Description

Technical Field

[0001] The utility model relates to the technical field of cast-in-place pile construction equipment of building engineering, in particular to a measuring device for measuring the pouring position of a cast-in-place pile. Background Art

[0002] Cast-in-place piles are reinforced concrete piles made by drilling holes in place and pouring concrete. Cast-in-place piles have the advantages of no vibration, no soil squeezing, low noise, and are suitable for use in densely built urban areas. Cast-in-place piles are widely used in construction.

[0003] During the pouring construction of bored piles, it is first necessary to preset the pouring position of the bored piles, and then the construction workers pour into the preset pouring position of the bored piles to complete the pouring construction of the bored piles.

[0004] However, in the above construction process, due to insufficient fluidity of concrete or too fast pouring speed, a slurry layer may appear at the top of the pile (the bottom of the pile is a concrete stone layer, and the slurry layer is a liquid layer). Due to the turbidity of the slurry layer and low visibility, construction workers cannot accurately know whether the concrete pouring has reached the preset bored pile pouring position by naked eyes or by using a measuring rope method. At the same time, it is currently impossible to use more accurate instruments and equipment to measure whether the concrete has been poured to the exact bored pile pouring position.

[0005] This leads to the first defect: the floating slurry layer will cause the concrete to not be poured to the correct position (the preset pouring position of the bored pile);

[0006] The second defect: the existence of the slurry layer reduces the base bearing capacity of the top of the bored pile (due to the existence of the slurry layer, the height of the slurry layer cannot be determined, resulting in two problems during the subsequent top removal construction. First, the slurry layer is either not completely removed, resulting in the existence of the slurry layer; second, the slurry layer is completely removed, but the designed height of the bored pile does not meet the standard).

[0007] Therefore, in order to avoid the influence of the floating slurry layer and accurately measure the pouring position of the bored piles, so that the construction workers can pour the piles to the preset pouring position, there is an urgent need for a concrete stone bailing detector for measuring the pouring position of the bored piles on the market. Utility Model Content

[0008] The purpose of the utility model is to overcome the above-mentioned defects in the prior art and provide a measuring device for measuring the pouring position of bored piles, which includes a lower probe rod for construction personnel to hold, and a soil and rock salvage device is lowered to a preset pouring position. At this time, if the soil and rock salvage device does not salvage concrete soil and rocks, it proves that the pouring position at this time is in a floating slurry layer, and it is necessary to continue pouring concrete soil and rocks; if the soil and rock salvage device salvages concrete soil and rocks, it proves that the pouring position at this time has been poured and has reached the preset pouring position. At this time, the construction personnel stop construction, and the pouring position of the bored pile can be effectively and accurately measured through this structure.

[0009] To achieve the above-mentioned purpose, the utility model provides a measuring device for measuring the pouring position of bored piles, comprising a lower probe rod and a soil and rock salvage device installed at the bottom of the lower probe rod, the soil and rock salvage device comprising a support plate installed at the bottom of the lower probe rod and a plurality of support rods arranged around the support plate, the plurality of support rods presenting an inclined structure that is narrow at the bottom and wide at the top, a plurality of support rods having a fixing ring arranged around the top, and a soil and rock scooping area being formed between the support plate, the plurality of support rods and the fixing ring.

[0010] Preferably, the lower probe rod includes a first rod shaft and a first external thread arranged on the top of the first rod shaft.

[0011] Preferably, it also includes an extension rod threadedly connected to the lower probe rod.

[0012] Preferably, the extension rod includes a second rod shaft, a second external thread arranged at the top of the second rod shaft, an outer sleeve arranged at the bottom of the second rod shaft, and an internal thread arranged on the inner wall of the outer sleeve and threadably connected to the first external thread of the lower probe rod.

[0013] Preferably, the supporting plate is a circular plate.

[0014] Preferably, a plurality of the support rods are arranged around the outer edge of the top surface of the support plate.

[0015] Preferably, a retaining stone opening which is narrow at the bottom and wide at the top and is used for allowing liquid on the floating slurry layer to flow out is formed between two adjacent support rods of the plurality of support rods, and the retaining stone opening is communicated with the retaining stone opening.

[0016] Preferably, the support rod is cylindrical.

[0017] Preferably, the fixing ring is arranged on the inner side of the top of a plurality of support rods.

