Technical Field
The utility model relates to a building technical field specifically is a measuring device.
Background
The cast-in-situ bored pile is one of the common foundation pile forms in the building engineering, and has the function of transferring the load of an upper part building structure to a deep stable stratum and reducing the uneven settlement of the upper part building structure. The cast-in-situ bored pile is not cleaned in time in the drilling process, the hole wall collapses, or the reinforcement cage collides with the wall when the reinforcement cage is placed down, and the sediment is too thick due to the fact that concrete is not poured for too long time and the like. Therefore, the sediment thickness needs to be detected before the concrete is poured, and the concrete can be poured after the sediment thickness is qualified.
Regarding the detection of the thickness of the sediment at the bottom of the hole, 6.3.9 regulations in the technical Specification of building pile foundations (the industry Standard of the people's republic of China JGJ 94-2008):
1. the opposite end-bearing pile is not greater than 50 mm;
2. for the friction type pile, the thickness is not more than 100 mm;
3. and the pile with resistance to pulling and horizontal force is not greater than 200 mm. In order to solve the technical problem, the thickness of a sediment layer at the bottom of a pile needs to be limited, and the thickness of the sediment layer needs to be measured in construction, the Chinese patent application No. 202220731497.4 discloses a sediment detection device for a cast-in-situ bored pile, which comprises a measuring needle, a scale rope, a sedimentation barrel, a rope lifting mechanism and a connecting bracket, wherein the lower part of the scale rope is connected with the upper part of the rope lifting mechanism, and the lower part of the rope lifting mechanism is connected with the sedimentation barrel; the connecting bracket is connected with the upper part of the measuring needle, the connecting bracket is sleeved on the rope lifting mechanism, the sedimentation barrel consists of a barrel wall and a barrel bottom, the barrel wall is arranged on the barrel bottom, a through hole is arranged in the middle of the barrel bottom, and the lower part of the measuring needle penetrates through the through hole. The patent measurement method comprises the following steps: firstly, a tester lifts the whole device by hands and puts the device into a bored concrete pile hole, and when the tester feels that the weight of the device is reduced for the first time, the tester means that the measuring needle 1 reaches the bottom of sediment; when the weight of the device is sensed to be reduced for the second time, the weight means that the bottom of the sedimentation barrel 4 reaches the bottom of the sediment; the operator records the parameters of the rope in different states each time and calculates the thickness of the sediment; the patent relies on artificial feelings for judgment, which is obviously inaccurate; in addition, the original length of the rope cannot be guaranteed during lifting, and therefore, the measurement accuracy is inaccurate.
Other methods also comprise a sampling electric tool, for example, a structure that a motor is arranged on a floating plate and drives a rack to move downwards is adopted, but in construction, on one hand, a power supply is difficult to be arranged in a construction site, and on the other hand, the construction environment is not suitable for live-line measurement because of very insecurity.

Detailed Description
The utility model is described in detail with reference to the drawings, as shown in the figures, the utility model comprises a floating plate 4, a guide sleeve 42 is arranged above the floating plate, and the guide sleeve is fixed above the floating plate through a support rod 41; a directional lock 8 is fixed in the middle of the floating plate, a lifting rope 6 penetrates through the guide sleeve and the directional lock, and a measuring cone 5 is fixed at the lower end of the lifting rope. Due to the presence of water or slurry in the pile holes, a plurality of through holes 43 perpendicular to the floating plate are provided in the floating plate to reduce water buoyancy.
The floating plate is provided with a plurality of through holes vertical to the floating plate.
The lower part of the measuring cone 5 is in a sharp shape, so that the measuring cone can be conveniently inserted into a sediment layer;
the directional lock 8 comprises a rope sleeve 81 fixed with the floating plate, and a lifting rope passes through the rope sleeve; the lower end of the rope sling is provided with an opening 82; the lower end 84 of the locking lever 83 is tapered and corresponds to the opening; the middle position of the locking rod is coupled with the floating plate through a rotating shaft 86; a spring 85 is arranged between the lower end of the locking rod and the floating plate; when the lifting rope slides from top to bottom, the locking rod 83 does not limit the movement of the lifting rope, but when the lifting rope moves from bottom to top, the lower end 84 of the locking rod 83 is under the action of elastic force, so that the lifting rope is just clamped and prevented from moving upwards, and the descending length of the lifting rope is locked; the measuring personnel can judge the depth of the slag layer according to the length;
for the convenience of operation, a bracket 7 is arranged on the side part of the upper end of the pile hole, a supporting wheel 71 is arranged at the top end of a supporting arm 74 of the bracket, and the lifting rope 6 is wound around the supporting wheel and then is wound on a recovery wheel 73; the lower end of the bracket is fixed on the base 72; the recovery wheel is also fixed on the base.
Because the energy generated by measuring the weight of the cone 5 is inserted into the sediment layer during measurement, the weight of the measured cone can be adjusted according to different geological conditions and the depth of a pile hole, and the adjusting method comprises the following steps: the measuring cone body is of a hollow shell structure and is divided into an upper part and a lower part which are connected into a whole through threads. This allows for increased weight by loading a denser metal, such as lead metal, into the measurement cone;
for the purpose of measuring, the lifting rope has a scale 61.
The utility model discloses a use method is: the measuring cone body is withdrawn and then is in a state of abutting against the floating plate, and is lowered to the surface of the sediment layer at the bottom of the pile hole along with the lifting rope through a manual work or a supporting wheel on a bracket, and the floating plate floats on the surface of the sediment layer due to large area and light weight of the floating plate, and the measuring cone body continues to sink until reaching the bottom of the pile hole due to the gravity of the dead weight; when the lifting rope is changed from a vertical state (influenced by the weight of the measured vertebral body) to a nonlinear state, the lifting rope is lifted, and at the moment, the relative length generated by the measured vertebral body and the floating plate is the depth of a sediment layer; because the unidirectional lock is arranged, the relative position of the lifting rope and the floating plate cannot be influenced in the lifting process.
The one-way lock of the utility model can also adopt the commercially available products, such as the one-way lock used for the steel cable locking when the container is tied up.
