Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the examples.

[0036] A FS101, FS102 underground rigid composite waterproof construction method, the specific construction steps are as follows:

[0037] Step 1, Excavating the Foundation Pit

[0038] Step two, concrete cushion construction

[0039] Cushion construction shall be carried out after foundation pit inspection is completed. The concrete cushion of FS102 compact waterproof concrete structure floor shall have a strength grade of not less than C15 and a thickness of not less than 100mm, and shall not be less than 150mm in soft soil layers.

[0040] Step 3, FS101 waterproof sand plane construction

[0041] After the cushion construction is completed, carry out waterproof base treatment, search for cracks on the surface of the cushion, and immediately use FS101 waterproof cement mortar to block and smooth the surface cracks after discovery. It is required that during the const...

Abstract

The invention discloses a FS101, FS102 underground rigid composite waterproof construction method. The main process flow is as follows: excavating a foundation pit -> cushioning a concrete layer -> smearing a FS101 waterproof mortar -> binding steel bars -> pouring a FS102 waterproof concrete bottom plate, exterior wall and top plate -> smearing the FS101 waterproof mortar on the exterior wall ->backfilling soil. According to the construction method, the problems of low traditional construction speed and underground structure leakage are effectively solved, the method is easy and convenient to operate, an underground construction period is shortened, a waterproof cost of underground engineering is reduced, a waterproof guarantee degree of underground engineering can be improved, the waterproof life of underground engineering can be prolonged, and the reduction and conservation of power consumption, and green construction are really achieved.

Description

technical field [0001] The invention belongs to the technical field of underground waterproof construction, and in particular relates to an underground rigid composite waterproof construction method of FS101 and FS102. Background technique [0002] In recent years, with the large-scale development of construction projects, a large number of projects have gradually exposed various problems during construction or use. Among them, the leakage of underground structures is a common problem in buildings, and it is also a problem that affects the use of buildings. important question. At the same time, the traditional waterproof construction method has a long construction period and high construction cost, and due to the uneven settlement of deep foundation pits, the coiled material cracks occur from time to time, which seriously affects the quality of underground waterproofing. Contents of the invention [0003] The purpose of the present invention is to provide a FS101, FS102 u...
