices are used to provide auxiliary support. After all, the weight of the drainage network is far less than that of the aforementioned road and bridge structures.

[0005] The common existing reinforcement device mentioned above mainly comprises a frame and a ring. The former is mainly used to increase the downward pressure area, and the latter is mainly used to connect the drainage pipe.

[0006] For example, the Chinese utility model patent with authorization announcement number CN218540761U and authorization announcement date 2023.02.28 discloses an assembled foundation auxiliary support device for road soft soil foundation drainage pipes, including a support mechanism, steel sheet piles, a first gravel layer, and side piles. The steel sheet piles are arranged on both sides of the support mechanism, the side piles are installed on the support mechanism, and the side piles pass through the first gravel layer. The drainage pipe is located on the support mechanism and in the first gravel layer. At the same time, the side piles are located on both sides of the drainage pipe.

[0007] The auxiliary support device in this utility model patent mainly functions to solve the problems of bulge or water gushing at the bottom of the foundation pit and instability of the foundation pit slope.

[0008] However, in actual use, the auxiliary support device still has at least the following shortcomings, which are also the technical problems to be solved by the present utility model, namely:

[0009] The only part of the device that can significantly increase the downward pressure area is its supporting mechanism, so the effect of increasing the area and reducing the pressure is not obvious enough. The entire device is prone to sinking when supporting the weight of the pipe. Therefore, even if the above-mentioned water gushing and slope instability problems are solved, it is difficult for the device to reinforce the drainage pipe in a long-term and stable manner.

[0010] Therefore, in summary, there is an urgent need for a new device with a larger downward pressure area in the frame structure to be used for auxiliary support of the drainage pipe network to prevent the rapid settlement of the pipeline in the soft soil foundation. Summary of the Invention

[0011] The utility model provides an auxiliary reinforcement device for a drainage pipe network in a soft soil foundation. By setting a horizontal protruding frame unit, a support bottom frame unit, and a tensile frame unit on the pipe collar, the following effects can be achieved: the device has a large support area, and on the premise that the weight of the drainage pipe remains unchanged, the pressure can be significantly reduced, preventing the device and the drainage pipe from significantly settling in the soft soil foundation, thereby achieving the reinforcement effect on the drainage pipe.

[0012] The technical solution adopted by the utility model to solve the above problems is: an auxiliary reinforcement device for a drainage pipe network in a soft soil foundation, the structure includes a pipe collar, and also includes a horizontal protruding frame unit arranged on the outer ring surface of the pipe collar, a support bottom frame unit arranged on the lower end surface of the horizontal protruding frame unit, and a tensile frame unit arranged on the upper end surface of the horizontal protruding frame unit and used for connecting the ground casting plate.

[0013] A further preferred technical solution lies in that: the horizontal protruding frame unit includes a horizontal protruding plate arranged on the outer ring surface of the pipe collar, a vertical plate arranged on the end surface of the horizontal protruding plate, and a middle support plate arranged at a position on the vertical plate away from the pipe collar.

[0014] A further preferred technical solution lies in that: the support bottom frame unit includes a lower connecting plate arranged on the outer ring surface of the pipe collar, and a bottom plate arranged on the lower connecting plate and connecting the vertical plate.

[0015] A further preferred technical solution lies in that: the tensile frame unit includes an upper connecting plate arranged on the outer ring surface of the pipe collar, a top plate arranged on the upper end surface of the upper connecting plate and connecting the vertical plate, and a tensile rod arranged on the top plate and used for connecting the ground casting plate.

[0016] A further preferred technical solution lies in that: the horizontal protruding frame unit further includes a vertical rod arranged on the middle support plate and connecting the bottom plate.

[0017] A further preferred technical solution lies in that: the support bottom frame unit further includes an additional plate arranged at a position below the bottom plate, and a support rod with both ends respectively arranged on the bottom plate and the additional plate.

[0018] A further preferred technical solution lies in that: the horizontally protruding frame unit further includes an inclined plate disposed on the side of the middle support plate and used to abut against the bottom plate.

[0019] A further preferred technical solution lies in that: the tension-resistant rod is inserted into the top plate; the tension-resistant frame unit further includes two adjusting nuts disposed on the tension-resistant rod and located on both sides of the top plate respectively.

