Description

Technical Field

[0001] The utility model relates to the technical field of soil collection devices, in particular to a foundation pit supporting device for civil construction. Background Art

[0002] During civil construction, a foundation pit is usually dug below the ground, and then the foundation is built in the foundation pit. Because some foundation pits are deep, in order to prevent the surrounding ground and buildings from collapsing, it is necessary to install support devices on the slope of the foundation pit.

[0003] When the existing slope protection device is in use, the baffle contacts the foundation pit wall and is supported by the support rod to achieve the protection effect. However, in actual use, due to the influence of the geographical environment and the external environment, the soil on the foundation pit wall may flow. At this time, the flow of soil will quickly exert pressure on the baffle. Some of the soil on the foundation pit wall will also carry some stones, which will cause damage to the baffle. In addition, the soil pressure at this time will also pose a risk of foundation pit collapse.

[0004] Therefore, a civil construction foundation pit supporting device is provided to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology, and to propose a foundation pit supporting device for civil construction.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The foundation pit support device for civil construction includes support plates and:

[0008] Multiple groups of partitions are fixedly connected to the support plate, and the multiple groups of partitions divide the support plate into spaces of the same size;

[0009] Multiple groups of compression plates are slidably connected in the spaces on the support plate;

[0010] A sliding rod is fixedly connected to the anti-compression plate, and one end of the sliding rod away from the anti-compression plate passes through the supporting plate;

[0011] A spring member is sleeved on the sliding rod, and two ends of the spring member are respectively connected to the anti-pressure plate and the supporting plate;

[0012] The push-type switch is arranged on the support plate. When external soil impacts the pressure-resistant plate, the sliding rod will slide and move accordingly, thereby squeezing the push-type switch.

[0013] In order to facilitate installation, preferably, a mounting rod is fixedly connected to the support plate, and the push-type switch is fixedly connected to the mounting rod.

[0014] Preferably, the through ends of the plurality of groups of sliding rods located on the same horizontal plane are all fixedly connected with connecting plates, and the push-type switches can be squeezed through the connecting plates.

[0015] In order to quickly provide a prompt, preferably, a sliding groove is provided on the installation rod, a sliding plate is slidably connected in the sliding groove, and the sliding plate is fixedly connected to the multiple groups of connecting plates.

[0016] In order to reduce the intrusion of soil, preferably, a top baffle is fixedly connected to the top of the supporting plate.

[0017] Preferably, a mounting block is fixedly connected to the support plate, a support rod is rotatably connected to the mounting block, and a support plate is fixedly connected to one end of the support rod away from the mounting block.

[0018] Compared with the prior art, the present invention provides a foundation pit support device for civil construction, which has the following beneficial effects:

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example 1:

[0027] Reference Figure 1-4 The foundation pit support device for civil construction includes a support plate 1, and also includes: multiple groups of partitions 101, all of which are fixedly connected to the support plate 1, and the multiple groups of partitions 101 divide the support plate 1 into spaces of the same size; multiple groups of pressure plates 2, all of which are slidably connected to the spaces on the support plate 1; a sliding rod 201, fixedly connected to the pressure plate 2, and the end of the sliding rod 201 away from the pressure plate 2 passes through the support plate 1; a spring member 202, sleeved on the sliding rod 201, and the two ends of the spring member 202 are respectively connected to the pressure plate 2 and the support plate 1; a push-type switch 3, which is arranged on the support plate 1, and when external soil impacts the pressure plate 2, the sliding rod 201 will slide and move accordingly, thereby squeezing the push-type switch 3, and a mounting block 401 is fixedly connected to the support plate 1, and a support rod 402 is rotatably connected to the mounting block 401, and a support plate 403 is fixedly connected to the end of the support rod 402 away from the mounting block 401.

[0028] When installing this device, the anti-pressure plate 2 in the device is pressed against the foundation pit wall. At this time, the spring part 202 is in a normal state and is not compressed, and the support plates 1 are arranged tightly to avoid large gaps between the support plates 1. At the same time, the anti-pressure plate 2 is supported by the support rod 402 and the support plate 403, and a push-type switch 3 is set on the end of each sliding rod 201 away from the anti-pressure plate 2.

[0029] When in use, the pressure plate 2 in the device will press against the wall of the foundation pit to provide daily protection. At the same time, if the soil of the foundation pit wall flows, the soil will impact the pressure plate 2. At this time, the pressure plate 2 will bear the pressure caused by the impact of the soil and move synchronously. At the same time, the spring part 202 is compressed to absorb the pressure. At the same time, the sliding rod 201 will move synchronously, thereby squeezing the push-type switch 3. At this time, only an alarm needs to be set up on the construction site. If the push-type switch 3 sends a signal, the alarm will sound and nearby staff can evacuate quickly. Professionals will go to the site and know the actual position of the soil flow based on the position of the moving sliding rod 201, and then detect whether the foundation pit will collapse.

[0030] The spring member 202 in the present device is a large spring, which requires a large force to be compressed and deformed, thereby preventing the sliding rod 201 from moving due to a small force.

[0031] Example 2:

[0032] Reference Figure 1-4 The civil construction foundation pit support device is basically the same as that of Example 1, and furthermore: a mounting rod 102 is fixedly connected to the support plate 1, and the push-type switch 3 is fixedly connected to the mounting rod 102. The through ends of multiple groups of sliding rods 201 located on the same horizontal plane are fixedly connected with connecting plates 203, and the push-type switch 3 can be squeezed through the connecting plates 203. A sliding groove 1021 is provided on the mounting rod 102, and a sliding plate 204 is slidably connected in the sliding groove 1021. The sliding plate 204 is fixedly connected to the multiple groups of connecting plates 203.

[0033] By setting the connecting plate 203 and the sliding plate 204, only one push-type switch 3 is needed during installation. During use, if the foundation pit collapses, any one of the sliding rods 201 slides, which will cause the connecting plate 203 to move, and then drive the sliding plate 204 to move, thereby squeezing the push-type switch 3 and issuing an alarm.

[0034] Such an arrangement can reduce the number of push switches 3 and reduce the occurrence of workers accidentally touching the switches.

[0035] Example 3:

[0036] Reference Figure 1-3 The foundation pit supporting device for civil construction is basically the same as that of Example 1, and furthermore, a top baffle 103 is fixedly connected to the top of the supporting plate 1.

[0037] The provision of the top baffle 103 can reduce the amount of soil flowing through the top into the gap between the support plate 1 and the pressure plate 2, thereby avoiding the situation where the pressure plate 2 is restricted and unable to move.

[0038] The utility model adopts the arrangement of the pressure plate 2 and the spring member 202. When the soil on the foundation pit wall flows into the foundation pit, the spring member 202 can absorb the force generated by the impact to a certain extent. At the same time, through the arrangement of the sliding rod 201 and the push-type switch 3, when the pressure plate 2 is displaced, a signal can be quickly sent to warn the surrounding staff to evacuate quickly, thereby avoiding personal injury caused by foundation pit collapse.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
