Problems solved by technology

There are often no transportation roads in high cutting slopes. Due to the substantial increase in labor wages, the labor cost of constructing the rapid flow trough of mortar rubble has been greatly increased. In addition, the manual transportation of rubble also requires a large manual transportation fee, which makes it impossible. Under the condition of transporting rubble by means of transportation, the construction cost of the rapid flow trough of mortar rubble will increase, and the construction period will also greatly increase
Especially when the slope is reinforced with a flexible support structure, the rapid flow trough constructed on the flexible support structure is prone to cracking and damage due to the deformation of certain parts of the flexible support structure, and thus also There will be a problem that the repair of the rapids will be difficult

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] see figure 1 and figure 2 The structure of the prefabricated concrete half-culvert jet trough includes four parts: bottom fixed mortar 1, concrete prefabricated half-culvert pipe 2, large arc-shaped energy-dissipating steps 9, small-arc-shaped energy-dissipating steps 10, and two ditches 3 at the top. A concrete prefabricated half-culvert pipe 2 is arranged on the bottom fixed mortar 1, and a small arc-shaped energy-dissipating step 10 with an arc height of 40 mm to 60 mm is provided in the middle of the groove bottom of the single-section concrete prefabricated half-culvert pipe 2, preferably with a height of 50 mm. The joints of two concrete prefabricated half-culvert pipes 2 are provided with arc-shaped energy-dissipating steps 9 with an arc height of 180 mm to 220 mm. Bottom fixing mortar 1 adopts M7.5 cement mortar, width 4 shoul...

Abstract

The invention discloses a chute structure for a concrete precast semi-culvert. According to the chute structure for the concrete precast semi-culvert, disclosed by the invention, the concrete precast semi-culvert (2) is arranged on bottom fixing mortar (1), a small circular-arc energy dissipation step (10) with the arc height of 40-60mm is arranged in the middle of the groove bottom of the concrete precast semi-culvert (2), a large circular-arc energy dissipation step (9) with the arc height of 80-220mm is arranged at the joint part of the two sections of the concrete precast semi-culvert (2), and a groove side (3) is arranged on each of the two sides of the concrete precast semi-culvert (2). Compared with the mortar flag stone chute structure, the chute structure for the concrete precast semi-culvert can be rapid in construction and also has the remarkable advantages of low coat, easiness in maintenance and the like.

Description

technical field [0001] The invention relates to a drainage structure for road slopes, in particular to a concrete prefabricated semi-culvert rapid trough structure. Background technique [0002] On high embankments or high cutting slopes with a length of more than 100 meters, in order to drain the surface water collected in the intercepting ditch and the platform side ditch at all levels to the subgrade side ditch and prevent the erosion of the slope by rainfall, generally the There is more than one rapid flow trough in the middle of the face. At present, in the high embankment or high cutting slope of expressway in our country, the rapid flow trough of mortar rubble is often used. There are often no transportation roads in high cutting slopes. Due to the substantial increase in labor wages, the labor cost of constructing the rapid flow trough of mortar rubble has been greatly increased. In addition, the manual transportation of rubble also requires a large manual transport...
