Description

Be applied to soft capping protection architecture of open-air masonry ruins wall body

Technical Field

The utility model relates to a be applied to soft capping protection architecture of open-air masonry ruins site wall body belongs to the building restoration and protects technical field.

Background

The protection of the outdoor masonry site wall is usually combined with the development of the site park, and at present, the protection of the outdoor masonry site wall in China mainly comprises three types: backfilling protection, shed covering protection and hard covering protection.

Backfill protection is to completely bury the site into the soil, and the protection mode has minimum invasion to the site, but completely obstructs direct experience of tourists on the site. The secondary invasiveness is the canopy protection, but the physical and physical barriers formed by the canopy protection greatly impair the experience of the site park. The hard covering layer is used for protecting the end part of the site wall body by using lime, cement or lime-cement slurry, and when the material is in a plastic stage, the hard covering layer is horizontally coated on the end part of the site wall body, and when the material is hardened, a waterproof protective layer is formed. Compared with the former two protection modes, the hard covering layer has the advantages of minimum display interference on the site and the lowest cost, and is widely applied to the protection of the open-air masonry site in China.

The masonry wall exposed to the outside is most susceptible to various weathering attacks, particularly the top of the wall of the site is the place with the most serious site deterioration, and the damage is mainly caused by severe temperature change of the environment and freezing and thawing damage of extreme climate, so that the wall of the site is cracked and damaged, and then the whole wall of the site is damaged (the damage usually occurs on the top of the wall as shown in fig. 1). Although the hard cover protection is a common protection method, the incentive of the outdoor masonry site damage is not substantially relieved, and on the contrary, the damage of the outdoor masonry site is aggravated by the hard cover protection. As shown in the figure, when the wall of the site is cracked, if a waterproof hard cover layer is added to the wall (as shown in fig. 2), the cracking of the original site wall is usually accelerated after a period of time (as shown in fig. 3), which is mainly caused by the incompatibility of the thermal expansion coefficient and the strength of the new and old materials.

Preferably, the vegetation overburden includes horizontal root system turf layer and short root system turf layer, horizontal root system turf layer is established on the soil horizon, short root system turf layer is established on horizontal root system turf layer.

Preferably, the soil layer is a structure with a thick middle part and thin two sides.

Preferably, the short-root Crassulaceae vegetation system also comprises short-root Crassulaceae vegetation which is arranged on two sides of the masonry site wall body, has low requirements on moisture and soil and has a drooping effect.

Preferably, the thickness of the soil layer is 5 cm-20 cm.

Preferably, the soil of the soil layer is sterile soil.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses soft cover layer protection has the tile stone ruins site body of not disturbing like the software flowerpot to reversible advantage can effectively reduce the temperature variation at open-air tile stone ruins site wall body top, thereby does benefit to the permanent save of tile stone ruins site wall body, but wide application in the protection of tile stone ruins site wall body, like the wilderness great wall of china.

Compared with a hard cover layer, the soft cover layer has the remarkable advantages of solving the problem of cracking of the site wall body caused by temperature change and freeze-thaw damage, the site is protected in view, and the economic cost is more reasonable.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

The utility model discloses a through covering soil and short root system turf at masonry ruins wall body top, utilize the heat insulating ability and the natural moisture evaporation ability of vegetation overburden to reach control ruins wall body top temperature and humidity variation range, the temperature variation is the most important, reaches the purpose of protection ruins body. As shown in fig. 4, the utility model relates to a be applied to soft overburden protection architecture of open-air masonry site wall body is including laying soil horizon 1 at masonry site wall body 5 top, planting the vegetation overburden on soil horizon 1 to and plant and have the short root system Crassulaceae vegetation 4 that hangs down the effect simultaneously that hangs down on masonry site wall body 5 both sides to moisture and soil requirement are lower.

The soil of the soil layer 1 is sterile soil, the soil is paved into a structure with thick middle and thin two sides, and when the wall thickness of the site is 40-80cm, the soil layer 1 with the thickness of about 5-10cm is paved; when the thickness of the wall body of the site is more than 80cm, a soil layer 1 with the thickness of about 10cm-20cm is paved.

The vegetation overburden includes horizontal root system turf layer 2 and short root system turf layer 3, and horizontal root system turf layer 2 plants on soil horizon 1, and short root system turf layer 3 plants on horizontal root system turf layer 2, can fix with the bamboo nail. The short root system turf layer 3 can also be other short root system flowers and plants, but can not be woody plants.

The short root system Crassulaceae vegetation 4 can adopt the vegetation of sedum lineare and sunflower seeds which have lower requirements on water and soil and simultaneously have the drooping effect.

The utility model discloses replace the mortar to cover the hard cap layer at the top of masonry ruins wall body with the soft cap layer that soil and turf formed. The effect of the soft covering layer formed by the soil and the turf is equivalent to that of a heat preservation blanket, the temperature fluctuation of the head part of the masonry site wall body 5 is relieved, experiments prove that the temperature change of 7-10 ℃ can be effectively reduced by the soft covering layer protection in comparison with a hard covering layer under the extreme climatic environment, the wall head part of the open masonry site wall body 5 can be always kept above zero under the extreme climatic environment, and the masonry site wall body 5 is prevented from being frozen and thawed and damaged.

The technical key point of the soft cover layer protection lies in the selection and planting mode of the turf, the turf with the transverse root system growing rather than the longitudinal root system growing is selected when the turf is selected, the planting mode of the turf is also elaborated, and the root system of the turf can be ensured not to grow into a wall body through a certain planting mode.

Meanwhile, the vegetation of the soft cover layer also has a transpiration effect and can bring out excessive moisture inside the wall core of the masonry site wall body 5. Through the vegetation combination design, as shown in fig. 4, the short root system Crassulaceae vegetation 4 with hanging edges is planted on the wall edge of the masonry site wall body 5, so that the soft cover layer has a better water beating effect, the damage of rainwater to the wall body and the sagging pollution are reduced, and the soft cover layer has ornamental value.
