Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pile foundation construction tooling, and more specifically relates to a concrete surface measuring tool for pouring concrete slurry. Background Art
[0002] During the construction of bored cast-in-place piles, underwater concrete needs to be poured under the mud, and the top surface of the concrete needs to be poured to a predetermined elevation to avoid insufficient pouring height, resulting in a "bad pile head", or excessive pouring height, resulting in material waste and difficulty in demolition.
[0003] The traditional method is to use a measuring rope to measure the top surface of concrete, but this method is not accurate. The measuring rope may be blocked by sediment, mud, steel cages, etc. The surveyors mistakenly think that fresh concrete has been detected, causing the concrete surface to be lower than the control elevation and produce a "bad pile head". Moreover, the measuring rope is not sensitive to the detection of concrete. The detection depth is often lower than the fresh concrete surface, causing the concrete surface to exceed the control elevation, resulting in waste of concrete and difficulty in demolition. Utility Model Content
[0004] The utility model aims to provide a concrete surface measuring tool for pouring concrete slurry, so as to solve the technical problem that it is difficult to accurately measure the concrete top surface elevation during the construction process of bored piles in the prior art.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is: to provide a concrete surface measuring tool for pouring concrete mud, including a scoop basket and a handle, the scoop basket is a conical basket structure for holding stones in concrete; the handle is connected to one end of the scoop basket.
[0006] In combination with the above technical solution, in a possible implementation, the scoop basket includes an annular ring and a plurality of fence rods, the annular ring is perpendicular to and fixedly connected to the handle, the plurality of fence rods are arranged at intervals, and one end of each of the fence rods is connected to the lower end of the handle and the other end is connected to the annular ring to form a conical basket structure.
[0007] In combination with the above technical solution, in a possible implementation, the handle is a detachable multi-section structure.
[0008] In combination with the above technical solution, in a possible implementation manner, a ruler is provided on the handle.
[0009] In combination with the above technical solution, in a possible implementation, the concrete surface measurement tool for pouring concrete slurry further includes a density ball, which is connected to the lower end of the handle and is located above the scoop basket.
[0010] In combination with the above technical solution, in a possible implementation manner, the density ball is a hollow spherical, hemispherical or box-shaped structure.
[0011] In combination with the above technical solution, in a possible implementation, the density ball is slidably connected to the handle via a sliding sleeve, and a fastener is provided on the sliding sleeve to fasten the density ball to the handle.
[0012] In combination with the above technical solution, in a possible implementation manner, an opening is provided on the density ball, and a sealing cover is provided on the opening.
[0013] In combination with the above technical solution, in a possible implementation, a vibrator is provided on the scoop basket, a wire connected to the vibrator is provided on the handle, and a control switch is provided on the wire.
[0014] In combination with the above technical solution, in a possible implementation method, a number of fasteners are arranged at intervals on the wire, and the wire is connected and fixed to the handle through the fasteners; a battery is provided at the upper end of the handle, and the wire is connected to the battery to power the vibrator; the control switch and the battery are both connected and fixed to the handle through fasteners.
[0015] The beneficial effect of the concrete surface measuring tool for pouring concrete slurry provided by the utility model is that compared with the prior art, when the utility model is used, the operator puts the scoop basket into the hole through the handle, operates the scoop basket to be lowered to the elevation position according to the length of the handle and the depth of the lowering, and moves the scoop basket up and down at the elevation position. Since the scoop basket is a conical basket structure, and the fresh concrete has good fluidity, and the density and viscosity are also greater than the slurry, if the scoop basket contacts the concrete surface and gradually extends under the concrete surface, the operator will obviously feel a continuous sense of blockage, so that it can be roughly judged that the concrete has been poured to the elevation, and then the handle is lifted upward to lift the scoop basket out of the hole. If a large number of stones in the concrete are obviously present in the scoop basket, it indicates that the concrete has been poured in place. If no stones in the concrete appear in the scoop basket, it indicates that the concrete has not been poured in place. In this way, the top surface of the concrete can be measured more accurately, avoiding the situation that the concrete surface is lower than the control elevation to produce a "bad pile head", or the concrete surface exceeds the control elevation, resulting in a waste of concrete and difficulty in demolition. The structure is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The concrete surface measuring tool for concrete slurry pouring provided by the utility model is now described.
[0029] like Figure 1 As shown, the first embodiment of the utility model provides a concrete surface measuring tool for pouring concrete slurry, which includes a scoop basket 10 and a handle 20. The scoop basket 10 is a conical basket structure for containing stones in concrete; the handle 20 is connected to one end of the scoop basket 10.
