Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to specific examples. The following examples are illustrative only and are not to be construed as limiting the invention. The examples, where specific techniques or conditions are not indicated, are to be construed according to the techniques or conditions described in the literature in the art or according to the product specifications.
The invention relates to a construction method for laying stone revetments, which comprises the following steps:
paying off: and determining the plane position of the revetment according to the normal water line on the construction design drawing, and widening 20cm on two sides of the foundation respectively to perform point distribution and line release.
Grooving: and excavating the foundation trench according to the positions of the distribution and the paying-off, wherein manual excavation is generally adopted, and mechanical excavation can be adopted when the engineering quantity is large. In order to ensure the construction safety, enough working surface is ensured during excavation, and the slope is released according to the regulations for the section needing to be released. The bank slope inclination can be corrected with wooden side slope templates.
Tamping the foundation: tamping the foundation trench, when meetting soft soil layer, laying the lime-soil that thickness is 14 ~ 15cm and carrying out the one deck and consolidate, the lime-soil is that the content proportion is 3: 7 lime and neutral clay;
pouring a foundation: the foundation is a revetment bearing part, and the mass of the upper part is transmitted to the foundation through the foundation, so that the foundation is required to be firm, the depth of embedding the foundation into the lake bottom is not less than 50cm, and if the soil quality is light, foundation reinforcement treatment is required; specifically, a rock block concrete foundation is adopted, rock blocks are tightly stacked and cannot be arranged at the edge of a foundation trench, and M15 or M20 cement mortar is poured to fully infiltrate gaps among the rock blocks, wherein the thickness of the foundation is 400-500 mm, and the height of the foundation is 0.6-0.8 time of the height of a revetment.
According to the embodiment of the invention, CaCl or NaCl can be added into the cement mortar for pouring the foundation in an amount of 3% -5% for preventing freezing.
Building a quay wall: adopt M5 cement mortar rubble as the quay wall, the brickwork joint width is 1 ~ 2cm, and the gap is colluded with cement mortar and is filled to for avoiding arousing the wall body to break because of the difference in temperature change, set up the expansion joint every 10 ~ 25M the waterproof material is filled in the expansion joint, makes it be less than the wall of building stones during the filling. Wherein, the waterproof material is one or more of lath, asphalt, asbestos cord, rubber, water stop or plastic.
According to the embodiment of the invention, the wall body of the quay wall is a main body part between the foundation and the coping and can also be built by concrete, rubble and bricks. The wall body bears the largest pressure mainly from vertical pressure, horizontal pressure of water and lateral pressure of soil behind the wall, and for this reason, the wall body needs to ensure a certain thickness, and the height of the wall body is determined according to the highest water level and the height of water surface waves.
Preferably, when the revetment has the discrepancy in elevation change, soil pressure behind the wall and the inhomogeneous change of ground subsidence etc. set up the settlement joint on the bank wall, the seam width is 20 ~ 30 mm.
Preferably, an underdrain is arranged behind the quay wall, gravels are filled to remove accumulated water behind the wall, and the wall body is protected.
Building and pressing a roof: the coping is the revetment top part, and the effect is that the reinforcing revetment is stable, prevents behind the wall soil loss, beautifies the water bank line, and is specific: and (3) building a coping by using a block stone or precast concrete plate with the width of 30-50 m, wherein the top stone is picked out 5-6 cm into water when being built, and the top surface of the top stone is higher than the highest water level by 50 cm. When the water level of the water body changes greatly, namely the water level is low at ordinary times and the water level is very high in rainy seasons, the upstream surface of the bank wall is made into a step shape so as to adapt to the rising and falling of the water level.
In conclusion, the revetment manufactured by the construction method for the stone revetment is firm and not easy to collapse, the settlement joints are arranged, so that the problems of uneven change of soil pressure behind a wall and foundation settlement and the like are solved, the expansion joints are arranged, so that the problems of wall body breakage and the like caused by temperature difference change are solved, and the revetment is low in manufacturing cost, easy to obtain materials, simple to construct, short in construction period and long in service life.