[0020] A further preferred technical solution lies in that: the vertical rod is inserted into both the middle support plate and the bottom plate; the horizontally protruding frame unit further includes a plurality of pairs of connecting nuts disposed on the vertical rod and used to clamp the middle support plate and the bottom plate respectively.

[0021] A further preferred technical solution lies in that: the number of the horizontally protruding frame units is two, which are respectively located on both sides of the pipe collar. Description of the Drawings

Detailed implementation manner

[0034] The following is only the preferred embodiment of the present utility model, and does not limit the scope of the present utility model.

[0035] As shown in the appendix Figures 1-7 As shown, an auxiliary reinforcement device for a drainage pipe network in soft soil foundation, the structure includes a pipe collar 11, and further includes a horizontal protruding frame unit 1 provided on the outer ring surface of the pipe collar 11, a support bottom frame unit 2 provided on the lower end surface of the horizontal protruding frame unit 1, and a tensile frame unit 3 provided on the upper end surface of the horizontal protruding frame unit 1 and used for connecting the ground casting plate a.

[0036] In this embodiment, the pipe collar 11, the horizontal protruding frame unit 1, the support bottom frame unit 2 and the tensile frame unit 3 are all made of steel, and the surface is provided with an anti-rust layer.

[0037] Among them, the pipe collar 11 is sleeved with the drainage pipe b, which is a prerequisite for the device to assist in supporting the pipe and assisting in strengthening the entire drainage pipe network. By arranging several such devices at intervals on the drainage pipe network, its anti-settlement can be achieved, which is the meaning of the above-mentioned "auxiliary reinforcement". This is very necessary and practical for the drainage pipe network in soft soil foundation.

[0038] In addition, when the device is in use, the horizontal protruding frame unit 1, the support bottom frame unit 2 and the tensile frame unit 3 are all located in the soft soil foundation, that is, in the above-mentioned backfill soil d, and all have a large horizontal area, so the pressure generated by the self-weight of the drainage pipe b can be reduced, making it difficult to settle.

[0039] On the other hand, the pipe collar 11, the horizontal protruding frame unit 1 and the tensile frame unit 3 are welded into a whole, and the support bottom frame unit 2 can be either vertically abutted, screwed or also welded to the above-mentioned whole, as long as it is ensured that the weight on the drainage pipe b can be transmitted to the tensile frame unit 3.

[0040] Finally, when the device is installed, it can also be used in cooperation with the ground casting plate a, so that the ground casting plate a also shares the weight of the drainage pipe b, avoiding large settlement of the drainage pipe b. Among them, the above-mentioned ground casting plate a is generally a cast-in-place reinforced concrete plate.

[0041] The horizontal protruding frame unit 1 includes a horizontal protruding plate 101 provided on the outer circumferential surface of the pipe collar 11, a vertical plate 102 provided on the end surface of the horizontal protruding plate 101, and a middle support plate 103 provided on the vertical plate 102 at a position away from the pipe collar 11.

[0042] In this embodiment, the number of the middle support plates 103 is 2 - 3, which are horizontally arranged, and its lower surface is the effective part for sharing the weight and reducing the pressure. Therefore, the middle support plate 103 itself and the entire horizontal protruding frame unit 1 need to have sufficient rigidity to prevent the outer side edge of the middle support plate 103 from easily tilting upward and deforming.

[0043] The support bottom frame unit 2 includes a lower connecting plate 201 provided on the outer circumferential surface of the pipe collar 11, and a bottom plate 202 provided on the lower connecting plate 201 and connecting the vertical plate 102.

[0044] In this embodiment, between the lower connecting plate 201 and the pipe collar 11, and between the bottom plate 202 and the vertical plate 102, welding is optional. The lower connecting plate 201 and the middle support plate 103 are both rectangular in shape, and the length and width dimensions of the former are larger than those of the latter, thereby providing a sufficient support area.

[0045] The tensile frame unit 3 includes an upper connecting plate 301 provided on the outer circumferential surface of the pipe collar 11, a top plate 302 provided on the upper end surface of the upper connecting plate 301 and connecting the vertical plate 102, and a tensile rod 303 provided on the top plate 302 and used for connecting the ground casting plate a.