[0018] Preferably, the fixing ring is made of sheet iron material.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] 1. The lower probe rod provided in the utility model is used for construction workers to hold, which is convenient to use.

[0021] 2. The soil and rock salvage device provided in the utility model goes down to a preset pouring position. At this time, if the soil and rock salvage device does not salvage concrete soil and rocks, it proves that the pouring position at this time is in a slurry layer (because there is no concrete stone layer entering the soil and rock salvaging area, and the liquid layer of the slurry layer flows out from between two adjacent support rods). At this time, it is necessary to continue pouring concrete soil and rocks. If the soil and rock salvage device salvages concrete soil and rocks (there is a concrete stone layer entering the soil and rock salvaging area and it cannot flow out from between two adjacent support rods), it proves that the pouring position at this time has been poured and has reached the preset pouring position. At this time, the construction personnel stop the construction, and it is simple to use.

[0022] 3. In summary, the measuring device for measuring the pouring position of bored piles of the utility model can effectively and accurately measure the pouring position of bored piles, is simple and convenient to use, has fast measurement and low manufacturing cost. After the construction is completed, the top of the preset pouring position is removed, thereby eliminating the influence of the floating slurry layer on the bored piles, while meeting the design height of the bored piles.

[0033] The lower probe rod 1 includes a first rod body 11 and a first external thread 12 provided at the top of the first rod body 11. The bottom of the first rod body 11 is integrally formed with the top of the support plate 21. The lower probe rod 1 is used to facilitate construction workers to hold and lower the soil and rock salvage device 2 to a preset cast-in-place pile pouring position.

[0034] The embodiment of the utility model provides a measuring device for measuring the pouring position of a bored pile, which also includes an extension rod 3 threadedly connected to the lower probe rod 1. The number of the extension rod 3 is at least one, and the number is not limited in the utility model.

[0035] The extension rod 3 includes a second rod shaft 31, a second external thread 32 provided at the top of the second rod shaft 31, a jacket portion 33 provided at the bottom of the second rod shaft 31, and an internal thread 34 provided on the inner wall of the jacket portion 33 and threadedly connected to the first external thread 12 of the probe rod 1. The second external thread 32 of the extension rod 3 can be threadedly connected to the internal thread 34 of another extension rod 3, so that the rod shaft for construction personnel to hold and probe becomes longer.

[0036] The support plate 21 is a circular plate. A plurality of support rods 22 are arranged around the outer edge of the top surface of the support plate 21. The plurality of support rods 22 are integrally formed with the circular plate by welding.

The retaining stone opening 25 is a downward triangle.

[0038] The support rod 22 is cylindrical.

[0040] The structural design advantages of the earth and rock salvage device 2 of the embodiment of the utility model are:

[0041] The soil and rock salvage device 2 has an umbrella-shaped structure. First, the structure is stable. Second, it is convenient for concrete soil and rocks to enter from the large opening at the top of the soil and rock salvaging area 24. At the same time, the inverted triangular narrow opening of the retaining stone opening 25 prohibits concrete soil and rocks from flowing out. Third, it is convenient for downward exploration and insertion. Fourth, the retaining stone opening 25 allows the liquid in the slurry layer to flow out.

[0042] The working principle of a measuring device for measuring the pouring position of a bored pile in an embodiment of the utility model is as follows: first, the construction personnel hold the lower probe rod 1 to probe downward; second, when the soil and rock salvage device 2 probes downward to the preset pouring position, if the soil and rock salvage device 2 does not salvage concrete soil and rocks, it proves that the pouring position at this time is in the floating slurry layer because there is no concrete stone layer entering the soil and rock salvage area 24, and the liquid layer of the floating slurry layer flows out from the retaining stone opening 25 between the two adjacent support rods 22. At this time, it is necessary to continue pouring concrete soil and rocks. If the soil and rock salvage device 2 salvages concrete soil and rocks (there is a concrete stone layer entering the soil and rock salvage area 24, and it cannot flow out from the retaining stone opening 25 between the two adjacent support rods 22), it proves that the pouring position at this time has been poured and has reached the preset pouring position. At this time, the construction personnel stop construction. After the bored pile is formed, the top of the preset pouring position is removed, thereby eliminating the influence of the floating slurry layer on the bored pile, while meeting the design height of the bored pile.
