Problems solved by technology

[0004] Among these three types of permeable bricks, pavement bricks made of ceramic materials consume more energy during production; pavement bricks made of cement permeable concrete are difficult to meet the frost resistance standards and are not suitable for use in northern regions; special shapes are used to form permeable channels. Pavement brick production equipment and paving process are complex
Moreover, these three types of permeable bricks all have the disadvantage of higher prices.
[0005] Another potential risk is: in order to ensure the firmness and aesthetics of the paved ground, most of the construction units use the method of sitting mortar paving, that is, cement mortar is used to bond permeable bricks to mortar with poor water permeability. Cushion
In this way, the so-called permeable ground paved with most permeable bricks cannot play its due role in permeable water.

Embodiment 1

[0026] Example 1, such as figure 1 , figure 2 and Figure 6 as shown in:

[0027] Laying method of the present invention comprises the steps:

[0028] A: First, lay a water storage gravel layer on the road base according to the design requirements. The water storage rate of the gravel layer is 40%, and the gravel layer should be compacted and rolled flat;

[0029] B: Lay a dry hard cement mortar cushion on the water-storage gravel, and then lay ordinary pavement bricks 1 by using ordinary cement mortar to sit and fill the joints; in this embodiment, the most commonly used square pavement is used Pavement bricks, because the brick seam 3 of its laid pavement is in the shape of "well", that is, the joints of its assembled joints are in the shape of "ten".

[0030] C: When the dry and hard cement mortar cushion is not dry, nail the permeable positioner 2 into the node of the brick joint 3; in order to make the laying more efficient, use the steel drill 8 to nail the permeabl...

Embodiment 2

[0033] Example 2, such as image 3 as shown in:

[0034] This embodiment is used in the case where the permeable pavement brick is a rectangular pavement brick. The cross-sectional shape of the permeable locator is a T-shaped permeable locator 5, and its hollow part 51 is also a T-shaped structure; The permeable locator is nailed into the node of the brick joint, and the cross-sectional shape of the drill bit of the steel drill should be the same as the cross-sectional shape of the hole 51 of the permeable locator, so that when the steel drill is used, the drill bit of the steel drill can be inserted into the hollow of the permeable locator , That is, in this embodiment, the cross-sectional shape of the drill bit of the steel drill is also T-shaped.

[0035] Other parts of this embodiment are identical to Embodiment 1.

Embodiment 3

[0036] Example 3, such as Figure 4 Shown:

[0037] This embodiment is used in the occasion where the permeable pavement is paved with regular octagonal pavement bricks and regular quadrilateral pavement bricks. The cross-sectional shape of the permeable positioner is Y-shaped, and the Y-shaped shape is formed by a right angle and two 135° obtuse angles. Y-shaped structure. When a steel drill is used as a nailing tool, the cross-sectional shape and size of the drill bit part are the same as the cross-sectional shape of the hole 61 of the permeable positioner.

[0038] Other parts of this embodiment are identical to Embodiment 1.

Abstract

The invention relates to a method for paving water-permeable brick-paved ground and a water permeation locator, and belongs to the technical field of rod pavement. The method comprises the following steps of: paving a water-storing crushed rock layer, and tamping and rolling flatly the water-storing crushed rock layer; paving a dry and hard cement mortar bedding cushion layer on the water-storing crushed rock layer, and paving normal pavement bricks by adopting a normal cement mortar bed-pulp paving in a jointing manner; nailing the water permeation locator into a node of each brick joint; and finishing the brick joints; The water permeation locator is a hollow abnormal tube, the shape of the section of the hollow abnormal tube is cross or Y or T, and an inner chamfered angle is arranged at one end of the hollow abnormal tube. According to the method for paving the water-permeable brick-paved ground, disclosed by the invention, the high-efficiency water-permeable ground is paved by utilizing the normal pavement bricks so that the cost is greatly reduced; the construction is simple, the water-permeable ground can be paved in a bed-pulp manner, an amount of engineering is beneficial to being improved, and the water permeation effect is excellent. The water permeation locator disclosed by the invention has the advantages of convenience and easiness for machining and using.

Description

Technical field: [0001] The invention relates to a method for laying a permeable brick-paved ground and a permeable positioner, belonging to the technical field of road laying. Background technique: [0002] At present, hardened grounds such as squares in cities, sidewalks on roads, and residential roads are mostly paved with non-permeable materials such as stone, porcelain square bricks, concrete pavement bricks, and asphalt concrete. This hardened ground blocks the back seepage of rainwater, causes the urban groundwater table to drop, depletes groundwater resources, causes uneven ground settlement, aggravates urban rain and flood disasters, and intensifies the urban heat island effect. [0003] With the popularization of the concept of environmental protection, some hardened floors in some cities have been paved with permeable bricks and other materials to form permeable floors. The existing permeable bricks are divided into three categories: 1——use ceramic materials to s...
