Description

Technical Field

[0001] This application relates to the field of road construction technology, and more specifically, to a support structure and building for widening construction of highway bridge abutments. Background Technology

[0002] When widening the highway abutment, it is necessary to first partially excavate the old abutment slope. The backfill material of some old abutment slopes is medium sand, which has extremely poor self-stability. After the slope soil is excavated, the medium sand flows out, causing slope instability and collapse, voiding of the old roadbed, and road subsidence. This can easily lead to traffic accidents for vehicles traveling at high speeds. Conventionally, concrete retaining walls are used for protection. However, in the widening construction at this location, due to the high fluidity of the medium sand layer, the medium sand in the old roadbed will flow out rapidly after the slope soil is excavated, causing the roadbed to void and triggering traffic accidents. During the construction of the retaining wall, the old roadbed may collapse, causing a production safety accident and rendering the road unusable.

[0003] There is currently no effective solution to the problem of construction difficulties caused by the instability of the old roadbed during the widening of structures such as bridge abutments in related technologies, which may lead to collapse or slippage. Summary of the Invention

[0004] The main objective of this application is to provide a support structure for the widening construction of highway bridge abutments, in order to solve the problem of construction difficulties caused by the instability of the old roadbed leading to collapse and slippage during the widening construction of bridge abutments and other structures.

The top end of the second support part is fixed in the second fixing hole on the second support plate of the first support leg, and the tail end of the second support part is fixed in the second fixing hole on the first support plate of the second support leg.

[0010] Furthermore, the two ends of the third support are respectively fixed in the second fixing holes of the first support plate of the first support leg and the second support plate of the first support leg, and fixed in the second fixing holes of the first support plate of the second support leg and the second support plate of the second support leg.

[0028] like Figure 1As shown, this application relates to a support structure for widening construction of highway bridge abutments. The support structure for widening construction of highway bridge abutments includes: a support shed 1, which includes a top plate 2 and a bottom plate 3, with a plurality of first support portions 4 disposed between the top plate 2 and the bottom plate 3; a first support leg 5 disposed at the top of the bottom side of the support shed 1; a second support leg 6 disposed at the tail end of the bottom side of the support shed 1; a plurality of second support portions 7 disposed between the first support leg 5 and the second support leg 6; each of the first support leg 5 and the second support leg 6 includes a first support plate 8, a second support plate 9, and a third support plate 10, with the third support plate 10 disposed between the first support plate 8 and the second support plate 9; a plurality of third support portions 11 disposed between the first support plate 8 and the second support plate 9; a first connecting plate 12 disposed between the support shed 1 and the first support leg 5; and a second connecting plate 13 disposed between the support shed 1 and the second support leg 6.