[0030] Compared with the prior art, the concrete surface measuring tool for concrete slurry pouring provided in this embodiment has a different structure. When in use, the operator lowers the basket 10 into the hole through the handle 20, lowers the basket 10 to the elevation position according to the length of the handle and the depth of the lowering, and moves the basket 10 up and down at the elevation position. Since the basket 10 is a conical basket structure, and the fresh concrete has better fluidity, and its density and viscosity are greater than the slurry, if the basket 10 contacts the concrete surface and gradually extends below the concrete surface, the operator will obviously feel a continuous sense of obstruction, so that the operator can It can be roughly determined that the concrete has been poured to the elevation, and then the handle 20 is lifted upward to lift the basket 10 out of the hole. If a large number of stones in the concrete are obviously seen in the basket 10, it indicates that the concrete has been poured in place. If no stones in the concrete are seen in the basket 10, it indicates that the concrete has not been poured in place. In this way, the top surface of the concrete can be measured more accurately, avoiding the situation where the concrete surface is lower than the control elevation to produce a "bad pile head", or the concrete surface exceeds the control elevation, resulting in a waste of concrete and difficulty in demolition. The structure is simple and easy to use.
[0031] like Figure 2 As shown, the utility model provides a specific implementation method based on the first implementation method as follows.
[0032] The handle 20 is a detachable multi-section structure, so that it is convenient for disassembly and transportation under the premise of meeting the use depth. Adjacent sections can be connected by a threaded structure or a snap-on structure to ensure connection strength while facilitating disassembly.
[0033] A ruler is provided on the handle 20 to facilitate observation of the immersion depth during use, thereby quickly determining the elevation of the concrete. The ruler may be a marking structure carved on the handle 20, such as a groove, a hole, a marking buckle, etc., or may be a hard or soft ruler with a scale fixed on the handle 20.
[0034] In order to prevent the entire tool from slipping out of the hand and falling into the hole during use, a hanging ring can be provided on the handle 20, and a safety rope can be hung on the hanging ring.
[0035] Specifically, the scoop basket 10 includes an annular ring 11 and a plurality of fence rods 12. The annular ring 11 is perpendicular to and fixedly connected to the handle 20. The plurality of fence rods 12 are arranged at intervals, and one end of each of the fence rods is connected to the lower end of the handle 20 and the other end is connected to the annular ring 11 to form a conical basket structure.
[0036] The concrete surface measuring tool for pouring concrete slurry further comprises a density ball 30, which is connected to the lower end of the handle 20 and is located above the basket 10. The density ball 30 can be a hollow spherical, hemispherical or box-shaped structure.
[0037] On the one hand, the density ball 30 can be used to adjust the density of the entire tool to be roughly the same as that of the mud, that is, slightly smaller than the density of the concrete. When in use, the entire device can be lowered into the mud so that the density ball 30 is located at the elevation and the scoop basket 10 is located below the elevation. After the concrete is poured at the elevation, the entire tool will generate an upward force that is easily felt by the operator. Moreover, since the pouring of concrete has a certain inertia, part of the concrete will enter the scoop basket 10. After the operator feels the upward force, he can lift the handle 20 and judge whether the scoop basket 10 has stones to determine whether it has been poured to the elevation.
[0038] The density ball 30 is slidably connected to the handle 20 through a sliding sleeve 31, and a fastener 32 is provided on the sliding sleeve 31 to fasten the density ball 30 to the handle 20. In this way, the position of the density ball 30 on the handle 20 can be conveniently adjusted, thereby adjusting the depth of the basket 10 to better scoop out stones in the concrete. Specifically, the fastener 32 can be a fastening bolt, a pin, or the like.
[0039] The density ball 30 is provided with an opening, and the opening is provided with a sealing cover 33. Stones, mud and other materials can be put into the density ball 30 through the opening to adjust the overall density, and the opening can be closed by the sealing cover 33 to prevent mud from entering the density ball 30 during use.
[0040] A vibrator 40 is provided on the scoop basket 10 , a wire 41 connected to the vibrator 40 is provided on the handle 20 , and a control switch 42 is provided on the wire 41 to facilitate an operator to control the opening and closing of the vibrator 40 .
[0041] By setting the vibrator 40, the operator can start the vibrator 40 after inserting the scoop basket 10 into the fresh concrete to vibrate the concrete, so that the concrete can enter the scoop basket 10 and more stones can be settled in the scoop basket 10 to facilitate sampling. At the same time, during the lifting process of the scoop basket 10, the vibrator 40 can be used to vibrate the scooped concrete so that small particles therein are washed out by the mud, thereby reducing the possibility of stones falling during the lifting process and the difficulty in observing the stones after lifting.
[0042] Furthermore, a plurality of fasteners 43 are arranged at intervals on the wire 41, and the wire 41 is connected and fixed to the handle 20 by the fasteners 43 to prevent the wire 41 from being hooked on the steel cage and to facilitate disassembly for use with handles 20 of different lengths; a battery 44 is provided at the upper end of the handle 20, and the wire 41 is connected to the battery 44 to power the vibrator 40; the control switch 42 and the battery 44 are both connected and fixed to the handle 20 by the fasteners 43.
[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
