Description

Technical Field

[0001] This utility model relates to the field of building engineering testing, and in particular to a monitoring device for the compaction degree of building foundation. Background Technology

[0002] Building construction refers to a series of technical work and completed engineering entities involved in the planning, surveying, design, construction, installation, and maintenance of new, renovated, or expanded buildings and structures. In building construction, foundation compaction refers to a foundation treatment method that uses external energy to rearrange soil particles and reduce porosity, thereby increasing the density and strength of the foundation soil.

[0003] During foundation compaction testing, staff will place the dynamic penetrometer at the monitoring location and then work in pairs. One person will hold the instrument while the other raises the drop hammer to the designated height and then releases it. The impact force of the drop hammer will drive the standard-sized probe into the foundation soil, and the number of hammer blows at each certain depth will be recorded.

[0004] The existing technology has the following drawbacks: In some existing equipment, when using the power penetrometer, the operator needs to frequently raise the hammer to the moving height by hand. Prolonged operation can easily cause hand fatigue for the operator. In addition, when the device is placed on the ground, it needs to be supported by hand, which may result in the device not being perpendicular to the ground, causing inaccurate monitoring results. Therefore, a foundation compaction monitoring device for building engineering is proposed to solve the above problems. Utility Model Content

[0007] The limiting mechanism includes a locking block, and a movable block is elastically connected to the inner wall of the front end of the locking block via a movable spring. The locking block is slidably connected to the top of the fixed block.

[0008] As a further description of the above technical solution:

[0009] The positioning component includes a bracket, the inner wall of which is threaded with an adjusting rod, and the bracket is slidably connected to the lower outer wall of the probe rod.

[0010] As a further description of the above technical solution:

[0014] As a further description of the above technical solution:

[0015] The top of the gravity block contacts the bottom of the limiting block, and the fixing block is fixedly connected to the outer wall of the probe rod.

[0016] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3This utility model provides an embodiment of a foundation compaction monitoring device for building engineering, comprising a probe rod 1, a gravity block 2 slidably connected to the outer wall of the probe rod 1, the gravity block 2 having a slot corresponding to the probe rod 1 to allow vertical movement of the gravity block 2, a pull rod 4 hinged to the outer wall of the gravity block 2 via a hinge rod 3, a fixing block 8 penetrating and slidably connected to the outer wall of the pull rod 4, two sets of long rods in the middle of the pull rod 4, and a slot corresponding to the long rods on the fixing block 8 to allow the pull rod 4 to move left and right. A limiting mechanism is provided at the top. A limiting block 11 is fixedly connected to the upper outer wall of the probe rod 1. The limiting block 11 serves as a prompt for the operator. When the limiting block 11 contacts the gravity block 2, it indicates that the drop distance of the gravity block 2 meets the requirements. A positioning component is provided on the lower outer wall of the probe rod 1. The limiting mechanism includes a locking block 5. A movable block 6 is elastically connected to the inner wall of the front end of the locking block 5 through a movable spring 7. The locking block 5 is slidably connected to the top of the fixed block 8. The fixed block 8 has a slot corresponding to the locking block 5, allowing the locking block 5 to move left and right.

[0035] Reference Figure 1 and Figure 6 The positioning component includes a bracket 9, with an adjusting rod 10 threadedly connected to the inner wall of the bracket 9. The inner wall of the bracket 9 is provided with a thread that matches the adjusting rod 10. Rotating the adjusting rod 10 allows the device to maintain a vertical angle with the ground. The bracket 9 is slidably connected to the lower outer wall of the probe rod 1. There are four sets of brackets 9 and adjusting rods 10 respectively. The adjusting rods 10 and the bracket 9 work together to support the device.

[0036] Reference Figures 3-5The outer wall of gravity block 2 is hinged to one end of hinge rod 3, and the other end of hinge rod 3 is hinged to the outer wall of pull rod 4. Since the length of hinge rod 3 is constant, when gravity block 2 moves downward with one end of hinge rod 3, the other end of hinge rod 3 moves to the left with pull rod 4. When pull rod 4 moves to the right with one end of hinge rod 3, the other end of hinge rod 3 moves upward with gravity block 2. The inner wall of the front end of locking block 5 is fixedly connected to one end of movable spring 7, and the other end of movable spring 7 is fixedly connected to the outer wall of movable block 6. When movable block 6 moves forward, movable spring 7 is compressed. During reset, the elastic force of movable spring 7 is used to reset movable block 6. The top end of the 2 contactes the bottom end of the limiting block 11. The fixed block 8 is fixedly connected to the outer wall of the probe rod 1. The bottom end of the gravity block 2 contacts the top end of the fixed block 8. The locking block 5 is inserted into the outer wall of the gravity block 2. The locking block 5 is provided with a protrusion. The gravity block 2 has a slot corresponding to the protrusion. The locking block 5 is initially inserted into the slot. The movable block 6 is slidably connected to the inner wall of the locking block 5. The locking block 5 has a slot corresponding to the movable block 6, allowing the movable block 6 to move back and forth. The movable block 6 is locked onto the top end of the fixed block 8. The fixed block 8 has two sets of slots corresponding to the movable block 6. The movable block 6 is initially locked into the first slot.

[0037] Working principle: When the device is needed, the operator can place it at the testing location and then rotate the adjusting rod 10 to keep the device perpendicular to the ground. Next, the operator can press the movable block 6 forward, which will compress the movable spring 7. When the movable block 6 separates from the first slot on the fixed block 8, the operator moves the movable block 6 and the locking block 5 to the right. When the locking block 5 separates from the slot on the gravity block 2, the movable block 6 aligns with the second slot on the fixed block 8. The operator then releases the movable block 6, and the elasticity of the movable spring 7 causes the movable block 6 to engage with the second slot. In the slot, the locking block 5 is limited. The worker can move the lever 4 to the right with his hand. The lever 4 moves the hinge rod 3 to the right. The other end of the hinge rod 3 moves the gravity block 2 upward. When the gravity block 2 contacts the limiting block 11, the worker releases the lever 4. Under its own weight, the gravity block 2 moves one end of the hinge rod 3 downward. The other end of the hinge rod 3 moves the lever 4 to the left. When the gravity block 2 falls onto the fixed block 8, the impact force will smash the probe rod 1 into the soil. The bracket 9 will slide along the outer wall of the probe rod 1, keeping its initial position unchanged.

[0038] When the device needs to be retracted, as the gravity block 2 falls onto the fixed block 8, the hand moves the locking block 5 and the movable block 6 to the left. When the locking block 5 inserts into the slot of the gravity block 2 to block the gravity block 2, the hand releases the movable block 6, allowing the movable block 6 to engage with the first slot of the fixed block 8, thus limiting the gravity block 2. Then, the hand moves the probe rod 1 upwards, and the bracket 9 slides down along the outer wall of the probe rod 1 to... Figure 1If you wish to continue using the device at the location shown, simply repeat the above steps.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