[0029] Specifically, during the widening of the old highway abutment bridge, the existing bridge abutment slope needs to be excavated before the new and old abutments are spliced. After partial excavation of the old abutment slope, it was discovered that some of the backfill material was medium sand, which has extremely poor self-stability. The flow of medium sand after the slope excavation caused slope instability and collapse, voiding of the old roadbed, and road surface subsidence, easily leading to traffic accidents for vehicles operating on the Changchun-Shenzhen Expressway. The support structure shed 1 used in this highway abutment widening construction directly supports the old roadbed. Support shed 1 includes a top plate 2 and a bottom plate 3. The double-layer support plate provides a double support effect. Several first support parts 4 are set between the top plate 2 and the bottom plate 3, increasing the stability of support shed 1. Different lengths of first support parts 4 can also be replaced as needed to adjust the height of support shed 1. Suitable for different scenarios, preferably, the top plate 2 and the bottom plate 3 are provided with a plurality of first fixing holes. The top end of the first support part 4 is fixed in the first fixing hole of the top plate 2, and the tail end of the first support part 4 is fixed in the first fixing hole of the bottom plate 3. When it is necessary to adjust the height of the support shed 1, the bottom ends of several first support parts 4 of different lengths are first placed into the first fixing holes on the bottom plate 3, and then the top ends are placed into the first fixing holes on the top plate 2. In this way, the height can be adjusted. Preferably, the first support parts 4 are arranged at equal intervals between the top plate 2 and the bottom plate 3. The equal interval arrangement helps to distribute the force on the top plate 2 and the bottom plate 3 and improve the service life. The first support leg 5 and the second support leg 6 are used for support. The supporting canopy 1 is symmetrically arranged at both ends of the supporting canopy 1, bearing the pressure of the core and playing the main role of supporting the supporting canopy 1. Optionally, the first supporting leg 5 and the second supporting leg 6 can be made of wood or steel. Using steel is easier to process and install, and has a greater load-bearing capacity and is more stable and reliable. At the same time, it can also provide greater strength and rigidity. Several second supporting parts 7 are arranged between the first supporting leg 5 and the second supporting leg 6. Preferably, the second supporting parts 7 are evenly spaced between the first supporting leg 5 and the second supporting leg 6, which helps to distribute the force on the first supporting leg 5 and the second supporting leg 6, improves stability and service life. Preferably, the first supporting plate 8 and the second supporting part 7 are arranged in a way that is conducive to distributing the force on the first supporting leg 5 and the second supporting leg 6. The second support plate 9 has several second fixing holes. The top end of the second support part 7 is fixed in the second fixing hole on the second support plate 9 of the first support leg 5, and the tail end of the second support part 7 is fixed in the second fixing hole on the first support plate 8 of the second support leg 6. The second support part 7 supports the first support leg 5 and the second support leg 6 to limit the distance between the two support legs and prevent inward displacement due to pressure on both sides of the first support leg 5 and the second support leg 6, thereby improving the stability of the support legs. The first support leg 5 and the second support leg 6 each include a first support plate 8, a second support plate 9, and a third support plate 10. The third support plate 10 is placed between the first support plate 8 and the second support plate 9 to serve as a connection and support.A plurality of third support portions 11 are provided between the first support plate 8 and the second support plate 9 to enhance the connection and stability. Preferably, both ends of the third support portions 11 are fixed in the second fixing holes of the first support plate 8 and the second support plate 9 of the first support leg 5, and in the second fixing holes of the first support plate 8 and the second support plate 9 of the second support leg 6, respectively. The third support portions 11 reinforce the first support leg 5 and the second support leg 6, preventing the support legs from shifting inward and improving stability. Preferably, the third support portions 11 are evenly spaced between the first support plate 8 and the second support plate 9, which helps to distribute the force on the first support plate 8 and the second support plate 9. Preferably, it also includes... Several fasteners are used to connect the support shed 1, the first support leg 5, the second support leg 6, the first connecting plate 12, and the second connecting plate 13. Optionally, if wood is used, the fasteners are self-tapping screws. Preferably, the fasteners first pass through the base plate 3, and then through the connecting plate to fix the support shed 1 to the top of the first support leg 5 and the second support leg 6. Alternatively, self-tapping screws can be used to pass through the base plate 3 and then through the connecting plate to fix the support shed 1 to the first support leg 5 and the second support leg 6. Optionally, if the first support leg 5 and the second support leg 6 are made of steel, the base plate 3 can be welded to the connecting plate, and then the connecting plate can be welded to the top of the first support leg 5 and the second support leg 6. In this way, the support shed 1 can achieve a stable support effect.

[0030] As can be seen from the above description, this application achieves the following technical effects:

[0031] In this embodiment, a multi-support structure is used to support the support shed 1 and prevent the support legs from shifting under pressure. The support shed 1 includes a top plate 2 and a bottom plate 3, with a plurality of first support parts 4 disposed between the top plate 2 and the bottom plate 3; a first support leg 5 is disposed at the top bottom side of the support shed 1, and a second support leg 6 is disposed at the bottom tail side of the support shed 1. A plurality of second support parts 7 are disposed between the first support leg 5 and the second support leg 6; both the first support leg 5 and the second support leg 6 include a first support plate 8, a second support plate 9, and a third support plate 10, with the third support plate 10 disposed between the first support leg 5 and the second support leg 6. Between the first support plate 8 and the second support plate 9, a plurality of third support parts 11 are provided; a first connecting plate 12 is provided between the support shed 1 and the first support leg 5; a second connecting plate 13 is provided between the support shed 1 and the second support leg 6, thereby achieving the purpose of using two support legs and three support parts to stably support the support shed 1, thus realizing the technical effect of stably supporting the old roadbed during widening construction, thereby avoiding the collapse of the old roadbed, and solving the technical problem of construction difficulties caused by the instability of the old roadbed during the widening construction of bridge abutments and other structures.

[0032] This invention also provides a building with a support structure for widening construction of highway abutments. It achieves the same technical effects as the support structure used in widening construction of highway abutments.
