Construction joint waterproof construction method for combined design of water stop steel plate and anti-crack steel bars

Abstract

The invention relates to a construction joint waterproof construction method for combined design of a water stop steel plate and anti-crack steel bars of basement floors. The construction joint waterproof construction method is characterized by comprising the following steps of a, digging a foundation bottom plate pit to the designed elevation; b, pouring a concrete cushion layer at the bottom ofthe pit; c, laying a pre-laid anti-sticking waterproof coiled material; d, binding an anti-crack steel bar net; e, pouring waterproof concrete in an inclined pit; f, binding the reinforcing steel barson the left side of a construction joint; g, mounting a steel plate waterstop at the position of a concrete bottom plate; h, mounting a formwork at the construction joint; i, pouring waterproof concrete on the left side of the construction joint; j, pouring a concrete cushion layer of the bottom plate on the right side of the construction joint; and k, pouring waterproof concrete on the bottom plate of the right side of the construction part. The construction joint waterproof construction method for combined design of the water stop steel plate and the anti-crack steel bars has the advantagesthat the water stop steel plate and the anti-crack steel bars are combined to form a water stop area, so that the concrete has the anti-crack water stop function, the waterproof effect is good, an additional external anti-crack waterproof layer is arranged at the construction joint of the bottom plate, and the flow path of water is increased.

Description

technical field [0001] The invention relates to a waterproof construction method for construction joints, in particular to a waterproof construction method for construction joints designed in combination with waterproof steel plates and crack-resistant steel bars in a basement. Background technique [0002] For super-long basements or special underground equipment foundations, underground waterproofing is the focus of design and construction. At present, the stamping special structural equipment foundations of the stamping workshops of major automobile manufacturers are basically in a state of water seepage, and in severe cases, it may even affect the production of automobiles. In the design drawings, the design institute often adopts the method of rubber waterstop expansion joints to solve the problem of expansion and deformation of super-long underground structures, so as to theoretically solve the waterproof problem of super-long underground structures. However, the rubb...

Problems solved by technology

However, the practice of rubber waterstops is often difficult to obtain better product protection during the construction process, resulting in damage to the rubber waterstop

After the underground structure is formed, it will basically be in a state of water leakage, which is extremely difficult to repair and maintain, which has caused great problems for the use of the underground structure

It is difficult to achieve a good water-stop effect if the water-stop steel plate is used alone. The design of the post-casting belt in the basement often adopts the combination of an additional steel frame and a water-stop steel plate, but often the leaking part of the basement occurs at the post-casting belt. The main reason is that the concrete on both sides of the post-pouring belt produces micro-cracks, which weakens the bonding between the water-stop steel plate and the concrete, and makes water flow around the water-stop steel plate and leak into the interior

[0003] Therefore, there are above-mentioned inconveniences and problems in the combined structure of the known additional steel frame in cooperation with the waterproof steel plate.
