Abstract
Description
Technical Field
[0001] The invention relates to the field of building construction, in particular to a drainage structure for low-water-level water accumulation on a cap and a method for clearing the structure. Background Art
[0002] The foundation of a building generally includes independent caps, caps, and rafts. The cap steel bars are generally designed in multiple rows and the steel bars are densely arranged. Since foundation construction sometimes involves outdoor work, water will accumulate in the foundation cap when it rains. If the accumulated water in the cap is not removed in time, the presence of water in the cap will indirectly change the concrete mix ratio during concrete pouring, which will subsequently seriously reduce the concrete's impermeability and tensile strength, and easily cause concrete cracking and leakage.
[0003] At present, in order to remove the accumulated water in the pedestal, a water pump is generally used to centrally drain the water in the pedestal before pouring concrete. However, since the bottom plate of the pedestal is flat, when the depth of the accumulated water in the pedestal is shallow, the water pump cannot effectively absorb the water at the bottom. For this part of the low water level, manual cleaning is currently widely used, which is time-consuming and labor-intensive, and the water removal effect is not good. Summary of the invention
[0004] The purpose of the present invention is to overcome the above-mentioned defects and to provide a drainage structure for low-water-level water accumulation on a cap and a method for removing the same.
[0005] In order to achieve the above object, the present invention is achieved in the following ways: A drainage structure for low-water accumulation on a pedestal comprises a cushion layer, a pedestal body and foundation piles at the bottom of the pedestal body. A water collection well is arranged at the level where the cushion layer is located, and drainage equipment leading to the outside is arranged in the water collection well.
[0006] In the drainage structure for low-water-level water accumulation on the above-mentioned foundation, a slope surface is arranged on the cushion layer, and the slope surface is inclined toward the water collection well.
[0007] The drainage structure for low water level accumulation on the above-mentioned pedestal has a slope of 0.5% on the slope of the cushion layer.
[0008] In traditional practice, the foundation cushion of the pedestal is usually only leveled, but in the pedestal cushion structure proposed in the present invention, a water collection well is reserved on the pedestal cushion, and the cushion is sloped toward the water collection well, so as to facilitate the collection of water in the pedestal. In this way, it is beneficial to use gravity to naturally drain or collect low-level water.
[0009] Furthermore, the present invention also proposes a method for clearing water accumulation on a cap based on the above drainage structure, which specifically includes: Step 1: Familiarize yourself with the project drawings, count the forms and quantities of the project caps, and determine the construction arrangements for the cap cushion layer; Step 2: Determine the location and size of the water collection wells corresponding to different types of caps; Step 3: Position the foundation and complete the foundation excavation; Step 4: Carry out the construction of the foundation cushion layer. According to the determined location of the water collection well, use the wooden template to make the water collection well template box, and position it according to the determined location of the water collection well. The elevation of the cushion layer is the same as the elevation of the upper mouth of the water collection well. After the thickness of the cushion layer is expanded according to the size of the water collection well, a water collection well foundation pit of corresponding size is excavated in the foundation. The template is fixed with a steel support around it to prevent the template box from deflecting and ensure the accuracy of the size. Step 5: When pouring the cushion layer, set a slope of 5‰ towards the water collection well; when excavating the cap, the elevation of the cushion layer concrete is controlled by elevation piles. Before pouring the cushion layer concrete, calculate the slope of the water collection well and adjust the height of the elevation control piles synchronously. When pouring concrete, pour from high to low, and use the elevation piles to control the slope of the finished surface to complete the slope finding; Step 6: When there is a lot of water accumulated in the foundation, use a submersible pump to pump out the water first, and then use a siphon pump to drain the water in the bottom layer or the collection well.
[0010] In the above-mentioned method for clearing low-water-level water accumulation in a pedestal, a water collection well is arranged in a pedestal structure, and the size of the water collection well is W300*L300*D200.
[0011] In traditional practice, when the water in the foundation is deep, a submersible pump is generally used for drainage. However, when the water is shallow, the submersible pump cannot function. At this time, manual cleaning with tools is often used, or the deadweight of concrete is used to discharge the water during concrete pouring. However, the above methods are time-consuming and labor-intensive, and the effect is not good, resulting in waste of manpower and material resources and loss of concrete performance. In the method for removing water from the foundation proposed in the present invention, a water collection well is used to collect the water on the foundation. When the water on the foundation is shallow, a siphon pump is directly used at the water collection well to discharge the water, which can effectively deal with the problem of water on the foundation.

In this way, when the water in the pedestal is deep, a submersible pump is generally used for drainage. However, when the water is shallow, the submersible pump cannot function. At this time, manual cleaning with tools is often used, or the deadweight of concrete is used to discharge the water during concrete pouring. However, the above-mentioned treatment methods are time-consuming and labor-intensive, and the effects are not good, resulting in waste of manpower and material resources and loss of concrete performance. In the method for removing water from the pedestal proposed in the present invention, a water collection well is used to collect the water on the pedestal. When the water on the pedestal is shallow, a siphon pump is directly used at the water collection well to discharge the water, which can effectively deal with the problem of water on the pedestal.
