[0002] The renovation of old urban pipe networks is an important part of the renovation of municipal pipelines, especially urban sewage pipe networks. Because they are buried deep and there are mostly built structures on both sides of the road, it is impossible to carry out slope excavation. Temporary support and protection measures are needed for the excavated pits to ensure the personal safety of construction workers. Larsen steel sheet piles are mostly used in the existing technology. Larsen steel sheet piles are made of high-quality steel, have high strength and durability, can withstand greater pressure and load, and have advantages in terms of materials and construction costs. However, the insertion and removal of Larsen steel sheet piles during the support process is relatively time-consuming. At the same time, cross braces need to be set for deeper pits, which takes a lot of time.

[0042] The embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0043] like Figure 1As shown, the utility model proposes a temporary protective device for municipal pipeline construction, including: a first baffle 10, a second baffle 20, a telescopic arm 30 and a reinforcing diagonal brace 40; wherein the first baffle 10 and the second baffle 20 are arranged opposite to each other, and adjacent first baffles 10 and adjacent second baffles 20 are respectively connected by tongues and grooves 13. It can be understood that a plurality of first baffles 10 and second baffles 20 are sequentially connected along the length direction of the groove; one end of the telescopic arm 30 is hinged to the first baffle 10, and the other end is detachably connected to the second baffle 20; the telescopic arm 30 can be extended and retracted to make the first baffle 10 and the second baffle 20 abut against the side wall of the foundation pit; the two ends of the reinforcing diagonal brace 40 are respectively connected to the first baffle 10 and the second baffle 20, and a plurality of reinforcing diagonal braces 40 are staggered.

[0044] In actual use, the side wall of the municipal pipeline trench formed by excavation is not a regular plane, so it is inevitable that the first baffle 10 and the second baffle 20 are not completely symmetrical when they are attached to the side wall of the trench. The present application sets a telescopic arm 30 hinged to the first baffle 10, so that one end of the telescopic arm 30 can rotate around the hinge part, and the angle and extension direction of the telescopic arm 30 can be adjusted according to the positional relationship between the first baffle 10 and the second baffle 20, so that it can connect the first baffle 10 and the second baffle 20; then, by adjusting the length of the telescopic arm 30, the first baffle 10 and the second baffle 20 can be against the side wall of the trench, effectively resisting the two sides of the trench The lateral pressure of the side soil body prevents the soil bodies on both sides from collapsing into the inside of the trench, thereby realizing the protection function of the trench; in addition, the reinforced diagonal brace 40 is also connected to the first baffle plate 10 and the second baffle plate 20, which can play a limiting function and effectively prevent the first baffle plate 10 from moving, so that the overall device has good anti-deformation performance; in addition, since the reinforced diagonal brace 40 is staggered, it forms a number of triangular frames together with the telescopic arm 30, the first baffle plate 10 and the second baffle plate 20, which can assist the telescopic arm 30 to form a support for the first baffle plate 10 and the second baffle plate 20, and jointly resist the lateral pressure of the soil body, further improve the stability of the overall device, and finally achieve a stable support for the side wall of the trench.

[0045] Preferably, if Figure 3 , Figure 4 As shown, the telescopic arm 30 includes a toothed rod 31 and a sleeve 32, and the sleeve 32 is sleeved on the toothed rod 31. In the present application, the cross-sectional shapes of the toothed rod 31 and the sleeve 32 are both square, and the sizes of the two are matched so that the toothed rod 31 can move along its length direction when inside the sleeve 32. The sum of the length of the sleeve 32 and the length of the toothed rod 31 extending out of the sleeve 32 is the length of the telescopic arm 30.

[0046] Furthermore, the telescopic arm 30 also includes an adjusting piece 33 for adjusting the movement of the toothed rod 31; specifically, the toothed rod 31 is provided with a toothed belt 311 along its length direction. In the present application, the toothed belt 311 is arranged on one of the side surfaces of the toothed rod 31, and at the same time, a first mounting portion is provided on the side surface of the sleeve 32 corresponding to the toothed belt 311, and the adjusting piece 33 is rotatably connected to the first mounting portion. The first mounting portion includes a correspondingly arranged opening and a first connecting seat 11. Specifically, the adjusting piece 33 is fixed to the first connecting seat 11 through a first pin shaft 332, and can extend into the sleeve 32 through the opening to engage with the toothed belt 311. When the adjusting piece 33 is rotated, the toothed rod 31 can be driven to move, thereby adjusting the length of the toothed rod 31 extending out of the sleeve 32; in the present application, the first mounting portion is provided at one end close to the connection portion between the sleeve 32 and the toothed rod 31.

[0047] Furthermore, if Figure 5 As shown, the adjusting member 33 includes a connecting portion 334 and a ratchet portion 331 and a handle 333 respectively arranged at both ends of the connecting portion 334. The connecting portion 334 is fixed to the first mounting portion through a first pin shaft 332. The ratchet portion 331 enters the interior of the sleeve 32 through the opening of the sleeve 32. Its cross-sectional shape is an arc, and the surface of the arc surface is distributed with ratchets meshing with the toothed belt 311; the handle 333 is located on the outside of the sleeve 32 and is designed to be a shape that is easy for a person to hold; by rotating the handle 333, the toothed rod 31 can be driven to move in the direction of extending out of the sleeve 32 or retracting into the sleeve 32.

