Abstract

The invention relates to a method for using plastic drainage plates as a hollow floor of underground engineering base plates. According to the method, the plastic drainage plates are used as the hollow concrete floor of the indoor underground engineering base plates and used for drainage and moisture insulation, and thus the purpose of engineering water resistance can be achieved. The method relates to multiple items of content such as structural plane slope finding, drainage ditch and drainage plate product connection modes and construction technologies. First, a slope is found on the surface of the structural bottom plates, when the structure surface is an integral plane, leaking water enters a water collection well, and cleaning water firstly enters a drainage ditch and then enters the water collection well. The self-sticking plastic drainage plates have rolled hollow fulcrums and bonded through adhesive tape or connected in an overlapped mode, joint strips are arranged between the drainage plates and the wall, and concrete can be poured and pounded at two times or at one time in the final construction. The fulcrums of the drainage plates are made to be square, polygonal or prismatic, concave and convex reinforcing ribs are arranged on the side faces of the fulcrums, and the fulcrums can be arranged in an orthogonal row and column or crossed row and column mode.

Description

Of plastic draining board, make the method for underground construction base plate hollow terrace

Technical field

The invention belongs to buildings waterproof scope, particularly the indoor position of underground construction base plate is done hollow concrete terrace with plastic draining board and is reached engineering waterproofing object for draining, damp proof insulation, comprises structural plane and look for slope, gutter, band drain product, connecting mode and the multinomial independent claims of construction technology in this total invention of underground construction base plate draining damp proof insulation.

Background technology

< < water-proof technology of underground projects rules > > GB50108-2008, waterproof guard be " 1, cut and cover method underground construction one-level, should select waterproof concrete and waterproofing materials together with other; 2, hidden construction process underground construction one-level, should select liner structure and a kind of waterproofing materials ".The present invention be directed to cut and cover method underground construction, this project all wants to do in addition at the chamber internal surface of structure base slab the concrete terrace that one deck 50～300mm is thick again, the present invention makes void layer exactly between deck and surface layer, can get rid of percolating water, reaches construction work permanent waterproof damp proof insulation object.

Summary of the invention

First analyze source and the drainage direction of percolating water, the percolating water of structure base slab is to flow to collecting well in the surface void layer of deck, take collecting well edge as ± 0.00 measurement total face, on structure base slab surface, to have 30～200mm high look for slope, make underground leakage water naturally flow into collecting well.

Water pipe all will be let slip in every partition wall, threshold and gutter of drainage line of stopping up, and makes current unimpeded.Also will solve the relation in ground cleaning water and gutter: when body structure surface is integral planar, the percolating water of base plate enters collecting well from void layer, ground cleaning water enters gutter and flows into collecting well; When body structure surface has recessed gutter, base plate leakage water enters gutter and collecting well from void layer, and ground cleaning water enters gutter, then enters collecting well.

The plastic draining board of the hollow fulcrum of web-like is that drum-type is produced continuously, squeezes into one～tetra-butyl adhesive tape during production, self-adhesion at normal temperatures, and the release paper slip of adhesive tape upper cover, is self-adhesion plastic draining board.Can hasp about during construction one row's fulcrum bonding or dull and stereotyped superimposed bonding; Front and back hasp one row's fulcrum of band drain, a sticky adhesive tape in the plane between fulcrum.In order to make plastics fulcrum have enough compressive strength to bear working load, fulcrum is done to squarely, polygon, prismatic, there is concavo-convex ribbed stiffener fulcrum side, and it can be quadrature housing in row that fulcrum is arranged, and can be also intersection housing in row.The connection of above plastic draining board can, without viscose glue, be also only all around hasp one row's fulcrum.

At the band drain unifying and wall joints position, in order to prevent concrete spillage, then paste plastic board or a foam lath that 30～100mm is wide, fill and lead up gap.Then be to wire-tie to water concrete surface layer, on the band drain unifying, first hollow fulcrum leveled up with concrete, after maintenance, wire-tie again, after watering whole concrete or directly wire-tiing on plastic plate, property is watered concrete surface layer again.

The specific embodiment

Fig. 1 underground construction base arrangement is analysed and observe and is seen, take the edge (4) of collecting well (2) is ± 0.00, on structure base slab surface (1), to have 30～200mm high look for slope (3), make underground leakage water naturally flow into collecting well.

Fig. 2 a body structure surface (1) is integral planar, the percolating water of base plate enters collecting well (2) from void layer (5), from gutter, (6) flow into collecting well (2) to ground cleaning water, should bury water pipe (7) in the sloping layer in gutter.Fig. 2 b works as body structure surface (1) recessed gutter (8), and base plate leakage water enters gutter (8) and collecting well (2) from void layer (5), and ground cleaning water enters gutter (8) and enters collecting well (2) again.

Fig. 3 a, Fig. 3 b, Fig. 3 c adopt polyethylene drainage plate (9), squeeze into one～tetra-adhesive tape (10) about during production to cover release liners, tear release liners left and right can hasp one row's fulcrum bonding during construction.Fig. 3 d is that left and right is dull and stereotyped superimposed bonding.