[0046] In this embodiment, welding is performed between the upper connecting plate 301 and the pipe collar 11, and between the top plate 302 and the vertical plate 102. The function of the tensile rod 303 is to finally share the weight of the drainage pipe b to the ground casting plate a, thereby further alleviating the settlement problem of the drainage pipe b.

[0047] When the auxiliary reinforcement device is produced and transported, it does not include the ground casting plate a, which needs to be cast in situ at the use site. Among them, the number of the tensile rods 303 is 2, which are located on both sides of the pipe collar 11, and they can be respectively cast on two ground casting plates a, or cast on a whole larger ground casting plate a.

[0048] The horizontal protruding frame unit 1 further includes a vertical rod 104 provided on the middle support plate 103 and connecting the bottom plate 202.

[0049] In this embodiment, both the middle support plate 103 and the bottom plate 202 are provided with openings for inserting the vertical rod 104. The function of the vertical rod 104 is to connect the middle support plate 103 and the bottom plate 202 into a force-bearing whole, so that the weight sharing effect of the device is better.

[0050] It does not matter whether the opening is a screw hole or the vertical rod 104 is a screw rod, as long as the vertical rod 104 can transmit the force vertically. For example, if the opening is an ordinary circular hole, the vertical rod 104 can be connected to it and then welded.

[0051] The supporting frame unit 2 further includes an additional plate 203 provided below the bottom plate 202 , and a supporting rod 204 with two ends respectively provided on the bottom plate 202 and the additional plate 203 .

[0052] In this embodiment, the additional plate 203 can be regarded as another piece of the base plate 202, which is used together with the support rod 204 to make the frame structure of the supporting base frame unit 2 stronger and able to withstand greater downward pressure.

[0053] The upper and lower ends of the support rod 204 are welded.

[0054] The laterally protruding frame unit 1 further includes an inclined plate 105 disposed on a side of the middle support plate 103 and used to abut against the bottom plate 202 .

[0055] In this embodiment, one of the sides of the middle support plate 103 is set on the vertical plate 102, and the inclined plates 105 can be set on the other three sides. This is so that the upward tilt of the two ends of the support base unit 2 when subjected to force can be distributed to the middle support plate 103, thereby avoiding excessive bending of the support base unit 2.

[0056] The lower side of the inclined plate 105 is not welded to the bottom plate 202 , but is merely pressed against each other, so as to provide a necessary foundation for the supporting chassis unit 2 to be independently detachable.

[0057] The anti-tension rod 303 is plugged into the top plate 302 ; the anti-tension frame unit 3 further includes two adjusting nuts 304 arranged on the anti-tension rod 303 and located at two sides of the top plate 302 .

[0058] In this embodiment, the relative height of the top plate 302 on the tension rod 303 is the approximate installation depth of the auxiliary reinforcement device. The function of the adjusting nut 304 is to make the above relative height adjustable and to ensure that it is fully fixed after adjustment.

[0059] The vertical rod 104 is inserted into both the middle support plate 103 and the bottom plate 202; the transverse protruding frame unit 1 further includes a plurality of pairs of connecting nuts 106 arranged on the vertical rod 104 and respectively used for clamping the middle support plate 103 and the bottom plate 202.

[0060] In this embodiment, screw holes for installing the vertical rod 104 are provided on the middle support plate 103 and the bottom plate 202, or the above openings do not have threads but are used in cooperation with the connecting nuts 106. Both of these methods can connect the transverse protruding frame unit 1 and the support bottom frame unit 2 into a force-bearing whole, so as to share the reaction force of the soft soil foundation on the two.

[0061] At the same time, this also makes the support bottom frame unit 2 detachable separately. Correspondingly, when there are 2 middle support plates 103, 6 connecting nuts 106 need to be provided on a single vertical rod 104. For details, please refer to the appendix Figure 3 .

[0062] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various modifications can be made without departing from the purpose of the present invention. These are all non-creative modifications and are protected by the patent law as long as they are within the scope of the claims of the present invention.