[0048] Furthermore, when the adjusting member 33 adjusts the length of the telescopic arm 30 to meet the use requirements, it is necessary to limit the continued movement of the toothed rod 31, so the telescopic arm 30 in the present application also includes a limiter 34; Figure 3 , Figure 4 As shown, the sleeve 32 is provided with a second mounting portion, the second mounting portion includes an opening and a second connecting seat 11, and the stopper 34 is movably arranged on the second mounting portion, and can enter the sleeve 32 through the opening to engage with the toothed belt 311, so as to clamp the toothed belt 311. In the present application, the second mounting portion and the first mounting portion are arranged along the length direction of the sleeve 32, and the second mounting portion is close to the first mounting portion and is arranged on a side of the first mounting portion away from the connection portion between the sleeve 32 and the toothed rod 31.

[0049] Specifically, Figure 6As shown, the limiting member 34 is fixed to the second connecting seat 11 through a second pin shaft 341 , and the limiting member 34 and the second connecting seat 11 are provided with matching limiting holes 342 , and when the limiting member 34 is rotated to a set angle, the limiting holes 342 of the two are connected. The shape of one end of the limiting member 34 extending into the sleeve 32 is constructed to match the shape of the toothed belt 311, and can be stuck between the two teeth of the toothed belt 311; in this embodiment, the limiting member 34 when not in use is inclined to the side opposite to the moving direction of the toothed belt 311, and does not contact the toothed belt 311, so that the toothed rod 31 can move; when the limiting member 34 is needed to limit, the limiting member 34 is rotated to make it perpendicular to the toothed belt 311, at this time, one end of the limiting member 34 is engaged with the toothed belt 311, and at the same time, the limiting member 34 is connected with the limiting hole 342 of the second mounting portion, and the limiting member 34 can be fixed to the second connecting seat 11 by passing a bolt through the limiting hole 342, thereby realizing its limiting function on the toothed rod 31.

[0050] During operation, the first baffle 10 and the second baffle 20 are placed on the two side walls of the groove respectively. At this time, the adjusting member 33 and the limiting member 34 are not in contact with the toothed belt 311. The length of the telescopic arm 30 is preliminarily adjusted according to the width of the groove, and the other end of the telescopic arm 30 is connected to the second baffle 20. Then, the length of the telescopic arm 30 is adjusted again by rotating the adjusting member 33 until the first baffle 10 and the second baffle 20 both hit the soil on both sides of the groove. At this time, the limiting member 34 is controlled to clamp the toothed belt 311, thereby realizing the preliminary installation of the first baffle 10 and the second baffle 20.

[0051] Furthermore, if Figure 2 As shown, the first baffle 10 and the second baffle 20 are both provided with a connection seat 11 for installing the telescopic arm 30 and a connection plate 12 for installing the reinforcing diagonal brace 40; wherein the connection seat 11 of the first baffle 10 is hingedly connected to the telescopic arm 30, and the connection seat 11 of the second baffle 20 is detachably connected to the telescopic arm 30; the reinforcing diagonal brace 40 is detachably connected to the connection plate 12, respectively, and the length of the reinforcing diagonal brace 40 is made according to the distance between the first baffle 10 and the second baffle 20 and the connection method. The connection seat 11 is correspondingly arranged on the first baffle 10 and the second baffle 20, and similarly, the connection plate 12 is also correspondingly arranged on the first baffle 10 and the second baffle 20.

[0052] like Figure 1-Figure 2 As shown, one end of the telescopic arm 30 is disposed on the connecting seat 11 of the first baffle 10 through a third pin shaft (not shown), and the other end is fixed to the connecting seat 11 of the second baffle 20 through bolts.

[0053] Preferably, the first baffle 10 and the second baffle 20 are both provided with a plurality of connecting seats 11 and a plurality of connecting plates 12. The plurality of connecting seats 11 are arranged in the middle of the first baffle 10 and the second baffle 20, and the connecting plates 12 are evenly dispersed around the connecting seats 11. On the one hand, this design enables the telescopic arm 30 and the reinforcing diagonal brace 40 to stably support the first baffle 10 and the second baffle 20, so that each part of the first baffle 10 and the second baffle 20 is evenly stressed and not easily deformed; on the other hand, it is convenient to stagger the reinforcing diagonal brace 40 to prevent the telescopic arm 30 from obstructing the reinforcing diagonal brace 40.

[0054] In a preferred embodiment, Figure 1 As shown, the connection plates 12 are respectively arranged at the four corners of the first baffle 10 and the second baffle 20, and are staggered in pairs in the horizontal direction. In actual use, the reinforcing diagonal braces 40 located at the top are staggered with each other. Specifically, one end of the reinforcing diagonal brace 40 is connected to the connection plate 12 at one corner of the top of the first baffle 10, and the other end is connected to the connection plate 12 at the other corner of the top of the second baffle 20. Similarly, the reinforcing diagonal braces 40 located at the bottom are also staggered with each other.

