Abstract
The utility model relates to a joint structure of cement concrete paving, which is composed of diaphragm layers, a waterproof layer and a covering layer. The waterproof layer is arranged between two diaphragm layers, the covering layer is arranged on the waterproof layer, and waterproof materials in the waterproof layer form a powdery structure. The joint structure of cement concrete paving can ensure that joints can have favorable waterproof property under any adverse weather conditions and various working condition vibration, rain can be effectively prevented from penetrating the foundation of cement concrete paving, and early damage on the cement concrete paving is prevented.
Description
The utility model relates to a kind of new form of structure of cement concrete pavement seam.
At present, be the device of shifting block type structure with cement concrete as the road surface.And the seam between two road surfaces of its device of shifting block type structure generally adopts pitch to fill up.This is because pitch has easy construction first, second has nature ductility, can remedy the gap of the seam that causes because of expanding with heat and contract with cold, and prevents that rainwater from entering the basis of cement concrete, destroys advantages such as road surface.Yet thisly also exist a fatal shortcoming with pitch as joint filler: promptly, during the broiling summer, pavement temperature is too high, and pitch at high temperature dissolves easily, and runs off, and causes and produces the gap in the seam; In the winter time, pitch at low temperatures, and is easily dry and cracked again and produce the crack, the two is in rainy season, rainwater is easy to the gap in the seam or the basis of crack water leaking-in cement concrete, thereby causes the premature failure of cement concrete pavement, influences normally carrying out of communications and transportation.
Problem in view of above-mentioned existence, the purpose of this utility model provides a kind of energy and adapts to various adverse weather conditions, and has a good water resistance, can stop rainwater water leaking-in cement concrete road bed effectively, prevent the cement concrete pavement seam new construction of cement concrete pavement premature failure.
The concrete structure of cement concrete pavement seam new construction described in the utility model as shown in drawings
Fig. 1 is a structural representation of the present utility model
Below with reference to the accompanying drawings specific embodiments of the present utility model is elaborated:
Cement concrete pavement seam new construction is made up of membrane layer 2, waterproofing course 3 and covering layer 4.Waterproofing course 3 is arranged between two membrane layers 2, covering layer 4 be arranged at waterproofing course 3 above, the thickness of covering layer 4 is advisable to maintain an equal level with the road surface.Waterproofing materials in the waterproofing course 3 is granular structure.Covering layer 4 adopts pitch, cement mortar, plastics, iron powder binder to make.Membrane layer 2 can adopt plastic sheeting, fabric etc.
Specific implementation process of the present utility model is: lay one deck by plastic sheeting in the bottom of seam 1 earlier, the membrane layer 2 that fabric etc. are made, then on membrane layer 2, add the waterproofing course 3 that powdery waterproof material is formed, and on waterproofing course 3, add one deck membrane layer 2, at last, adding covering layer 4 again on membrane layer 2 is sealed.Because the material in the waterproofing course 3 is the loose structure of the drying of powdery, increase or dwindle when vibrating when the width in slit, road surface changes with climate temperature with plate structure, its molecule degree promptly can rearrange distribution, and make the waterproof powder of powdery be adsorbed in the slotted wall all the time, the hydrophobicity performance that had of waterproof powder itself in addition, thereby can guarantee that pavement joint is under any adverse weather condition and under the vibration of various operating mode, all has favorable waterproof property, and stop rainwater water leaking-in cement concrete road bed effectively, prevent the cement concrete pavement premature failure.
The utility model is skillfully constructed, novel structure, and it has not only solved the problem that the cement concrete pavement seam is leaked effectively, and is widely used in the antiseep problem in building construction crack.
