Description

Technical Field

[0001] The utility model is a measuring tool for the overfilling height of a pile foundation, belonging to the technical field of construction. Background Art

[0002] Cast-in-place piles are a type of pile foundation. First, a hole is drilled on the construction site. When the required depth is reached, the steel bars are placed and poured with concrete. For unstable soil, it is very difficult to construct reinforced concrete retaining walls, so steel casings are used to protect the bored piles to prevent the hole from collapsing and avoid affecting the construction progress and safety. Muddy water is poured into the steel casing to provide balanced support for the steel casing. When pouring concrete, it is necessary to insert a spigot into the pile hole where muddy water exists, so that the concrete flows to the bottom of the pile hole under the action of the spigot. Then the muddy water is squeezed out by the concrete. Affected by the obstruction of the muddy water, the over-filling elevation of the pile foundation is judged by the workers based on their experience, resulting in a large over-filling error, which affects the construction quality of the pile foundation.

[0011] Beneficial effects of the utility model:

[0012] 1. The semicircular first water storage cover and the second water storage cover are sleeved on the upper end of the steel casing, and then the first water storage cover and the second water storage cover are connected by connecting screws, so that the cylindrical structure formed by the first water storage cover and the second water storage cover is restricted on the steel casing. When the concrete flows into the bottom of the pile hole by means of inserting a pipe to guide the concrete, the muddy water in the pile hole overflows from the upper edge of the steel casing under the pressure of the concrete, and the overflowed muddy water flows into the space formed by the first water storage cover, the second water storage cover and the steel casing. After opening the ball valve, the muddy water flows into the space formed by the first water storage cover, the second water storage cover and the steel casing. Water flows into the water tank through the drainage pipe. When a certain amount of muddy water is collected in the water tank, close the ball valve and open the drain valve to drain the muddy water in the water tank. Repeat the above operation and record the number of times the muddy water in the water tank is drained. Since the inner diameter of the pile hole is constant, the volume of the muddy water discharged through the water tank is calculated. According to volume = bottom area * height, the elevation of the concrete pouring in the pile hole is calculated. The elevation of the pile foundation over-tank is measured by the volume of the discharged muddy water to avoid large over-pouring errors.

[0013] 2. Insert poles into the vertical holes on the four supports, and then adjust the relative positions of the four poles and the supports so that the chassis at the lower ends of the four poles are in contact with the ground and the water tank is in a horizontal state. At this time, the four poles can achieve balanced support for the water tank. On the one hand, the water tank can be placed on an uneven ground, and on the other hand, there is no need to level the ground where the water tank is placed. BRIEF DESCRIPTION OF THE DRAWINGS