[0055] like Figure 7 As shown, the connecting disk 12 in the present application is semicircular, and a plurality of connecting holes 121 are arranged circumferentially of the connecting disk 12. The reinforcing diagonal brace 40 is selectively connected to the connecting hole 121 by a clamp 122. When the reinforcing diagonal brace 40 is fixed to different connecting holes 121, different angles are formed between the reinforcing diagonal brace 40 and the first baffle 10 or the second baffle 20. During specific use, the reinforcing diagonal brace 40 can be selectively fixed to different connecting holes 121 according to the positional relationship between the first baffle 10 and the second baffle 20, so that the length it has can be connected to the first baffle 10 and the second baffle 20, and a staggered arrangement can be achieved at the same time.

[0056] Furthermore, if Figure 7 As shown, the clamp 122 is wedge-shaped, and the shape of the connecting hole 121 matches the clamp 122. Holes are also provided at both ends of the reinforcing brace 40. When in use, the clamp 122 only needs to be vertically passed through the connecting hole 121 and the hole to achieve effective connection between the reinforcing brace 40 and the first baffle 10 and the second baffle 20. At the same time, it is not easy to move, and the installation is simple and quick.

[0057] In some other embodiments of the present application, the reinforcing braces 40 may also be arranged in pairs in a staggered manner along the vertical direction. In a preferred embodiment, as shown in FIG. Figure 7 As shown, the present application has both the reinforcing diagonal braces 40 staggered in the horizontal direction and the reinforcing diagonal braces 40 staggered in the vertical direction.

[0058] like Figure 8As shown, in a specific embodiment, in order to facilitate transportation and movement, the length of the first baffle 10 is matched with the telescopic arm 30, so that the telescopic arm 30 will not protrude from the first baffle 10 when it is contracted and rotated around the third pin shaft (not shown) to fit the first baffle 10; a plurality of telescopic arms 30 hinged to the first baffle 10 are stored in the first baffle 10 at the same time, and can be moved and transferred synchronously with the first baffle 10, thereby reducing the overall volume, reducing the difficulty of transportation, and enabling the first baffle 10 to have a good storage function.

[0059] In the present application, the telescopic arm 30 includes a toothed rod 31 and a sleeve 32. One end of the sleeve 32 can be hinged to the first baffle 10, and one end of the toothed rod 31 is connected to the second baffle 20 by bolts; or one end of the toothed rod 31 can be hinged to the first baffle 10, and one end of the sleeve 32 is connected to the second baffle 20 by bolts, and there is no limitation here.

[0060] Furthermore, the first baffle 10 and the second baffle 20 are both provided with a reinforcement 14, and the connecting seat 11 is arranged on the reinforcement 14, so that the first baffle 10 and the second baffle 20 themselves have good rigidity, are not easily deformed under the side pressure of the trench soil, and have good stability.

[0061] When in use, the first baffle 10 is transported to the intended installation position, placed on one side of the groove so that it fits against the side wall, and the second baffle 20 is placed on the side wall on the other side of the groove, and the second baffle 20 is arranged opposite to the first baffle 10; the telescopic arm 30 is rotated to extend it in the direction of the second baffle 20, and the toothed rod 31 is manually stretched and its end is connected to the second baffle 20 through bolts; the handle 333 is turned to extend the length of the telescopic arm 30 until the first baffle 10 and the second baffle 20 hit the bottom groove side wall, and the limit piece 34 is rotated until it is engaged with the toothed belt 311, and the limit piece 34 is rotated to engage with the toothed belt 311. The positioning member 34 and the limiting hole 342 of the second connecting seat 11 form a through hole, and the limiting member 34 is fixed by installing bolts, thereby realizing the preliminary installation of the first baffle 10 and the second baffle 20; then the reinforcing diagonal brace 40 is installed, and the reinforcing diagonal brace 40 is fixed to the connecting hole 121 of the connecting plate 12 by the clamp 122, so that the reinforcing diagonal brace 40 is staggered to realize auxiliary support for the first baffle 10 and the second baffle 20; then another first baffle 10 is connected to the installed first baffle 10 through the tongue and groove 13, and the above steps are repeated to complete the overall support of the groove.

[0062] The advantages and positive effects of the utility model are:

[0063] (1) The first baffle and the second baffle can be quickly installed by setting a telescopic arm, which can effectively support the side wall of the groove, and the overall force is reasonable, which has good safety;

[0064] (2) By hingedly connecting the telescopic arm with the first baffle, the device can be applied to grooves of different widths and cross-sectional shapes, and has a wider range of applications;

[0065] (3) The overall structure is simple, easy to manufacture, and has low processing cost. It is easy to install, move, and use, which further saves costs.

[0066] The above is a detailed description of the embodiments of the utility model, but the contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
